Answer:
Horizontal lines have no vertical change -- it continues straight left or right. In other words, the change in the y values between any points on the graph is 0, since there is no change. This means that the slope of a horizontal line is 0
Step-by-step explanation:
hope this helps
Answer:
0
Step-by-step explanation:
The line's slope remains constant throughout, its a line that passes through the y - axis therefore it's slope will be 0.

Answer:
x = 23
Step-by-step explanation:
These are supplementary angles so the sum of those angles add up to 180:
3x + 16 + 5x - 20 = 180
8x - 4 = 180
8x = 180 + 4
8x = 184
x = 184/8
x = 23
Write the rule that defines the function represented by the table
Answer:
y = 2 * 4^x
Step-by-step explanation:
We could define a wide variety of rules!
It turns out that any set of n (x, y) pairs can be modeled by a singular polynomial of degree (n-1) or less, and by infinitely many polynomials of degree n or more! And we're only talking polynomials!
Let's input it into a polynomial interpolation calculator:
[tex](27 x^4)/4 - (63 x^3)/2 + (225 x^2)/4 - (51 x)/2 + 2[/tex]
Well I don't love this.
Let's try to actually look for patterns. We see that the function is rapidly increasing. More and more, actually. Let's look for the ratios of each next y
8/2 = 4
32/8 = 4
128/32 = 4
512/128 = 4
BINGO!
So we can define the rule as:
y = 2 * 4^x

List the following fractions from least to greatest
Answer:
It would be number 3. 1/7,3/7,4/7,6/7
Step-by-step explanation:
For fractions if the denominator is the same you go to the numerator (the top number) to compare. The bigger the numerator is (like 6) the higher it should go on your list.
What whole number best approximates the value of x?
The answer is 87
For this problem, the method I used was more of a guess and check because I simply plugged the options into a calculator to see which one would be closest a little bit past 9.3 but not all the way 9.4
the square root of 87 is 9.32 so you would round down while the square root of 88 is 9.38 which would round up
Hope this helps :)

Simplify the expression:(2x-3y)^2/(3y-2x)^2 Ava simplified the expression and said that the value is -1. (2x-3y)^2/(3y-2x)^2 (2x-3y)^2/-(2x-3y)^2 and then she has both of them crossed out (2x-3y)^2/-1(2x=3y)^2 =-1 Is Ava's solution correct? If not, find and explain her mistake. Give the correct solution.
Answer:
Ava is incorrect
Step-by-step explanation:
Given
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2}[/tex]
[tex]Ava: \frac{(2x - 3y)^2}{(3y - 2x)^2} = -1[/tex]
Required
Determine if Ava is correct or not
Ava's solution is incorrect and the proof is as follows;
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2}[/tex]
Apply the following law of indices;
[tex]\frac{a^n}{b^n} = (\frac{a}{b})^n[/tex]
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2} = [\frac{2x - 3y}{3y - 2x}]^2[/tex]
Rewrite the numerator
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2} = [\frac{-(3y - 2x)}{3y - 2x}]^2[/tex]
Cross out the common factor of the numerator and denominator
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2} = [\frac{-1}{1}]^2[/tex]
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2} = [-1]^2[/tex]
[tex]\frac{(2x - 3y)^2}{(3y - 2x)^2} = 1[/tex]
Hence, the solution is 1; not -1
Her mistake is that, she did not apply the square on -1, after she factorize the denominator

incorrect

9. The formula V=lwh is the volume formula for a rectangular prism. Find the length (l) of a prism with volume (V) 1200 cm³, width (w) 15 cm, and height (h) 8 cm.
A. 6 cm
B. 8 cm
C. 10 cm
D. 14 cm
please show how you got the answer!
Answer:
C. 10cm
Step-by-step explanation:
First we can rearrange the equation to solve for length (l):
V = lwh
Divide both sides by wh:
l = V/(wh)
Substitute in known values:
l = 1200/(15x8)
l = 1200/120
l = 10cm

An uber charges a flat rate of $6 plus $1.25 per mile. Kayla can spend no more than $27.50. If she wants to tip her driver $4, what is the greatest number of miles she can uber?
Answer:
14
Step-by-step explanation:
to determine the answer
Subtract the amount she wants to tip from the total amount of money she wants to spend
$27.50 - $4 = $23.50
Let m = total miles
the total miles she intends to drive can be determined using this equation
$23.50 = $6 + $1.25m
Collect like terms
$23.50 - $6 = $1.25m
$17.50 = £1.25m
Solve for m
17.50 / 1.25 = 14
The designer sketched a model of the pond. The model drawing had a circumference of 24 inches. What is the AREA of the model she drew? Show your work. Round your answer to the nearest tenth.
Answer:
Area of model pond = 45.6 inch² (Approx.)
Step-by-step explanation:
Given:
Circumference of circular pond = 24 inches
Find:
Area of model pond
Computation:
Circumference of circle = 2πr
Circumference of circular pond = 2πr
24 = 2[22/7][r]
Radius r = [24 x 7] / [2 x 22]
Radius r = 3.81 inch (Approx.)
Area of circle = πr²
Area of model pond = πr²
Area of model pond = (22/7)(3.81)²
Area of model pond = [3.1428][14.5161]
Area of model pond = 45.6 inch² (Approx.)

Here is a system of linear equations: -2x + y = 7
6x + y = 11
What is the solution to the system of equations shown?
A
(1/4, 7 1/2)
B.
(2, 11)
c.
(1/2, 8)
D.
(3, -7)
Yes
Answer:
c. (1/2, 8)
Step-by-step explanation:
To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.
Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.
-2x + y = 7
Step 1: Subtract y from both sides of the equation.
-2x = -y + 7
Step 2: Divide both sides by -2
x = 1/2y - 7/2
Substitute what you see above this statement for y in the other equation.
6(1/2y - 7/2) + y = 11
Step 3: Multiply 6 by 1/2y - 7/2.
3y - 21 + y = 11
Step 4: Combine y and 3y.
4y - 21 = 11
Step 5: Add 21 to both sides
4y = 11 + 21
4y = 32
Step 6: Divide both sides by 4.
y = 32/4
y = 8
Step 7: Substitute 8 for y in x = 1/2y - 7/2 Because the resulting equation contains only one variable, you can solve for x directly.
x = 1/2(8) - 7/2
Step 8: Multiply 1/2 by 8.
x = 4 - 7/2
Step 9: Add -7/2 to 4.
x = 1/2
The system is now solved, and we get C (1/2, 8) as our answer.

A country's population in 1992 was 103 million. In 1997 it was 108 million. Estimate the population in 2012 using the exponential growth formula. Round your answer to the nearest million.
p=Aekt
the awnser is 123 million I am sure of it
Answer:123 million.
Step-by-step explanation: From 1992 to 1997, it grew by 5 million in 5 years. That means it grew by a million people every year. 2012-1997=15. That means it grew by 15 million. 108+15=123.

Based on this data, what is a reasonable estimate of the probability that the Texas Sharpshooters score exactly
Answer:
The answer is "Its next hockey game is probably the Texas Sharpshooters who've had exactly 1 goal 0.5".
Step-by-step explanation:
The exploratory probabilities are called chances of possible dangers based on previous cases.
[tex]Experimental \ probabilities = \frac{Appropriate \ results}{Total\ results}[/tex]
The chance which Texas Sharpshooters will be scoring precisely
Next game of 1 goal
If demonstrated at the table:
Positive effects are 1 repeated 4 times
So, positive results [tex]= 4[/tex]
Outcomes total [tex]= 8[/tex]
Odds [tex]= \frac{4}{8} = 0.5[/tex]
The probability that Texas Sharpshooters will achieve exactly 1 goal is 0.5
