Answer:

the solution is (18, 3)

Step-by-step explanation:

Let's first eliminate x.  Multiply the second equation by 2, obtaining

2x = 6y + 18

Then add this result to the first equation 2y - 2x = -30:

2x = 6y + 18

2y - 2x = -30

--------------------  or

2x = 6y + 18

-2x = -30 - 2y

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

0 = 4y - 12, which yields y = 3.

Substitute 3 for  y in the second equation to obtain the value of x:

x = 3(3) + 9, or x = 18

Then the solution is (18, 3).

Note that we could do this faster by reducing 2y - 2x = -30 to y - x = -15

Then the second equation becomes x = 3(y) + 9, or

                                                              x = 3y + 9, with x = 18

Then 18 = 3y + 9, or 3y = 9, or y = 3 (as before)

Answer:

x=3 y=1

Step-by-step explanation:

plug in y. 2x-3(7-2x)=3

then get 8x=24

x=3

then plug in x in either equation

y=7-2(3)

y=1

Answer:

18 units

Step-by-step explanation:

Using the midpoint theorem, the perimeter of the triangle formed by joining the midpoints of the original triangle is exactly half the size in perimeter

What we mean in this case is that the perimeter of BAC IS two times the perimeter of EDF

perimeter of EDF is the sum of all the sides = 2 + 4 + 3 = 9

So the perimeter of BAC is 2 * 9 = 18

Answer:

option A)  y > 5/4x + 10

Step-by-step explanation:

Take any point in the shaded region

( -12 , 1)

y > 5/4 x + 10

1 > 5/4 * (-12) + 10

1 > 5*(-3) +10

1 > -15 + 10

1 > -5

(-12 , 5) satisfies the equation.

Answer:

The inequality correctly matches the graph is -2 < x < 4 ⇒ B

Step-by-step explanation:

From the given figure

∵ There is a segment drawn from -2 to 4

∴ The starting point of the inequality is -2

∴ The ending point of the inequality is 4

∵ The endpoints of the segments are white circles (not shaded)

→ That means the signs of inequality without sign =

∴ The values of x are between -2 and 4

∴ The inequality is -2 < x < 4

∴ The inequality correctly matches the graph is -2 < x < 4

Answer:

B. PK = 15, RJ = 9

Step-by-step explanation:

RQ = 3

PQ = 5

✔️In ∆JKL, Q is the centroid. According to the centroid theorem, thus:

⅓(RJ) = RQ

⅓(RJ) = 3

Multiply both sides by 3

RJ = 3*3

RJ = 9

✔️Also, based on the centroid theorem,

⅓(PK) = PQ

⅓(PK) = 5

Multiply both sides by 3

PK = 5*3

PK = 15

Answer:

Y = 4X - 6

Step-by-step explanation:

Slope of linear equation = change in Y / change in X

As Y is changing +4 units, with change in X +1 units.  [ -6 - (-2) ] / [ 1 - 0 ]

So, slope = 4

Y = A + BX

Y = A + 4X  , as B = slope & A = intercept

Putting values of X & Y (0,-6)

-6 = A + 4 (0)

A = -6

Hence, Equation : Y = 4X - 6

Answer:

$160

Step-by-step explanation:

Diane sold some stuffs at a garage sale.

Let the total value of the money Diane made = x

She spent one-half of the money she made on a new bicycle.

Amount spent on a Bicycle = 1/2 × x = 1/2x

Next,

Amount left

= x - 1/2x = 1/2x

She spent one-half of what was left on a portable stereo.

Amount spent spent on Portable stereo

= 1/2 × 1/2x

= 1/4x

If Diane had $40.00 left,

Hence:

The fraction of what was left is calculated as:

= x - (1/2x + 1/4x)

= x - (3/4x)

= 1/4x

Hence:

1/4x = $40

We can find the value of x now.

1/4 × x = $40

x/4 = $40

x = $40 × 4

x = $160

Therefore, the amount she made from the garage sale is $160

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 5ˣ - 12

f(3) is x = 3

Step 2: Evaluate

To write in slope-intercept form, you first need to get y by itself. To do this, subtract 7x from both sides of the equation.

Doing this gets you: y = 25 - 7x

Now that y is by itself, remember that slope-intercept form looks like this: y = mx + b

So, let's switch the right side.

y = -7x + 25

Slope intercept form is: y = -7x + 25

Rules for y in Slope-Intercept form:

y must be positive

y must be by itself (so, not 2y, or anything with it... just y)

Answer:

a)First, solve and regroup

11=y-5x

y=11+5x.

Plug in:

6x-2(5x+11)=-6

6x-10x-22=-6

-4x-22=-6.

-4x=16

x=-4.

Plug it:

y=11+5(-4)

y=11-20

y=-9.

x,y=-4,-9.

b) The error Tim made is that he confused the x and y.

The correct answer is -4,-9.

He said it was -9,-4.

Hope this helps plz hit the crown ;D

The correct solution is -4,-9 time might have changed x coordinate with y-coordinate

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

6x-2y = -6...1

11= y-5x...2

(a) Rearranging the 2 equation;

11=y-5x

y=11+5x.

substituting in first equation;

6x-2(5x+11)=-6

6x-10x-22=-6

-4x-22=-6.

-4x=16

x=-4.

Now putting the value of x in second equation;

y=11+5(-4)

y=11-20

y=-9.

x,y=-4,-9.

(b) The error Tim made is; he confused the x and y.

The correct answer will be -4,-9.
