Answer:
![f(-9)=\frac{131}{2}](https://tex.z-dn.net/?f=f%28-9%29%3D%5Cfrac%7B131%7D%7B2%7D)
Step-by-step explanation:
In order to evaluate a function at a given x-value, plug in that value into the actual function
![f(x)=-\frac{x}{2} -7x-2\\\\f(-9)=-\frac{9}{2} -7(-9)-2\\\\f(-9) = \frac{131}{2}](https://tex.z-dn.net/?f=f%28x%29%3D-%5Cfrac%7Bx%7D%7B2%7D%20-7x-2%5C%5C%5C%5Cf%28-9%29%3D-%5Cfrac%7B9%7D%7B2%7D%20-7%28-9%29-2%5C%5C%5C%5Cf%28-9%29%20%3D%20%5Cfrac%7B131%7D%7B2%7D)
Answer:
A. y = -3/2x + 1
B. y = -5/3x + 10
C. y = -x + 6/5
Step-by-step explanation:
A. You just have to isolate the y so divide by 4: y = -3/2x + 1
B. 3y = -5x + 30
Divide by 3: y = -5/3x + 10
C. -5x + 6 = 5y
Divide by 5: -1x + 6/5 = y OR y = -x + 6/5
Answer:
so the answer is 95°
Step-by-step explanation:
The two angles on a line add up to 180° or are supplementary, so we can find the inside angle x by doing 180-150=30°. Now that we know inside x is 30, if we add 30+65, we get 95, and 180-95=85°. Then to find angle xzw, just do 180-85 to get 95°.
