Answers

Answer 1

Answer:

b. y=-2x+3

Step-by-step explanation:

find slope by getting any 2 points form the graph

(0,3) (1,1)

m = (y2-y1) / (x2-x1)

m = (1-3) / (1-0) = -2 it means by moving one unit right you need to move 2 unit down

note that it does not matter which points you chose to be second or first

then use slope point equation again it does not matter which point from the slope you use

y - y1 = m ( x - x1 )

y - 3 = -2 ( x - 0)

y = -2x +3

Answer 2

a) 2x+3

Step-by-step explanation:

The line passes throught the point (1;1) and (0;3)

gradient(m) =change in y ÷ change in x

=y1-y2 ÷x1-x2

=1-3 ÷ 1-0

=-2

therefore m is -2.

y-y1=m(x-x1)

y-1=-2(x-1)

y=2x+2+1

y=2x+3

Michael has a points card for a movie theater.

He receives 35 reward points just for signing up.

He earns 2.5 points for each visit to the movie theater.

He needs 70 points for a free movie ticket.


Write and solve an equation that can be used to determine v, the number of visits Michael must make to earn a free movie ticket.

Answers

Let the number of visits equal x.

Multiply the number of points by the points per visit.

2.5x

Add that to the points he got for signing up:

2.5x + 35

This needs to equal the total points needed:

2.5x + 35 = 70

Solve for x:

Subtract 35 from both sides:

2.5x = 35

Divide both sides by 2.5:

X = 14

He needs 14 visits

He needs 14 total visits to get to 70

Answer:

[tex]54\:\mathrm{km/h}[/tex]

Step-by-step explanation:

Average speed is given by [tex]S=\frac{d}{t}[/tex], where [tex]d[/tex] is distance and [tex]t[/tex] is elapsed time.

Since we want the average speed of the entire trip, we need to total distance of the entire trip and the total time it takes for the entire trip.

What we know:

The trip took 2 hours (2:30 PM to 4:30 PM)The bus travelled [tex]22.5+42.8+42.7=108[/tex] kilometers

Substituting known values, we get:

[tex]S_{avg}=\frac{108\:\mathrm{km}}{2\:\mathrm{h}}=\boxed{54\:\mathrm{km/h}}[/tex]

the solution should be 54km/h if you use s=d/t

F. 5 2/5 ÷ 1/3= ?

Answers

Honestly, I'm not sure how to answer this, but I think this can help you.

Well if 5 and 2 fifths is one third of the total height of the building, then that means to find the total height of the building you need to times 5 2/5 by 3.

(I think F is an answer)

The answer is E, they use the formula 5 2/5 x 3/1 which means that they need 3 wholes of the original 5 2/5.

What is the surface area of a pyramid with a base area of 25 ft2 and lateral faces each with areas of 15 ft2?

Answer:

85 ft^2

Step-by-step explanation:

Ok, the square base area is 5 x 5 = 25 square feet

the triangular sides have an area of (1/2)(5)(6) each, which is 15 square feet each, like you said.

To find the total surface area, you multiply the 15 square feet x 4 (there are 4 sides) and add the base.

15 x 4 = 60 + 25 = 85 square feet
