A rectangle has a length of (3+4x) and a width of 12. 

A triangle has a base of 56 and a height of (2x-3). 

The area of the rectangle and triangle are equal. Find x.

• x=8

• x=15

• x=5

• x=12

What is the range of the part of the linear function shown.

The range is the set of all real numbers ​ ​ (a)   and ​ (b)   .

• greater than -4
• less than or equal to 8
• greater than or equal to -4
• less than 8
• greater than 3
• less than -5

The domain and range of part of a linear function are given:

x < 5

y > 2

A customer is ordering hats and T-shirts from an online store. Each hat costs $15, and each T-shirt costs $12. The customer receives free shipping if the amount of the order is over $150. Write an inequality that represents all possible combinations of hats, x, and T-shirts, y, in an order that qualifies for free shipping.
