Answer:
100=25.99b+15.99dStep-by-step explanation:
step one:
let the number of Blu-rays be b and
DVDS be d,
step two:
given that Blu-rays cost $25.99each and
DVDS cost $15.99 each,
we can model the cost of the Blu-rays and DVDS, as
100=25.99b+15.99d
hence the expression for the number of Blu-rays and DVDS, is given as
100=25.99b+15.99d

Hello again! I need help with this question!
Answer:
(f o g) = -5x+22
Step-by-step explanation:
f o g basically means f(g(x))
So:
f(g(x)) = -5(x-4)+2
f(g(x)) = -5x+20+2
f(g(x)) = -5x+22
Therefore: (f o g) = -5x+22
This is called function composition. Basically, the output of g(x) goes into the input of f(x).

The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Josh is comparing the cost of having his car wash plus filling up his tank with gas at each business. How many gallons of gas would he need to purchase for the cost to be the same at each car wash?
Answer:
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash
Step-by-step explanation:
We need to model both car wash's costs. The Quik-Clean Car Wash charges $15 for a car wash plus $2.50 per gallon for unleaded gasoline. If x is the number of gallons of unleaded gasoline. the total charges of this store are:
C1=15+2.5*x
The Mighty Clean Car Wash charges $10 for a carwash plus $2.75 per gallon for unleaded gasoline. Following the same procedure, their costs are:
C2=10+2.75*x
Josh wants to know how many gallons of gas will make both businesses charge the same. Equating both equations:
15+2.5*x=10+2.75*x
Simplifying:
-0.25x=-5
Solving:
x=-5/(-0.25)=20
Josh would need to purchase 20 gallons of gas for the cost to be the same at each car wash

Find the value of this triangle!
Answer:
x=35
y=145
z=25
Step-by-step explanation:
(do first)x:
55 + 90 = 145
180-145=35
(do last)y:
25+10=35
180-35=145
(do second)z:
65+90=155
180-155=25
Answer:
x = 35, y = 145, z = 25
Step-by-step explanation:
All triangles' angles have a sum of 180°. Because we know this, we can solve the first triangle easily.
180 = x + 90 + 55
180 = x + 145
35 = x
Angles x and y are what we call suplementary angles. This means they have a sum of 180°.
180 = 35 + y
145 = y
Once again, we know that triangles have a sum of 180°. So the next triangle should now be easy to solve.
180 = 10 + 145 + z
180 = 155 + z
25 = z

Find the zeros of the function f(x) = -5x2 + 4x - 1 by completing the square.
(leave in fraction form if necessary)
Answer:
The roots are;
x = (2 + i)/5 or (2-i)/5
where the term i is the complex number representing the square root of -1
Step-by-step explanation:
Here, we want to use the completing the square method to solve the quadratic equation;
f(x) = -5x^2 + 4x -1
Set the function to zero
0 = -5x^2 + 4x - 1
So;
-5x^2 + 4x = 1
divide through by the coefficient of x which is -5
x^2 - 4/5x = -1/5
We now take half of the coefficient of x and square it
= -2/5^2 = 4/25
add it to both sides
x^2 - 4x/5 + 4/25= -1/5 + 4/25
(x- 2/5)^2 = -1/5 + 4/25
(x - 2/5)^2 = -1/25
Take the square root of both sides
x - 2/5 = √( -1/25
x - 2/5 = +i/5 or -i/5
x = 2/5 + i/5 or 2/5 - i/5

Select the correct answer from each drop-down menu. Samson is making a shipping box out of a 2-foot by 4-foot piece of cardboard. He will cut two squares of side length x and two rectangles with a width of x out of the cardboard and then fold the cardboard along the lines to make the box. He models the volume, , in cubic feet, as a function of the length x, in feet. He created the diagram and graph to model the box and its volume. Image not drawn to scale The zeros of function v occur at 0 and 1 . To make the box, Samson should use a value for x.
Answer: 0 and 1, less than 0

It takes a boat 3 hours to travel 45 miles downstream and 4 hours to travel 44 miles upstream.
What is the speed of the boat in still water?
The boat travels at...
miles per hour in still water.
What is the speed of the current of the river?
The speed of the current is...
miles per hour.
Answer:
2 miles per hour
Step-by-step explanation:
We use the distance formula. D = r * t
45/3 = 15 mph | Trip 1 |
44/4= 11mph | Trip 2 |
15-11 = 4 mph difference traveling upstream or downstream. Thus the speed of the current is 2 miles per hour.

Find the measure of this angle, and explain your answer.
Answer:
50
Step-by-step explanation:
180 - 90+40 = 50
Answer:
Answer: 50 degrees
Step-by-step explanation:
important things to know:the square in the bottom right means 90°all angles in a triangle add up to 180°using this knowledge, you can make the following equation:
90 + 40 + x = 180
130 + x = 180
now subtract 130 from both sides.
x = 180 - 130
x = 50°

A pipe cleaner lay across a wire shelf. The wires that make up the shelf are parallel, and the pipe cleaner is a transversal. The parallel wires are labeled a, b, and, c, and the angles are labeled with numbers. Parallel lines a, b, and c are cut by a pipe cleaner transversal. All angles are described clockwise, from uppercase left. Where line a intersects with the pipe cleaner, the angles are: 1, 2, 4, 3. Where line b intersects with the pipe cleaner, the angles are 5, 6, 8, 7. Where line c intersects with the pipe cleaner, the angles are: 9, 130 degrees, 12, 11. The measure of one angle is 130°. Which statement is true regarding the 130° angle and angle 3? They are same-side interior angles, so angle 3 measures 50°. They are alternate interior angles, so angle 3 also measures 130°. They are corresponding angles, so angle 3 also measures 130°. They are alternate exterior angles, so angle 3 measures 50°.
Answer:
B. They are alternate interior angles, so angle 3 also measures 130°.
Explanation: This is the correct answer on Edge 2021, just took the unit test. Hope this helps ^-^.
They are alternate interior angles, so angle 3 also measures 130°. The correct option is B.
What are alternate interior angles?The angle formed by the line intersecting two parallel lines is called the alternate interior angle. These two angles are equal in magnitude.
Here, according to the given figure, lines a and c are parallel lines and pipe cleaner is a transversal that is passing through these parallel lines.
Therefore, by the property of parallel lines, the corresponding and alternative exterior or interior angles made by the common transversal ( pipe cleaner) on lines a and c must be equal, and here ∠3 and 130° are alternative interior angles by lines a and c with the same transversal, So, they must be equal.
The complete question is given below:-

Tammy purchased a prepaid phone card for $15. Long distance calls cost 18 cents a minute using this card. Tammy used her card only once to make a long
distance call. If the remaining credit on her card is $6.72, how many minutes did her call last?
Answer:
46 minutes
Step-by-step explanation:
Sorry about not answering your question sooner, but here is your answer:
In order to get the answer, we have to subtract the original amount of money on the phone card by the amount left ver after the call:
15 - 6.72 = 8.28
Then, we divide this number by 0.18:
8.28 / 0.18 = 46
So, Tammy's call lasted 46 minutes
Hope this helps :)
