Answer:
a = (4/3)b
Step-by-step explanation:
The governing equation here has the form y = kx, where k is the constant of proportionality.
Let's rewrite that as a = kb, and then substitute -4 for a and -3 for b:
-4 = k(-3), or k = 4/3
Then a = (4/3)b

Apply the Keep Flip Change rule here
1/4 has been kept the same
The sign has been changed
The other fraction needs to be flipped
Thus, z = -2/7

Answer:
100√65 yds
Step-by-step explanation:
The Pythagorean Theorem is a^2+b^2=c^2. In this case a=700, b=400, and c is the unknown.
- 700^2+400^2=c^2
- 490000+160000=c^2
- 650000=c^2
- c=√650000
√650000=√(100^2•65)=100√65
When a decimal is multiplied to a power, it decreases exponentially. Therefore, y=3(0.2)^x does NOT represent exponential growth.
