Eli needs pieces of ribbon cut into strips that are 2 1/2 feet long. The roll of ribbon is 7 1/2 feet long. Which expression cou

Lady bird [3.3K]

3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Step-by-step explanation:

Length of strips Eli need is 2.5 feet long

Length of roll of ribbon is 7.5 feet long

Number of strips that can be cut from the 7.5 feet long roll is x

<u>SOLUTION:</u>

To determine how many strips can be cut, divide total length of roll of ribbon by the length of strips needed.

Number of strips that can be cut = $\frac{Total Length of roll}{Length of strips needed}$

x = $\frac{7.5}{2.5}$ (expression)

x = 3 strips

Therefore, 3 strips of 2.5 feet can be cut from the 7.5 feet long roll of ribbon.

Marco was shopping for markers and lead pencils. The cost of markers is $4, and the cost of each lead pencil is $3. If Macro can

never [62]

This shows that Marco can buy at most 5 pencils

<h3>Inequalities</h3>

Let the price of each pencil Marco can buy be "x"

If the cost of markers is $4, and the cost of each lead pencil is $3 with at most $15 spent, hence;

4 + 3x ≤ 15

Subtract 4 from both sides

3x ≤ 15

x ≤ 15/3

x ≤ 5

This shows that Marco can buy at most 5 pencils

What is the slope of the line through (-7,-8)(−7,−8)left parenthesis, minus, 7, comma, minus, 8, right parenthesis and (0,4)(0,4

ANEK [815]

Answer:

12/7

Step-by-step explanation:

When given two points, we can find the slope by using

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

= (4 - -8)/ (0 - -7)

= (4+8) / (0+7)

= 12/7

The scatter plot shows the study times and test scores for a number of students. How long did the person who scored 81 study?

Free_Kalibri [48]

Answer: Option A

50 minutes

Step-by-step explanation:

Observe in the diagram that the vertical axis represents the score obtained and the horizontal axis represents the study time.

To find out how many hours the person with a score of 81 studied, locate the point that is at a vertical distance of 81.

Now draw a vertical line from this point to the horizontal axis. Note that the vertical line traced intercepts the vertical axis at x= 50

Then the person who got a score of 81 studied 50 minutes

The answer is the option A

Answer:

$(x,y) =(-4,-3)$ --- Vertex

$x = -4$ --- Axis of symmetry

Step-by-step explanation:

Given

$y = -6(x + 4)^2 - 3$

Solving (a): The vertex

For an equation written in

$y = a(x - h)^2 + k$

The vertex is:

$(x,y) = (h,k)$

By comparison:

$y = a(x - h)^2 + k$ and $y = -6(x + 4)^2 - 3$

$-h =4$ $k = -3$

$h =-4$ $k = -3$

So, the vertex is:

$(x,y) =(-4,-3)$

Solving (b): The axis of symmetry

For an equation written in

$y = a(x - h)^2 + k$

The axis of symmetry is:

x = h

In (a):

$h =-4$

So:

$x = -4$
