Answers

Answer:

y-int:(0,-2)

slope: 5/2

Step-by-step explanation:

slope is rise over run, so you just need to find 2 points (0,-2) and (2,3) and calculate (3-(-2))/(2-0) and get 5/2. y intercept is just the point located at X=0

Answer:

The y-intercept is (0, -2) and the slope is 5/2

Jane loves animals. She has an equal number of beetles, birds and spiders as pets. Apart from human legs, there is a total of 270 legs in the house. How many spiders dies jane have if a spiders has 8 legs and a beetle has 6 legs?​

Answers

b = number of beetles

r = number of birds

s = number of spiders

"She has an equal number of beetles, birds and spiders". That means b = r = s. They all stand in for the same number, and that number being some positive whole number.

One spider has 8 legs, so s of them have 8s legs. One beetle has 6 legs, so b of them have 6b legs. One bird has 2 legs, so r birds have 2r legs.

In total, all of the animals have 6b+2r+8s legs. We'll replace r and s with b, since earlier we were given that b = r = s.

So we end up with:

6b+2r+8s

6b+2b+8b

(6+2+8)b

16b

The number of legs of all the animals is equal to 16 times the number of beetles. Set this equal to 270 and isolate b

16b = 270

b = 270/16

b = 16.875

We run into a problem. It's not possible to have the variable b equal to a non-whole decimal number like this. It's possible your teacher made a typo somewhere. I would ask them for clarification.

Find the amount of tax and the tax rate. Round to nearest hundredth of a percent . Cost of item: $118 Selling price: $132.37 Tax Amount: $ Tax Rate percentage%​

Answers

Answer:

The amount of tax is $14.37 and the tax rate percentage is 12.18%

Step-by-step explanation:

Find the amount of tax by finding the difference between the cost and selling price:

132.37 - 118

= 14.37

Find the tax rate percentage by dividing the tax by the original cost, and multiplying it by 100:

(14.37/118) x 100

= 12.18

The amount of tax is $14.37 and the tax rate percentage is 12.18%

Answers

Step-by-step explanation:

B.

AC =BC

2x-6=x+8

2x-x=8+6

x=14

5) AC = 2x-6=2(14)-6=28-6= 22

6) BC = x+8= 14+8= 22

7) AB = AC+BC = 22+22= 44

C.

AC =BC

4x+10=7x-5

4x-7x= -5-10

-3x= -15

x= -15/-3 = 5

8) AC = 4x+10=4(5) +10=20+10= 30

9) BC = 7x-5= 7(5) -5=35-5= 30

10) AB = AC+BC = 30+30= 60

B) Solution

AC = BC

→ 2x-6 = x+8

→ 2x-x = 8+6

→ x = 14

5:- AC = 2x-6 = 2(14)-6 = 28-6 = 22

6:- BC = x+8 = 14+8 = 22

7:- AB = AC+BC = 22+22 = 44

C) Solution

AC = BC

→ 4x+10 = 7x-5

→ 4x-7x = -5-10

→ -3x = -15

→ x = -15/-3

→ x = 5

8:- AC = 4x+10 = 4(5) +10 = 20+10 = 30

9:- BC = 7x-5 = 7(5)-5 = 35-5 = 30

10:- AB = AC+BC = 30+30 = 60

Answer:

New volume will become 187.5 inch²

Step-by-step explanation:

Initial volume,

V = lbh

Put all the values,

V = 6.25 × 2.5 × 6

V = 93.75 inch³

When the length is doubled, l' = 2(6) = 12 inch

New volume,

V' = 12 × 6.25 × 2.5

= 187.5 inch²

So, when the length is doubled, the new volume will become 187.5 inch².

1. Which expression represents the
factored form of x2 - 13x + 36?
A (x - 4)(x - 9)
B (x - 3)(x - 12)
C (x + 9)x - 4)
D (x + 12)(x - 3)

Answers

Answer: Hello, There! your Answer is Below

A (x - 4)(x - 9)

Step-by-step explanation:

Find p, and q, knowing sum = b = 13 and product c = 36. Compose factor pairs of 36-> (2, 18)(2, 12)(4, 9). this last sum is 9 = b. Then p = 4 and q = 9

Hope this Helps you!!

Have a great day!!

The answer is choice A. The middle number, the one with the x, in this case 13, is what the factors should add up to. so, -4 plus -9 equals -13, which is our middle number. the last number, without the x, is what the numbers must multiply to, in this case 36. so, -4 times -9 equals positive 36. So, choice A is the answer.
