Your photo is super blurry! I can’t read parts of the problems, so I can’t exactly help you. Sorry! Good luck.
Answer:
35 minutes
Step-by-step explanation:
2 hrs 4 min= 160 min
3 hrs 15 min= 195 min
195-160=35
Answer:
y+10 = 2 (x+1)
Step-by-step explanation:
slope = (y2-y1)/(x2-x1)
m = (2--10)/(5--1)
m = (2+10)/(5+1)
m = (12/6)
m=2
point slope form
y-y1 = m(x-x1)
y--10 = m(x--1)
y+10 = 2 (x+1)
Q1: y = -3/2x +1
Q2: The graph changes vertically from -1 to 3 (4 units) at the same time it changes horizontally from -4 to 1/2 (4.5 units). The rate of change is 4/4.5 = 8/9 ≈ 0.8889. The closest answer selection is 9/10.
Q3: x=-2
Q4: The graph changes vertically by -4 at the same time it changes horizontally by +1. The slope is 4/-1 = -4. The y-intercept is +1, so the equation is
.. y = -4x +1
Q5: After the same pattern as above,
.. y = 5/2*x +5
No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.
The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.
So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.
