If ac =x+3 and db=3x-19, find ac
AveGali [126]
We need some sort of diagram to see what they are. Is there any way to say that ac = db? Either equal angles or equal lines. 
x + 3 = 3x - 19 Add 19
x + 3 + 19 = 3x Subtract x
21 = 2x
x = 21 / 2
x = 10.5

ac = 10.5 + 3
x = 13.5

What is the equation of the graphed line written in
Andrew [12]

<u>Given</u>:

Given that the graph of the linear equation.

We need to determine the equation of the graph.

<u>Slope</u>:

The slope of the equation can be determined using the formula,

m=\frac{y_2-y_1}{x_2-x_1}

Let us substitute the coordinates (2,0) and (0,-4) in the above formula, we get;

m=\frac{-4-0}{0-2}

m=\frac{-4}{-2}

m=2

Thus, the slope of the equation is 2.

<u>y - intercept:</u>

The y - intercept of the equation is the value of y when x = 0.

Hence, from the graph, it is obvious that when x = 0, the value of y is -4.

Therefore, the value of the y - intercept is b = -4.

<u>Equation of the line:</u>

The equation of the line can be determined using the formula,

y=mx+b

Substituting the values, we have;

y=2x-4

Subtracting both sides by 2x, we have;

-2x+y=-4

Dividing both sides by -1, we get;

2x-y=4

Thus, the equation of the line is 2x-y=4

Hence, Option B is the correct answer.

2 1.3.1 Study: Multiplying Binomials Drag the tiles to the blanks. Distribute. - 4(x - 2) =​
ehidna [41]

Answer:

I am not entirely sure what you are asking here but if I am right then the answer is -4(x-2) = 8 - 4x

Step-by-step explanation:

Multiplying binomials all you have to do is distribute the 4

Multiply  -4 by x to get: -4x

Muliply -4 by -2 to get: 8 (Because two negatives make a positive)

Now you have -4x + 8

Rewrite so it flows better and the answer is:

8 - 4x
