Answer:

28/5=x and y=  -6/5

Step-by-step explanation:

solve by substitution

3x+4y=12

Rewrite equations:

2x+y=10;3x+4y=12

Step1: Solve 2x+y=10 for y:

2x+y=10

2x+y+−2x=10+−2x(Add -2x to both sides)

y=−2x+10

Step2: Substitute−2x+10 for y in 3x+4y=12:

3x+4y=12

3x+4(−2x+10)=12

−5x+40=12(Simplify both sides of the equation)

−5x+40+−40=12+−40(Add -40 to both sides)

−5x=−28

-5x/-5=-28/5

(Divide both sides by -5)

x=  28/5

Step3: Substitute

28/5 for x in "y=−2x+10":

y=−2x+10

y=−2(28/5)+10

y=-6/5(Simplify both sides of the equation)

Hope this helps!

Write equations for the horizontal and vertical lines passing through the point (-2,-5).
erastova [34]

Answer:

  • y = -5
  • x = - 2

=============================

The horizontal line has same y- coordinate for each x- coordinate, and is parallel to the x-axis so it is:

  • y = - 5

The vertical line has same x- coordinate for each y- coordinate, and is parallel to the y-axis so it is:

  • x = - 2

Can someone help me with this please?
Andrei [34K]
Question 2: B

(x+4) is canceling out so it is the hole.

x+4=0 and x= -4 is the hole.

(x+1)=0 is vertical asymptote so x= -1 is vertical asypmtote.

Question 3: D

x²-5x-14 factors to (x-7) and (x+2)  

(X+2 )cancel outs so it is a hole at x= -2 

x-7=0 and x=7 is a vertical asymptote
