Amanda is practicing her dives off the diving board. When she dives into the water, the path her body makes and where she resurfaces can be modeled by the equation 0=2−8+7 where is the number of horizontal feet she travels. Solve the equation to find the number of feet she will travel before coming back to the surface of the water.
Answer:
The number of feet she will travel back is 1 or 7 feet
Step-by-step explanation:
Here, we need to solve the quadratic equation
That will be as follows;
0 = x^2 -8x + 7
x^2-x-7x+ 7 = 0
x(x-1)-7(x-1) = 0
(x-1)(x-7) = 0
x = 1 or 7
The number of feet she will travel before coming back to the surface of the water is 1 or 7 feet

Is 5x + 2 a numerical expression?
Answer:
Yes
Step-by-step explanation:
Yes, this is a numerical expression because x represents a number. This number is unknown, so x = 1 --- 5x (1) + 2 is equivalent to 5x + 2. 5x (1) +2 is a numerical expression, SO that means that 5x + 2 is a numerical expression.

y= 4x – 11
y=-8x + 13
Answer:
y=4x−11
Step 1: Flip the equation.
4x−11=y
Step 2: Add 11 to both sides.
4x−11+11=y+11
4x=y+11
Step 3: Divide both sides by 4.
[tex]\frac{4x}{4}[/tex] = [tex]\frac{y+11}{4}[/tex]
x= [tex]\frac{1}{4} y[/tex] + [tex]\frac{11}{4}[/tex]
y=-8x + 13
Step 1: Flip the equation.
−8x+13=y
Step 2: Add -13 to both sides.
−8x+13+−13=y+−13
−8x=y−13
Step 3: Divide both sides by -8.
[tex]\frac{-8x}{8}[/tex] = [tex]\frac{y- 13}{-8}[/tex]
x= [tex]\frac{-1}{8}y[/tex] + [tex]\frac{13}{8}[/tex]

The ratio of income Mr. John to his expenditure is 8 : 7. If his expenditure of one year is ₹ 1,26,000, what is his monthly income?
Answer:
₹ 12000 .
Step-by-step explanation:
It is given that,
The ratio of income Mr. John to his expenditure is 8 : 7
Expenditure = ₹ 1,26,000
Let the income is 8x and expenditure is 7x.
ATQ,
7x = 1,26,000
x = ₹ 18000
Yearly income = 8x
= 8(18000 )
= ₹ 144000
Monthly income,
[tex]M=\dfrac{144000}{12}\\\\=12000[/tex]
Hence, his monthly income is ₹ 12000 .
Write an equation to represent the following statement.
33 is 15 less than k.
Answer:
33 = k - 15
Step-by-step explanation:
This question can be solved but if your asking about equation 33 = k - 15 is it, because 33 is the total and 15 is less than k, whenever you see less than the number before is always the number telling the other number to subtract, such as 44 is 16 less than a number, the answer will be 44 = x - 16.
Which function is equivalent to f(x) = -4(x + 7) – 6?
Answer:
f(x) = - 4x - 34
Step-by-step explanation:
Given
f(x) = - 4(x + 7) - 6 ← distribute parenthesis
= - 4x - 28 - 6 ← collect like terms
= - 4x - 34
If the slope of y=2x+5 is changed to -2, how does the graph change?
The positive graph of y = 2x + 5 changes to the negative graph which moves downward from left to right when the slope is changed to -2.
What is Slope?Slope of a line is defined as the difference in the y coordinates divided by the difference in the x coordinates of two points.
Slope of a line is usually denoted by the letter m.
First let us take the graph of y = 2x + 5.
Take x intercept and y intercept of this graph.
x intercept is the point where line touches X axis and y intercept is the point where line touches Y axis.
From the equation of the line, y intercept = 5
So we get a point (0, 5)
Now to find x intercept, let y = 0 in the equation, then x = -2.5
So we get another point (-2.5, 0)
So the line y = 2x + 5 passes through the points (0, 5) and (-2.5, 0).
Now if the slope changed to -2, equation becomes y = -2x + 5.
y intercept is same.
So one point of the line will be (0, 5)
To find x intercept, let y = 0 in the second equation, then x = 2.5
So the second line passes through the points (0, 5) and (2.5, 0)
That is, the graph which goes upward from left to right changed to the graph downward from left to right.
Hence, when the slope changed to -2, the graph goes downward from left to right.

the length of a rectangle is 4cm more than double its width. the perimeter of the rectangle is 116cm. Find the length and the width of the rectangle
Answer:
l = 31 cm
w = 27 cm
Step-by-step explanation:
l = w + 4
p = 2l + 2w
p = 2(w+4) + 2w
116 = 2(w+4) + 2w
116 = 2w + 8 + 2w
116 = 4w + 8
108 = 4w
27 = w
l = w + 4
l = 27 + 4
l = 31

if f(x)=5x^4+3, then what is the remainder when f(x) is divided by x-1?
Answer:
8
This is actually fairly simple. If you take the x-1 and set it equal to 0 you get 1. And if you plug that value into the x you get 8, which is the remainder. This is called the remainder value theorem.

Last year ten examiners spent 6 hours marking all the exam papers.
This year the same process took only three hours.
How many examiners were there this time if they marked the same set of papers at the same rate?
Answer: 20 examiners.
Step-by-step explanation:
We know that 10 examiners need 6 hours to mark all the papers.
Then if R is the rate at which one examiner can mark all the papers, we have the equation:
(10*R)*6h = marking all the papers = 1
(i will use the 1 to represent the complete task)
then we have:
(10*R)*6h = 1
60h*R = 1
R = 1/60h
This means that only one examiner would need 60 hours to mark all the papers.
This time, we have N examiners, and they marked the same amount of papers in 3 hours, then we have thee equation:
(N*R)*3h = 1
(N*1/60h)*3h = 1
N*(3h/60h) = 1
N*(1/20) = 1
N = 1/(1/20) = 20
N = 20
This time, there are 20 examiners.
