Answer:
(-8,4)
Step-by-step explanation:
Given: 2x-3y=-28 and x+6y=16
solve for a variable and then substitute back into other equation
x + 6y = 16
x = 16 - 6y; now use this in the other equation
2x - 3y = -28; substitute into x
2(16 - 6y) - 3y = -28; distribute 2
32 - 12y - 3y = -28; combine y's
32 - 15y = -28; isolate 15y
32 + 28 = 15y; add the numbers
60 = 15y; divide by 15
y = 4
Now use this to plug into other equation
x + 6y = 16; y=4
x + 6(4) = 16;
x + 24 = 16; subtract 24 from both sides
x = -8
Answer:
15.6=c
Step-by-step explanation:
(12)^2+(10)^2=c^2
144+100=c^2
244=c^2
square root of both sides=244= square root c^2
15.620499=c
15.6=c
Answer:
The answer is C
Step-by-step explanation:
the lowest point of the box plot is at 1 and the highest is at 19, so by that it can't be A.
The box plot shows 12 being the median so that automatically leaves C but just to make sure the first half would be 6 and half of the last part would be 16 if that makes sense.
Answer: 16 units
Step-by-step explanation:
Point A and Point B are 5 units apart on the x-axis.
Since this is a rectangle, the opposite side is equivalent.
Point A and Point C are 3 units apart on the y-axis.
Same thing applies for these points.
5+5+3+3=16 units
When using the formula that lets you solve for the area of a traingle, you use
area = 1/2 base + height
which led me to solve and get 32.13
