Answer: a^4 b^2 x^4
Step-by-step explanation:
The exponent "product rule" tells us you, when multiplying two powers that have the same base, you can add the exponents.
so
a^3 b^2 x^4 a^1
a^3 and a^1 have the same base of a. So, add 3 + 1 for 4
Answer:A
Step-by-step explanation:
Answer:
x=-4
Step-by-step explanation:
1.4x +2.6x = -16

A direct variation is a proportional equation. Such as:
For every 3 cookies, linda gets 1 glass of milk. The equation for this is y=3x where y is the glasses and x is the cookies. this is a direct variation. It also has a linear line. Linear means straight. Rate of change and slope are the exact same thing. They are the value of 'm' in y=mx+b
