Answer:
24:40:56
Step-by-step explanation:
3+5+7=15
120/15=8 1 Ratio is 8
3x8=24
5x8=40
7X8=56
i dont know if its the easiest method
Ok, so first, the y-intercept is always the last number. So the y-intercept for the first equation would be -1, and for the second equation, 4.
Put a dot, or a point on -1and 4 on the graph.
The slope is always he number with an x.
So the slope would be 3 for the first equation.
And the slope for the 2nd equation would be -2.
If the slope doesn't have a denominator, put 1 as it's denominator.
So, 3x would turn into
And -2x would turn into
So the rule for slope is:
So, go to your -1, and go up 3 and 1 right. Keep doing that until you reach the end of the graph.
Now, go to your -4, go down 2 and go left 1. Keep doing that until you reach the end of the graph.
Now, draw the lines.
I'll show on piece of paper how to do this if you dont get the explanation I gave.
Answer: =125.6

Answer:$5.33
Step-by-step explanation:
2/3 is equal to 0.6666666667
If u multiply that by 15.99 you get 10.66 then you subtract that from 15.99 and you get your answer
F(x)=1/3-1/21x
0=1/3-1/21x multiply both side by 21
0=7-x
X=7
