Answers

Answer:

Step-by-step explanation:

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4 Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is 2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that

Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them

Make sure to label each line

Driving 65 mph, it takes Alicia 3 hours to reach the airport to go on a vacation. It then takes her 4 hours to get to her destination with the jet traveling at a speed of 450 mph. How many miles does Alicia travel to get to her destination?

Answers

Answer: i am the first one to answer please mark brainliest

65x3 + 450x4=

Step-by-step explanation:

195+1800=1995

Answer:

1,955 miles

Step-by-step explanation:

For this problem all we have to do is, assuming they were constantly going that speed and never stopped, multiply the items and the mph.

SO, to the airport is 65mph*3 hours, which would give 195 miles.

Then, To their destination, 450mph * 4hours = 1,800 miles

Now all that is left to do is add

195 + 1,800 = 1,995

1,995 miles

Write and solve an equation to show the answer.

Explain when to use division and when to use multiplication to solve an equation. Give examples to support your answer

Answers

Answer: 1,796

Step-by-step explanation:

We are given that : At the chicken ranch this morning there were 7,149 chicks.

i.e. The number of new chicks before today = 7,149

Later today some more chicks hatched. now the ranch has 8,945 chicks.

i.e. The number of new chicks after today = 8,945

Then, By Subtraction operation

Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )

= 8,945- 7,149 = 1,796

Therefore , the number of new chicks hatched today = 1,796
