Answer:
The slope is 3 and the y-intercept is 2.
Step-by-step explanation:
Slope is 3/1, following the line up 3 and over 1. The line crosses the y-axis at (0,2), so the intercept is 2. The slope-intercept can then be written as y=3x+2.
3/4 = 0.75
each friend gets 0.75 of a bar
The two original functions are 4x+9y=7 and 4x-9y=9
To use the combination method, add all the values of the two equations together to cancel out one of the variables
4x+4x+9y-9y=7+9
8x=16
8x/8=16/8
x=2
4(2)+9y=7
8+9y=7
8-8+9y=7-8
9y=-1
y=-
Answer:
12
Step-by-step explanation:
24/x = x/6
x^2 =24*6 = 144
x=12
