Answer:

x = 1 and y = 5

Step-by-step explanation:

Use substitution because you know that x = y - 4, and plug this into the first equation to get -10(y - 4) + 3y = 5, or -10y + 40 + 3y = 5. This is -7y = -35 so y = 5. Plug this into the 2nd equation to get that x = 1 and y = 5.

Find the point-slope equation for the line that passes through the points (5,19) and (-5,-1).
xxTIMURxx [149]

Answer: y - 19 = 2(x - 5)

Step-by-step explanation:

The point slope form is expressed as

y - y1 = m(x - x1)

Where

m represents slope

Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis

change in the value of y = y2 - y1

Change in value of x = x2 -x1

y2 = final value of y

y 1 = initial value of y

x2 = final value of x

x1 = initial value of x

The given points are (5,19) and (-5,-1)

y2 = - 1

y1 = 19

x2 = - 5

x1 = 5

Slope,m = (- 1 - 19)/(- 5 - 5) = - 20/- 10 = 2

To determine the equation, we would substitute x1 = 5, y1 = 19 and m= 2 into the point slope form equation. It becomes

y - 19 = 2(x - 5)

#1

= 9

Let's solve your equation step-by-step.

8.88=4.44(x−7)

Step 1: Simplify both sides of the equation.

8.88=4.44(x−7)

8.88=(4.44)(x)+(4.44)(−7)(Distribute)

8.88=4.44x+−31.08

8.88=4.44x−31.08

Step 2: Flip the equation.

4.44x−31.08=8.88

Step 3: Add 31.08 to both sides.

4.44x−31.08+31.08=8.88+31.08

4.44x=39.96

Step 4: Divide both sides by 4.44.

#2

= y = -3

 

Step 1: Simplify both sides of the equation.  

Step 2: Subtract 2 from both sides.  

Step 3: Divide both sides by 5.
