Answer:
The answer is b
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Given
x² - 7x - 44
Consider the factors of the constant term (- 44) which sum to give the coefficient of the x- term (- 7)
The factors are - 11 and + 4 , since
- 11 × 4 = - 44 and - 11 + 4 = - 7 , thus
x² - 7x - 44 = (x - 11)(x + 4) ← in factored form
with (x - 11) as a factor → B

A recipe requires 1/3 cup of sugar for every 3/4 cup of flour. How many cups of sugar are required for every cup of flour?
Answer:
4/9 cup of sugar
Step-by-step explanation:
[tex]\frac{1}{3} cup of sugar= \frac{3}{4} cup of flour[/tex]
[tex]? cup of sugar=1 cup of flour[/tex]
so crisscross them and finally you'll get
1/3*4/3=4/9
For 1 cup of flour, 4/9 cups of sugar is needed.
What are ratios and proportion?Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -
A : B ∷ C : D
AND
A x D = B x C
Product of extremes equal to product of means.
Given is a recipe that requires 1/3 cup of sugar for every 3/4 cup of flour.
Now -
For 1/3 cup of sugar = 3/4 cup of flour is needed.
For 1 cup of flour = (1/3)/(3/4) cups of sugar = 1/3 x 4/3 = 4/9 cups of sugar is needed.
Therefore, for 1 cup of flour, 4/9 cups of sugar is needed.

Make x the subject of Y=4x+3
The value of x from the expression is,
⇒ x = 1/4 (Y - 3)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The equation is,
⇒ Y = 4x + 3
Now, We can solve the expression for the value of x as;
⇒ Y = 4x + 3
Subtract 3, we get;
⇒ Y - 3 = 4x + 3 - 3
⇒ Y - 3 = 4x
Divide by 4;
⇒ (Y - 3) / 4= 4x/4
⇒ (Y - 3)/4 = x
⇒ x = 1/4 (Y - 3)

A gym offers three levels of membership based on the number of visits per month, as represented by the table. Kaleigh wants to know how much she will pay for her gym membership. Which graph represents the total monthly cost at the gym as a function of the number of visits Kaleigh plans to make each month?
Answer:
graph one
Step-by-step explanation:
Let
x ----> the number of visit per month
y ----> the total cost
we know that
Observing the table
1) For the interval of x equal to ----> [0,12] (close circle both points)
The domain is all whole numbers greater than or equal to 0 visits and less than or equal to 12 visits
The value of y is
y=5x+15
For x=0 ----> y=$15
For x=12 ----> y=5(12)+15=$75
The range is the interval ----> [15,75] (close circle both points)
All real numbers greater than or equal to $15 and less than or equal to $75
2) For the interval of x equal to ---->(12,16] (open circle at left and close circle at right)
The domain is all whole numbers greater than 12 visits and less than or equal to 16 visits

The graph that represents the total monthly cost at the gym as a function of the number of visits in a month is shown by option A)
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Based on the number of visits each month, a gym provides three different levels of membership.
Let the monthly visits be 'a' and the overall expense be 'b'. The following will be the appropriate graph showing the total monthly cost of the gym as a function of monthly visits:
A) For the interval of a = [0,12]
The value of b is given by:
b = 5a + 15
when a = 0 in the above equation.
b = $15
when a = 12 in the above equation.
b = 60 + 15
b = $75
The interval of b = [15,75]
B)
For the interval of a = [12,16]
The value of b is given by:
b = 4a + 32
when a = 12 in the above equation.
b = 48 + 32
b = $80
when a = 16 in the above equation.
b = 64 + 32
b = $96
The interval of b = [80,96]
C)
For the interval of a = [16,24]
The value of b is given by:
b = 3a + 42
when a = 16 , we get
b = 48 + 42
b = $90
when a = 24 in the above equation , we get
b = 72 + 42
b = $114
The interval of b = [90,114]

Explanation:
Starting at (4, -1) and moving four units up will have us arrive at (4, 3). We add 4 to the y coordinate and keep the x coordinate the same. The algebraic rule is stated as [tex](x,y) \to (x,y+4)[/tex].
Next, we reflect over the y axis. This will have us flip the sign of the x coordinate while keeping the y coordinate the same. The algebraic rule for this kind of reflection is [tex](x,y) \to (-x,y)[/tex]. The point (4,3) reflects over the y axis to get to (-4,3)
So we started at (4, -1), then moved four units up to get to (4,3) and then reflected over the y axis to get to (-4, 3) which is the final stop.
This is all shown in the diagram below.

The base of an isosceles triangle is 4/5. The perimeter of the triangle is 4\2\15 what is the length of either of the remaining equal sides
Answer:
1 2/3
Step-by-step explanation:
Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...
4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15
Then either of the remaining sides is half this value, or ...
(4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3
Each of the remaining sides has length 1 2/3.

It takes 48 minutes for 7 people to paint 7 walls. How many minutes does it take 20 people to paint 20 walls?
Answer: 48 minutes
Step-by-step explanation:
If there are 7 people painting 7 walls, we can assume that 1 person is painting 1 wall. Altogether they can each paint in 48 minutes.
If there are 20 people painting 20 walls, it would also equal 48 minutes because each person can paint in that time.
Answer:
137 minutes.
2 hrs and 17 minutes
Step-by-step explanation:
The painting of each wall takes 6.85 minutes.
48 / 7 = 6.85.
therefore if there are 20 walls, it must take 20 people 2 hrs and 17 mins
20 x 6.85 = 137minutes.

The circumference of the hub cap of a tire is 76.87 centimeters. Find the area of this hub cap. Use 3.14 for pi. Use pencil and paper. If the circumference of the hub cap were smaller, explain how this would change the area of the hub cap.
The area of this hub cap is about
blank square centimeters.
Answer: The area of this hub cap is about 470.46 square centimeters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Circumference (C) = 2π radiusReplacing with the values given:
76.87 = 2 (3.14) r
Solving for r (radius)
76.87/ (2x 3.14) =r
r = 12.24 cm
To find the Area:
Area of a circle = π r^2A = 3.14 (12.24)^2
A = 470.46 cm2
If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.

Which equations could you solve using the addition property of equality? Check all that apply. 4 + y = 100 y – 4 = 100 4y = 100 4 + 100 = y 100 = y – 5
Answer:
y-4=100 and 100=y-5
Step-by-step explanation:
Because the addition property of equality is: The property stating that adding the same number to both sides of an equation does not change the equation.
Equations are used to represent equal expressions
The equivalent equation of y + 4 = 100 is 4 + y = 100
How to determine the equationsThe equation is given as:
y + 4 = 100
Rewrite the equation as follows:
4 + y = 100
Hence, the equivalent equation of y + 4 = 100 is 4 + y = 100

in the bank until it reaches 20100 dollars?
A= P(1 + -]nt
Answer:

A=p(1+r/n)^nt
A=$20100
P=$6500
r=7%=0.07

t=?
t=ln(A/P)/n {ln(1+r/n)}
=ln(20100/6500) / 4{ln(1+0.07/4)}
=ln(3.0923)/4{ln(1+0.0175)}
=ln(3.0923)/4{ln(1.0175)}
=1.1289/4(0.0174)
