Answer:

x = -4

Step-by-step explanation:

2x + 4(2x+7) = 3(2x+4)

distributive property first

2x + 8x + 28 = 6x + 12

now combine like terms

10x + 28 = 6x + 12

now move the +28 over to the other side by subtraction

10x = 6x -16

move the 6x over by subtraction

4x = -16

divide by 4

x = -4

Find equation of a line with the given slope that passes through the given point. Write the equation in the form Ax + By = C.
attashe74 [19]

Answer:

5x + y = -28

Step-by-step explanation:

Hi there!

We're given that a line has a slope of -5 and contains the point (-4, -8)

We want to write the equation of this line in standard form

Standard form is given as ax+by=c, where a, b, and c are free integer coefficients, but a and b cannot be zero, and a cannot be negative

Before we write the equation in standard form however, we need to write it in slope-intercept form, which is y=mx+b, where m is the slope & b is the y intercept

As we are already given the slope, we can immediately plug that in for m in y=mx+b

y=-5x+b

Now to find b:

As the equation passes through the point (-4, -8), we can use its values to help solve for b

Substitute -4 as x and -8 as y:

-8 = -5(-4) + b

Multiply

-8 = 20 + b

Subtract 20 from both sides

-8 = 20 + b

-20  -20

__________

-28 = b

substitute -28 as b

y = -5x - 28

We found the equation in slope-intercept form, but remember, we want it in standard form

In standard form, both x and y are on the same side; so, let's move 5x to the other side; to do this, we need to add 5x to both sides

y = -5x - 28

+5x +5x

_________

5x + y = -28

Hope this helps!

How do you solve 11+6(x+5)=42/ 9
kvasek [131]
First do the solving you CAN do

17(x+5)=4.67

then, get x by itself my moving 5 and 17 over

(17(x+5)/17=4.67/17

x+5=.<span>2745

x=-</span><span>4.725

and there's the answer!</span>
