The weight limit of an elevator is 2,200 pounds. Michelle is solving an inequality to determine how many 40-pound boxes she can

safely bring in the elevator with her if she weighs 110 pounds and has a 10-pound push cart. When the solution to the inequality is graphed on a number line, which statements best describe the graph? Check all that apply. There is a closed circle on 55. There is a closed circle on 52. The solution set contains the point 51. The arrow points to the right. The arrow points to the left.

Solving the inequality for the number of boxes Michelle can take into the elevator:

2200 \geq 40 x + 120\\2080 \geq 40x\\x \leq 52

so the solution set is x<=52 with a closed circle on 52.

The following are the applicable choices from your  list (all at the same true):

"There is a closed circle on 52"

"The solution set contains the point 51"

"The arrow points to the left"

Answer: OK, the answer is 28.

Step-by-step explanation: Also there is no remainder for this division problem, you could have the remainder if the numbers are not the same as a multiplication problem, so did you get it?

Slope 1/3 passing through the points (-3,-4)
saw5 [17]

Answer:

y=1/3x-3

Step-by-step explanation:

use the eqation y-y1 = m(x-x1)

plug in slop as m and points as x and y

so now you have --> y-(-4)=1/3(x-(-3))

two negatives = a positive --> y+4=1/3(x+3)

distribute the 1/3 --> y+4= 1/3x + 1

subtract 4 from both sides --> y= 1/3x - 3

Solve the following system of equations algebraically:<br> 4x - 5y = 18<br> 3x – 2y = 10
fiasKO [112]

Answer:

D

Step-by-step explanation:

Given the 2 equations

4x - 5y = 18 → (1)

3x - 2y = 10 → (2)

Multiplying (1) by 3 and (2) by - 4, then adding will eliminate the x- term

12x - 15y = 54 → (3)

- 12x + 8y = - 40 → (4)

Add (3) and (4) term by term to eliminate x, that is

- 7y = 14 ( divide both sides by - 7 )

y = - 2

Substitute y = - 2 into either of the 2 equations and solve for x

Substituting into (1)

4x - 5(- 2) = 18

4x + 10 = 18 ( subtract 10 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

solution is (2, - 2 ) → D
