The given equation can be expressed as xy²+7xy+5y-3=0.
What is an equation?When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions. In English, a well-formed formula with two expressions joined by an equals sign is referred to as an equation; however, cognates of this word in other languages may have slightly different meanings. For instance, the French definition of an equation is one or more variables.
Determine which values of the variables result in the equality to be true in order to solve an equation with variables. The values of the variables that must fulfill the equality to constitute the answer are known as the unknowns, together with the variables for which the equation must be solved. Equations can be classified as either conditional equations or identities.
Given,
(3/y)-5=x(y+7)
(3-5y)/y=(xy+7x)
3-5y=xy²+7xy
xy²+7xy+5y-3=0

Angle B = 23.4 degrees, Side A B = 3.3 millimeters, angle C = 90 degrees a. Side B C = 2.2 millimeters, Angle A = 66.6 degrees, Side A C = 2.4 millimeters c. Side B C = 3.0 millimeters, Angle A = 66.6 degrees, Side A C = 2.2 millimeters b. Side B C = 3.0 millimeters, Angle A = 66.6 degrees, Side A C = 1.3 millimeters d. Side B C = 1.3 millimeters, Angle A = 66.6 degrees, Side A C = 3.0 millimeters
*see attachment for the figure
Answer:
Side BC = 3.0 millimeters, Angle A = 66.6 degrees, Side AC = 1.3 millimeters
Step-by-step explanation:
Given:
C = 90°
B = 23.4°
AB = c = 3.3 mm
Required:
<A, BC, and AC
Solution:
✔️m<A = 180° - (90° + 23.4°) (sum of triangle)
m<A = 66.6°
✔️To find BC and AC, apply trigonometric function:
Reference angle = 23.4°
Hypotenuse = 3.3 mm
Opposite = AC
Adjacent = BC
✅Apply CAH to find AC:
Cos 23.4 = Adj/Hyp
Cos 23.4 = BC/3.3
3.3 × Cos 23.4 = BC
3.02859027 = BC
BC ≈ 3.0 mm
✅Apply SOH to find AC:
Sin 23.4 = Opp/Hyp
Sin 23.4 = AC/3.3
3.3 × Sin 23.4 = AC
1.31058804 = AC
AC ≈ 1.3 mm
Answer: B bc=3.0mm, A=66.6, AC=1.3mm

At Mr. Clark's shop, his employees work 20 hours each week and
earn $7 per hour. He uses this expression to find the
total weekly payroll for n employees.
7. (20. n)
Which is an equivalent expression that can be used to find the
total weekly payroll?
B
A 7. (20 − n)
(7 • 20).
с 20 · (n + 7)
D (n + 20) • 7
Answer:
B if there is an N at the end or beginning of it, Not sure if it cut off or not.
Step-by-step explanation:
Well you would need to do 20(7) to get 140, then multiply that to N. I would say B because I'm assuming you're missing out on some part of it, if it is N at the beginning or end then it is B.

A. square root
b. absolute value
c. inverse variation
d. linear
9514 1404 393
Answer:
a. square root
Step-by-step explanation:
For function f(x) = x², the inverse function is found by solving ...
x = f(y)
x = y²
If we take the square root of both sides of this equation, we get ...
√x = y
That is, the inverse of the quadratic function f(x) is ...
f⁻¹(x) = √x . . . . . square root

Find the measure of the missing angle.
Answer: 50
Step-by-step explanation:
A right angle is 90 degrees. A triangle must add up to 180 degrees. Add 40 and 90 to get 130. Then subtract 180 from 130 to get 50.
Answer:
? = 50°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 angles from 180° for ?
? = 180° - (90 + 40)° = 180° - 130° = 50°

Answer:
y = 2x + 3
Step-by-step explanation:
We need to find m and b
Let's input the first 2 points (3, 9) and (5, 13) into y = mx + b
9 = m*3 + b
13 = m*5 + b
subtract the first from the second
13 - 9 = m*5 + b - (m*3 + b)
4 = m*2
m = 2
Now let's input m = 2 into 9 = m*3 + b
9 = 2*3 + b
9 = 6 + b
3 = b
So the final relationship is y = 2x + 3
We can verify that the other two points (8, 19) and (11, 25) also conform to this relationship.

Mr. Davies plans to place an aquarium on a shelf in his living room. The length of the shelf is inches, and the aquarium is inches long. Which estimation is best for centering the aquarium on the shelf?
The question is incomplete as the length of the shelf and aquarium isn't given. However, steps to take in other to make the estimation of centering the aquarium on the shelf would be described.
Answer:
Kindly check explanation
Step-by-step explanation:
Let :
Lenght of shelf = x
Length of aquarium = y
Usually, the length of shelf will be > length of aquarium
The shelf will have the right and left hand side ;
Subtract Length of aquarium from length of shelf and divide the difference by 2 ;
(x - y) / 2 ; this will give the space or length left on either side of the shelf with the aquarium centered in the middle.
Hence, the aquarium should be placed at (x - y) / 2 meters either to the right or left of the shelf.
Just input the omitted values of shelf length and aquarium length to obtain the solution.

Answer:$32.86
Step-by-step explanation:
multiply the percent (6%) by 31$ which will get you 1.86. that's the tax amount. so then you add that to $31 and get $32.86
Answer:
C. 32.86
Step-by-step explanation:
The equation to calculate how much the tax is
31 x 0.06
This equals 1.86
Now add the original price and the tax amount together.
31 + 1.86 = 32.86
Therefore, the answer is 32.86

A recipe uses cups of milk to make servings. If the same amount of milk is used for each serving, how many servings can be made using gallon of milk?
Answer:
128 servings
Step-by-step explanation:
A recipe Uses 1 1/4 cups of milk to make 10 servings if the same amount of milk is used for each serving how many servings can be made using one gallon of milk
Cups of milk : number of servings = 1 1/4 cups : 10 servings
One gallon of milk = 16 cups
Let x = number of servings
Cups of milk : number of servings = 16 cups : x
Equate both ratios
1 1/4 : 10 = 16 : x
5/4 ÷ 10 = 16/x
5/4 × 1/10 = 16/x
5/40 = 16/x
1/8 = 16/x
Cross product
1 * x = 8 * 16
x = 128 servings
Number of servings = 128

4x - 1 = 2x + 9
Add 1 to both sides
4x = 2x + 9 + 1
4x = 2x + 10
Subtract '2x' from both side
4x - 2x = 10
2x= 10
Divide both sides by 2
x = 10/2
x = 5
