120 + 125x = y

120 + 125(12) = y

120 + 1500 = y

The answer is $1620 for 12 months.

1. The linear equation y = 3x tells us that this line is going to be more vertical or horizontal? Explain.

More vertical.
y=x, where the slope is 1, is a line that forms a 45 degree angle with the positive part of the x axis. y=3x has a bigger slope, so it is going to rise 3 times faster than y=x so the line is more vertical
I hope that makes sense.

Y=7×2^t/30 what is the equation solved for t

CaHeK987 [17]

Answer:

Option C

Step-by-step explanation:

Given expression in the question is,

y = $7(2)^{\frac{t}{30}}$

To get the value of t,

$\frac{y}{7}=2^{\frac{t}{30}}$

Take the log on both the sides of the expression,

log( $\frac{y}{7}$ ) = $\text{log}[(2^{\frac{t}{30}})]$

log( $\frac{y}{7}$ ) = $\frac{t}{30}(\text{log2})$

t = $30(\frac{\text{log}\frac{y}{7}}{\text{log}2} )$

t = $30[\text{log}_2(\frac{y}{7})]$ [Since, $\frac{\text{loga}}{\text{logb}}=\text{log}_a(b)}$ ]

Therefore, Option C will be the answer.
