Use the elimination method to solvethe system of equations. Choose the
correct ordered pair.
-x+y= -2
2x- 3y = 4
Answer: 2(−x+y=−2)
2(−x+y=−2)
1(2x−3y=4)
Becomes:
−2x+2y=−4
2x−3y=4
Add these equations to eliminate x:
−y=0
Then solve−y=0for y:
−y=0
−y/-1 = 0/-1 (Divide both sides by -1)
y=0
Step-by-step explanation:
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
−x+y=−2
Substitute 0 for y in −x+y=−2:
−x+0=−2
−x=−2(Simplify both sides of the equation)
−x/-1 = -2/-2 (Divide both sides by -1)
x=2
Answer:
x=2 and y=0
Answer: x=y+2
Step-by-step explanation:
Step 1: Add -y to both sides.
−x+y+−y=−2+−y
−x=−y−2
Step 2: Divide both sides by -1.
-x/-1 = -y - 2/-1
asnwer: x=y+2
Answer: x = 3/2y + 2
2x−3y=4
Step 1: Add 3y to both sides.
2x−3y+3y=4+3y
2x=3y+4
Step 2: Divide both sides by 2.
2x/2 = 3y + 4/2
answer: x = 3/2y + 2
Name a point on this line.
y - 8 = -7(x + 1)
(-1,8)
(1, -8)
(8,-1)
(-8,1)
Answer:
A
Step-by-step explanation:
You should approach this problem by plugging the answer choices into the equation, since there are only four that you need to do. A works because 8-8 = -7(-1+1) which are both equal to 0

50 Points if wrong u will get reported
Based on the fact that Mario increases by a scale factor of 2, the three points on the new Mario:
(7, 0)(0, 10.4)(4, 17.4)What are the new points?If Mario is increased by a scale factor of 2, then it means that all the points would be expanded by multiplying them by 2.
The first point would therefore be:
= 3.5 x 2 = 7
= 0 x 2 = 0
(7, 0)
The second point:
= 0 x 2 = 0
= 5.2 x 2 = 10.4
(0, 10.4)
The third point:
= 2 x 2 = 4
= 8.7 x 2 = 17.4
(4, 17.4)
The points on New Mario are:
(7, 0), (0, 10.4), and (4, 17.4)

Solve by combining:
-x-y=6
5x-7y=66
Answer:
x = 2
y = 8
Step-by-step explanation:
-x - y = 6
5x - 7y = 66
-x - y = 6
x = -y - 6
5x - 7y = 66
5 ( -y - 6 ) - 7y = 66
-12y - 30 = 66
-12y = 96
y = -8
x = -y - 6
x = 8 - 6
x = 2

3 Lila planted a tree in her backyard. She made this graph to show the tree growth for over 5 years. Part A Complete the equation to correctly show how to find the slope for the function shown in the graph.
Answer: Part A : slope = 20/1 -8/1 12/4 =3 Part B: The y-intercept is 5
Step-by-step explanation: I just did this with my teacher..Hope this helps! ( The numbers in bold are the answers)
The slope of the graph is 3 and the y intercept is 5.
A linear equation is in the form:
y = mx + b;
where y, x are variables, m is the slope of the line and b is the y intercept
Let y represent the height of the tree after x years.
The line passes through the point (0, 5) and (3, 14). Hence:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-5=\frac{14-5}{3-0} (x-0)\\\\y=3x+5[/tex]
Therefore the slope of the graph is 3 and the y intercept is 5.

Find an equivalent ratio in simplest terms: 30:18
Answer:
5:3
Step-by-step explanation:
To simplify the ratio, we have to divide both terms by the greatest common factor (GCF). The GCF is the highest number that can divide evenly into two or more numbers. The GCF of 30 and 18 is 6.
30/6 = 5
18/6 = 3
30:18 = 5:3
In montrel was -8 in new york it was 11 deggrees warmer, what was the tempreture in ny?
Answer:
3 degrees
Step-by-step explanation:
-8, -7 -6,-5,-4,-3,-2,-1,0, 1,2 3
If you count 11 spaces to the right on a number line, starting at -8, you will land at 3 degrees.
=========================================================
Explanation:
Think of the +11 as +8+3
Draw a vertical number line. Start at -8 on that number line. Then move up 8 units to arrive at 0. Afterward move the remaining 3 units to get to 3 on the number line. We've moved up a total of 8+3 = 11 degrees.
In other words, starting at -8 and moving up 11 units will have us arrive at 3
This visually shows -8+11 = 3
