2 would be "B" and 3 would "D"
Answer:
The slope is -.3125 and the y intercept is 25
The x intercept is 80
Step-by-step explanation:
2.5x+8y=200
We want to get this in slope intercept form so we will solve for y
Subtract 2.5x from each side
2.5x-2.5x+8y=-2.5x +200
8y = -2.5x +200
Now divide by 8 on both sides
8y/8 = -2.5x/8 + 200/8
y = -.3125x +25
This is in the form y = mx+b where m is the slope and b is the y intercept
The slope is -.3125 and the y intercept is 25
To find the x intercept, set y = 0 and solve for x
2.5x+8y=200
2.5x = 200
Divide by 2.5 on each side
2.5x/2.5 = 200/2.5
x =80
Answer:
D. 60, 45,75
Step-by-step explanation:
For options C and D
For a triangle the sum of the angles must always be equal to 180 degrees
So 180 ≠45+45+80
and
60 +45+ 75= 180
For option A and B
The length of the longer side is equal to the square root of the sum of squares of the other two sides in a triangle.
According to Pythagorus theorem
hypotenuse²= base² + perpendicular²
c²= a²+ b²
90²= 50² + 35²
8100= 2500+1225
8100≠3725
95²= 60²+ 25²
9025= 3600+ 625
9025≠4225
Therefore only D is the correct option
I just need points I’m sorry :(
The answer is B. your at -3, and add 4 more to -3, would make it -7
