Answer:

  y = -4x +9

Step-by-step explanation:

The same slope-intercept equation can be used, but with a different y-intercept. That new y-intercept can be found from the given point (x, y) using the formula ...

  b = y -mx

  b = 5 -(-4)(1) = 9

So, the equation with the new y-intercept is ...

  y = -4x +9

Answer:

140.74

Step-by-step explanation:

1.area of right triangle

1/2*b*h=1/2*20*18=180

2.area of semi circle

1/2*pi*r^2=1/2*pi*5^2=39.26

r= d/2

180-39.26=140.74

first you find the area of the half circle cut out. area of circle is pi*radius² ; therefore the area of half of the circle is that equation divided by two. you get around 39 for the area of the half circle or 25pi/2. then find the area of the triange which is 1/2(base)(height) or 1/2(18)(20)=180

then do 180-(25pi/2) which equals to about 140.73009

There are 2 rectangles. One was 1.2 cm by 3.4 cm. The other was measured 2.1 cm by 1.7 cm. How much is the perimeter?

Answers

Answer: See explanation

Step-by-step explanation:

Perimeter of a rectangle is given as:

= 2(length + breadth)

First rectangle measures 1.2 cm by 3.4 cm. The perimeter will be:

= 2(1.2+ 3.4)

= 2(4.6)

= 2 × 4.6

= 9.2cm

Second rectangle measured 2.1 cm by 1.7 cm. The perimeter will be:

= 2(2.1 + 1.7)

= 2 × 3.8

= 7.6cm

Total perimeter = 9.2cm + 7.6cm = 16.8cm

(40 POINTS) Let x = price of a standard ticket, y = price of a matinee ticket, and z = price of a senior ticket.

150x + 80y + 12z = 2,466
380x + 95y + 48z = 5,419
210x + 130y + 60z = 3,960

220x + 225y = 4,445
540x + 270y = 8,370 → y = −2x + 31

x = 11

The solutions to the system mean:

A.) Eleven tickets were sold on Friday. Nine tickets were sold on Saturday. Eight tickets were sold on Sunday.

B.) Eleven standard tickets were sold. Nine matinee tickets were sold. Eight senior tickets were sold.

Each wallet contained the name and address of the owner and either a photograph of a baby, a photograph of a puppy, a photograph of a young family, a photograph of an older couple, or no photograph. The researchers hypothesized that the type of photograph left in the wallet would influence the rate of return. The wallets with a photograph of the baby and the wallets with a photograph of the puppy were left early in the morning, the wallets with a photograph of the young family were left in the afternoon, and the wallets with either no photograph or a photograph of an older couple were left in the evening. Eighty-four of the 200 wallets (42%) were eventually mailed back to the owner, as shown below.Type of PhotographBabyPuppyYoung familyNo photographOlder coupleReturn Rate80%65%47%10%5%A.
