Hey there! :)
Answer:
y = 5x + 10
Step-by-step explanation:
From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:
[tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Plug in the points:
[tex]m= \frac{10 - 0}{0 - (-2)}[/tex]
Simplify:
[tex]m= \frac{10}{2}[/tex]
m = 5.
The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:
y = 5x + 10 is the equation written in slope-intercept form.
Answer:
y=5x+10
Step-by-step explanation:
The base form of the equation is y=mx+b
B is always the y intercept so we can plug that in
y=mx+10
Then we can fine the slope by using the gradient formula
Change in y over change in x
The two points are (-2, 0) and (0, 10)
The result is 10/2 which can be simplified to 5
y=5x+10
Gabriel note sur une frise chronologique les événements familiaux importants. Il utilise des entiers positifs ou négatifs. Pour écrire une date avant sa naissance, il utilise des nombres négatifs et pour une date après sa naissance, des nombres positifs. Par exemple, la mère de Gabriel a reçu une médaille en l'an -20−20minus, 20 et la sœur de Gabriel est née en l'an +5+5plus, 5. Que représente l'année 0~?0 ?0, space, question mark Réponse : Réponse : L'année où la sœur de Gabriel est née L'année de la naissance de Gabriel L'année où la mère de Gabriel a reçu une médaille
Answer:
L'option B est correcte. Le chiffre 0 représente l'année de naissance de Gabriel.
Option B is correct.
The number 0 represents the year when Gabriel was born.
Step-by-step explanation:
Il a été déclaré dans la question que Gabriel a enregistré des événements tge dans leur vie par rapport à quand il est entré en scène. Avec des exemples notables donnés pour illustrer que les nombres négatifs indiquent les temps avant la naissance de Gabriel et les nombres positifs indiquent les années après la naissance de Gabriel.

J'espère que cela t'aides!!!
English Translation
Gabriel notes on a timeline important family events. It uses positive or negative integers. To write a date before his birth, he uses negative numbers and for a date after his birth, positive numbers. For example, Gabriel's mother received a medal in the year -20 and Gabriel's sister was born in the year + 5. What does the year 0 represent? Answer:
A) The year when Gabriel's sister was born
B) The year when Gabriel was born
C) The year when Gabriel's mother received a medal
Solution
It was stated in the question that Gabriel recorded tge events in their lives relative to when he came into the picture. With noticeable examples given to illustrate that the negative numbers indicate times before Gabriel's birth and positive numbers indicate years after Gabriel's birth.
Hence, it is straighforward to see that the year 0 in relative terms to Gabriel's birth will represent the year in which Gabriel was born.

What value of x is in the solution set of –2(3x + 2) > –8x + 6
Answer:
5 <x
Step-by-step explanation:
–2(3x + 2) > –8x + 6
Divide each side by -2, remembering to flip the inequality
–2/-2(3x + 2) < –8x/-2 + 6/-2
3x+2 < 4x-3
Subtract 3x from each side
3x-3x+2 < 4x-3x-3
2 < x-3
Add 3 to each side
2+3 < x-3+3
5 <x
Answer:
Step-by-step explanation:
-2( 3x + 2) > -8x + 6
-2*3x + (-2)*2 > -8x + 6
-6x - 4 > -8x + 6
Add 4 to both sides
-6x - 4 + 4 > -8x + 6 + 4 { add like terms}
-6x > -8x + 10
Add 8x to both sides
-6x + 8x > - 8x + 10 + 8x
2x > 10
Divide both sides by 2
2x/2 > 10/2
x > 5

What is the factored form of n2 – 25?
Answer: (n + 5)(n - 5)
Explanation: In this problem, we have a binomial that's the difference of two squares because n² and 25 are both perfect squares and we are subtracting or taking the difference of these two squares.
Since the difference of two squares factors as the product of two binomials, we can setup our parenthses and in the first position, we use the factors of n² that are the same which are n · n.
In the second position, we use +5 and -5 as our factors of -25.
So our answer is (n + 5)(n - 5).

Triangle D E F is shown. The length of E F is 10, the length of D F is 7, and the length of D E is 12. What information relevant to calculating area do we have available for this triangle? Which method should we use to calculate the area for this triangle? What is the area of this triangle calculated to the nearest hundredth of a square unit?
Answer:
34.98 square units.
Step-by-step explanation:
It is given that DEF is a triangle, EF=10, DF=7 and DE=12.
Information of sides of triangle is relevant to calculating area.
We should use Heron's formula.
According to Heron's formula, the area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]
where,
[tex]s=\dfrac{a+b+c}{2}[/tex]
For triangle DEF, let a=10, b=7 and c=12.
Now,
[tex]s=\dfrac{10+7+12}{2}=\dfrac{29}{2}=14.5[/tex]
Area of triangle is
[tex]A=\sqrt{14.5(14.5-10)(14.5-7)(14.5-12)}[/tex]
[tex]A=\sqrt{14.5(4.5)(7.5)(2.5)}[/tex]
[tex]A=\sqrt{1223.4375}[/tex]
[tex]A=34.977671[/tex]
[tex]A\approx 34.98[/tex]
Therefore, the area of triangle DEF is 34.98 square units.
Answer:
SSS, Heron's formula, and 34.98 square units
Step-by-step explanation:
Assume that all triangles have interior angles less than 90°.A surveyor sights on a survey marker that is 132.3m distant. She needed to turn her transit (her survey instrument) 75° to sight on a second survey marker. She knows that from the second marker, the angle between the line of site from her own position and the first marker is 68°. How far is she from the second marker?
Answer:
85.9 m
Step-by-step explanation:
The law of sines can help figure this.
The remaining angle in the triangle is ...
180° -75° -68° = 37°
This is the angle opposite the leg from the surveyor to the second marker. Referencing the attachment, we have ...
b/sin(B) = c/sin(C)
b = sin(B)·c/sin(C) = 132.3·sin(37°)/sin(68°) ≈ 85.873 . . . meters
The surveyor is about 85.9 meters from the second marker.
Which of the following is the graph of a linear function?
Answer:
The first one.
Step-by-step explanation:
A linear function is a straight line, regardless of direction.
The first graph is of a linear function.
The phrase linear function denotes to function which is linear, specifically of this form:
[tex]f(x) = mx + c[/tex]
This is also written as:
[tex]y = mx + c[/tex]
It is written so that we can take the outputs of the function f(x) in a separate variable for further mathematical treatments with ease.
Now when that second equation is plotted on XY plane, you get a straight line graph since this is the equation form of any straight line, in geometry.
All the straight lines are covered under y = mx + c linear function form.
Since the first graph contains a plot of straight line, thus the first graph is of linear function.
The second graph is of downwardly opened vertical parabola which is of degree 2, thus not linear.
Thus first graph is the graph of a linear function.

find the value of x A. does not exist B. -7 C. 26 D. 35
Answer:
A-does not exist
Step-by-step explanation:
The pythagorian theorem :
12²+x²= (x-2)²144+x²= x²-4x+4144-4+x²-x²= -4x 140 = -4x x = 140/-4x= -35That's absurd . A side cannot be negative since it's a distance
It was obvious from the beginning since one of the sides is greater than the hypotenus wich is impossible x≥x-2
Answer:
A. does not exist
Step-by-step explanation:
Since this is a right triangle we can find the value of x using Phytagorian Theorem
(x-2)^2 = 12^2 + x^2
x^2 -4x + 4 = 144 + x^2 (x^2 will be eliminated)
-4x = 144
x = -36 since the side lengths cannot be negative we select the option A which says it doesn't exist.

The mean age of 8 women in an office is 20 years old. The mean age of 12 men in an office is 32 years old. What is the mean age (nearest year) of all the people in the office? Answer it please because it would be helpfull alot
Answer:
27.2
Step-by-step explanation:
The mean age of 8 women in the office is 20 years old
The mean age of 12 men in an office is 32 years old
The first step is to calculate the mean of the both the men and women in the office, that way we will be able to know the sum.
The mean of the women can be calculated by taking the sum of the value and dividing by the number
= 20+20+20+20+20+20+20+20/8
= 160/8
= 20
The mean of the men can be calculated by taking the sum of the values and dividing by the number
=32+32+32+32+32+32+32+32+32+32+32+32/12
= 384/12
= 32
Therefore, to find the mean age of people in the office we add the sum of both the men and women and divide by the total number of people in the office
= 384+160/20
= 544/20
= 27.2
Hence the mean age of people in the office is 27.2

Answer:
(4, 4 )
Step-by-step explanation:
Given the 2 equations
y = x² - 6x + 12 → (1)
y = 2x - 4 → (2)
Substitute y = x² - 6x + 12 into (2)
x² - 6x + 12 = 2x - 4 ( subtract 2x - 4 from both sides )
x² - 8x + 16 = 0 ← in standard form
(x - 4)² = 0 ← in factored form
x - 4 = 0 ⇒ x = 4
Substitute x = 4 into (2) for corresponding value of y
y = 2(4) - 4 = 8 - 4 = 4
Solution is (4, 4 )

Graph g(x), where f(x) = 2X - 5 and g(x) = f(x + 1).
(g(x)
0
g(x)
0
0
Answer:
Please refer to the attached image for the graph of g(x).
Step-by-step explanation:
First of all, let us find the value of g(x).
Given that:
[tex]f(x) =2x-5[/tex] and
[tex]g(x) = f(x+1)[/tex]
To find: The graph of g(x) = ?
Solution:
[tex]f(x+1)[/tex] means we replace 'x' with 'x+1' and we get g(x).
Let us replace x with x+1 in f(x):
[tex]f(x+1) = 2(x+1)-5\\\Rightarrow f(x+1) = 2x+2-5\\\Rightarrow f(x+1) = 2x-3\\\therefore g(x) = 2x-3[/tex]
Now let [tex]y=g(x) =2x-3[/tex]
Let us put x = 0 and then y = 0 to find two points on coordinate axis to easily plot the graph of g(x).
Putting x = 0,
[tex]y=2\times0-3\\\Rightarrow y =-3[/tex]
So, one point is A(0,-3)
Now, let us put y = 0 and find out x.
[tex]0=2x-3\\\Rightarrow x=\dfrac{3}{2}[/tex]
So, second point is [tex]B(\frac{3}{2},0)[/tex].
Now, let us plot A and B then extend the line joining AB.
Please refer to the attached image for the graph of function:
g(x) = 2x - 3
