The problem gives you X, so replace X witht he given vaule and solve for y:


y = -0.1x^2 + 4X

X = 40

y = -0.1(40)^2 +4(40)

y = -0.1(1600) + 160

y = -160 + 160

y = 0

Plz help! I really need this!
Elan Coil [88]

Answer:

x=16

Step-by-step explanation:

the remaining angle for thw triangle is found by subtracting the already shown angles from 180 (the angle some of a triangle) which happens to be 96 to get 84 but now you need to subtract 84 from 180 to find the angle on the other side of line because lines have a total angle measurement of 180 but we already kbow what this get's us because it's 96 now we devide 96 by 6 to get 16 our answer.

What is the slope of the line y=5?
IceJOKER [234]

Answer:

0

Step-by-step explanation:

if you slightly change the equation to better fit standard form (without actually changing its meaning) you get

y = 0x + 5

which means the slope is 0

Also, a shortcut:

<h2><u>Horizontal lines always have a 0 slope while vertical lines have an undefined slope</u></h2>
