Answer:
50
Step-by-step explanation:
Use pythagoreom theorem to determine the length of the hypotenuse:
a² + b² = c²
- assign side a to 30 and side b to 40
30² + 40² = c²
90 + 160 = c²
250 = c²
Now square root both sides to isolate side c:
√250 = √c²
50 = c
side c = 50
Answer:
D. y=-3x+8
Step-by-step explanation:
first, get the 12x on the other side of the equation
12x+4y-12x=32-12x
4y=-12x+32
divide the equation by four
y=-3x+8
Hope this helps!
Four times fifteen plus twenty in parentheses
idk if its correct though <span />
Answer:
f(3) = -13
Step-by-step explanation:
To answer this question, we plug 3 into the place of x, so the equation now looks like;
f(3) = -5(3) + 2
We simply apply PEMDAS by multiplying -5 and 3, then adding 2 to get;
f(3) = -13
