It's D: (0,0)

This is because when you put 0 in for x your y value will equal 0 and that is one of your answers, so it's the point (0,0)

But equation in y intercept form.. what ever is in front of the x will be the slope for that equations line

5x=y-12

5x+12=y or y=5x+12

Slope is 5

If any line is parallel to this one it must have slope of 5

5x=y-12

5x+12=y or y=5x+12

QUESTION POSTED AT 28/03/2020 - 12:41 PM

If you want an answer to question: You can make the equations equal to each other and solve for x. So, since the y values are the same, we can do

(+x)5x+6 = -x-7. (+x)

(-6)6x+6= -7(-6)

(1/6) x 6x= -13 x (1/6)

x= -13/6

Substitute −13/6 for x in y=5x+6:

y=5x(−13/6) + 6

y = -29/ 6.

**y= -29/6 and x= -13/6**

(+x)5x+6 = -x-7. (+x)

(-6)6x+6= -7(-6)

(1/6) x 6x= -13 x (1/6)

x= -13/6

Substitute −13/6 for x in y=5x+6:

y=5x(−13/6) + 6

y = -29/ 6.

Choice A. Work done below:

4x-1=5x-8 ( Set the opposite sides equal to each other).

4x-5x-1=-8 (Subtract 5x on both sides)

-x-1=-8 (Combine like terms)

-x=-8+1( Add 1 on both sides)

-x=-7 (Now since you have a negative sign on both sides you can cancel them)

x=7 ( Making that as your answer!!)

4x-1=5x-8 ( Set the opposite sides equal to each other).

4x-5x-1=-8 (Subtract 5x on both sides)

-x-1=-8 (Combine like terms)

-x=-8+1( Add 1 on both sides)

-x=-7 (Now since you have a negative sign on both sides you can cancel them)

If they give you what one variable is, you can plug it into the equation and use algebra to solve it. So:

1)2x=4 -> 4/2 = 2 so x=2

2) y=0

3) x=3

4) 2y + (3*3y) = -15

11y=-15

y = -15/11

5) 4x + 7x + 63 = 19

11x = -44

x = -4

1)2x=4 -> 4/2 = 2 so x=2

2) y=0

3) x=3

4) 2y + (3*3y) = -15

11y=-15

y = -15/11

5) 4x + 7x + 63 = 19

11x = -44

x = -4

QUESTION POSTED AT 28/03/2020 - 11:46 AM

To determine the value of x in our equation, "5x = 16", we need to divide both sides by 5 to get x by itself.

Divide 5 and 16 by 5.

5x/5 = x, 16/5 = 3.2.

x = 3.2

I hope this helps!

QUESTION POSTED AT 28/03/2020 - 11:21 AM

I'm assuming the 5x should be a 5y.

4x - 2y = 16

4x - 5y = 8

I would use the elimination method since the coefficients on the x variable are the same.

Subtract the second equation from the first equation.

4x - 2y = 16

-(4x -5y = 8)

-------------------

3y = 8

y = 8/3

Plug */3 back in for y and solve for x.

4x -2y = 16

4x -2(8/3) = 16

4x - (16/3) = 16

add (16/3) to both sides.

4x = (16/3) + (48/3)

4x = (64/3)

multiply both sides by (1/4) to clear the 4

x = (64/3)(1/4)

x = 16/3

(16/3, 8/3)

4x - 2y = 16

4x - 5y = 8

I would use the elimination method since the coefficients on the x variable are the same.

Subtract the second equation from the first equation.

4x - 2y = 16

-(4x -5y = 8)

-------------------

3y = 8

y = 8/3

Plug */3 back in for y and solve for x.

4x -2y = 16

4x -2(8/3) = 16

4x - (16/3) = 16

add (16/3) to both sides.

4x = (16/3) + (48/3)

4x = (64/3)

multiply both sides by (1/4) to clear the 4

x = (64/3)(1/4)

x = 16/3

(16/3, 8/3)

Remember, you can do anything to an equation as long as you do it to both sides

get 1 of the x on one side

5x-14=8x+4

minus 5x both sides (we want on left side because 8>5 and I like positive stuff)

5x-5x-14=8x-5x+4

0-14=3x+4

-14=3x+4

minus 4 both sides

-14-4=3x+4-4

-18=3x+0

-18=3x

divide both sides by 3

remember, negative/positive=negative

-18/3=(3x)/3

-6=x(3/3)

-6=x(1)

-6=x

x=-6

get 1 of the x on one side

5x-14=8x+4

minus 5x both sides (we want on left side because 8>5 and I like positive stuff)

5x-5x-14=8x-5x+4

0-14=3x+4

-14=3x+4

minus 4 both sides

-14-4=3x+4-4

-18=3x+0

-18=3x

divide both sides by 3

remember, negative/positive=negative

-18/3=(3x)/3

-6=x(3/3)

-6=x(1)

-6=x

x=-6

**Answer:**

Hi!

The correct answer is 4x-5.

**Step-by-step explanation:**

- X is the years of Amy.
- If you want to multiply by four the years of Amy, then you have 4X.
- If you want to substract five years at four the years of Amy, then you have 4X - 5.

Example:

Amy's age 20, so X = 20.

Ava's age is Y.

- Y = 4X - 5
- Y = 4*20 - 5 = 75.

The inflection points are when acceleration is equal to zero. If the above graph is dy/dx, acceleration will be equal to zero when the slope of it is zero because that will mean velocity is constant at that point.

So if the graph of dy/dx has horizontal slopes at x=2 and 4, they are the x-coordinates of the inflection points of f(x).
