Answer:

3

Step-by-step explanation:

First, we need to understand what the problem is asking for.

The range of a function is the set of the y-coordinates of all the points of the function.

The domain of a function is the set of the x-coordinates of all the points of the function.

"A range value" means the same as "the y-coordinate of one point."

This problem is telling you that the y-coordinate of a point of function f(x) =  -2x + 6 is 0. Then it asks what its domain value is. It is asking you what is the x-coordinate of the point that has 0 as its y-coordinate.

Simply put, for function f(x) = -2x + 6, when y = 0, what is x?

f(x) = −2x + 6

-2x + 6 = -

-2x = -6

x = 3

Answer: 3

Given the formula a = s2 + 3b - c , find the value of a when s = 7, b = 13 and c = -24.
galben [10]

Answer:

a = 112

Step-by-step explanation:

a =s^{2} +3b-c

Given that,

s = 7

b = 13

c = (-24)

Let's solve for a now.

a =s^{2} +3b-c

a = 7^{2} +3*13-(-24)\\

a=49+39+24\\

a=88+24

a=112

Hope this helps you.

Let me know if you have any other questions :-)

Please help, I added a photo to show the question. I’m so confused and I need help, so if you could show work I’d really appreci
Mashutka [201]




Angle A = 30 and its complement would be 60. This is because both angles must equal 90 degrees, and 30 + 60 = 90. Also in the directions it states Angle A must be half of its complement. 30 is half of 60. Sorry I don’t have any work, I just did it in my head!

Any questions? Hope this helps!

A discount voucher offering 15% off is sued to pay a bill
mel-nik [20]

Answer:244.8

Step-by-step explanation:

15% of y=36.72

15/100 x y=36.72

15y/100=36.72

Cross multiply

15y=36.72 x100

15y=3672

Divide both sides by 15

15y/15=3672/15

y=244.8
