Answer:
Use the process of elimination. I'll only do one example since you have 4.
Step-by-step explanation:
Let's do the first question.
2x-3y=-11
2x+y=9
Our goal here is to be left with one variable to solve, this way we can use the answer for that variable to find the other. A.K.A only find X to plug into the equation to find Y. To do this, we'll use the process of elimination, in which we need to cancel out a variable.
X seems the easiest here. To cancel 2 (in the top equation), you need to have a -2. And that -2 needs to be the x coefficient in the 2nd equation, in order for us to "cancel" it out. To get -2, you multiply 2 by -1.
-1(2x+y)= -1(9)
Note that whatever you do to one side, you need to do it to both sides! Hence, why I also multiplied 9 by -1. You should now be left with:
-2x -y = -9
Now, we cancel out the positive 2 and -2 from both equations by adding the two equations.
2x-3y= 11
+
-2x-y=-9
X cancels out, so we're left with -4y=-20. Solve for Y, which is 5.
-4y=-20
y=5
Now that you have the Y value, plug it into any of the two equations to find your X value.
2x-3y=11
2x-3(5)=11
2x-15=11
2x=26
x=13
And voilah! Our Y value is 5, and our X value is 13.
It's pretty simple once you understand what's going on. All that we did was to cancel out one variable (either X or Y) in the two equations so that we're left with only one variable to solve. If we cancel out X, we only need to solve for Y. You do this by manipulating one of the two equations (doesn't matter which one). Once you find either X or Y, all you need to is to plug it into one of the original equations. Then, you'll have both X and Y.
And that my friend, is the process of elimination. Good luck!

Whats is 7 = 12v - 24?
Answer:
To the nearest tenth: v = 2.6
To the nearest hundredth: v = 2.58
Fraction form = 31/12
Step-by-step explanation:
1. Add 24 to both sides to cancel it out on the right
7 = 12v - 24
+24 +24
2. Divide each side by 12
31 = 12v
31/12 = 2.5833333
12/12 = 1v = v
v = 2.583333

How can you use the Distributive Property to check your work when factoring?
1. Once an expression has been factored, use the Distributive Property to expand the expression. The factored expression should be the original expression.
2. Once an expression has been factored, use the Distributive Property to factor the expression. The factored expression should be the original expression.
3. Once an expression has been factored, use the Distributive Property to factor the expression. The expanded expression should be the original expression.

Answer: 101 Degrees for angle BCD
Step-by-step explanation: All 3 angles in any triangle add up to 180, in the first triangle (one on the left), you have 58 and 78 degrees, add them both and subtract from 180, you get 44 degrees for angle C on the left. Do the same on the right side of the triangle, you should get 35 degrees for angle C on the right. Add them both up, (35+44) then subtract from 180 degrees to find the measure of angle BCD.

A girl's feet are negative 2 over 4 yards from the surface of a pool. A boy's feet are negative 3 over 4 yards from the surface of the pool. Determine whose feet are closer to the surface.
The girl's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 > negative 3 over 4.
The girl's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.
The boy's feet are closer to the surface of the pool because negative 2 over 4 < negative 3 over 4.

Y=4x +5 y=x -4 a (3, 17) b (-3, -7) c (-3, 7) d (3, 7)
Answer:
(-3, -7)
Step-by-step explanation:
y = 4x + 5
y = x - 4
add 4 to both sides of the second equation to get y + 4 = x
plug that back into the equation to get y = 4(y + 4) +5
distribute to get y = 4y + 16 + 5
combine like terms y = 4y + 21
subtract 4y on both sides to get -3y = 21
divide both sides by -3 to get y = -7
plug -7 into the second equation to get -7 = x - 4
add 4 on both sides to get -3 = x
therefore (-3, -7)

Your friend incorrectly factors the expression below as 6x(3-2xy). Factor the expression below correctly. What error did your friend make? 18x-12xy
Answer:
6x(3 - 2xy) = 18x - 12x²y
Step-by-step explanation:
My friend did -12xy instead of -12x²y
6x × 2xy = 12x²y
Answer:
Read explanation
Step-by-step explanation:
Your friend forgot to take the x out of 12xy when they factored it. when you factor out the 6x, you should write the equation as 6x(3-2y)
Andrew is driving to visit his grandmother. He drove 171 miles in 3 hours. What was his average rate of travel for the trip?
If Andrew drives 6 more hours at the same rate, what is the total number of miles traveled for the whole trip?
the answer would be
3hr = 171 miles
Average 57 miles per hour
if he drives 6 more it would be 513 miles in total

The first angle in a quadrilateral is 150 degrees. The second angle in the quadrilateral is 30 degrees.
The other two angles are congruent.
What are the angle measurements, in degrees, of angle 3 and angle 4?
Answer:
angle three is 30 degrees (depending on what kind of quadrilateral it is)
angle four is 150 degrees
Step-by-step explanation:
150+30
180 and if the other two are congruent meaning equal too
than they must also be 180 degrees in totale on the other side as well.
