Answer:

Option B. y+5=-\frac{9}{5}(x-3)

Step-by-step explanation:

step 1

Find the slope m

we have the points

(3, -5)\ and\ (-7, 13)

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

substitute the values

m=\frac{13+5}{-7-3}

m=\frac{18}{-10}

Simplify

m=-\frac{9}{5}

step 2

Find the equation of the line in point slope form

we know that

The linear equation in point slope form is equal to

y-y1=m(x-x1)

we have

m=-\frac{9}{5}

(x1,y1)=(3,-5)

substitute

y-(-5)=-\frac{9}{5}(x-3)

y+5=-\frac{9}{5}(x-3)

Solve the equation when x=12 1/3<br> Please show your work <br> 7x+8(x+1/4)=3(6x-9)-8
alina1380 [7]
7(12  1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8

12 1/3 = 12.33
1/4 = 0.25

7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 =  3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94

False. The x, when 12 1/3 does not work inside this equation

hope this helps

Variable termes X-12-3X+22
adell [148]

Answer: x + 12 = 3x + -22

12 + x = 3x + -22

Reorder the terms:

12 + x = -22 + 3x

Solving

12 + x = -22 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

12 + x + -3x = -22 + 3x + -3x

Combine like terms: x + -3x = -2x

12 + -2x = -22 + 3x + -3x

Combine like terms: 3x + -3x = 0

12 + -2x = -22 + 0

12 + -2x = -22

Add '-12' to each side of the equation.

12 + -12 + -2x = -22 + -12

Combine like terms: 12 + -12 = 0

0 + -2x = -22 + -12

-2x = -22 + -12

Combine like terms: -22 + -12 = -34

-2x = -34

Divide each side by '-2'.

x = 17

Simplifying

x = 17
