I just substituted the value given from x and solved for y. I hope that is what the question is asking for.
Hope this helps :)
Answer:
-20
Step-by-step explanation:
Replace X by 3
f(3) = -2(3)^2+ (3)-5 = -20
Answer:
The answer to your question is:
Step-by-step explanation:
m ∠ 1 = 27°
m ∠ 1 and m ∠ 2 are supplementary
m ∠ 1 + m ∠ 2 = 180°
27° + m ∠2 = 180°
m ∠ 2 = 180° - 27°
m = 2 = 153°
Lines are described by equations of the form y = mx + b
The fast way of finding 'b' is to look for a place where x = 0 and plug in the x and y values into this equation. In the case of this line, when x = 0, y = 5:
5 = m(0) + b
5 = 0 + b
5 = b
To get the slope, 'm', we need to pick two points and divide the difference of their y values by the difference of their x values. Pick points where the line falls on the grid. The one we just used, (0,5), works well. So does (2,1).
Plug into the equation m = (y2-y1)/(x2-x1) to get m = (1-5)/(2-0) = -4/2 = -2
Our equation is y = -2x + 5
