Answer:
x=5
Step-by-step explanation:
9-x-x=-1
Combine like terms.
9-2x=-1
Subtract 9 from both sides.
-2x=-10
Divide both sides by -2.
x=5
I belieeeeve the first one is 35 and the second one is success??
Hi! Your answer is y = x + 4
Please see an explanation for a better and clear understanding to your problem!
Any questions about my answer and explanation can be asked through comments! :)
Step-by-step explanation:
Here are the reasons why it's A choice which is y = x + 4.
- The graph passes through y-axis at (0,4) which makes it obvious that the graph has y-intercept/b-value equal 4.
- The graph has slope of 1. We can tell by rise over run (A glance can tell that the graph has slope of 1.)
- Other choices have y-intercept at (0,0) also known as "origin point". The graph shown doesn't pass an origin point but passes through (0,4) as explained.
Here is the slope-intercept form, it might benefit you in some questions!

where m = slope and b = y-intercept.
Hope this helps! :)
We know that
[perimeter of rectangle]=2*[length+width]
length=(2x-7)
width=(x²-5)
[perimeter of rectangle]=2*[(2x-7)+(x²-5)]----> 2*[x²+2x-12]---> 2x²+4x-24 in
the answer is
(2x²+4x-24) in
