A) 42x-12
6*7=42. 6*2=12
b) 21y
11+4+6=21
Answer:
? = -1 1/4 (Negetive one and one fourth)
Step-by-step explanation:
Use this calculator to solve those difficult Algebra problems!

<span>when the altitude is </span>drawn from the vertex of the right angle<span> of a right triangle to its hypotenuse, the altitude equals the product</span> of the two segments of the hypotenuse<span>.
(w+9)</span>²=8*18=144
w+9=12 or w+9=-12
w=3 (discard the negative number)
use the same method, z=√(9*11)=3√11
next, you can use the Pythagorean theorem to find x and y.
x=√(9²+99)=√180=6√5
y=√(11²+99)=√220=2√55
Answer:
3
Step-by-step explanation:
To find the rate of change we: divide the change in y (output) by the change in x (input).
A = (-3 - 0) / (0 - 1) = -3 / -1 = 3
