Set Abe as x
set Bella as y
set Carlos as z
<span>Bella has earned 10 less credits than Abe
y=x-10
</span><span>Carlos has earned two less than double the number of Abe’s credits
</span><span>z=2x-2
</span><span>Altogether, they have earned a total of 136 credits
</span><span>x+y+z=136
replace y with x-10
replace z with 2x-2
x+(x-10)+(2x-2)=136
solve for x
4x-12=136
4x=148
x=37
We now know Abe earned 37 credits
To find how much Bella earned plug in 37 for y=x-10
y=27
To find how much Carlos earned plug in 37 for z=2x-2
z=72
Therefore,
Abe earned 37 credits
Bela earned 27 credits
Carlos earned 72 credits

Answer:
Parallel: y=-4x-1
Perpendicular: y=-4x+13/2
Step-by-step explanation:
For the equation y=-4x-41, the slope is -4. Writing a line related to this equation has two options:
- If the line will be parallel to it then this is the slope of the new line as well. Use the point-slope form to write the equation, then simplify and convert into the slope intercept form.
(y-7)=-4(x--2)
y-7=-4x-8
y=-4x-1
- If the line will be perpendicular to it then the slope is the negative reciprocal of the previous slope. It is 1/4.
(y-7)=1/4(x--2)
y-7=1/4x-1/2
y=-4x+13/2
1/4 i think to be honest im not really good at math hope i helped
