X and y-intercept of y=X-5
aksik [14]
The x-intercept is when y = 0
y = x - 5 → 0 = x - 5 → x = 5

The y-intercept is when x = 0
y = x - 5 → y = 0 - 5 → y = - 5

Answer: x-intercept is (5, 0), y-intercept is (0, -5)

Henry wants to paint the ceilings and the walls of his living room. One gallon of paint covers 450 ft squared. The rooms is 24 f
Mamont248 [21]
If you would like to know how many gallons of paint will Henry need to paint his living room, you can calculate this using the following steps:

the ceiling: 24 ft * 18 ft = 432 ft squared
walls: 2 * 24 ft * 9 ft + 2 * 18 ft * 9 ft = 2 * 24 * 9 + 2 * 18 * 9 = 432 + 324 = 756 ft squared

432 ft squared + 756 ft squared = 1188 ft squared

1 gallon of paint ... 450 ft squared
x gallons of paint = ? ... 1188 ft squared

1 * 1188 = 450 * x
1188 = 450 * x    /450
x = 1188 / 450
x = 2.64 gallons of paint

The correct result would be 2.64 gallons of paint.
