Answer is D. (–10, –30)
when x = -10 then y = <span>3x = 3(-10) = -30</span>
Answer:
You will save: $15
Total cost: $60
Step-by-step explanation:
First turn the percent into a decimal.
To do so move the . over to the left twice.
20% - .20
Now multiply 75 by .20
75 x .20 = 15
So you will save $15
Now subtract 15 from 75
75 - 15 = 60

Answer:
28+66+86=180
180=180
Step-by-step explanation:
Since there is a triangle and the 3 measures from the angles we can find the value of x using the hint given that the sum of the interior angles must be 180°
Write the equation
\begin{gathered}x+(2x+10)+(3x+2)=180\\\end{gathered}
x+(2x+10)+(3x+2)=180
Simplify left side of the equation
\begin{gathered}6x+12=180\\\end{gathered}
6x+12=180
Solve equation for x
\begin{gathered}6x=180-12\\6x=168\\x=28\end{gathered}
6x=180−12
6x=168
x=28
Replace x into the 3 angles and find their respectives values
\begin{gathered}A=x\\A=28\\\\B=2x+10\\B=2*28+10\\B=56+10\\B=66\\\\C=3x+2\\C=84+2\\C=86\end{gathered}
A=x
A=28
B=2x+10
B=2∗28+10
B=56+10
B=66
C=3x+2
C=84+2
C=86
Check if the answers are correct
\begin{gathered}28+66+86=180\\180=180\end{gathered}
28+66+86=180
180=180

Answer:
5593.75
Step-by-step explanation:
Answer:
m = y-b/x
Step-by-step explanation:
y = mx + b
0 = - y + mx + b
-mx = -y + b
m = -y + b / -x
m = y - b / x
