They are intersecting because if you take the equaton 3x+2

We are going to rearange both of these into slope intercept form.
First: 2y = -3x + 19 -> y = -1.5x + 9.5
Next: -5y = -4x + 10 -> y = .8x - 2
Finally: Because the two slopes are not the same, we know the lines are intersecting.

G(-4, -8) and H(-15, -3). What is the slope of GH?

Masteriza [31]

Answer:

G(x1,y1)= (-4,-8)

H(x2,y2)=(-15,-3)

Slope = (y2-y1)/(x2-x1)

=(-3-(-8))/ (-15-(-4))

= (-3+8)/(-15+4)

=5/-11

The answer is: x is choose your answer

katrin2010 [14]

Answer:

All real numbers

Let's find the critical points of the inequality.

−4x+7=17

−4x+7+−7=17+−7(Add -7 to both sides)

−4x=10

−4x−1=10−1

(Divide both sides by -1)

4x=−10

4x=−10(Solve Exponent)

log(4x)=log(−10)(Take log of both sides)

x*(log(4))=log(−10)

x=log(−10)log(4)

x=NaN

12x - 84 = 4x + 12. What does X equal?

Vesnalui [34]

Answer:

Step-by-step explanation:

To solve the problem, you have to leave the x alone,

To do so, you have to add 84 on each side

12x = 4x + 96

Then, subtract 4x on each side,

8x = 96

Then divide each side by 8, so

x = 12

Hope it helps!!
