Answer:
x^2-5x-24
Step-by-step explanation:
Use the given x and y values to write a direct variation
equation. Enter your answer in the form y = kx.
x = 5, y = 50
The form is y = kx
Replace y and x:
50 = k(5)
Solve for k by dividing both sides by 5
K = 10

The hanger image below represents a balanced equation.
60
U
Find the value of u that makes the equation true.
Answer:
12
Step-by-step explanation:
Essentially, 60 and the 5 us must be equal:
60=5u
Divide both sides by 5 to solve for u but keep the equation balanced.
12=u

Which function describes this table of values? х у 10 8 5 4 0 0 -5 -4 y = 2 y= y = x - 2 y=-3
Answer:
y=4/5x
Step-by-step explanation:
If you multiply the x value of 10, substitute it into the equation. Using the equation y=4/5x, you will get the y value of 8.
When you substitute the x value of 5 into the equation. You will get 4.
You do this for the rest of the x values and will get the correct y values.
Only C please:)

Step-by-step explanation:
The f^-1 notation indicates you need to find the inverse of the function
y=2x+1
x=2y+1
Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x
7=2y+1
-2y=1-7
-2y=-6
Divide both side of the equation by -2
negative divide negative is positive so
y=3

Find an equation for y in terms of x
Answer:
y = [tex]\frac{9}{x^2}[/tex]
Step-by-step explanation:
Given y is inversely proportional to x² then the equation relating them is
y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of proportion
To find k use an ordered pair from the table
Using x = 3 when y = 1 , then
1 = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
9 = k
y = [tex]\frac{9}{x^2}[/tex] ← equation of proportion
JELP HURRY !!!!!!!!!
You should be able to set up a proportion between the sides something like (18+x)/x=(56+21)/56

If y ∝ [tex]\frac{1}{x}[/tex] and y = 4 when x = 2.5, find :
(a) y when x = 20
(b) x when y = 5
Answer:
Step-by-step explanation:
Y = k1/x
4 = k 1/2.5
2.5 x 4 = k
10 = k
Now using this equation we will find the other answers
A) find y when x = 20
Y = k 1/x
Putting values
= 10(1/20) = 1/2 = 0.5
B) find x when y = 5
Y = k 1/x
Putting values
5 = 10 1/x
5x = 10
x = 10/5 = 2

Firefighters used a ladder 50 feet high to reach a window that was 30 feet above the ground. From the same point on the ground, the ladder is turned to across the street to reach a window that was 40 feet high.
Select all the true statements.
The width of the street, BM, is 70 feet.
The ground distance of the ladder from building B is 30 feet.
The ground distance of the ladder from building M is 30 feet.
The width of the street, BM, is 122 feet.
The length KL is 50 feet.
Answer:
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40 Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30 line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street
Step-by-step explanation:
The width of the street, BM, is 70 feet. The ground distance of the ladder from building M is 30 feet. The length of KL is 50 feet.
What is Pythagoras's theorem?Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.
First, because two of the possibilities require the width of BM, let us solve for it using the Pythagorean theorem for both sides of point L.:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40
So, Line BL = 40 ft
So because the ladder is 50 feet long, it is also the same length on the other side.
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30
So, line LM is 30 ft
So line lm + line bl = 30 + 40 = 70 ft
Hence, the true statements are options (A), (C), and (E).

5. A joint of meat weighs 3.5 kg when frozen. It loses 8% of its weight
when it is thawed. Find the mass of the joint when thawed. *
Answer:
The mass of the meat when thawed is 7.72 kg (0.28 kg is lost)
Step-by-step explanation:
From the question, we are told that the weight loss amount is 8% of its initial weight
The mass lost here when thawed will be;
8/100 * 3.5 = 0.28 kg
So the mass of the joint will be;
8-0.28 = 7.72 kg
