Answer:
8.9
Step-by-step explanation:
Parenthesis are always first so,
4.5+7.6=12.1
so the problem would look like this now:
12.1-8/2.5
so convert 8/2.5 to 8÷1/5÷2 so this will become 16/5
16.5 concerted to decimal=3.2
so 12.1-3.2=8.9
Greetings!To find the
y-intercept, we can arrange the equation in
slope y-intercept form:
Rearrange:


The
y-intercept is:
-13 
To find the
x-intercept, we can input the value
<<0>> in the place of y, as every x-intercept only occurs when
y=0:
Solve for x:




The
x-intercept is:

I hope this helped!
