Answer:
30
40 - 5x
Step-by-step explanation:
Caroline is taking test worth 40 points that has 5 points per question. If she got 2 questions wrong, she would have a score of `30.
2 × 5 = 10
40 - 10 = 30
If Caroline got x questions wrong, she would have a score of 40 - 5x.
Answer:
18+8=26
Step-by-step explanation:
Their sum would be 18 and * because they have difference of ten. In order o get this you would have to multiply 1 X144 and so on.
The first step is to find the slope. Use the slope formula
m = (y2-y1)/(x2-x1)
The two points are (x1,y1) = (-1,5) and (x2,y2) = (2,-1)
So,
x1 = -1
y1 = 5
and
x2 = 2
y2 = -1
will be plugged into the slope formula to get...
m = (y2-y1)/(x2-x1)
m = (-1-5)/(2-(-1))
m = (-1-5)/(2+1)
m = (-6)/(3)
m = -2
The slope is -2
Use m = -2 and one of the points to find the y intercept b. I'll use the point (x,y) = (-1,5) ---> x = -1, y = 5
y = mx+b ... slope intercept form
5 = -2*(-1)+b
5 = 2+b
5-2 = 2+b-2
3 = b
b = 3
The y intercept is 3
-----------------------------------
m = -2 is the slope
b = 3 is the y intercept
Therefore y = mx+b turns into y = -2x+3 as the equation that goes through the two points
The answer I think if I’m correct is Minnie
First find the length of the side by taking the square root of 112.
There are 4 sides so multiply your answer by 4 to get the perimeter.
The answer is 42.332 which rounds to 42.
