Answer:

Answer:

$31.70

Step-by-step explanation:

In order to find the total monthly charge for the customer, you can set up an equation using two different variables and putting in the charges and number of calls for each.

Let 'x' = the number of in-state calls and 'y' = the number of out-of-state calls.

Equation: 0.03x + 0.11y + 10.75 = total

Since the customer made 350 minutes of in-state calls, x = 350 and 95 minutes of out-of-state calls, y = 95:

0.03(350) + 0.11(95) + 10.75 = total

$10.50 + $10.45 + $10.75 = $31.70

HIGH SCHOOL

You had $235 in your savings account nine weeks ago. You withdrew the same amount each week for 8 straight weeks. Your balence was then $75. Solve the equation 235 - 8m=75 to find how much money m you withdrew from your account each week. 2 points

$20

235-75=160

160÷8=20

Point F is on circle C. What is the length of line segment GF?

12.5 units

15.0 units

17.5 units

20.0 units

We know that : GF = GC + CF.Also, CF is a radius. So CF = 7.5 unitsTo find GC we will use the Pythagorean theorem.GC² = 10² + 7.5²GC² = 100 + 56.25GC² = 156.25GC = √ 156.25GC = 12.5GF = 12.5 + 7.5 = 20Answer: d. 20 units.

Answer:

20.0 units

Step-by-step explanation:Line segment CF is congruent to CE, so CF also equals 7.5

Use the pythagoran theorem to find the measure of GC

Now that we know GC has a measure of 12.5, we can add it with CF

12.5+7.5= 20.0

Therefore The Answer Is D.)20.0

A parabola can be represented by the equation y2=5x

Yes, a parabola can be represented by the equation

How to define a parabola with all its properties -In mathematics, a parabola is a plane curve which is mirror-symmetrical and is approximately U-shaped.

The general equation of a parabola is where x and y are the x and the y intercepts and a is the distance of the focus from the vertex of the parabola.

The latus rectum of parabola is defined as the line segment passing through its focus and perpendicular to its axis.

For the given parabola,

Vertex : (0,0)

Focus : (5/4, 0)

Axes of symmetry : y = 0

Directrix : x = - 5/4

Length of latus rectum : 5 units

Thus the parabola can be formed and so can be plotted in the graph.

Corresponding sides of similar triangles are proportional?

Yes that's right - that means that if you take one triangle and multiply all its sides by the SAME factor, you'll end up with the other triangle. It's the same shape, just a different size.

Solve for x in equation

x-c/2=d

X-c/2 = d

Multiply by 2 on both sides. Leaves us with:

x-c = 2d

Add 2 to both sides. Leaves us with:

x = 2d + c

Unless you have values to substitute into the variables, this is your answer:

x = 2d + c

Multiply by 2 on both sides. Leaves us with:

x-c = 2d

Add 2 to both sides. Leaves us with:

x = 2d + c

Unless you have values to substitute into the variables, this is your answer:

x = 2d + c

10 - x = 2(-2x - 4)

Identify with either No Solution or All Real Numbers.

Answer:

-6 (All Real Numbers)

Step-by-step explanation:

First, you need to solve it and then determine if it is a solution or not. -6 is an integer, making it a real number. Therefore, the answer is "All Real Numbers".

Hope this helps! :-)

Answer:

Step-by-step explanation:

Isolate x on one side of the equation.

2(-2x-4) ← (Expand by using with distributive property.)

DISTRIBUTIVE PROPERTY

⇒ A(B+C)=AB+AC

⇒ A(B-C)=AB-AC

A=2

B=(-2x)

C=4

2(-2x)-2*4

-2*2x-2*4

-2*2x-2*4 (Solve.)

-2*2-2*4=-4x-8

Rewrite the equation problem.

10-x=-4x-8

10-x-10=-4x-8-10 (Subtract 10 from both sides.)

Solve.

-x=-4x-18

-x+4x=-4x-18+4x (Then, add 4x from both sides.)

3x=-18 (Solve.)

3x/3=-18/3 (Divide by 3 from both sides.)

-18/3 (Solve & Simplify.)

-18/3=-6

X=-6

Therefore, the correct answer is x=-6.

Find the limit of the function algebraically (with cancellation techniques and direct substitution, that is, since this is in indeterminate form):

------

It seems to have a dividing by zero issue from what I have managed to get out of the problem... That or I am having trouble discerning how to break it down into a manageable 0 issue. Help would be greatly appreciated, or at the very least a confirmation that I have the correct answer in that there is no limit.

At x=0, the numerator is positive and the denominator is zero. The form is not "indeterminate", but is "undefined". The limit is the same (+∞) whether approaching zero from the left or the right, so we say

the limit is +∞

_____

The case of "no limit" is reserved for those conditions in which the value you get approching from the left is different from that approaching from the right and/or is different from the defined value of the function at the point.

For example, 1/x has no limit at x=0 because it approaches -∞ from the left and +∞ from the right.

the limit is +∞
