2x - 3y = 3
y= 7 - 2x
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
Which of the following inequalities has the solution set shown on the graph?
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.

Which inequality correctly matches the graph?
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 thanks, show how you got the answer.
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

10. Rewrite into slope-intercept form 7x + y = 25
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)
Solve the linear equations
2y - 2x = - 30
x = 3y + 9
Answer:
1. Slope= 1.000
2. Slope= 0.333

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)
Diane sold some stuffs at a garage sale. She spent one-half of the money she made on a new bicycle. Next, she spent one-half of what was left on a portable stereo. If Diane had $40.00 left, how much money did she make from the garage sale
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
Answer:

What is the perimeter of triangle ABC?
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
