The table that shows a constant rate of change of -3 is Table D.
Option D is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The constant rate of change (r):
Take two ordered pairs (a, b) and (c, d)
= (d - b) / (c - a)
Now,
From Table D.
We see that,
r = (-1 - 2) / (-21 + 22) = -3/1 = -3
r = (-4 + 1) / (-20 + 21) = -3/1 = -3
r = (-7 + 4) / (-19 + 20) = -3/1 = -3
Thus,
The table that shows a constant rate of change of -3 is Table D.

(-3, -2)
Step-by-step explanation:
When the two lines intersect, f(x) = h(x)
2x + 4 = -1x - 5
Rearranging like terms together
3x = -9
x = -3
Substituting back into h(x) for x = -3
y = h(3) = 2(-3) + 4 = -2
So the point is (-3, -2)

A cabin on a ferris wheel has traveled one fourth of the circumference
of the wheel, a distance of 117.75 feet. What is the radius, in feet, of
the ferris wheel? Use 3.14 for pi
Answers
Solving for the circumference and using the formula for the circumference we got the radius as 74.95 feet
Mensuration of Flat ShapesGiven Data
1/4 of the circumference = 117.75 feet.
Let the circumference be x feet
1/4*x = 117.75
x/4 = 117.75
cross multiplying
x = 4*117.75
x = 471 feets
The expression for the circumference is given as
C = 2πr
471 = 2πr
Making r subject of formula we have
r = = 471/2*3.142
r = 471/6.284
r = 74.95 feet

Which symbol can be used to correctly compare the two fractionsPlease help asap!!!
Use >, <, or =.
2/5 35/100
Answers
Answer:
The symbol we can be used is " > "
Step-by-step explanation:
To compare two fractions you must make their denominator equal
Example:
To compare the fractions [tex]\frac{3}{4}[/tex] and [tex]\frac{7}{50}[/tex] ,
You should make their denominators equal. Multiply 4 by 25 to get 100 and multiply 50 by 2 to get 100, So, [tex]\frac{3*25}{4*25}=\frac{75}{100}[/tex] and [tex]\frac{7*2}{50*2}=\frac{14}{100}[/tex]. Since 75 > 14, then [tex]\frac{75}{100}>\frac{14}{100}[/tex] ,Which means [tex]\frac{3}{4}>\frac{7}{50}[/tex]Let us solve the question
∵ The fractions are [tex]\frac{2}{5}[/tex] and [tex]\frac{35}{100}[/tex]
→ Change denominator 5 to 100 by multiplying it by 20
∵ [tex]\frac{2}{5} =\frac{2*20}{5*20}=\frac{40}{100}[/tex]
∵ 40 > 35
∴ [tex]\frac{40}{100}>\frac{35}{100}[/tex]
∴ [tex]\frac{2}{5}>\frac{35}{100}[/tex]
∴ The symbol we can be used is " > "
Rewrite each equation without absolute value for the given conditions. y = |x−3| + |x+2| − |x−5| if x>5
Answers
Using the definition of the absolute value function, it is found that the equation is written as: y = x + 4
What is the definition of the absolute value function?It is the distance of a given point x to the origin(vertex of the function), hence the definition is as follows:
[tex]|x - a| = x - a, x \geq a[/tex]
[tex]|x - a| = -x + a, x < a[/tex]
Hence, considering that all expression are positive for x > 5, we have that:
|x - 3| = x - 3;|x + 2| = x + 2;|x - 5| = x - 5;Then, the expression is:
y = |x−3| + |x+2| − |x−5|
y = x - 3 + x + 2 - x + 5
y = x + 4

Step-by-step explanation:
Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard.She gave Php 1000.00 to the cashier.How much change will she?
Number of yards bought = 3/8
Cost of a yard = Phone 72.00
Cost of number of yards bought = Number of yards bought × Cost of a yard
= 3/8 × Php 72.00
= Php 27.00
She gave Php 1000.00 to the cashier.
How much change will she?
= Amount given to the cashier - cost of yards bought
= Php 1000.00 - Php 27.00
= Php 973.00

At the U.S. Open Tennis Championship a statistician keeps track of every serve that a player hits during the tournament. The statistician reported that the mean serve speed of a particular player was 100 miles per hourâ (mph) and the standard deviation of the serve speeds was 13 mph. If nothing is known about the shape of theâ distribution, give an interval that will contain the speeds of at least eight-ninths of theâ player's serves.
a. 74 mph to 126 mph
b. 61 mph to 139 mph
c. 48 mph to 152 mph
d. 139 mph to 178 mph
Answers
Answer:
b. 61 mph to 139 mph
Step-by-step explanation:
Chebyshev's theorem states that
For k> 1
1 - 1/k²
Where:
At least 75% or 3/4 of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.
At least 88.89% of 8/9 of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
From the question, we are told to find an interval that will contain the speeds of at least eight-ninths of the player's serves.
Mean (μ)= 100mph
Standard deviation (σ) = 13mph
At least 88.89% of 8/9 of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.
Hence:
μ - 3σ
100 - 3(13)
= 100 - 39
= 61 mph
μ + 3σ
= 100 + 3(13)
= 100 + 39
= 139 mph
Therefore, the interval is between 61 mph to 139 mph. Option b is correct

Find the Slope for the line which passes through these two points (-1,5) and (-4,-4).
Answers
Answer: positive 3 is the final answer
Step-by-step explanation:
Answer:
9/3 or just 3
Step-by-step explanation:
First we need to recognize that points are given by numbers that represent the x and y coordinates (or locations) of the point. So in this problem, the first point (-1,5) has an x value of -1 and a y value of 5. Similarly the second point has an x value of -4, and a y value of -4.
Slope is defined as rise over run, or change in y (rise as it goes up or down) over the change in x (or run as it moves left or right).
Change in x and y can be found by subtracting the first number from the second number.
So to calculate this, set up your equation like this:
[tex]\frac{5-(-4)}{-1-(-4)}[/tex]
After performing the subtraction, you should get:
[tex]\frac{9}{3}[/tex]
This further simplifies to 3.
