Which x value makes this equation true? Explain how you can tell

MrMuchimi

Answer:

b) x = 4

Explanation:

$2x^2 - x + 10 = 38$

collect variables

$2x^2 - x + 10 - 38 = 0$

simplify

$2x^2 - x - 28 = 0$

breakdown

$2x^2 -8x + 7x - 28 = 0$

factor out

$2x(x - 4) + 7(x - 4) = 0$

collect into groups

$(2x + 7)(x - 4) = 0$

set to zero

$2x + 7 = 0, x - 4 = 0$

relocate variable

$2x = -7, x = 4$

final solutions

$x = -3.5, x = 4$

Write an equation in point slope form of the line that passes through the point -4, 5 and has the slope of one.

Gnesinka [82]

Answer:

y - 5 = x + 4

Step-by-step explanation:

Use point slope form, y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line

Plug in the given point and slope:

y - y1 = m(x - x1)

y - 5 = 1(x + 4)

Simplify:

y - 5 = x + 4

So, the point slope form of the line is y - 5 = x + 4
