Answer: x=2
Step-by-step explanation: Step 1: Simplify both sides of the equation.
2(2−x)=4(−2+x)
(2)(2)+(2)(−x)=(4)(−2)+(4)(x)(Distribute)
4+−2x=−8+4x
−2x+4=4x−8
Step 2: Subtract 4x from both sides.
−2x+4−4x=4x−8−4x
−6x+4=−8
Step 3: Subtract 4 from both sides.
−6x+4−4=−8−4
−6x=−12
Step 4: Divide both sides by -6.
−6x
−6
=
−12

Answer:
1)the x-axis
2) when reflecting a shape over the x-axis the x coordinate stays the same and the y-coordinate becomes the opposite, so positive numbers become negative numbers and negative numbers become positive
Step-by-step explanation:
the rule of reflecting over the x-axis is (x, y)->(x, -y)
m=(-5,4)->(-5,-4)
n=(-2,3)->(-2,-3)
l=(-4,2)->(-4,-2)

Answer:
5 units right and 3 units up
Step-by-step explanation:
A shift 5 units to the right, and then a shift 3 units up.
k = +3
+k shifts function up; -k shifts function down,so 3 units up
h = -5
x+h shifts function left; x-h shifts function right, so 5 units right

Step-by-step explanation:
You need to use the distance formula.
[tex]\sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2}}[/tex]
Ex: (1,2) and (1,16)
You will need to lable each
1st Point: 1 will be [tex]x_{1}[/tex] and 2 will be [tex]y_{1}[/tex]
2nd Point: 1 will be [tex]x_{2}[/tex] and 16 will be [tex]y_{2}[/tex]
Then you will need to plug it in

I need help with this finding x problem please show work
Answer:
The model represents the equation
-3x + 6 = 4x -8
Start by subtracting 6 from both sides.
-3x + 6 (-6) = 4x - 8 (-6)
-3x = 4x - 14
Subtract 4x from both sides
-3x - 4x = 4x - 4x - 14
-7x = -14
x = -14/-7
x = 2

The total change in yards for the two plays 21 yards lost
what are integers?Integers include all whole numbers and negative numbers. This means if we include negative numbers along with whole numbers, we form a set of integers.
Definition of IntegersAn integer is a number with no decimal or fractional part and it includes negative and positive numbers, including zero. A few examples of integers are: -5, 0, 1, 5, 8, 97, and 3,043. A set of integers, which is represented as Z, includes:
Positive Numbers: A number is positive if it is greater than zero. Example: 1, 2, 3 . . .
Negative Numbers: A number is negative if it is less than zero. Example: -1, -2, -3 . . .
Zero is defined as neither a negative number nor a positive number. It is a whole number.
In first play= 14 yards lost= -14
In next play = 7 yards lost = -7
So,
the total change in yards is = -14 + (-7)
=-14-7
= -21 yards

The vertices of a triangle are A (-2, 2), B (4,10), and C (0, -2). Find the equation of the line that contains
the median through point
The equation of the line is y =________
Answer:
y = 1/2 x + 3
Step-by-step explanation:
mid point of line BC = (2, 4)
slope of the line containing median (m) = 1/2
y intercept (b)= 3
since y = mx + b
y = 1/2x + 3
The median of a triangle is the line segment joining the any of the vertex to the mid-point of the opposite side of that vertex. The equation of the median through point A is given by y = 1/2x + 3.
What is a Median ?A median of a triangle is a line segment joining one of the vertex of the triangle to the mid-point of the opposite side.
The median of an equilateral triangle also an angular bisector.
Given that,
The coordinates of A = (-2, 2)
The coordinates of B = (4, 10)
The coordinates of C = (0,-2)
Thus the coordinate mid-point of BC is given by (4+0)/2,(10-2)/2 = (2,4).
Now, to find the equation of median through A there are two points (-2,2) and (2,4).
Thus the equation of median an be written as,
(y-2)/(x+2) = (4-2)/(2-(-2))
=> y - 2 = 1/2(x+2)
=> y = 1/2(x+2) + 2
=> y = 1/2 x + 3
Hence, the equation of the line is y = 1/2 x + 3.

Lauren is twice Kristy’s age. The sum of Lauren and Kristy’s ages is 51. Which equation represents the sum of their ages?
A K + K + 2 = 51 B K + 2K + 2 = 51 C 2K = 51 D K + 2K = 51
Answer:
D. K+2K=51
Step-by-step explanation:
Since Lauren is 2 times Kristy's age, Lauren's age=2K
so, if the sum of the two is 51, then 2K+K=51
If you want to solve it, 2K+K=3K=51
51/3=K
17=K
34=L
Answer:
D K + 2K = 51
Step-by-step explanation:
Lauren is twice Kristy's age so it would be 2K cause you want to multi[ly, and then you have to add Kristy's age in the equation because their ages added together is 51

Answer:
A: (3x+24):3x = 85:51
Step-by-step explanation:
85 seems to be the total (RT + TP). 51 seems to be just TP alone.
This means that for the side lengths above, it should be in this format:
(length of QP):(length of SP)
The length of QP is 3x+24, as 3x is SP and QS is 24.
The length of SP is just 3x.
I hope this made sense, please leave a comment if it didn't ^^'
Answer:
∆RPQ ~ ∆TPS
now
RP: TP=QP:SP
(34+51);51=(3x+24):3x
(3x+24):3x=85:51 is your answer

The point (0, 0) is a solution to which inequality? A. y – 9 3x + 10 C. y – 9 > 3x – 10 D. y + 9 > 3x + 10
Let x = 0
Let y = 0
Look at choice A. There is a typo here. This is not an inequality. Where is choice B? No choice B given.
Let us play with choice C and D.
y - 9 > 3x - 10
0 - 9 > 3(0) - 10
-9 > 0 - 10...This is a true statement. We know that -9 is bigger than -10. Do you know why this is true?
How about D?
Again let y = 0 and x = 0.
0 + 9 > 3(0) + 10
9 > 0 + 10
9 > 10...This is untrue. We know that 9 is NOT BIGGER than 10.
Without knowing A and B, I figured out that choice C is true. We conclude that the point (0,0) AKA the origin is a solution to the inequality given by choice C.
