Answer:
B. y=3x-2
Step-by-step explanation:
Regression line has positive slope value, it's rise from left to right.
y=3x-2 seems to be the most possible one
Answer:
Exact Form : 6/5
Decimal Form : 1.2
Mixed Nuumber Form ; 1 1/5
We find the slope through the formula y2-y1/x2-x1
so when we plug in the values of our two points, we get
2-(-1)/(0-(-1))
this gets us 3/1
Which gives us the slope m=3
The surface area of the composite shape is 1560 square inches
<u>Step-by-step explanation:</u>
The surface area of the top cardboard is,
SA = 5 x area of each side
Because one side is attached with another cardboard box . So while finding the area only 5 sides are calculated.
SA = 5 ( 10 x 10)
= 500 square inches
The surface area of the rectangular prism cardboard,
Given that,
l = 20 in
w =15 in
h = 8 in
A = 2(lw + wh + hl) - 100
We are subtracting 100 because it is the area of one side of the square cardboard box on top of the rectangular prism box .
A = 2(300 + 120 + 160) - 100
= 2(580) - 100
= 1160-100
= 1060 square inches
Total surface area = SA + A
= 500 + 1060
= 1560 square inches
The numbers are 17 and 39
We can use a system of equation to solve this
x=2y+5
x+y=56
Solving...
2y+5+y=56
3y=51
y=17
x=2(17)+5
x=39
