Answer:

x = 11.75

y = 11.5

Step-by-step explanation:

By Elimination Method:

   7x - 3y = 48    ---- (1)

-

<u>    2x + y = 35   ----</u>-   (2)

Multiply equation (1) by 2 and equation (2) by 7

   14x - 6y = 96

-

<u>    14x + 7y = 245      </u>

<u>      0   -13y = -149</u>

-13y = -149

y = -149/-13

y = 11.5

From equation (2); replace y with 12

2x + y = 35

2x + 11.5 = 35

2x = 35 - 11.5

2x = 23.5

x = 11.75

What is the slope-intercept form of the linear equation 4x + 2y = 24????
likoan [24]
Slope-intercept form of an equation is y = mx + b, where <em>m </em>is the slope and <em>b </em>is the y-intercept. 

To put this equation in the form of y = mx + b, we have to isolate the y. Here's how:
4x + 2y=24 \\ (4x + 2y)-4x=(24)-4x \\ 2y=-4x+24 \\ (2y)/2=(-4x+24)/2 \\ y= \frac{-4}{2}x + \frac{24}{2}   \\ y=-2x+12

In slope-intercept form, the equation is y = -2x + 12.

Hope this helps!

Y=-2x2+12x-26
Elis [28]

Answer:

y = 12x - 22

Step-by-step explanation:

If we first write the equation in vertex form and we identify it (I think you meant to simplify y) we get y = 12x - 22 as your answer!

The points -13 and 6 are plotted on a number line. What is the distance, in units, between the two points?
joja [24]

19 units

Use the absolute value to find the difference between the values. This ensures that no matter which way round the calculation is done the result is the same

| - 13 - 6 | = | - 19 | = 19

or

| 6 - (- 13) | = | 6 + 13 | = | 19 | = 19
