Consider this equation: {x-9 - 2x+2 = 1 Which is an equivalent equation after combining like terms? 8 X-11=1 3 -= -4 X-71 3 8 -7

grandymaker [24]

Answer:

B. -4/3x - 7 = 1

Step-by-step explanation:

2/3x - 9 - 2x + 2 = 1
2/3x - 2x - 7 = 1
2/3x - 6/3x - 7 = 1
-4/3x - 7 = 1

Correct option is B

Enter an equation in point-slope form for the line. (6,8) and (7,1) is on the line. The equation of the line in point slope form

Yuri [45]

Answer:

$y - 8 = -7(x - 6)$ or $y - 1 = -7(x - 7)$

Step-by-step explanation:

The point-slope form equation is $y - b = m(x - a)$ , where,

(a, b) = a point on the line.

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

Given the two points, (6, 8) and (7, 1), find the slope of the line:

$m = \frac{1 - 8}{7 - 6}$

$m = \frac{-7}{1}$

$m = -7$

There are two possible point-slope equation we can come up with using each points on the line given.

Using the point (6, 8) and m = -7,

Substitute m = -7, a = 6, and b = 8 into $y - b = m(x - a)$

$y - 8 = -7(x - 6)$

Using the point (7, 1) and m = -7,

Substitute m = -7, a = 7, and b = 1 into $y - b = m(x - a)$

$y - 1 = -7(x - 7)$

3(x+2) = 2(2x+7) — solve for x and please explain

Sedbober [7]

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

3x + 6 = 4x + 14 (On the left side we distribute 3 through parenthesis and on the right side we do the same with 2)

3x - 4x = 14 - 6 (Here we move 4x from the right to the left side and it changes its sign. We do the same with 6)

-x = 8

x = - 8
