Answer:
x2-20x+100
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
The required trinomial in standard form is x²+20x+100.
Trinomial:Important information:
The expression is the [tex](x+10)^2[/tex].Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+10)^2=(x)^2+2(x)(10)+(10)^2[/tex]
[tex](x+10)^2=x^2+20x+100[/tex]
Therefore, the required trinomial in standard form is x²+20x+100.

a student cost for last semester at her community college was $2200. she spent $308 of that on books. what % of last semesters college costs was spent on books
Answer:
We conclude that 14% of last semester's college cost was spent on books.
Step-by-step explanation:
The cost spent at community college = $2200
The amount spent on books = $308
The % of last semesters college costs was spent on books can be determined using the formula
% spent books on = [308 / 2200] × 100
= 0.14 × 100
= 14%
Therefore, we conclude that 14% of last semester's college cost was spent on books.
A company makes 140 bags.
21 of the bags have buttons but no zips.
25 of the bags have zips but no buttons.
45 of the bags have neither zips nor buttons.
How many bags have zips on them?
A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object. The total number of bags that have both zips and buttons is 49.
What is a set?A set is a mathematical model for a collection of items; it comprises elements or members, which may be any mathematical object: numbers, symbols, points in space, lines, other geometrical structures, variables, or even other sets.
Given that A company makes 140 bags. 21 of the bags have buttons but no zips. 25 of the bags have zips but no buttons. 45 of the bags have neither zips nor buttons.
Now, we can write the following things about the given condition,
Total number of bags, s = 140
Bags with Only zips, only Z = 25
Bags with only buttons, only B = 21
Bags with neither or them, Z'∩B' = 45
Now, the total number of bags that have both of them is,
Z∩B = s - only Z - only B - Z'∩B'
= 140 - 25 - 21 - 45
= 49
Hence, the total number of bags that have both zips and buttons is 49.

Given
[tex]Drone = d[/tex]
Friend = $35 more expensive than yours.
Brother = 3 * as much as your friend
Required
Write an expression for the cost of your brother's drone
I'll solve by analysing the question one sentence after the other
You:
[tex]Drone = d[/tex]
Your friend:
Friend = $35 more expensive than yours.
This means
[tex]Friend = 35 + You[/tex]
Substitute d for You
[tex]Friend = 35 + d[/tex]
Your brother:
Brother = 3 * as much as your friend
This means:
[tex]Brother = 3 * Friend[/tex]
Substitute 35 + d for Friend
[tex]Brother = 3 * (35 + d)[/tex]
Open bracket
[tex]Brother = 3 * 35 + 3*d[/tex]
[tex]Brother = 105 + 3d[/tex]

Tara is graphing the equation 4x + 2y = 10. Which of these shows the correct equation in slope-intercept form, slope, and y-intercept?
Question 2 options:
y = –2x + 5
slope = –2
y-intercept = 5
y = 2x + 4
slope = 2
y-intercept = 4
y = –4x + 5
slope = –4
y-intercept = 5
y = 4x + 5
slope = 4
y-intercept = 5
Answer: y = -2x + 5
Step-by-step explanation:
y = -2x + 5
slope = -2
Slope intercept form of equation of line is given by y = mx + c
where m is the slope of line
c is the y intercept i.e point where given line intersect y axis.
________________________________________________
given equation 4x + 2y = 10
we have to re-write this equation in form y = mx + c
4x + 2y = 10
subtraction 4x from LHS and RHS
4x + 2y - 4x= 10 - 4x
2y = 10- 4x
we have to eliminate 2 from y for that we
divide LHS and RHS by 2 we
2y /2 = 10/2- 4x/2
y = 5 - 2x
rearranging it in y = mx+c form
y = -2x + 5
thus, m = -2 , c = 5
Answer:
y=-2x+5, slope= -2, y-intercept= 5 (so, first option)
Step-by-step explanation:
y=mx+b. m is the slope, and b is the y-intercept. to get the equation to the slope intercept form, you get y by itself- subtract 4x from both sides and then divide by 2 on both sides.
How am I supposed to do this?
For literal equations you do not necessarily need a numerical answer. You just need to get the variable you are supposed to solve for on one side of the equation by itself. To do this you will follow the same steps you do when you normally solve for x (or any other variable)
#9-Step by step
Q=25[tex]\pi[/tex]h
divide 25[tex]\pi[/tex] on both sides of the equation
Q/25[tex]\pi[/tex]=h
h=Q/25[tex]\pi[/tex]
Since his can't be simplified any further this is your answer
#11. y=7m+6
First subtract 6 over to the other side
y-6=7m
then divide the 7 over
(y-6)/7=m
m=(y-6)/7
#13 A=(Z+7)3
Divide the three over to the other side of the equation
A/3=Z+7
Now the 7 is free to be subtracted from both sides
(A/3)-7=Z
#17. (2x/5)-9=6
First add 9 to both sides
2x/5=6+9
2x/5=15
Multiply both sides of the equation by 5
2x=5(15)
2x=75
Divide by 2
x=75/2
x=37.5

Answer:
x=2
Step-by-step explanation:
First you put the equations in the form of y = mx + b
Then once they are like that it would look like:
y = -2x + 6
y = 3x - 4
So then you can set them equal to each other and it will look like this:
-2x + 6 = 3x - 4
Then you add 2x to both sides and get:
6 = 5x - 4
Next, add 4 to both sides and get:
10 = 5x
So then you will simplify by dividing both sides by 5 and getting:
2 = x

Find the value of p and q such that
2x^2 - 4x + 3= 2 (x-p)^2 + q
PLEASE ANSWER!!!
Answer:
The values of p and q such that 2·x² - 4·x + 3 = 2·(x - p)² + q, are;
p = 1, q = 1
Step-by-step explanation:
The given equation are;
2·x² - 4·x + 3 = 2·(x - p)² + q
By expanding the right hand side of the equation, we have;
2·x² - 4·x + 3 = 2·(x - p)² + q = 2·x² - 4·p·x + 2·p² + q
2·x² - 4·x + 3 = 2·x² - 4·p·x + 2·p² + q
Comparing the coefficient of x in both equations, gives;
2·x² + (- 4)·x + 3 = 2·x² + (- 4·p)·x + 2·p² + q
-4 = -4·p
∴ p = -4/(-4) = 1
p = 1
Comparing only the constant terms (terms not multiplied by "x" or "x²"), we get;
3 = 2·p² + q
Substituting the value for "p" obtained above (p = 1 ) in the previous equation, we get;
3 = 2 × 1² + q = 2 + q
∴ q = 3 - 2 = 1
q = 1.
