Answer:
x=(3y-11)/5
3(y-2)= 5(x+1) by cross multiplication
5x+5=3y-6
5x=3y-6-5
5x=3y-11
We divide by 5 on both sides

Samantha plays on the softball team for her school she strikes out twice after nine times she is at bat if she struck out 14 times this season how many times has she got back
Answer:
she got back 63 times
Step-by-step explanation:
Here, we want to know the number of times she is at bat
from the question, we are made to know that she strikes out twice after 9 times
So striking out 14 times, the number of times she has got back will be ;
14/2 * 9 = 63 times

In a survey of 1,700 people who owned a certain type of car, 425 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
25%Step-by-step explanation:
Given;
Total people surveyed = 1700 people
Total number of people that owned car = 425 people;
Percentage of people satisfied are those that owned car = 425/1700 * 100
Percentage of people satisfied = 42500/1700
Percentage of people satisfied = 25%
Hence 25% of the people surveyed were satisfied with the car

A cookie factory uses 1 1/3 barrels of oatmeal in each batch of cookies. The factory used 2 2/3 barrels of oatmeal yesterday. How many batches of cookies did the factory make?
Answer:
2 batches
Step-by-step explanation:
A cookie factory uses 1 1/3 barrels of oatmeal in each batch of cookies
The factory used 2 2/3 barrels of oatmeal yesterday
Therefore the batches of cookies that were made yesterday can be calculated as follows
1 batch= 1 1/3 barrels
x = 2 2/3 barrels
Cross multiply
4/3 x = 8/3
x= 8/3 ÷ 4/3
x = 8/3 × 3/4
x= 2
Hence 2 batches will be produced

Choose a point, any is fine. (I chose point c)
Count how many spaces it to get from point C to where point C' is on the x axis. (It already gave it to us. its 8)
Then count how many spaces it takes to get to C' on the y axis. (In this case you are counting down because A'B'C' is beneath ABC.)

Step-by-step explanation:
1. Find the area of each sector. Give your answer in two forms. 1) in terms of it and 2) using 3.14 for it.
Round all answers to the nearest tenth.
Answer:
1.
1) The area of the sector is 168.8π mi²
2) The area of the sector is 529.9 mi²
2.
1) The area of the sector is 42.3π in²
2) The area of the sector is 132.7 in²
Step-by-step explanation:
The formula of the area of a sector in a circle is A = [tex]\frac{x}{360}[/tex] × π r², where
x is the central angle subtended by the arc of the sectorr is the radius of the circle1.
∵ The central angle subtended by the arc of the circle is 270°
∴ x = 270°
∵ The radius of the circle is 15 mi.
∴ r = 15
→ Substitute them in the formula of the area above
∵ A = [tex]\frac{270}{360}[/tex] × π (15)²
∴ A = 168.75π mi²
→ Round it to the nearest tenth
∴ A = 168.8π mi²
1) The area of the sector is 168.8π mi²
∵ π = 3.14
∴ A = 168.75 × 3.14
∴ A = 529.875 mi²
→ Round it to the nearest tenth
∴ A = 529.9 mi²
2) The area of the sector is 529.9 mi²
2.
∵ The central angle subtended by the arc of the circle is 90°
∴ x = 90°
∵ The radius of the circle is 13 in
∴ r = 13
→ Substitute them in the formula of the area above
∵ A = [tex]\frac{90}{360}[/tex] × π (13)²
∴ A = 42.25π in²
→ Round it to the nearest tenth
∴ A = 42.3π in²
1) The area of the sector is 42.3π in²
∵ π = 3.14
∴ A = 42.25 × 3.14
∴ A = 132.665 in²
→ Round it to the nearest tenth
∴ A = 132.7 in²
2) The area of the sector is 132.7 in²

5x>20
Answer:
x > 4
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Inequality
5x > 20
Step 2: Solve for x
Divide 5 on both sides: x > 4Here we see that any value x greater than 4 would work as a solution to the inequality.
Change the following equation from standard form to Slope-Intercept Form.
7x - 4y= 28
Answer:
y = [tex]\frac{7}{4}[/tex] x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
7x - 4y = 28 ( subtract 7x from both sides )
- 4y = - 7x + 28 ( divide all terms by - 4 )
y = [tex]\frac{7}{4}[/tex] x - 7 ← in slope- intercept form
Find the slope of the line that passes through the points (-4, 3) and (7, 5).
Answer:

13) v2 - 110 + 18 = 0
14) 5x7 - 12x +7 = 0
Solve by factoring
Answer:
see explanation
Step-by-step explanation:
(13)
v² - 11v + 18 = 0 ← in standard form
(v - 2)(v - 9) = 0 ← in factored form
Equate each factor to zero and solve for v
v - 2 = 0 ⇒ v = 2
v - 9 = 0 ⇒ v = 9
solutions are v = 2, v = 9
(14)
5x² - 12x + 7 = 0
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 7 = 35 and sum = - 12
The factors are - 5 and - 7
Use these factors to split the x- term
5x² - 5x - 7x + 7 = 0 ( factor the first/second and third/fourth terms )
5x(x - 1) - 7(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(5x - 7) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
5x - 7 = 0 ⇒ 5x = 7 ⇒ x = [tex]\frac{7}{5}[/tex]
solutions are x = 1, x = [tex]\frac{7}{5}[/tex]

What is an equation of the line that passes through the points (5,2) and (-5, -6)?
Answer:
y=4/5x+2
Hi! first things first, you want to find the slope. you do that by taking both y values, in this case they are 2 and -6.
then, you need to identify the two 2 x values, 5 and -5.
next, follow this formula: Y2-Y1/X2-X1. y value#2 is -6, and y value#1 is 2. subtract those numbers, to end up with -8. this will go on top of the fraction. x value#2 is -5, x value#1 is 5. subtract (=-10) and put it on the bottom of the fraction.
now you have your slope! we now have y= -8/-10, or simplified is 4/5.
Now we find the y intercept. to do that, you want to pick a set of points. i'm going to be using (5, 2) because it will be the easiest.
lastly, set up the equation to find the y int: y- y1= m (x- x1)
y- 2= 4/5 (x- 5) = 2

Which Graph does NOT show a linear function?! HELP PLS
Answer:
The top right corner
Step-by-step explanation:
I hope you have a good day
Answer:
2nd One
Step-by-step explanation:
The answer is the 2nd one because it is not a line, and the rest are functions. This line is curved. Non-linear functions mean the graph is not a straight line, which would perfectly describe this one because it starts straight and curves up.
