3 times 2x = 6x

3 times 2 = 6

now u have

6x+6+(1)x+5=-10

if the letter is alone there is a 1 there.

6x+1x=7x

6+5= 11

7x+11 = -10

flip 11 to -11

7x = -10-11= -21

7x=-21

(forgot this part)

7 divide by 21 is 3

x= -3

Hope this helps

Answer:

Part a)

We need to find the equation of a straight line passing through two given points in slope-intercept form

Part b)

The information given; we are given two points where the line passes through; (0, -4) and (-2, 2)

Part c)

We shall first determine the slope of the line using the formula;

change in y/change in x. Next, we determine the value of the y-intercept using the general form of the equation of a straight line in slope-intercept form; y = mx+c

Part d)

The slope of the line is calculated as;

(2--4)/(-2-0) =6/-2 = -3

The equation of the line in slope-intercept form becomes;

y = -3x +c

We use the point (0, -4) to determine the value of c;

-4 = -3(0)+c

c = -4

Part e)

Final solution thus becomes;

y=-3x-4

5x + 9x if x =3 solve this expressioon

RSB [31]

The answer is actually 42. Not 20.

You replace each x with 3

5(3)+9(3)

That 3 right next to the five means you multiply not add.

15+27=42

Brainliest my answer if it helps you out?
