Concept: Graph Analysis

Take a look at the first graph. Notice it goes through (0,-2) and the slope is 5/2 so the answer is A.Next to find the equation we look at the y-intercept and determine that its -2 and the slope is -5/2. Hence the answer is C

Step-by-step explanation:

Problem 1.

Start at (0, -2). Go up 5 and right 2. That is a slope of 5/2.

First choice.

Problem 2.

The y-intercept is (0, -2), so b = -2.

Start at (0, -2). Go down 5 and right 2. That is a slope of -5/2.

y = mx + b

y = -5/2 x - 2

Answers

Answer:

6:4 or 3:2

6/10 are consonants

40%

Step-by-step explanation:

A) count the numbers of consonants and vowels. There are 6 consonants and 4 vowels so the ration is 6:4. If you're simplifying, you divide both sides by 2 to get 3:2

B) Count the total letters. There are 6 consonants and 10 total letters so the fraction is 6/10 because 6 put of 10 are consonants.

C) 4. x

- = 10x = 4(100)

10. 100. 10x = 400

- -

10. 10

x= 40

You divide 10 by 10 to get x alone and then divide 400 by ten.

The water park is a popular field trip destination. This year the senior class at high school a and high school b both planned trips there. The senior class at high school a rented filled 4 vans and 14 buses with 742 students. High school b rented and filled 4 vans and 6 buses with 350 students. Each van and each bus carried the same number of students. Find the number of students in each van and in each bus.

Answers

so let’s start of by setting variables for buses and vans
x = buses
y = vans

our equations will look something like this :

4x + 14y = 742 &’
4x + 6y = 350

let’s solve for y first . we need to cancel out our x’s so we turn on of them into a negative and since both of them have the same common factor we don’t need to find it . let’s multiply the bottom equation by ( -1 )

here’s what our new equations look like :
4x + 14y = 742
-4x - 6y = -350

now that our x’s are cancelled out we add our y’s and our totals :

14y + ( -6y ) = 8y
742 + ( -350 ) = 392

we want y alone so we divide :

392/8 = 49

y = 49

now we can substitute 49 for y :

4x + 14 ( 49 ) = 742
4x + 6 ( 49 ) = 350

we can multiply those numbers together :

4x + 686 = 742
4x + 294 = 350

now we add downward :

8x + 980 = 1,092

we need x alone so we subtract 980 from both sides :

8x = 112

divide by 8 :

x = 14

now , we can substitute 14 for x and 49 for y to check our work :

4 ( 14 ) + 14 ( 49 ) = 742

742 = 742 ✅

4 ( 14 ) + 6 ( 49 ) = 350

350 = 350 ✅

The sum of two numbers is 14 and their difference is 18. Find the larger number.

Answers

Answer:

Let a = the larger number and b = the smaller

a + b = 14

a - b = 18

We can add the 2 equations together.

2a = 32

2a/2 = 32/2

a = 16

The answer is 16
Because a = the larger number and b = the smaller number so equations would look like a+b=14 and a-b=18 we can add the 2 equations together and get 2a=32 then simply to 2a/2=32/2 then simplify that and get the answer a=16

he paid $12 because the original price was marked down.
