Joan received $17 and 94 cents ($17.94)
$14.20 + $7.86= $22.06 (her total)
$20+$20= $40 (how much she paid with)
$40- $22.06= $17.94
Step-by-step explanation:
The graphs intersect each other at points (-3, 2) and (1, 6).
The x-values of these points are -3 and 1.
Hence the 2 solutions are x = -3 and x = 1.
Answer:
Step-by-step explanation:
x - 2y = 8
Write this in y = mx +b form
- 2y = -x + 8
Divide the equation by (-2)

Slope = 1/2
The slope of the perpendicular line = -1/m

m = -2 , ( -2 , 5)
Equation: y = mx +b
Plug in m = -2 ,x = -2 and y =5
5 = (-2)*(-2) + b
5 = 4 + b
5 - 4 = b
b = 1
Equation of the line:
y = mx +b
y = -2x + 1
Answer:
Step-by-step explanation:
The ratio of the sides is the same as the one-to-one measure of the similar figures. To get to the ratio of their areas, square the one-to-one values. To get to the ratio of their volumes, cube the one-to-one values.
If the one-to-one is 3:7, then the ratio of their volumes is
3³:7³ which is 27:343
