L 4.4.2 Test (CST): Systems of Equations and Inequalities Question 23 of 25
Which of these shows the result of using the first equation to substitute for y
in the second equation, then combining like terms?
y= 2x
2x + 3y = 16
A. 4x= 16
O B. 8x = 16
C. 5x = 16
O D. 5y= 16

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

a

step-by-step explanation:

i believe a. 12x≥120 is the answer

all you have to do is multiply them both to see how many out comes you can put:

3 x 2 = 6

you can make 6 diferent combinations of crusts and toppings.
