Answer:
Acording to my brain the answer is (-2,-1) In other Words The correct answer is Option B
Step-by-step explanation:
God Bless :)
The ordered pair that needs to be removed in order for the mapping to represent a function is either: (-2, -1) or (2, -2).
What is a function?The term "function" refers to a relationship between a set of inputs and outputs. Just one output is connected to each input in a function, which connects inputs in that manner. Every function has a domain, co-domain, and range.
To represent a function, each input (x-value) must be associated with only one output (y-value). Therefore, in order for the mapping to represent a function, we need to remove any ordered pairs that violate this rule.
Looking at the options given, we can see that only one option has a repeated x-value:
O (-2, -1) and 0 (2, -2)
Both of these ordered pairs have the same x-value (either -2 or 2), but different y-values. This means that they violate the rule that each input must be associated with only one output.
Therefore, the ordered pair that needs to be removed in order for the mapping to represent a function is either:
O (-2, -1)
or
0 (2, -2)
We need to remove one of these ordered pairs to make the mapping a function.

Answer:
6 1/10
Step-by-step explanation:
You multiply the left fraction by 5 and the right by 2 so the denominators come out equally as 10 which makes your new fractions, 4 5/10 and 1 6/10 then add them together and it would be 5 11/10 and you break it down so it’s 6 with 1 left over making it 6 1/10
Match the reasons with the statements.
GIVEN: x2 + 6x + 2x + 12 = 0
TO PROVE: x = -6 or x = -2
1. x2 + 6x + 2x + 12 = 0 Combining like terms
2. x2 + 8x + 12 = 0 Distributive Postulate
3. (x + 6)(x + 2) = 0 Zero product postulate
4. x + 6 = 0 or x + 2 = 0 Subtraction property of equality
5. x = -6 or x = -2 Given
I WILL REPORT U IF U DONT ANSWER CORRECTLY AND FULLY!!!!
Answer:
Concept: Mathematical Derivation
We are given x^2 +6x+2x+12 Hence we simplify: x^2 + 8x +12 Now we factor: (x+2)(x+6) By mathematical logic we now proved that the roots are x=-2 and x=-6 Give brainlist and rate positivelyPART OF A STUDY SET!!!! NEED THE ANSWER ASAP BEING TIMED GIVING BRINLY AND THANKS FOR HELP!!!!!!!!

Solve each equation mentally for x.
5/2 • x = 1
Your answer must be in the form of a fraction.
You need to get x by itself to solve
So to get rid of 5/2, you need to multiply both sides by the reciprocal or 2/5...
5/2*2/5 = 1 which we don't write and 1*2/5 = 2/5
So now you'd have x =2/5
Which values of x and y satisfy the system
of equations below?
3x + 5y = 22
- 4x - 5y = -26
A. x = -4, y = 2
C. x= 2, y = 4
D. x= 4, y = 2
B. x= -2, y - 4.
Answer:
D. x= 4, y = 2
Step-by-step explanation:
Since it's multiple choice, you can plug in the values
9. Find the point of intersection of the lines: y = 4x + 1 and y = - 2x + 4 A. (2,9) B.(1/2,3) C. (1,2) D. (1/4,2)
Step-by-step explanation:
y = 4x + 1 and y = -2x + 4
4x + 1 = -2x + 4, 6x = 3, x = 0.5
When x = 0.5, y = 4(0.5) + 1 = 3.
The point of intersection is (0.5, 3). (B)
Step-by-step explanation:
y = 4x + 1
A.(2,9)
y = 4(2) + 1 = 9
y = 9.
y = 4x + 1
9 = 4x + 1
9 - 1 = 4x
8 = 4x => x = 8÷4 = 2
x = 2.
y = -2x + 4.
A.(2,9)
y = -2(2) + 4 = 0
y = 0.
y = - 2x + 4
0 = -2x + 4
0 - 4 = 2x
0 = 2x => x = 0 ÷ 2 = 0
x = 0.
y = 4x + 1
B.(1/2, 3)
y = 4(1/2) + 1
y = 4 ÷ 2 + 1 = 3
y = 3.
y = 4x + 1
3 = 4x + 1
3 - 1 = 4x
2 = 4x => x = 2 ÷ 4 = 1/2
x = 1/2.
y = - 2x + 4
B.(1/2, 3)
3 = - 2x + 4
3 - 4 = - 2x
- 1 = - 2x => x = 1/2
x = 1/2.
y = - 2x + 4
y = - 2(1/2) + 4
y = -2(0.5)+ 4
y = -1 + 4 = 3
y = 4x + 1
C.(1,2)
y = 4(1) + 1 = 5
y = 5.
y = 4x + 1
5 = 4x + 1
5 - 1 = 4x
4 = 4x => x = 4÷4 =1
x = 1.
y = -2x + 4
C.(1, 2)
y = - 2(1) + 4
y = - 2 + 4 = 2
y = 2.
2 = -2x + 4
2 - 4 = - 2x
- 2 = - 2x => x = 2÷2 = 1
x = 1.
y = 4x + 1
D.(1/4, 2)
y = 4(1/4) + 1
y = 4(0.25) + 1
y = 1 + 1 = 2
y = 2.
y = 4x + 1
2 = 4x + 1
2 - 1 = 4x
1 = 4x => x = 1/4
Point A is the point of intersection of the lines.

Use the elimination Method to solve the system of equations. Choose the correct ordered pair.
6x + 4y = 32
-6x+4y = 8
A: 4,2
B: 1,5
C: 0,8
D: 2,5
Answer:
D, 2; 5
Step-by-step explanation:
Sum the equations vertically to eliminate at least one variable.
You will obtain 8y = 40.
Divide both sides by 8. You will get y = 5.
Now we know the value or y. Substitute this value into the second equation (-6x+4y = 8). You will get -6x+(4×5) = 8. Multiply 4 and 5: -6x+20 = 8.
Solve for x by moving 20 to the other side and switching sign: -6x = 8-20.
So: -6x = -12 and therefore x = 2.
So now we know the value of x and y.
(x; y) = (2; 5)
The manager of a clothing store purchased 40 pairs of jeans for $500. She plans to sell each pair of jeans for $19.99. By what percent did she mark up the price?
A.
60%
B.
12.5%
C.
10%
D.
7.5%
Answer:
60%
Step-by-step explanation:
Formula: Markup Percentage = Selling Price Per Unit - Cost Price Per Unit over Cost price per unit. times 100
$19.99 - 12.5
------------------- times 100
12.5
Follow PEMDAS
7.49 / 12.5 = 0.5592 (100) = 59.92
Round to the nearest whole number. So about 60%

Step-by-step explanation:
Tara has ridden her bike .5 miles and
rides 10 miles per hour. Felipe has
ridden his bike .25 miles and rides 15
miles per hour. For what number of
hours will-Tara have ridden less miles
than Felipe?
Answer:
0.5 hours
Step-by-step explanation:
Given that Tara has covered 0.50 miles and rides with a speed of 10 miles/hour. Felipe has covered bike 0.25 miles and rides with a speed of 15 miles/hour.
Tara has covered more distance while the speed of Felipe is more than the speed of Tara.
Assuming that in time t hour, Felipe reaches Tara, then Tara left behind as Felipe has faster speed.
So, after t hour, Felipe will be ahead of Tara and Tara will cover lesser miles than Felipe .
As distance = speed x time, so
So, the distance covered by Tara in [tex]t[/tex] hour = 10t miles and she already has covered 0.5 miles, so total distance covered by Tara [tex]= 0.5+10t[/tex] miles.
Similarly, the distance covered by Felipe in [tex]t[/tex] hour = 15t miles and he already has covered 0.25 miles, so the total distance covered by Tara [tex]= 0.25+15t[/tex] miles.
Therefore, at the time then Felipe reached Tara, both have covered the same distance, i.e
[tex]0.25+15t=0.5+10t \\\\\Rightarrow 15t-10t=0.5-0.25 \\\\\Rightarrow 5t=0.25 \\\\[/tex]
[tex]\Rightarrow t= 0.25/5=0.5[/tex] hour
Hence, after 0.5 hours Tara will cover lesser miles than Felipe .
Answer:
0.5 hours

Mariana is choosing a beverage to drink. She wants a beverage with no more than 3 grams of sugar per ounce. Which beverages meet Mariana's requirements?
Answer:
Step-by-step explanation:
The main beverage that would easily meet Mariana's requirements would be water as it contains no sugar. Other than these two flavored options that she can choose from would be to make home-made Ice-tea or lemonade. Therefore, she can choose the amount of sugar to add without going over her own requirements, but still having a delicious beverage to drink.
