Answer:
y = (3/8)x - 1.5
Step-by-step explanation:
Use the slope-intercept form y = mx + b. Substitute -1.5 for b, 4 for x and 0 for y. Then: 0 = m(4) - 1.5, or
4m = 1.5, or
The slope is m = 1.5/4, or m = 0.375, or m = 3/8.
Note that the x-intercept can be treated just like any other point: (4, 0)
Then the desired equation is y = (3/8)x - 1.5
Answer:
A) m < 7
Step-by-step explanation:
4m – 3(m + 1) – 4 < 0
Distribute the 3
4m -3m -3-4<0
m-7 <0
Add 7 to each side
m-7+7 <0+7
m<7
Answer:
126 degrees
Step-by-step explanation:
Triangle: y = 180 - (5x + 4x)
Straight angle: y = 180 - (4x + 30)
180 - (5x + 4x) = 180 - (4x + 30)
5x + 4x = 4x + 30
5x = 30
x = 6
Angle:
y = 180 - (5x + 4x)
y = 180 - 9x
y = 180 - 9(6)
y = 126
Answer:
900 students
Step-by-step explanation:
3/5 of 12,000 = 7,200 who drink coffee
1/8 x 7,200 = 900 who drink coffee with cream
