This can be visualized as follows:

Since AB=7, then BC = 7 and AC=AB+BC = 14

Answer: BC = 7, and AC=!4

HELP ASAP!!!<br> Find the slope of this equation: <br> 6x+6=−4y
Dmitriy789 [7]

Answer:

the slope is -3/2

Step-by-step explanation:

We need to get the equation in the form

y = mx +b where m is the slope and b is the y intercept

6x+6 = -4y

Divide by -4

-6x/-4 +6/-4 = -4y/-4

-3/2 x -3/2 = y

The slope is -3/2 and the y intercept is -3/2
