Answer:
That would be;
+52-20
Step-by-step explanation:
From the first part, he gained/earned 52 points
This is a positive so we have + 52
In the second round , he lost 20
This is a negative so we have - 20
Writing this as an addition problem, it will be;
+52-20

30x=40(x-1)
30x=40x-40
40=40x-30x
40=10x
x=4
Answer:
-35, 1.25, 2, 2
Step-by-step explanation:
have a good day!
Calculate the slope using the slope formula
m = (y2-y1)/(x2-x1)
m = (5-(-1))/(-6-(-8))
m = (5+1)/(-6+8)
m = 6/2
m = 3
The slope is 3
The point your teacher uses is (-6,5) because of the y-5. Note how it's in the form y-y1 where y1 = 5
So (x1,y1) = (-6,5)
Point Slope Form
y-y1 = m(x-x1)
y-5 = 3(x-(-6))
y-5 = 3(x+6)
The equation in point slope form is
y-5 = 3(x+6)
So you'll type 3(x+6) into the box
