Add two like terms: 16x+(-9x)=7x
Add 15 to both sides: 7x=28
Divide 7 on both sides: x=4
Answer:
The first graph(Left)
Step-by-step explanation:
Because in this form 1/2 is the slope and -5 is the y intercept.
<span>A) The constant is 7.5. FALSE. 7.5 is a coefficient, not a constant.
</span><span>B) The coefficients are 7.5 and -9. FALSE. The coefficients are 7.5, -1/9 and 2. 50, being a constant, could be regarded as a coefficient in this case.
</span><span>C) The variables are x and y. FALSE. There are three variables: x, y and z.
</span><span>D) The like terms are 7.5y and 2y. TRUE. The variable (y) is the same in each term.</span><span>
