Find the product of (x + 5)(x − 5).
Answer:
x² - 30 + 5x
Step-by-step explanation:
(x + 5)(x − 5)
=x(x − 5)+5(x − 5)
=x² - 5 + 5x - 25
=x² - 30 + 5x

What is the measure of angle 2?
Answer: Angle 2: 45°
Step-by-step explanation:
All triangles add up to 180, so all you would so is take both of those angles and subtract them from 180, so basically 180 - 135
Solve the equation
-3x + 1 + 10x = x + 4
0 x = 1/2
х
=
x = 12
X = 18
Answer:
x = 1/2Step-by-step explanation:
-3x + 1 + 10x = x + 4
-1 -1
7x = x + 3
-x -x
6x = 3
÷6 ÷6
x = 1/2
4= -2(x-2) +4 please help I’ll give you points!
4 = -2(x-2) + 4
or, 4 = -2x + 4 + 4
or, 4 = -2x + 8
or, 4 - 8 = -2x
or, -4 = -2x
or, -4/-2 = x
or, 2 = x
Answer:The value of x is 2.
Answer:
x = 1
Step-by-step explanation:
4 = -2( x - 2) + 4
4 = -2x - (-2) +4
4 = -2x + 2 + 4
4 = -2x + 6
4 - 6 = -2
6 - 6 = 0
-2 = -2x
x = 1
hopefully this helps you get it right and if it does pls mark as brainlest ( it really helps if you do). :)
At a track meet, the 3 members of a relay race ran a total distance of 3/8 of a mile. if each runner ran the same distance. how far did each person run?
Answer:
.125 of a mile
Step-by-step explanation:
If the total distance was 3/8 of a mile and there were 3 runners, then each runner ran ___________________.
Change the 3/8 to a decimal
3/8 = 0.375 of a mile
Since there were 3 runners divide the total distance by 3
0.375/3 = 0.125
Each runner ran 1/8 of a mile or 0.125 of a mile.

Step-by-step explanation:
[tex](2x + 23) + (9x - 5) = 11x + 18 \\ 11x + 18 = 95 \: \: \: \: 11x = 77 \\ x = 7 \\ abd = (2 \times 7) + 23 = 37 \\ dbc = (2 \times 9) - 5 = 13[/tex]
Answer:
x=7
m<ABD=37°
m<DBC=58°
Step-by-step explanation:
Add the two equations. They need to equal 95. Solve for x.
(2x+23)+(9x-5)=95
11x+18=95
11x=95-18
11x=77
x=7
Substitute 7 in for x to both equations to solve for the angle degrees.
m<ABD=2x+23 = 2(7)+23 = 14+23 = 37
m<DBC=9x-5 = 9(7)-5 = 63-5 = 58
CHECK: 37+58=95

Which is a y-intercept of the continuous function in the table? (0, –6) (–2, 0) (–6, 0) (0, –2)
Answer:
(0, - 6)
Step-by-step explanation:
The y- intercept is where the function crosses the y- axis.
This occurs when x = 0 , thus
From the table when x = 0, f(x) = - 6
The y- intercept is therefore (0, - 6 )
Answer:
(0, - 6)

Which of the quadratic functions listed is written in standard form?
O A. Y= 2x² + 3x - 5
O B. Y-4 = - 3(x - 5)
OC. Y - 7 = -2(x + 3)?
O D. Y= (x+1)(x – 5)
Answer: A
Step-by-step explanation:
f(x)=ax²+bx+c is the standard form for quadratic functions. Looking at the answer choices, we can eliminate B, C, D. They are not the same as the given standard form. B and C are point-slope formulas, which are not standard form. D is in intercept form, therefore it is not standard form. This leaves us with A as the correct answer.

Answer:
zack won. if you compare the decimal equivalents of their scores, -3.666<-3.625
Step-by-step explanation:
given: vanessa and zack are playing a game where the player with the lower score wins
score of vanessa=
[tex] - 3 \frac{5}{8} = - ( \frac{29}{8}) = - 3.625 [/tex]
score of zack:
[tex] -3 \frac{2}{3} = - ( \frac{11}{3} ) = - 3.666[/tex]
we can see -3.666<-3.625
zack has the lower score
Answer:
zack won. if you compare the decimal equivalents of their scores, -3.666<-3.625

In this question, we are required to find
[tex]2 {x}^{2} - 3x {y}^{3} [/tex]
When, x = -2 and y = -1
We just need to plug the values of x and y in the given polynomial to get our required answer.
Given, Polynomial in variable x and y,
[tex]2 {x}^{2} - 3x {y}^{3} [/tex]
Plugging values of x and y,
[tex]2 {( - 2)}^{2} - 3( - 2)( - 1) {}^{3} [/tex]
According to PEMDAS, we need to do the exponents first, So let's simplify the exponents,
[tex]2(4) - 3( - 2)( - 1)[/tex]
Opening the parantheses and finding the answer,
[tex]2 \times 4 - 3 \times - 2 \times - 1[/tex]

3. ( did not know how to crop, please ignore this question! )
Thank you so much!
Answer:
See Explanation
Step-by-step explanation:
m = 46° (vertical angles)
j = 92° (vertical angles)
j + k + 46° = 180° (staright line angles)
92° + k + 46° = 180°
138° + k = 180°
k = 180° - 138°
k = 42°
n = 37° + 44° = 81°
A weather balloon ascended from an elevation of 18 feet below sea level to an elevation 19 1/2 feet above sea level. What distance dd the weather balloon rise?
Answer:
The ballon rose a distance of 37 1/2 feet
Step-by-step explanation:
Here, we are interested in calculating the level of ascent of the weather balloon.
From the question, we are told that the ballon made a transition from below the sea to above the sea.
Now to calculate the total distance, we shall
be adding the distances below the sea and the distances above;
Mathematically, that would be;
18 feet + 19 1/2 feet = 37 1/2 feet

Answer:
Interquartile range = 40
Step-by-step explanation:
interquartile range = Q3-Q1
It has 7 numbers, in order to make it even we remove the middle number (70) to make two sets of quartiles
Q1 = 50 (middle of the lower quartile)
Q3= 90 (middle of the higher quartile)
