Iteru [2.4K]

Answer:

-2

Step-by-step explanation:

Slope formula:

    ↓

\frac{Y_2-Y_1}{X_2-X_1}=\frac{Rise}{Run}

Y_2=7\\Y_1=1\\X_2=2\\X_1=5\\

\frac{7-1}{2-5}=\frac{6}{-3}=\frac{6\div-3}{-3\div-3}=\frac{-2}{1}=-2

<em>Therfore the slope is -2.</em>

Solve the system of linear equations by substitution
ziro4ka [17]

y - x = 0  ...equation 1
2x - 5y = 9 \: ...equation  \: 2
working with equation 1
y = x \: ...equation \:  3
next subsitue equation 3 in equation 1
2x - 5(x) = 9
2x - 5x = 9
- 3x = 9
divide by -3
x =  - 3
substitute x= -3 in equation 1
y - ( - 3) = 0
-(-3) = + 3
y =  - 3

If a and b are supplementary angles and m∠a=2x+6and m∠b=x+3,find m∠a
aliya0001 [1]

Answer:

114

Step-by-step explanation:

Supplementary means that all the angles in your givens add up to 180 degrees.

Givens

<A + <B = 180

<A = 2x + 6

<B = x + 3

Solution

<A + <B = 180                   Substitute for <A and <B

2x + 6 + x + 3 = 180          Combine like terms on the left.

3x + 9 = 180                      Subtract 9 from both sides

3x = 180 - 9

3x = 171                             Divide by 3

x = 171/3

x = 57            

That's not your answer.

<A = 2x + 6

<A = 2*57

<A = 114
