Answer:
x = -6
Step-by-step explanation:
-5(x + 3) = 15
Distribute the -5
-5x -15 =15
Add 15 to each side
-5x-15+15 =15+15
-5x = 30
Divide each side by -5
-5x/-5 = 30/-5
x =-6
Answer:
Every ordered pair within this region will satisfy the inequality y ≥ x. Incorrect. The boundary line here is y = x, and the correct region is shaded, but remember that a dotted line is used for < and >. The inequality you are graphing is y ≥ x, so the boundary line should be solid.
Answer:
No. Lauren cannot buy the shirt. It costs $48 after the discount.
Step-by-step explanation:
Shirt Cost: $80
Money: $35
Discount: 40%
First, find the amount of the discount by finding 40% of the price. 40% is equal to 0.40 (or 40 divided by 100).
40% of $80 = 0.40 x 80 = $32
Since it's a discount, the final price is the original price minus the discount.
$80 - $32 = $48
So, after a 40% discount, the price is still $48. Lauren only has $35, so it will still be too expensive!
