Answer:
x = 10
Step-by-step explanation:
We need to isolate X.
3x - 7 = x + 13
subtract 13
3x - 7 - 13 = x
combine like terms
3x - 20 = x
subtract 3x
- 20 = x - 3x
Combine like terms
- 20 = - 2x
Divide by -2
10 = x
Drag graphs to show a graph of each equation in the table.
Answer:
Step-by-step explanation:
- The # in front of x will be the number that hits on the y-axis
- The # after x or the slope, ex: y = -1/2x + 2, is how much you move to hit the next point on the graph
- 2 would actually be 2/1 so move up 2 and right 1 (if the number or fraction is negative then go up and to the left
- So y = -2x - 1/2, negative slope. Start at -2 on y-axis and go up 1 then left 2.

Answer:
1) w = x+2
2) L = 12
3) w = 9
4) A = 108
Step-by-step explanation:
The rectangle has a length of x+5 and a perimeter of 4x+14.
Perimeter of a rectangle is given by all the lengths plus all the widths, ie 2*width and 2*length.
Perimeter = 2w + 2L
4x+14 = 2w + 2(x+5)
4x + 14 - 2x - 10 = 2w
w = 2x + 7 - x - 5
w = x+2 Width of the rectangle in terms of x.
If perimeter of rectangle is 42, what is the length?
Perimeter = 42 = 4x+14
28 = 4x
x = 7
L = x+5
L = 7+5
L = 12
If perimeter of rectangle is 42, what is the width?
Perimeter = 42 = 4x+14
28 = 4x
x = 7
w = x+2
w = 7+2
w = 9
Area equals length times width. What is the area of the rectangle.
A = L*w
A = 12*9
A = 108
Algebra 2!! What is the domain of the function graphed below?
Answer:
(-infinity,+infinity)
Step-by-step explanation:
Domain refers to the x-axis. So if we look from left to right along the x-axis we could conclude that the function will go infinitley from negative infinite to positive infinity.

List all the factors of 24.
Answer: 1,24. 2,12. 3,8. 4,6.
Step-by-step explanation:
If you change all of these factors to negatives, the pairs would also multiply together to produce positive 24.
Example: -1 x -24 = 24
-2 x -12 = 24, -3 x - 8 = 24.........

Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9

Answer:
D- Point D
Step-by-step explanation:
Well, if he earned $6 every hour he worked, 2 hours of work would be 12, 3 hours=18, 4 hrs.=24, etc.
you just multiply $6 by every hour worked.
Therefore, if you look at Point D is the only point plotted correctly.

Of Linear Eqitions by
Elimination
3x-y=0
2x+y=-10
Answer:
(-2, -6)
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
Hence the coordinate (x, y) is (-2, -6)

Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.
Answer:
Sample third quartile appears to be an unbiased estimator of the population third quartile.

Find the quotient
6 1/2 divided by 3/4
Answer:
8 2/3
Step-by-step explanation:
First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2 divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.

what is the value of x in the equation 24 equals 12 - 4x
Answer:
x = -3
Step-by-step explanation:
24 = 12 - 4x
24 - 12 = -4x
12 = -4x
12/-4 = x
x = -3
Answer:
x=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
24=12−4x
24=12+−4x
24=−4x+12
Step 2: Flip the equation.
−4x+12=24
Step 3: Subtract 12 from both sides.
−4x+12−12=24−12
−4x=12
Step 4: Divide both sides by -4.
−4x
−4
=
