First question : x=8 and y= -2
and once again, i dont know how t make a table
The answer is x=14.......
Answer:
y = -1/4x - 1
Step-by-step explanation:
4x - 1
Change 4x to -1/4 to make the slope perpendicular
Then put (4, -2) on x and y to find b
-2 = -1/4(4) + b
-2 = -1 + b
-2 + 1 = -1
b is -1
So your final answer in slope intercept form is y = -1/4x - 1
Answer:

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
f(x) = 8x + 5
g(x) = 7x - 2
<u>Step 2: Find f(g(4))</u>
- Substitute in <em>x</em> [Function g(x)]: g(4) = 7(4) - 2
- Multiply: g(4) = 28 - 2
- Subtract: g(4) = 26
- Substitute in function value [Function f(x)]: f(g(4)) = 8(26) + 5
- Multiply: f(g(4)) = 208 + 5
- Add: f(g(4)) = 213
Answer:
-9
Step-by-step explanation:
9=b-2b
9=-b
divide both sides by -
b=-9
