Please help me find the answer! Please explain how you got it!

Ksenya-84 [330]

Answer:

B. 4.5c + 4 = 24

Step-by-step explanation:

T = cx + py is the equation you are given.

T = 24 because it is the total amount of money you can spend.

x = 4.5 because each phone case costs 4.50 dollars

p = 2 because you bought 2 pop sockets.

y = 2 because each pop socket costs 2 dollars.

There is no c because you don't know the number of phone cases you bought.

Now, we have to substitute the values into the equation:

24 = 4.5x + 2(2)

24 = 4.5x + 4

4.5x + 4 = 24 <--- This is your answer

Hope this helps!

Use the graphs below to help you answer the question. Which of the following is the best approximation to a solution of the equa

brilliants [131]

Answer:

2 is the correct option.

Step-by-step explanation:

We have the equation $e^x=4x+1$ .

We will plot the graphs of the function $e^x$ and $4x+1$ .

Then, the intersection points of both the graph will be the solution of the equation $e^x=4x+1$ .

From the graphs, we see that,

The intersection points of the graphs are (0,1) and (2.337,10.347).

The solution of the equation is the value of 'x' co-ordinate where they intersect.

So, we get, x = 2 is the correct option.

By counting grid squares, we see the library is 5 miles north and 6 miles east of Ashley's house. Using the Pythagorean theorem, we can find the straight-line distance to be

Area of triangle with following verticies (0,-9), (3,-9), and (0,-2)

Neporo4naja [7]

Answer:

Area = 21/2 = 10.5 area units

Step-by-step explanation:

Two of the points are on the same line (the y-axis) as they both have x-coordinates of 0. This can thus be the base of your triangle.

Two more are on the same line (y= -9) as they both have the same y-coordinate of -9. This can be the height of your triangle.

So you have a base which is between -2 and -9 (7 units) and a height which is between 0 and 3 (3 units) so now just use the equation for area of a triangle $A=0.5*b*h$
