Answer:
81
Step-by-step explanation:
If a = 4, the exponent will be 
.
represents 3 being multiplied by itself 4 times.
= 3·3·3·3
=9·3·3
=27·3
=81
Your product is 81.
Answer:
Subtract the y's: 7 - 2 = 5
Subtract the x's in the same order: 6 - 4 = 2
slope = (difference in y)/(difference in x) = 5/2
Answer: 5/2
Answer:
A
Step-by-step explanation:
both b and c would make the trapezoid be in the quadrant below not to the right
Answer:
y = 4x
Step-by-step explanation:
When we say that x and y "vary directly", we mean that they have the relationship: y = kx, where k is a "constant of proportionality".
Here, we want to know what k is, so we plug 4 in for x and 16 in for y:
y = kx
16 = k * 4
k = 16/4 = 4
Thus, our equation is y = 4x.
