f(x)=x2-4
f(-1) =
f(0)=
f(5)=
Answer:
-6, -4, 6
Step-by-step explanation:
1.) f(-1)= (-1)2 - 4
= -2-4
= -6
2.) f(0)=(0)2-4
= -4
3.) f(5)= (5)2 -4
=10-4

Keiko purchased a prepaid phone card for $20 . Long distance calls cost 16 cents a minute using this card. Keiko used her card only once to make a long distance call. If the remaining credit on her card is $17.28 , how many minutes did her call last?
Answer:
17 minutes
Step-by-step explanation:
To answer this question, all we have to do is subtract the original amount of money on the phone card by what is remaining after Keiko's call:
20 - 17.28 = 2.72
Now, we divide this number by 0.16:
2.72 / 0.16 = 17
So, Keiko's call lasted 17 minutes
Hope this helps :)
convert 3x- y=7 to slope intercept form
Answer:
y = 3x - 7
Step-by-step explanation:
-y = -3x + 7
divide both sides by -1 to get rid of the negatives
y = 3x - 7

Nolan gave out a survey to some students in his school about their favorite color. Students could choose between red and purple. 238 of those surveyed said their favorite color was red. 66% of the students surveyed said their favorite color was purple. How many students were surveyed in total?
Answer:
700
Step-by-step explanation:
100%-66%=34%
34% equals the 238 that is red
238÷34%=7 people per percentage
7×66%= 462 students that chose purple
462+238=700 which should be the total amount of people surveyed.
Find the solution to the syster
y = 2x = 5
y = X - 2
Answer:
Both of these equations are in slope-intercept form. The slope-intercept form of a linear equation is: y=mx+b
Where m is the y-intercept value.
y=-2x+5
y=-2x+20
The slope of the two equations are: m1=−2 and m2=−2
Step-by-step explanation:
Because the have the same slope it means the lines represented by these two equations are either parallel or are the same line.
The y-intercepts for the two lines are:b1 = 5 and b1=20

How many unit cubes are required to create a larger cube with edge length of 3 units? Can I also get an explanation so I know how it's done? Thanks :)
Answer:
The unit cubes that are required to create a larger cube with an edge length of 3 units is:
27 cubes.Step-by-step explanation:
To identify the number of cubes you need to create a larger cube, you must think in the number of cubes of the length (3 cubes in this case), and use the exponent 3, because you need to form a cube. Below I'll show you:
[tex]3^{3}= 27 cubes.[/tex]To understand it in a better form, suppose that you need a cube with an edge of 5 units, in that case, remember you use the number 5 how base and the exponent is 3, because is a cube, in that case, it would be:
[tex]5^{3}= 125 cubes[/tex]If it wasn't a cube but a square, you must elevate to the number 2, in the case of the cube is elevated to 3, so, the unit cubes that are required to create a larger cube with an edge length of 3 units is 27 cubes.
[tex] \sqrt{147} - \sqrt{75} + \sqrt{27} [/tex]
The vertex of this parabola is at (-1,-3). Which of the following could be its equation?
61,-3)
A. x=-2(y + 1)2-3
B. x=-2(y-1)2-3
C. x= -2(y + 3)2-1
D. x = -2(y-3)2-1
Answer:
NONEThe vertex form of an equation of the parabola with vertex (-1,-3) is:
y = a(x + 1)² - 3where a could be any number, also -2,
Step-by-step explanation:
The vertex form of an equation of the parabola:
y = a(x - h)² + k
vertex is (-1, -3) so h = -1, k = -3
so:
y = a(x - (-1))² + (-3)
y = a(x + 1)² - 3
compare and contrast between x-intercept and y-intercept
Answer:
"The x-intercept is the point at which the graph crosses the x-axis... ...The y-intercept is the point at which the graph crosses the y-axis." (Lumen)
The x-intercept is on the horizontal axis while the y-intercept is vertical axis. Aside from that they are practically the same and serve the same purpose while graphing, they just go in differing positions.

Carrie needs to determine the number of towels that will fit each row along the back of the shower if the back of the shower measures 6 feet long and each towel is 2/3 a foot long which equation shows how to determine the number of tiles that will fit in each row
Answer:
6 / 2/3 = 9
Step-by-step explanation:
Carrie want to find out the number of towels that will fit each row along the back of the shower
The back of the shower measures 6 ft long
Each towel is 2/3 foot long
Therefore the equation which shows how to determine the number of tile that will fit in each row is
Since 1 tile is 2/3 foot long then the number the number of tile in each row is
= 6 / 2/3
= 6 ×3/2
= 18/2
= 9
Credit card A is running a promotion where they will charge 0% interest for the first year, and then 0.8% compounded continuously after that. Credit card B has an interest rate of 0.7%, also compounded continuously. If you are going to make a $500 purchase and plan to not make a single payment for 2.5 years, which credit card should you go with? Write the equation showing the total balance at the end of 2.5 years for that card. How much money invested at 5% compounded continuously for 3 years will yield $820

The mass of Earth is about 6 x 10^24 kilograms. The mass of the moon is about
7 x 10^ 22 kilograms. The mass of Jupiter is about 2 times 10^27 kilograms.
About how many times as large is Earth's mass compared to the moon's mass? Justify your answer.
About how many times as large is Jupiter's mass compared to Earth's mass? Justify your answer.
Answer:
Earth is 85.71 times heavier than moonJupiter is 333.33 times heavier than EarthStep-by-step explanation:
Given
The mass of Earth is about 6 x 10^24 kilograms = eThe mass of the moon is about 7 x 10^ 22 kilograms = mThe mass of Jupiter is about 2 x 10^27 kilograms = jThe difference in mass
e/m = 6 x 10^24 / 7 x 10^ 22 = 600/7 = 85.71Earth is 85.71 times heavier than moon
j/e = 2 x 10^27 / 6 x 10^24 = 2000/6 = 333.33Jupiter is 333.33 times heavier than Earth
In Aunt Peggy’s backyard there are cows and chickens. There are 20 more chickens than cows. The total number of legs is 130. How many chickens and how many cows are there? (Each cow has 4 legs, each chicken has 2 legs.) PLZ HELP! Will mark brainliest
Answer:
There are 15 cows and 35 chickens
Step-by-step explanation:
So first you take 20 and multiply it by two since there are two legs on each chicken. You get 40.
Then you subtract 40 from 130. You get 90.
Since the cow has double the legs of the chicken, you can count the cow as two chicken.
You divide 90 by 3. You get 30.
To get the number of chicken you divide 30 by 2 and you get 15.
You add 15 and 20 together and you get 35 chickens.
To get the number of cows you divide 30 by 2 and you get 15.
So you have your answer. 35 chicken and 15 cows.
