David made a class banner out of a large rectangular piece of paper. He cut a
Irina18 [472]

Answer:

100 in²

Step-by-step explanation:

The area of the banner is equal to the area of the initial rectangle minus the area of the cutout triangle.

The rectangle has a height of 8 inches and width of 14 inches, so its area is:

A = (8 in) (14 in) = 112 in²

The triangle has a base of 8 inches and a height of 3 inches, so its area is:

A = ½ (8 in) (3 in) = 12 in²

So the area of the banner is 112 in² − 12 in² = 100 in².

Arlene buys a phone case and charging cord for 15% off. The original cost of the phone case is $18. Her total discount is $4.20.
mel-nik [20]

Answer: $10

Step-by-step explanation:

Assume the price of the phone case is x.

Assume the price of the charging cord is y.

Discounted price for phone case :  15% * x

= 0.15x

Discounted price for charging cord = 0.15y

Expression is therefore:

0.15x + 0.15y = 4.20

0.15 * 18 + 0.15y = 4.20

2.7 + 0.15y = 4.20

0.15y = 4.2 - 2.7

y = 1.5/0.15

y = $10

Determine which graph represents a reflection across the x-axis of f(x) = 3(1.5)x.
vivado [14]

The reflection is written as:

g(x) = -3*(1.5)^x

And the graph can be seen below.

<h3>How to get the graph of the reflection?</h3>

Here we have the function:

f(x) = 3*(1.5)^x

A reflection across the x-axis is given by:

g(x) = -f(x).

Then, replacing the function f(x) by the actual equation:

g(x) = -3*(1.5)^x

The graph of the function g(x) can be seen below:
