can someone solve x - 8 = -3x + 12
and x + 12 = -x - 6
STEP BY STEP PLEASE? !
Answer:
x-8= -3x+12
adding 8 and 3x on both sides
x-8+8+3x= -3x+3x+12+8
x+3x=20
4x=20 divide by 4
x=5
x+12= -x-6
adding x and subtacating 12 on both sides
x+x+12-12= -x+x-6-12
2x = -18 divide by 2
x= -9
Damarcus and Xavier went to the arcade to play their two favorite games. Damarcus played 4 rounds of game 1 and 6 rounds of game 2 for $18.00. Xavier played 5 rounds of each game for $20. What is the cost of game 1? A. $1.00 B. $2.00 C. $3.00 D. $4.00
Answer:
The correct option is (c).
Step-by-step explanation:
Let x and y denote the cost of game 1 and game 2 respectively.
ATQ,
4x+6y = 18 ....(1)
5x + 5y = 20 ....(2)
Multiply equation (1) by 5 and equation (2) by 4.
20x+30y = 90 ....(3)
20x + 20y = 80 ....(4)
Subtracting equation (3) and (4)
20x+30y - (20x + 20y) = 90-80
20x-20x+30y-20y = 10
10y = 10
y = 1
Put the value of y in equation (1).
4x+6(1) = 18
4x = 18-6
4x = 12
x = 3
Hence, the cost of game 1 is $3.00

The given equations are
12x + 4y = 152 ...........1
32x + 12y = 420 .....2
Multiplying equation 1 by 3 to make coefficient of y same we have:
36x+12y= 456
32x+12y=420
Subtracting the two equations we have:
4x=36.
Dividing by 4 both sides
x= 9.
Substituting x value in equation 1
12(9) + 4y = 152
108+4y=152
Subtracting 108 both sides: 4y=44.
Dividing both sides by 4.
y=11.

Which of the following best describes how to measure the spread of the data?
The IQR is a better measure of spread for movies than it is for basketball games.
The standard deviation is a better measure of spread for movies than it is for basketball games.
The IQR is the best measurement of spread for games and movies.
The standard deviation is the best measurement of spread for games and movies.
Answer:
C. The IQR is the best measurement of spread for games and movies
Step-by-step explanation:
In a box plot, the Interquartile Range (IQR) can be gotten by finding the range of the rectangular box. That is, The third Quartile (Q3) - the first quartile (Q1).
The IQR is a measure of spread, and it would be appropriate for measuring spread of the data for both Movies and Basketball games displayed by the box plot.

Please help!! I have posted this several times but no responses!

There is no picture attached
Step-by-step explanation:
If f(1) = 5 and f(n) = 5f(n − 1) then find the value of f (5).
Answer:
f(1)= 5
so x=1
f(5)= 5(5-1) = 20
The value of f(5) is 3125.
What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
f(1) = 5 and f(n) = 5f(n − 1)
Now, for finding the the 5 th term we have to find the remaining four term before the 5th term.
So, n=2
f(2) = 5f(1)
f(2)= 5(5)
f(2)= 25
Now, n=3
f(3) = 5f(2)
f(3)= 5(25)
f(3)= 125
Now, n=4
f(4) = 5f(3)
f(4)= 5(125)
f(4)= 625
Now, n=5
f(5) = 5f(4)
f(5)= 5(625)
f(5)= 3125
Hence, the value of f(5) is 3125.

Answer:
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.
Step-by-step explanation:
Given equations of lines are:
Line p: x+2y=1
Line q: y=2x+1
We can determine if two lines are parallel or perpendicular by comparing the slopes of line.
Slope intercept form of line is given by the formula
[tex]y = mx+b[/tex]
Equation of line q is already in slope intercept form.
We have to convert the equation of line p in slope-intercept form
[tex]x+2y = 1\\2y = -x+1\\2y = -\frac{1}{2}x+\frac{1}{2}[/tex]
Slope of line p = 2
Slope of line q = -1/2
We can see that
[tex]2.-\frac{1}{2} = -1[/tex]
The product of slopes of both lines is -1, hence, the lines are perpendicular.
Hence,
The correct answer is:
Option 2: Yes, because the slopes of lines are negative reciprocals.

What’s 25 dived by 9 in long (step by step)
Answer:
Step 1:
Start by setting it up with the divisor 9 on the left side and the dividend 25 on the right side like this:
9 ⟌ 2 5
Step 2:
The divisor (9) goes into the first digit of the dividend (2), 0 time(s). Therefore, put 0 on top:
0
9 ⟌ 2 5
Step 3:
Multiply the divisor by the result in the previous step (9 x 0 = 0) and write that answer below the dividend.
0
9 ⟌ 2 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (2 - 0 = 2) and write the answer below.
0
9 ⟌ 2 5
- 0
2
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
9 ⟌ 2 5
- 0
2 5
Step 6:
The divisor (9) goes into the bottom number (25), 2 time(s). Therefore, put 2 on top:
0 2
9 ⟌ 2 5
- 0
2 5
Step 7:
Multiply the divisor by the result in the previous step (9 x 2 = 18) and write that answer at the bottom:
0 2
9 ⟌ 2 5
- 0

Step 8:
Subtract the result in the previous step from the number written above it. (25 - 18 = 7) and write the answer at the bottom.

Answer:
Domain: [0, ∞)
Range: [7850, ∞)
Step-by-step explanation:
A function is defined by the set of ordered pairs having different output values for every input value.
In the graph attached, for every input value (x-coordinates) there is a unique output (y-coordinates) value.
Therefore, graph represents a function.
Domain of the given function → [0, ∞)
