Answer:he needs no more cups of water
Step-by-step explanation:
Answer:
a). y = 0.25x + 15
b). x = 480 cups
Step-by-step explanation:
(a). Let the equation of the linear function passing through a point (x', y') is,
y - y' = m(x - x')
'm' = slope of the line
b = y-intercept
Two points lying on the linear function will be (200, 65) and (250, 77.5).
Slope of the line 'm' = 
m = 
= 
= 0.25
Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,
y - 65 = 0.25(x - 200)
y - 65 = 0.25x - 50
y = 0.25x + 15
(b). For y = $135 we have to calculate the number of cups of coffee produced.
135 = 0.25x + 15
0.25x = 135 - 15
0.25x = 120
x = 480 cups
Therefore, 480 cups of coffee will be produced.
Answer:
2.75 miles in 1 hour
Step-by-step explanation:
Answer:
7
Step-by-step explanation:
means x*x = 49
x * x = 49
x= 7

Hope this helps :)
Have a great day!
#1
(-2,0)(0,1)
slope = (1-0)/(0+2) = 1/2
passing point (3,5)
y = mx + b
5 = 1/2(3) + b
5 = 3/2 + b
5 - 3/2 = b
7/2 = b or b = 7/2
equation
y = 1/2x + 7/2
