The credit remaining on a phone card (in dollars) is a linear function of the total calling time made with the card (in minutes). The remaining credit after 24 minutes of calls is $21.64, and the remaining credit after 35 minutes of calls is $20.10. What is the remaining credit after 45 minutes of calls?
Answer:
The remaining credit after 45 minutes of calls is $18.70
Step-by-step explanation:
Here, we have a linear model to work with
Let us have the coordinates as follows;
(time calling time, credit remaining)
So we have two points as follows;
(24,21.64) and (35,20.10)
The slope will be;
(20.1-21.64)/(35-24) = -1.54/11 = -0.14
So the equation looks like;
y = -0.14x + c
To get the y-intercept, we simply substitute a point
Let us use (35,20.10)
20.10 = -0.14(35) + c
c = 20.10 + 4.9
c = 25
So the full equation is;
y = -0.14x + 25
So for 45 minutes, simply substitute 45 for x
We have this as:
y = -0.14(45) + 25
y = -6.3 + 25 = $18.70
What is the intercept of the function f(x) = x^3
Answer:

y-intercept(s): ( 0 , 0 )
Explanation:
To find the x-intercept, substitute in 0 for y and solve for x .
To find the y-intercept, substitute in 0 for x and solve for y .

3w + 6 - 4w + 3b + 2 +2b=
The answer is 5b - w + 8
Step-by-step explanation:
Answer:
-w + 5b + 8
Step-by-step explanation:
Step 1: Since you're only dealing with addition and subtraction, the easiest method is to convert all subtraction to addition by adding the opposite. There is only one case of subtraction (-4w) which can be changed to adding negative 4w:
3w + 6 + (-4w) + 3b + 2 + 2b
Step 2: Combine like terms to simplify:
3w + (-4w) = -w
3b + 2b = 5b
6 + 2 = 8
Answer:
-w + 5b + 8

Step-by-step explanation:
Write an equation in point-slope form of the line that passes through the given points, then write the equation in slope-intercept form.
Answer:
(-3,5) (6,2) (Plug in these points into (y2-y1)/(x2-x1) to find the slope)
2-5/6-(-3)
-3/9
-1/3 is the slope
y - y1 = m(x -x1) (this is point slope form)
y - 5 = -1/3 (x +3) (you plug in the x &y values from the first set of coordinates)
y -5 = -1/3x -1 (you get to slope intercept form by solving from point slope)
y = -1/3x +4 (this is slope intercept form)
Step-by-step explanation:
What would y be? please show me how do to it also so I can understand.

What are the solutions to the quadratic equation 4(x + 2)2 = 36
x= -11 and x = 7
x = -7 and x = 11
OOOO
x= -5 and x = 1
x= -1 and x = 5
Answer:
x = -5 and x = 1
Step-by-step explanation:
4( x2 + 4x + 4 ) = 36
4x2 + 16x + 16 = 36
4x2 + 16x - 20 = 0
x2 + 4x - 5 = 0
Answer:
C. x = -5, and x = 1
Step-by-step explanation:
You have the equation 4(x + 2)2 = 36
You then isolate 4 out of the equation using division on both sides
You are left with (x+2)2 = 9
Next, take square roots
[tex]\sqrt({x} +2) ^{2}[/tex] = [tex]\sqrt{9}[/tex]
This leaves you with x + 2 ± 9
So, x = -2 + 3 = 1
or
x = -2 - 3 = -5
August is making dinner for 8 people. She opens 7 cans of soup. Each can is 16 ounces. If everyone gets the same amount of soup, how much soup will each person get?
This is for my sister, and her teacher said that the correct answer is 3.5 ounces. If anyone gets this answer, please show how you got the answer...thank you!
Answer:
14oz soup/ person
Step-by-step explanation:
the answer would be 14oz of soup/person
multiply 7 (cans of soup) by 16 (oz per can)
7*16=112
divide 112 (oz of soup total) by 8 (number of people feeding)
112/8=14

Find the distance from C to G.
Answer:
3/64
Step-by-step explanation:
The distance from C to G is 32 units and this can be determined by using the properties of the circumcenter of a triangle.
Given :
AG = 4x + 16
BG = 10x - 8
The following steps can be used in order to determine the distance from C to G:
Step 1 - Remember in the given diagram G is the circumcenter because all the perpendicular bisector intersects at point G.
Step 2 - Now, if G is the circumcenter then:
AG = BG = CG
Step 3 - Now, substitute the value of AG and BG in the above expression.
4x + 16 = 10x - 8
24 = 6x
x = 4
Step 4 - Now, use the relation BG = CG in order to determine the value of CG.
10(4) - 8 = CG
CG = 32

Cynthia invests some money in a bank which pays
5% compound interest per year.
She wants it to be worth over £8000 at the end of 3 years.
What is the smallest amount, to the nearest pound, she can invest?
Let ,Cynthia invested $x
Rate = 5%per year
time = 3 year
Amount
A= P(1+r/100)^t
8000=x(1+5/100)^3
8000=x(21/20)^3
x= (8000x8000)/9261
x=6910.7$
Therefore she can invest =$6910.7 =5322.14 pound
