Answer:

1. y=3x+3

2. y=3x+1

Step-by-step explanation:

Use y=mx+b

Sub (0,3) into y=mx+b

3=m(0)+b

b=3

Sub (3,9) into y=mx+3

9=m(3)+3

3m=6

m=2

EQUATION: y=3x+3

Sub (1,4) into y=mx+b

4=m(1)+b

b=4-m

Sub (3,10) into y=mx+(4-m)

10=3m+4-m

2m=6

m=3

b=4-m=4-3=1

EQUATION:y=3x+1

Base your answer on Betty is thinking of two consecutive integers whose sum is 41.

mel-nik [20]

Answer:

let the numbers be, x and x+1 ( as it is consecutive number the next number will have 1 more than the number )

sum = 41

so, x + ( x + 1 ) = 41

x + x + 1 = 41

2x + 1 = 41

2x = 41 -1 = 40

2x = 40

x = 40/2 = 20

x = 20

x + 1 = 20 + 1 = 21

so the consecutive numbers whose sum is 40 are, 20 and 21

hope this answer helps you.....

There were 178 old cars at the junkyard. Then a truck brought in some more cars. Now there are a total of 236 cars in the junkya

crimeas [40]

Answer:

The correct answer is 58 cars.

Step-by-step explanation:

Cars in the junkyard before the truck arrived with some = 178

Cars after the truck brought into the junkyard some more= 236

Cars brought in by the truck = 236 - 178

Cars brought into the junkyard by the truck = 58

The number of cars brought by the truck is 58 cars.
