Y=2/3x + 3

Y=__/__x + 5

Fill in the blanks

Answer: There are an infinite numbers of solutions. The only information given in the second equation is the y-intercept of y =5 where the second line crosses the y-axis. And there are an infinite number of lines crossing that point and also intersecting the first linear equation.

What is the equation in point−slope form of the line passing through (2, 2) and (4, 8)? A. (y − 2) = 3(x − 2)

B. (y + 2) = 3(x + 2)

C. (y − 8) = −3(x − 4)

D. (y + 8) = −3(x + 4)

Y-y1=m(x-x1)

that is equaton of a line passing through the point (x1,y1) and having a slope of m

find slope betweeen given points

slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)

given (2,2) and (4,8)

slope=(8-2)/(4-2)=6/2=3

a point is (2,2) or (4,8)

slope is m=3

so the equation is

y-2=3(x-2) or

y-8=3(x-4)

the answer is A

slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)

given (2,2) and (4,8)

slope=(8-2)/(4-2)=6/2=3

a point is (2,2) or (4,8)

slope is m=3

Look at the table showing different prices for oranges. Prices for Oranges

Price APrice BPrice C$2.25 for 6$1.30 for 4$0.97 for 2

Which gives the prices in order, from least to greatest unit rate?

Price B, Price A, Price CPrice C, Price B, Price APrice C, Price A, Price BPrice B, Price C, Price A

Answer:

1st Option is correct that is Price B , Price A , Price C

Step-by-step explanation:

Given:

Price A : Price of 6 oranges = $ 2.25

Price B : Price of 4 oranges = $ 1.30

Price C : Price of 2 oranges = $ 0.97

To find: Prices in increasing order that is from least to greatest unit rate.

First we unit rate of each price that is cost of 1 oranges in each price.

Price A : Price of 1 oranges =

Price B : Price of 1 oranges =

Price C : Price of 1 oranges =

So, Prices in Increasing order is as follows

0.33 < 038 < 0.49 ⇒ Price B < Price A < Price C

Therefore, 1st Option is correct that is Price B , Price A , Price C

2.25 for 6 would be 0.375 per one of them

1.30 for 4 would be 0.325 per one of them

0.97 for 2 would be 0.485 per one of them

1.30 for 4 would be 0.325 per one of them

0.97 for 2 would be 0.485 per one of them

Is the function linear or nonlinear? x −3 −1 0 1 3

y 9 1 0 1 9

A.

linear

B.

nonlinear

Linear functions form straight lines.

This is a parabola, and is not a straight line, therefore it is nonlinear.

This is a parabola, and is not a straight line, therefore it is nonlinear.

Answer:

Nonlinear

The outdoor temperature was 8 degrees at midnight. The tempature declined 5 degrees during each of the of the next 3 hours. What was the temperature at 3 am

Answer:

degrees.

Step-by-step explanation:

Let x represent number of hours.

We have been given that the outdoor temperature declined 5 degrees during each of the of the next 3 hours. So temperature decline in each hour would be .

The outdoor temperature at midnight was 8 degrees. The temperature x hours after midnight would be .

To find the temperature at 3 am, we will substitute in the expression as:

Therefore, the outdoor temperature was degrees at 3 am.

To do the math for this question, you would need to multiply the 5 degrees that it goes down each hour and multiply it by 3 hours to figure out how my degrees it has gone down in three hours. 5 degrees x 3 hours = 15 degrees in 3 hours Then you take the 8 degrees from midnight and subtract the 15 degrees to figure out what the temperature was at 3am. 8 - 15 = -7 degrees If I did the math correctly, the answer should be -7 degrees. Hope this helps!

MIDDLE SCHOOL

please help!!!!!!!!!!!!! which expression is equivalent to 3(2x+5).no matter what the value is substituted in for x.

You need the inverse operation

5 - 3=2

now you need multiply

2×3=6

so, X is 6

x=6

5 - 3=2

now you need multiply

2×3=6

so, X is 6

x=6

Which equation is y = –6x2 + 3x + 2 rewritten in vertex form?

Y = -6x^2 + 3x + 2

y = -6(x^2 - 0.5x) + 2

y = -6[ (x - 0.25)^2 - 0.0625] + 2

y = -6(x - 0.25)^2 + 2.375 Answer

y = -6(x^2 - 0.5x) + 2

y = -6[ (x - 0.25)^2 - 0.0625] + 2

y = -6(x - 0.25)^2 + 2.375 Answer

Answer:

c
