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

The set of side lengths that could represent a right triangle is
12 ft, 10 ft, and 8 ft.
Option D is the correct answer.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
To determine which of the given sets of side lengths could represent a right triangle, we can apply the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).
Using this theorem, we can check each of the given sets of side lengths to see if they satisfy this condition:
6 ft, 5 ft, 4 ft
6² + 5² = 36 + 25 = 61
4² = 16
Since 61 is not equal to 16, this set of side lengths does not represent a right triangle.
8 ft, 7 ft, 6 ft
8^2 + 7^2 = 64 + 49 = 113
6^2 = 36
Since 113 is not equal to 36, this set of side lengths does not represent a right triangle.
10 ft, 8 ft, 6 ft
10^2 + 8^2 = 100 + 64 = 164
6^2 = 36
Since 164 is not equal to 36, this set of side lengths does not represent a right triangle.
12 ft, 10 ft, 8 ft
12^2 + 10^2 = 144 + 100 = 244
8^2 = 64
Since 244 is equal to 64 + 180, this set of side lengths does represent a right triangle.
Therefore,
The set of side lengths that could represent a right triangle is 12 ft, 10 ft, and 8 ft.

Solve the equation, and choose the type of solution you
found.
2x + 8 = 2(x + 4)
Answer:
All real numbers are solutions
Step-by-step explanation:
2x + 8 = 2(x + 4)
~Simplify right side
2x + 8 = 2x + 8
~Subtract 8 to both sides
2x = 2x
~Divide 2 to both sides
0 = 0
Best of Luck!
Answer: the answer is infinite
Step-by-step explanation: so first you need to distribute the 2 into the () and you would get 2x+8 and since it is the same on both sides it cancles eachother out therefore there is infinite answers

Jazzy goes to bed 3 h after dinner.
Yesterday, she spent 1 1/2 h on her homework and 2/3 h on the telephone after dinner.
How much time does she have before bed time?
PLEASE SHOW YOUR WORK!!!
Answer:
It was easy
Step-by-step explanation:
11 x 2 = 22
3 x 2 = 6
22 x 6 = 132
The time Jazzy has before going to bed is [tex]\frac{5}{6}[/tex] hour
The first step to take in determining the answer is to add the hours she spent on various activities she did after dinner
Sum of activities done after dinner = hours spent on homework + hours spent on the telephone
[tex]1\frac{1}{2}[/tex] + [tex]\frac{2}{3}[/tex]
[tex]1\frac{3 + 4}{6}[/tex]
= [tex]1\frac{7}{6}[/tex]
=[tex]2\frac{1}{6}[/tex] hours
Th second step is to subtract the total hours Jazzy spent on activities from the hours Jazzy has before going to bed after dinner
Time left before she goes to bed = time she has to go to bed after dinner - total hours spent before going to bed
3 - [tex]2\frac{1}{6}[/tex] hours = [tex]\frac{5}{6}[/tex] hour

The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Boise, Idaho, and Reno, Nevada, is 430 miles. Express the distance in kilometers.
A.
431.6 km
B.
268.8 km
C.
688 km
Answer: C) 688 km
=================================================
Work Shown:
k = 1.6d
k = 1.6*430
k = 688
430 miles is roughly equivalent to 688 km.
More accurately, 430 miles = 692.01792 km, so this approximation isn't too far off.
Answer: the answer is C. 688 km
RESULT
The distance between Boise, Idaho and Reno, Nevada is 688 kilometers.
Step-by-step explanation:
The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. Express each distance in kilometers. the 430 miles between Boise, Idaho, and Reno, Nevada
k = 1.6 d
Where k is in kilometers n d in miles
The distance between Boise, Idaho and Reno, Nevada is 430
Substituting d= 430 we get,
k = 1.6(430)
k = 688
RESULT
The distance between Boise, Idaho and Reno, Nevada is 688 kilometers.

2. Which of the following are solutions to - 2.7 + x = - 3.5?
Step-by-step explanation:
x = -4/5 = -0.8
Answer:
x = −0.8
Step-by-step explanation:
−2.7 + x = −3.5
1.) Simplify both sides of the equation
x − 2.7 = −3.5
2.) Add 2.7 to both sides
x − 2.7 + 2.7 = −3.5 + 2.7
AND BAYUM...
x = −0.8
