Answer:
I assume you want the equation for the line in y=mx+b form, if not, you can just transfer this form to standard or intercept. y=(-3/4)x+2.5
Step-by-step explanation:
Since you have the slope and a point, plug in the points to the equation y=9-3/4)x+b to get 4=(-3/4)(-2)+b and solve.
Answer:
78.5 inch²
Step-by-step explanation:
Given
diameter (d) = 10 inches
radius (r) = 10 / 2 = 5 inches
Area of circle
= πr²
= 3.14 * ( 5)²
= 3.14 * 25
= 78.5 inch²
I believe your answer should be C > -5/4
(12,-24)
x intercept is 12 & y intercept is -24
Set up 2 equations.(x = number of people in first class, y = tourist class)
30x + 25y = 1360
x + y = 52
You have 2 equations and 2 unknown. You can solve them.
I like to use the substitution method
Because y = 52 - x
Then 30x + 25(52 - x) = 1360, solve for x.
30x + 1300 - 25x = 1360
5x = 60
x = 12
Use the x to solve y
30(12) + 25y = 1360
360 + 25y = 1360
25y = 1000
y = 40
