Answer:
168
Step-by-step explanation:
7*-4=-28
-28*-6=168
Set up a system of equations:
B=2+3C
B+C=90
The variable B is already solved, so plug into bottom equation:
2+3C+C=90
2+4C=90
4C=88
C=22
Plug C back in:
B+22=90
B=68
So B is 68 degrees and C is 22 degrees

Answer:
the total distance is 56 cm
Step-by-step explanation:
Given that the area of the bulletin board is 196 cm^2
Based on this, the total distance around the bulletin board is
But before that we need to find out the side
As the area of square is
= side^2
196 = side^2
So side = 14
Now there are four sides, so the total distance is
= 4 × 14
= 56 cm
Hence, the total distance is 56 cm

Answer:
y= -2/7x-7
Step-by-step explanation:
slope intercept form is just a fancy way of saying y=mx+b
x being your input, y your output, m your slope, and b your y intercept
you can use the slope to determine your equation will look something like: y=-2/7x+b. To find your y-intercept all you do is determine how much the point will increase or decrease so it is equal to (0, y). In this case it will increase by 14 on the x's (so x is equal to 0) and 14*-2/7. When you have determined your y-int and slope you can then plug them into the equation instead of the variables.
