Here we MUST follow Order of Operations rules.
Must start out by doing the work inside the parentheses: (8+7) = 15
Next, multiply this result by 3: 3(15)=45 (answer)
You will have to work out the given versions of this problem until you find one that is also equal to 45.
Answer:
(-3 ,2.5)
Step-by-step explanation:
midpoint formula is
x1+x2 y1+y2
(___ , _____ )
2 2
(-7,-2) -7 is x1 i.e the first x point and -2 is y1 1st y point
(1,7) 1 is x2 i.e the second x point and 7 is y2 the second y point
now we use input the numbers to the formula
-7+1 -2+7
(____ , --------)
2 2
we the signs are different you subtract and use sign of greater number
-6 5
__ , ___
2 2
Now you divide
and here is the ordered pair for midpoint.
(-3 ,2.5)
Set the equation equal to y
Add x to each side
7y=14 +x
Divide each side by 7
y=2 + x
The slope is whatever number corresponds with the variable x
In this case there is no number in front of the x which indicates that the slope is 1
90 ? Because it's rounding to the nearest tenth so .... it must be 90
