the denominator cannot be zero as this would make the expression undefined. Equating the denominator to zero and solving gives the value that b cannot be
b - 2 = 0 ( add 2 to both sides )
b = 2 ← excluded value

Answer:
C = 8π
Area = 32π
Step-by-step explanation:
Radius = 4 cm
Circle Circumference Formula: 2πr
C = 2π*4 = 8π cm
Area Circle Formula: 2πr^2
Area = 2π*4^2 = 2π*4*4 = 2π*16 = 32π cm

The function f(x)is shown in the graph.
What is the equation for f(x)?
Answer:
(-5/6)x - 1
Step-by-step explanation:
the equation is given by: y = mx + b
m = slope
b = y intercept
m = -5/6
y intercept = -1
f(x) = (-5/6)x - 1
Which table represents a linear function?
Answer:
The last table.
Step-by-step explanation:
We can see that the last table is the only table that has y values that go up by the same value each time. If x goes up by 1, y goes up by 5. Therefore, the last table is the only table that represents a linear function.

Winifred bought a bib necklace, which is just a big necklace in the shape of a dinner bib, at a 45% discount. If the discount saved her $63, what was the necklace's original price?
$140 was the original price.
discount : 45%
45% ⇒ $63
1% ⇒ $(63/45)
1% ⇒ $1.4
original price is always 100%
100% ⇒ $(1.4*100)
100% ⇒ $140
Let the original price of the necklace be ,'x',
then,
According to the question,
(45/100)x = 6345x = 6300x = 6300/45x =140Hence ,the necklace she bought worths $140 without the discount given to her.

Hey ! there
Answer:
Option C - 72.22 units is the correct answer .Step-by-step explanation:
In this question we are given with diameter of circle that is 23 units and value of π as 3.14 . And We are asked to find the circumference of circle.
We know that ,
[tex] \qquad \qquad \: \underline{\boxed{\frak{ Circumference = \pi d}}}[/tex]
Where ,
π = 3.14d = diameter of circleSolution : -
[tex] \longrightarrow \qquad \: 3.14 \times 23[/tex]
By multiplying 23 with 3.14 we get :
[tex] \longrightarrow \qquad \: \red{ \underline{\boxed{\frak{72.22}}}}[/tex]
Henceforth , circumference of circle is 72.22 units .#Keep LearningWhat is the radius of a cone whose volume is 50 cubic units and whose height is 6 units?
Answer:
Radius = 2.8
Step-by-step explanation:
V = 1⁄3 πr² × h
50 = 1⁄3 πr² × 6
50 = 1⁄3 × 22⁄7 × r² × 6
50 = 22⁄21 × r² × 6
50 = 22⁄21 × 6 × r²
50 = 6.286 × r²
50 = 6.286r²
50/6.286 = 6.286r²/6.286
r² = 7.954
r = √7.954

A dog and a cat are 200 meters apart when they see each other. The dog can run at a speed of 30 meter per second, while the cat can run at a speed of 24 meters per second. How soon will they meet if they simutaneously start running towards each other?
Answer:
They'll meet after 200 meters , if they simultaneously start running towards each other.
Step-by-step explanation:
Let x =distance travelled by dog and 200-x be the distance travelled by cat. Inorder to meet, the sum of their travelled distances shall be equal to 200 meters as they are far apart by 200 meters.
Dog: Distance =Speed x time: x=30t
Cat: Distance = 200-x
=24t
The sum of their distance travelled shall be 200 meters: 30t+ 24t= 200;54t=200;t=200/54=3.7secs
So they will meet after 3.7 seconds
To check:
Distance travelled by dog :x=30(3.7)
=111.11 meters
Distance travelled by cat: 24t=24(3.7)
=88.89 meters
Therefore since they are travelling towards each other and their distance apart is 200 meters, after 3.7 seconds they will meet because dog travelled 111.11 meters and cat travelled 88.89 meters and they covered already 200 meters as the sum of 111.11+ 88.89
=200 meters

The correct statement is A that is The average size of an eighth-grade class is smaller and varies less than that of a seventh-grade class.
What are mean?The mean is the average value which can be calculated by dividing the sum of observations by the number of observations.
The mean of the seventh grade is given as 33.
The mean of the eighth grade is given as 30.
The correct statement is A because the mean absolute deviation of an eighth-grade class is less than that of a seventh-grade class.
Also, the class size is larger on average for seventh-grade classes (33 > 30).

If a rectangle has a length that is three times the width increased by 4. Find the dimensions of both the length and width if the
perimeter of the rectangle is 80 centimeters
Answer:
Step-by-step explanation:
Formula
The formula for perimeter is
P = 2L + 2w
Givens
Let the width = w
Length = 3w + 4
P = 80 cm
Solution
P = 2L + 2w
80 = 2(3w + 4) + 2w Remove the brackets
80 = 6w + 8 + 2w Combine
80 = 8w + 8 Subtract 8 from both sides
80-8 = 8w + 8-8 Combine
72 = 8w Divide both sides by 8
72/8 = 8w'8
9 = w
Answer
w = 9
L = 3*w + 4
L = 3*9 + 4
L = 31
3. Why is it helpful to work out long division problems with order and consistency?
[tex]\mathbb{ANSWER:}[/tex]
Long division helps in breaking the division problem into a sequence of easier steps. Just like all division problems, a large number, which is the dividend, is divided by another number, which is called the divisor, to give a result called the quotient and sometimes a remainder.

y=8x
Answer:
y = -x + 9
Step-by-step explanation:
the equation of a line is given by y = mx + b where m Is the slope and b is the y intercept.
as shown in the graph, the y intercept is 9.
how to find the slope:
the slope is rise over run and as we can see that the points move down once and to the right once at every exact point. hence, the slope is -1.
the equation: y = -x +9

The student council at Douglass High School is selling shirts for spirit week. So far, they have sold 58 long-sleeve shirts: 24 on Monday and 34 on Tuesday. Short-sleeve shirts have been less popular: they sold 18 of them on Monday and 25 on Tuesday. The student council earned $480 on Monday and $675 on Tuesday.
24x+18y=480
34x+25y=675
Now solve the system of equations you selected. What is the price of a long-sleeve shirt?
The student council sold long sleeve shirts for $12.50 and short sleeve shirts for $10.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the cost of long sleeve and y represent the cost of short sleeve, hence:
24x + 18y = 480 (1)
Also:
34x + 25y = 675 (2)
From both equations:
x = 12.5, y = 10
The cost of long sleeve shirts was $12.50 while short sleeve was $10 each.
