Identify an equation of a line in slope-intercept form that passes through (1, 2) with a slope of -8
Answer:
y = -8x + 10
Step-by-step explanation:
y = -8x + b
2 = -8(1) + b
2 = -8 + b
10 = b
9514 1404 393
Answer:
y = -8x +10
Step-by-step explanation:
The y-intercept can be found from the equation ...
b = y -mx
Using the given point and slope, this is ...
b = 2 -(-8)(1) = 10
Then the slope-intercept equation is ...
y = mx +b
y = -8x +10

finding the axis of symmetry of its graph y=3x^2-18x+1
Answer:
x=3
Step-by-step explanation:
Answer:
x = 3
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
y = 3x² - 18x + 1 ← is in standard form
with a = 3, b = - 18
x = - [tex]\frac{-18}{6}[/tex] = 3
Axis of symmetry is x = 3
You ride an express bus from the center of town to your street. You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. Option B is to pay $2.30 per ride. After how many rides will the total costs of the two options be the same?
Answer:
20 rides
Step-by-step explanation:
Let x represent how many rides you take.
Option A's cost can be represented by 0.8x + 30.
Option B's cost can be represented by 2.3x.
Set these expressions equal to each other, then solve for x:
0.8x + 30 = 2.3x
30 = 1.5x
20 = x
So, the costs will be the same at 20 rides

Step-by-step explanation:
plug in some x values to test:
4(0) + 3 = 0 + 3 = 3
4(3) + 3 = 12 + 3 = 15
4(6) + 3 = 24 + 3 = 27
it checks out
Answer:
It would be the last one
Step-by-step explanation:
here are the coirdantes:
0-3
3-15
6-27
9-39
So if u try the first one
f(x)=x+3
3(1)=3
3+3=9
So it does not work
The second choice:
f(x)=-4x-3
3(-4)
-12-3=-15
It does not work
The third choice:
f(x)=1/4x+3
3(1/4)=3/4
3/4+3=3 3/4
The last one:
f(x)=4x+3
9(4)=36
36+3=39
As you can see the last one works

Solve for q. Write your answer as “q=___”
Answer:
7q-46= 3q +6
7q-3q = 6+ 46
4q= 52
4q/4= 52/4
q= 13
Answer:
Hello! q = 22
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees so...
22 × 7 = 154 154 - 46 = 108
3 × 22 = 66 66 + 6 = 72
108 + 72 = 180 therefore q = 22 hope that helps!

Select the correct answer.
Consider the explicit formulas for two sequences.
f(n) = 2(1 – 1) - 1
g(n) = 3n + 6
Which mathematical statement is correct?
O A. 96) > 6)
O B. (7) > g(10)
OC. F(5) < g(3)
O D.g(8) = f(5)
Answer:
[tex](c)\ f(5) < g(3)[/tex]
Step-by-step explanation:
Given
[tex]f(n) = 2(n-1) -1[/tex]
[tex]g(n) = 3n + 6[/tex]
Required
Which is correct
[tex](a)\ g(6) < f(6)[/tex]
Calculate g(6) and f(6)
[tex]f(n) = 2(n-1) -1[/tex]
[tex]f(6) = 2(6 - 1) -1 = 2*5-1=9[/tex]
[tex]g(n) = 3n + 6[/tex]
[tex]g(6) =3*6 +6 =24[/tex]
(a) is false, because g(6) > f(6) i.e. 24 > 9
[tex](b)\ f(7) > g(10)[/tex]
Calculate f(7) and g(10)
[tex]f(n) = 2(n-1) -1[/tex]
[tex]f(7) = 2*(7-1)-1=2*6-1=11[/tex]
[tex]g(n) = 3n + 6[/tex]
[tex]g(10) =3*10+6=36[/tex]
(b) is false, because f(7) < g(10) i.e. 11 <36
[tex](c)\ f(5) < g(3)[/tex]
Calculate f(5) and g(3)
[tex]f(n) = 2(n-1) -1[/tex]
[tex]f(5) =2 *(5-1)-1 = 2*4-1=7[/tex]
[tex]g(n) = 3n + 6[/tex]
[tex]g(3) = 3*3+6=9+6=15[/tex]
(c) is true, because f(5) < g(3) i.e. 7 <15
Answer:
the answer is f(7) > g(10) because 63 > 36.

What expression is equivalent to
Answer:
c) x^6 y^11 z^6
Step-by-step explanation:
When multiplying exponents with the same variables, you add them.
so x^4(x^2) would be 4+2 and therefore x^6.
keep in mind this doesn't apply for different variables
(xy^2)(x^2y) will not be added!!

The distance far up the side of the house will the ladder reach now will be 15.2 feet.
The distance far up the side of the house will the ladder reach now will be 15.2 feet.
A 40 foot ladder is set against the side of a house so that it reaches up 24 feet.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Let the distance between the base of house and ladder foot is x feet.
By using Pythagoras theorem;
40² = 24² + x²
⇒ 1600 - 576 = x²
⇒ x² = 1024
⇒ x = 32 feet
If Lily grabs the ladder at its base and pulls it 4 feet farther from the house.
Then, the distance between the base of house and ladder foot = x + 5
Height of house is h feet
40² = h² + (x + 5)²
⇒ 1600 = h² + (32 + 5)²
⇒ 1600 = h² + 1369
⇒ h² = 1600 - 1369
⇒ h² = 231
⇒ h = √231
⇒ h = 15.19 feet
Therefore, the distance far up the side of the house will the ladder reach now will be 15.2 feet.

Solve the following inequality. 21 ≤ -3(x − 4) < 30 A. 28 ≤ x < 37 B. -10 < x ≤ -3 C. -6 < x ≤ -3 D. -3 ≤ x < 6
Step-by-step explanation:
21 ≤ -3(x − 4) < 30
=> devided by (-3)
-7 ≥ x-4 > -10
=> added by 4
-3 ≥ x > -6
the result : -6 < x ≤ -3 (option C)

Answer:

Step-by-step explanation:
You're looking at a right triangle, with both legs being complementary forming 90
Since you know one measurement, 35, substract that from 90 and you get your missing angle.
90-35 = 55
Answer:
measure of the missing angle=55°
Step-by-step explanation:
Hi there!
We're given a right angle (as indicated by the red marking) being split into a 35° angle and another angle of unknown degree. Let's call the value of this angle x.
Because the given angle is 90° being split apart by the 35° angle and x, x+35° will equal to 90° (this is called parts whole postulate, where a whole (the 90° angle) is equal to the sum of its parts (the 35° angle and the x° angle))
so we can solve the equation as:
x+35°=90°
subtract 35 from both sides
x=55°
so the measure of the missing angle is 55°
Hope this helps! :)
A carpenter has two pieces of wood. He wants to find the density of each piece.
The first piece came from a birch tree. The piece of birch wood measures 2 meters by 4 meters by 3 meters and weighs (mass) 16 kilograms.
The second piece came from a cypress tree. The piece of cypress wood measures 3 meters by 5 meters by 2 meters and weighs (mass) 15.3 kilograms.
Which piece of wood has a greater density?
Answer:
The wood from the birch tree has a greater density than the wood that came from the cypress tree.
Step-by-step explanation:
Density formula: mass/volume
2 times 4 times 3=24 meters for the volume
Birch tree: 16/24 is the density
3 times 5 times 2=30 meters for the volume
Cypress tree: 15.3/30 is the density
If we convert the densities of each piece of wood to decimal it will be easier to determine which has a greater density.
So birch tree: 0.6 repeating is the density
Cypress tree: 0.51 is the density
Therefore the wood that came from the birch tree has a greater density than the wood that came from the cypress tree.
Hope I helped, have a nice day :)
