The answer is 9x+8. if you distripute the 2, you get 2x-6. if you distribute the 7, you get 7x+14. then you combine like terms ans get 9x+8

2(x-3)+7(x+2) now you time 2*x which you will get 2x, then you will times 2*-3 which is -6, now you times 7by x and you get 7x and times 7by 2 and you get 14 it should look like this

2x-6+7x+14 and then you add 2x+7x which is 9x then 14+-6 that is 8 it should look like this

9x+8

10. -3.8x - 5.9x = 223.1
Tema [17]

Answer:

-23

Step-by-step explanation: You have to combine like terms first:

-3.8x -5.9x                 =223.1

-9.7x                          = 223.1

Then divide om each side of the equation by -9.7.

-9.7x/-9.7                   = 223.1/-9.7

x                               =- 23

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation an
masha68 [24]

<span>Helena is correct in saying that the point-slope form will generate the equation. The point-slope form is written as:</span>

<span>
</span>

y-y₁ = m(x-x₁), where,

m = (y₂-y₁)/(x₂-x₁) is the slope of the line

(x₁,y₁) and (x₂,y₂) are the coordinates of the two points


On the other hand, the slope-intercept form is written as:


y = mx + b, where,

m is the slope of the line

b is the y-intercept


In this case, since only two points were given, the y-intercept of the line is not readily known. Thus, it is only through the point-slope form that the equation of the line can be determined. This is because it only requires the substitution of the x and y-coordinates of the points in the equation.

Enter the numerator that makes the equation true.
Gelneren [198K]

Answer:

1 3/4

Step-by-step explanation:

First write the equation in mixed fraction form as;

1 3/4 + 1 1/3 = 1 _/12 + 1 4/12 ⇒  7/4  + 4/3 = _ + 16/12

7/4  + 4/3 = _ + 16/12

37/12 = _ + 16/12

37/12 - 16/12 = _

= 21/ 12

= 1 9/12

= 1 3/4
