Suppose it cost you $78.48 for a 9-month subscription to a streaming video service. Write a proportion that you can use to find the cost in dollars for a 12-month subscription. Then solve.
Answer:
78.48÷9×12=cost
104.64
Step-by-step explanation:
amount divide by 9 months equals cost per month
take that by 12 to give 12 months sub

Find the axis of symmetry for this parabola:
y = -4x2 - 8x - 7
Answer:
Step-by-step explanation:
If we want to find the axis of symmetry of the parabola of [tex]y=-4x^{2} -8x-7,[/tex] we would use the formula of [tex]-\frac{b}{2(a)}[/tex] to find it.
b=-8
a=-4
so the formula would look like this [tex]-\frac{-8}{2(-4)}[/tex], simplify it >>>[tex]-\frac{-8}{-8}[/tex] which is -1
So -1 would be the axis of symmetry

Write an equation in slope-intercept form for the line that passes through (−2, 3) and is parallel to
the line with the equation 3x + 2y = 6.
y= (-3x+6)2
For parallel lines, slopes are the same,
y = mx + c
Substitute the values,
3 = (-3/2)(-2) + c
3=3 + c,
c = 0
Thus, the equation is y= -3/2x

the function f(x)=-4x+9 has a range given by {1, -3, -7, -15, -19, -23} select the domain values of the function from the list. complete the explanation for how you arrived at your answer. btw this isn’t actually a test it’s assigned as hw but please help
Let's see what to do buddy....
_________________________________
Remember from now on ,
rang = output
and also Remember ,
output = y = f(x)
So : range = f(x)
So we must put the range number instead of f(x) and solve for x.
Let's do it...
=======================================
[tex]f(x) = 1[/tex]
[tex] - 4x + 9 = 1[/tex]
Both sides minus 9
[tex] - 4x = 1 - 9[/tex]
[tex] - 4x = - 8[/tex]
Negatives simplified
[tex]4x = 8[/tex]
Divided both sides by 4
[tex]x = \frac{8}{4} \\ [/tex]
[tex]x = 2[/tex]
_________________________________
[tex]f(x) = - 3[/tex]
[tex] - 4x + 9 = - 3[/tex]
[tex] - 4x = - 3 - 9[/tex]
[tex] - 4x = - 12[/tex]
[tex]4x = 12[/tex]
[tex]x = \frac{12}{4} \\ [/tex]
[tex]x = 3[/tex]
_________________________________
[tex]f(x) = - 7[/tex]
[tex] - 4x + 9 = - 7[/tex]
[tex] - 4x = - 7 - 9[/tex]
[tex] - 4x = - 16[/tex]
[tex]4x = 16[/tex]
[tex]x = \frac{16}{4} \\ [/tex]
[tex]x = 4[/tex]
_________________________________
[tex]f(x) = - 15[/tex]
[tex] - 4x + 9 = - 15[/tex]
[tex] - 4x = - 15 - 9[/tex]
[tex] - 4x = - 24[/tex]
[tex]4x = 24[/tex]
[tex]x = \frac{24}{4} \\ [/tex]
[tex]x = 6[/tex]
_________________________________
[tex]f(x) = - 19[/tex]
[tex] - 4x + 9 = - 19[/tex]
[tex] - 4x = - 19 - 9[/tex]
[tex] - 4x = - 28[/tex]
[tex]4x = 28[/tex]
[tex]x = \frac{28}{4} \\ [/tex]
[tex]x = 7[/tex]
_________________________________
[tex]f(x) = - 23[/tex]
[tex] - 4x + 9 = - 23[/tex]
[tex] - 4x = - 23 - 9[/tex]
[tex] - 4x = - 32[/tex]
[tex]4x = 32[/tex]
[tex]x = \frac{32}{4} \\ [/tex]
[tex]x = 8[/tex]
=======================================
So the domain values are :
x = { 2 , 3 , 4 , 6 , 7 , 8 }

Answer:
The answer is 30 degrees
Step-by-step explanation:
the total of all three angles in a triangle add up to 180.
50+100= 150
so,
180-150= 30
x= 30 degrees

Parallel drainage pipes are connected with a third pipe. The connector pipe makes a 65 degree angle with a pipe as shown. What is the measure of the angle it makes with the pipe on the other side of the road. Explain.
Use the figure below to solve for X.
x=45, we know 2x is 90 because it is a right angle, so we can divide 90 by two, to get 45. Now to substitute, 90+55+(45-10) = 180, therefore, this answer would make logical sense.

Please consider Brainliest :)
62% of 324 is 200 Round to the nearest hundredth.
What is percent?In mathematics,a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".
Now the given number is 324.
Given percentage is 62% or 0.62.
So for 62% of 324 we have,
62% of 324 = 0.62 x 324
or, 62% of 324 = 200.88
