13) v2 - 110 + 18 = 0
14) 5x7 - 12x +7 = 0
Solve by factoring
Answers
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]
Solve. x2 – 10x + 21 < 0

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.)

Y=1/3x+7
Y=7x+1/3
Y=1/3x+6
Y=6x+1/3
Answers
Answer:
Y = 1/3x + 6
Step-by-step explanation:
You are trying to find the b in y=mx + b so you plug in the information you have
7=1/3 (3) + b
1/3 *3 = 1
7 = 1 +b
-1 - 1
6=b
So Y = 1/3x + 6

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?
Answers
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

What is an equation of the line that passes through the points (5,2) and (-5, -6)?
Answers
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
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?
Answers
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

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.
Answers
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
