Mathematics
1 answer:
Ostrovityanka [42]3 years ago
4 0

Answer:

Step-by-step explanation:

1. y - 2 = -3(x - 4)

  y - 2 = -3x + 12

  y = -3x + 14

2. y - 6 = -1/2(x + 5)

   y - 6 = -1/2x - 5/2

   y - 12/2= -1/2x - 5/2

   y = -1/2x + 7/2

Help im brain dead or im just dumb

Answer:

2

Step-by-step explanation:

There are four giraffes that equal 32. That means the four of them equal 32, and since they are all giraffes, they are the same amount.

32/4 = 8

Girrafe = 8

Two tigers times a giraffe equals 32. We already know that a girrafe equals 8.

32/8 = 4.

Therefore the two tigers equal 4. Since there are two tigers, and they equal 4, each tiger equals 2.

Now we know girrafes equal 8, and tigers equal 2.

A girrafe - A tiger x 3 = 2

PEMDAS says that you multiply first. So 2 x 3 equals 6. Take away 6 from 8 and you get 2.

The blueprint of a pool has a scale of 2 inches equals 7 feet. The scale drawing is shown below. the length is 20 and the width
AlladinOne [14]

Answer:

Part A:

Blueprint 10 inches ⇒ Actual 35 feet

Blueprint 20 inches ⇒ Actual 70 feet

Part B:

The cost of the cover is $857.5

Step-by-step explanation:

Part A:

∵ The drawing scale is 2 inches for 7 feet

∵ The length = 20 inches and the width = 10 inches

∴ The actual length = (20 × 7) ÷ 2 = 70 feet

∴ The actual width = (10 × 7) ÷ 2 = 35 feet

Part B:

∵ The cost per square foot = $0.35

∵ The area of the pool = 70 × 35 = 2450 feet ²

∴ The cost of the cover = 2450 × 0.35 = $857.5
