Which expression makes the equation true for all values of x ? 16x-16=4(?)

Vinil7 [7]

ANSWER

4x-4

EXPLANATION

The given equation is

16x-16=4(---?---)

To find the expression that makes the equation true, we need to factor 4 from 16x-16.

This implies that,

$16x - 16 = 4(4x - 4)$

Hence the expression that makes the statement true is

$4x - 4$

The correct answer is option A.

100 POINTS+BRAINLIEST 8TH GRADE MATH PT 5: WRITE THE EQUATION OF A LINE- this one was strange because the slope is supposed to b

Finger [1]

Answer:

$\textsf{b.} \quad 3x+5y=2$

Step-by-step explanation:

Define the given points:

$\textsf{let}\:(x_1,y_1)=(4,-2)$

$\textsf{let}\:(x_2,y_2)=(-1,1)$

Use the slope formula to determine the slope of the line:

$\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1-(-2)}{-1-4}=\dfrac{1+2}{-1-4}=-\dfrac{3}{5}$

Use the point-slope formula to determine the equation of the line.

$\implies y-y_1=m(x-x_1)$

Substitute the found slope and point (4, -2):

$\implies y-(-2)=-\dfrac{3}{5}(x-4)$

$\implies y+2=-\dfrac{3}{5}(x-4)$

Multiply both sides by 5:

$\implies 5(y+2)=-3(x-4)$

Expand the brackets:

$\implies 5y+10=-3x+12$

Add 3x to both sides:

$\implies 5y+10+3x=-3x+12+3x$

$\implies 3x+5y+10=12$

Subtract 10 from both sides:

$\implies 3x+5y+10-10=12-10$

$\implies 3x+5y=2$
