7(7a-9)>84

first multiple out to get rid of the parentheses

49a - 63 > 84

add 63 to both sides

49a > 147

Divide by 49 and flip the sign because when you divide a inequality you have to flip the sign

a < 3

A line passes through the point (–2, 7) and has a slope of –5.
ICE Princess25 [194]

Answer:

B

Step-by-step explanation:

Let's create an equation in point-slope form, which is: y-y_1=m(x-x_1), where (x_1,y_1) is the point and m is the slope.

Here, our point is (-2, 7) and our slope is m = -5 so plug these in:

y -7=-5*(x-(-2))

y -7=-5*(x+2)

Now, if (a, 2) lies on this line, then it should satisfy the equation. So plug in a for x and 2 for y:

2 - 7 = -5(a + 2)

-5 = -5(a + 2)

Divide by -5:

1 = a + 2

Subtract 2 from both sides:

a = -1

Thus, the answer is B.

Hope this helps!

Given that p is an integer, q = -12 and the quotient of p/q is -3, find p
sergejj [24]
I think it’s p=36 because you have to do the opposite on both sides..

So..
q=-12
P/-12=-3
+12 *12
P=36
