Kadesha is simplifying the expression below.
-(x-3) - 2(x-1)
she lists the steps that she uses to simplify the expression as follows:
step 1: distribute –1 through (1-3), and distribute-2 through (x-1).
step 2: rewrite the expression as -x-3-2x-2.
step 3: combine - and -2x, and combine -3 and -2.
step 4: the simplified expression is -3x-5.
in which step did kadesha make the first error?
she made the first error in step 1 because only -2 should be distributed through the parentheses.
she made the first error in step 2 because step 2 should be -x+3-2x+2.
she made the first error in step 3 because -x and -2x cannot be combined.
she made the first error in step 4 because the simplified expression is -x-5.

step-by-step explanation:

if you're trying to figure out how much each ounce cost it would be 0.20

cents each ounce

answer:

given the linear inequality :

add 2y to both sides we get;

simplify:

add 12 to both sides of an equation;

simplify:

divide both sides by 2 we get;

or

the related equation for the inequality equation [1] is;

y-intercepts defined as the graph crosses the y-axis.

substitute x =0 in [2] to solve for y;

y = 6

x-intercepts defined as the graph crosses the x-axis.

substitute value y = 0 to solve for x;

subtract 6 from both sides we get

multiply both sides by 2 we get;

or

x = -12

now, plot these point (0, 6) and (-12, 0) on graph as shown below and shade the graph below the solid line.
