Answer: $19.6
Step-by-step explanation:
Linear function: f(x)=mx+c
, where m= rate of change in f(x) with respect to x.
c = Initial value.
Let c = Initial value of card , m= Charge per minute
x= Number of minutes calling time.
Then, 25.06= 38m+c (i)
21.03=69m+c (ii)
Eliminate (ii) from (i)
[tex]4.03=-31m\\\\\Rightarrow\ m=\dfrac{4.03}{-31}\\\\\Rightarrow\ m=-0.13[/tex]
Put m in (i) , we get
[tex]25.06= 38(-0.13)+c\\\\\Rightarrow\ 25.06=-4.94+c\\\\\Rightarrow\ c=25.06+4.94\\\\\Rightarrow\ c=30[/tex]
i.e. f(x)=-0.13x+30
if x=80 then
f(80)= -0.13(80)+30
=-10.4+30
=19.6
Hence, the remaining credit after 80 minutes of calls = $19.6
Simplify the expression

Step-by-step explanation:
The school production of 'Our Town' was a big success. For opening night, 391 tickets were sold. Students paid $4.00 each, while non-students paid $6.00 each. If a total of $1786 was collected, how many students and how many non-students attended?
Answer:
280 students
111 non students
Step-by-step explanation:
number of students (S)
number of non students (N)
S+N=391 S=391-N
4S+6N=1786
substitute S
4(391-N)+6N=1786
1564-4N+6N=1786
subtract 1564 from each side
2N=222
N=111
S=391-111=280

(1) One apple weighs 75 grams and one orange weighs 40 grams. The weight of x apples and y oranges, is
Answer:
Given,
Weight of each apple =75 gm
Weight of each orange =40 gm
So,
Weight of x apples =75x gm
Weight of y oranges =40y gm
Thus,
Weight of x apples and y oranges =(75x+40y) gm

Calculate the area of the trapezoid
Answer:
180 in^2
Step-by-step explanation:
area = 5(sq rt 75) x (sq rt 27) - [5(sq rt 75)-5(sq rt 27)] x 3(sq rt 3) x 0.5
area = 180 in^2

Find the value of x in the following figure.
Answer:
x = 8
Step-by-step explanation:
180-(89+57)= 180-146 = 34
(5x -6) = 34
5x = 34 + 6
5x = 40
x = 40 ÷ 5
x = 8

Answer:
y = 4
x = 5
y = 2
x = 1
x = 8
Step-by-step explanation:
to find y-intercepts, set x = 0
to find x-intercepts, set y = 0
1.) 4(0) + 5y = 20
5y = 20
y = 4 -------> y-intercept
2.) 4x + 5(0) = 20
4x = 20
x = 5 -------> x-intercept
3.) 2(0) + y = 2
y = 2 -------> y-intercept
4.) 2x + 0 = 2
x = 1 -------> x-intercept
5.) x - 2(0) = 8
x = 8 -------> x-intercept
Answer:
4x+5y=20 the answer is below
x= −5/4y+5
y= −4/5x+4
2x+y=2 the answer is below
x= −1/2y+1
y=−2x+2
x-2y=8 the answer is below
x=2y+8
y=1/2x−4
Step-by-step explanation:
Let's solve for x.
4x+5y=20
Step 1: Add -5y to both sides.
4x+5y+−5y=20+−5y
4x=−5y+20
Step 2: Divide both sides by 4.
4x/4 = −5y+20/4
x= −5/4y+5
Answer:
x= −5/4y+5
Let's solve for y.
4x+5y=20
Step 1: Add -4x to both sides.
4x+5y+−4x=20+−4x
5y=−4x+20
Step 2: Divide both sides by 5.
5y/5 = −4x+20/5
y= −4/5x+4
Answer:
y= −4/5x+4
Let's solve for x.
2x+y=2
Step 1: Add -y to both sides.
2x+y+−y=2+−y
2x=−y+2
Step 2: Divide both sides by 2.
2x/2= −y+2/2
x= −1/2y+1
Answer:
x= −1/2y+1
Let's solve for y.
2x+y=2
Step 1: Add -2x to both sides.
2x+y+ −2x=2+ −2x
y=−2x+2
Answer:
y=−2x+2
Let's solve for x.
x−2y=8
Step 1: Add 2y to both sides.
x−2y+2y=8+2y
x=2y+8
Answer:
x=2y+8
Let's solve for y.
x−2y=8
Step 1: Add -x to both sides.
x−2y+−x=8+−x
−2y=−x+8
Step 2: Divide both sides by -2.
−2y −2=−x+8−2
y=1/2x−4
Answer:
y=1/2x−4

Please help I don’t wanna add a bunch of points Bc nobody is helping me I’m just wasting them.
You want to determine the height of your
school building. The building casts a 6-foot
shadow at the same time you cast a 15-inch
shadow. If you are 5 feet tall, how tall is the
school building? Write an equation and solve,
showing ALL the work.
Answer:Cross multiply and solve for x.
x/6 = 5/1.25
let the height of building be h ft
h/6 = 60/15
h = 6(60/15) = 24
the building is 24 ft high
Step-by-step explanation:
Well first let’s covert the ft to in- 5ft is 60 in and 6ft is 72 in. Then we want to set up 2 fractions based on height and shadow, so we have 60/15=x/72 (we put x because that’s what we’re trying to find). Then we do cross multiplication so now we have 15x=4320. We divide 15, so now we have 4320/15=288. So the building is 288 in tall or 24ft tall! Glad to help! :)
