Which is a solution to the equation?
(x - 3)(x - 5) = 35
Ox= -8
O x= -5
O x= 2
O x = 10
Answers
Answer:
x=10
Step-by-step explanation:
Let's solve your equation step-by-step.
(x−3)(x−5)=35
Step 1: Simplify both sides of the equation.
x2−8x+15=35
Step 2: Subtract 35 from both sides.
x2−8x+15−35=35−35
x2−8x−20=0
Step 3: Factor left side of equation.
(x+2)(x−10)=0
Step 4: Set factors equal to 0.
x+2=0 or x−10=0
x=−2 or x=10

What is perimeter of the semi circle?
Answers
Answer:
54.22 mm
Step-by-step explanation:
Find the circumference of the circle and then divide it by 2.
We start with the formula for the circumference for the circle:
C = 2πr
To find r, divide 22 by 2:
22/2=11
Now find the cicumference:
C = 2πr = 2(3.14)(11) = 108.46 mm
NOW, to find the perimeter of the semicircle, divide the circumference by 2:
108.46/2 = 54.22 mm
A concert venue has 20 seats in the first row and an 5 additional seats in each successive row. If there are 35 rows of seats then how many people can attend a sold-out show? 3,675 190 2,100
Answers
Answer:
3,675 people
Step-by-step explanation:
First row, a = 20
Common difference, d = 5
number of terms, n = 35
Sn = n/2 {2a + (n - 1)d}
= 35/2 {2*20 + (35 - 1)5}
= 35/2 {40 + ( 34)5}
= 17.5(40 + 170)
= 17.5(210)

Aaron is having rain gutters installed around the perimeter of his roof. How much will he spend if he is charged $3.50 per foot?
Answers
Answer:
$294.35
Step-by-step explanation:
left and right side of the house: 15 ft + 15 ft = 30 ft
top part of the house: (20 ft - 12 ft = 8 ft) 8ft + 9.6 ft + 7.5 ft = 25.1
bottom part of the house: (20 ft - 15 ft = 5 ft) 15 ft + 5 ft + 4. 5 ft + 4.5 ft = 29
30ft + 25.1ft + 29ft = 84.1

Step-by-step explanation:
area for a triangle is 1/2 the base times the height.
IN order to find out the base you need to multiply the area by two and then divide by 42 to find the base. X will represent the base
so
336 *2 = 42x
672= 42x

Let g(x) be the reflection across the x-axis of the function f(x) = 7x + 3. Identify the rule for g(x).
Answers
Answer:
(x,y) => (x, -y)
Step-by-step explanation:
[tex]y = 7x + 3[/tex]
[tex] - y = 7x + 3[/tex]
[tex]y = - 7x - 3[/tex]
so
[tex]g(x) = - 7x - 3[/tex]
Hence, [tex]g(x) = - 7x - 3[/tex].
What is the function?
Functions are often defined by a formula that describes a combination of arithmetic operations and previously defined functions; such a formula allows computing the value of the function from the value of any element of the domain.
Here given that,
Let [tex]g(x)[/tex] be the reflection across the x-axis of the function [tex]f(x) = 7x + 3[/tex]. Identify the rule for [tex]g(x)[/tex].
So,
[tex]y = 7x + 3\\-y= 7x + 3\\y = - 7x - 3\\g(x)=- 7x - 3[/tex]
Hence, [tex]g(x) = - 7x - 3[/tex].

Ethan has $620 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $427.57. He buys 4 bicycle reflectors for $11.38 each and a pair of bike gloves for $31.41. He plans to spend some or all of the money he has left to buy new biking outfits for $57.75 each. Write and solve an inequality which can be used to determine oo, the number of outfits Ethan can purchase while staying within his budget.
Answers
Answer: 620≥ 427.57+ 11.38(4)+ (31.41) +57.75x
Step-by-step explanation:
So our limit is the 620$ that he has to spend. We know for a fact that the bike costs about 427.57 dollars. 4 $11.38 reflectors are purchased as well as gloves for 31.41. Now however many outfits he can purchase cannot exceed or go over his money limit of 620 so the variable (x) represents how many outfits he can buy without going over.
We are required to write an inequality for the problem and also solve it
The number of biking outfit Ethan can purchase is 2
Given:
Total amount Ethan has = $620
Amount of bicycle = $427.57
Bicycle reflector = $11.38
Cost of 4 Bicycle reflector = $11.38 × 4
= $45.52
Cost of bike glove = $31.41
Cost of biking outfit = $57.75
Write an inequality to solve for the number of biking outfit Ethan can purchase
let
x = number of biking outfit Ethan can purchase
620 ≥ 427.57 + 45.52 + 31.41 + 57.75x
620 ≥ 504.5 + 57.75x
620 - 504.5 ≥ 57.75x
115.5 ≥ 57.75x
x ≥ 115.5 / 57.75
x ≥ 2

1: 3x = 15
We divide 3 from both sides
X= 5
2: 2a + 5 = 25
Take the 5 to the other side the sign will be negative 25-5= 20
2a = 20
Divide both sides by 2a
You will get a= 10
