Answer:

$x= \frac{y-4}{7}$

Step-by-step explanation:

$y=7x+4$

Subtract 4 from both sides.

$y-4=7x+4-4$

$y-4=7x$

Divide by 7 on both sides.

$\frac{y-4}{7} =7x/7$

$x= \frac{y-4}{7}$

Answer: See explanation

Step-by-step explanation:

Interest = PRT

Principal = $100

Rate = 10%

Time = 1 year

Interest = PRT = (100 × 10% × 1)

= 100 × 0.1 × 1

Interest = $10

Amount = Principal + Interest

= $100 + $10

= $110

What is the question of the line that passes through the point (-2,-2) and has a slope of 4. Plz someone answer

Studentka2010 [4]

Answer:y=4x+6

Step-by-step explanation:

We have the information that the slope is 4 and the line goes through the point (-2,-2). With this information, we can make a linear equation in a point slope form ( $y - y_{1}= m * (x - x_{1})$ , so the equation would be $y+2=4(x+2)$ , or simplified, $y+2=4x+8.$ in order to solve for y (to make it a slope-intercept equation), we must subtract 2 from both sides. This gives us the equation y=4x+6. Hope this helps!
