Which of the sets of ordered pairs represents a function?
A = {(3, −5), (4, 6), (3, 9), (2, 7)}
B = {(2, 4), (−1, 4), (5, 4), (4, 4)}
a
Both A and B
b
Only B
c
Only A
d
Neither A nor B
Answer:
B
Step-by-step explanation:
A does not represent a function because the x-value of 3 appears twice, and by the defenition of a function, the x-value cannot appear twice for it to be considered a function. B could be a function because the x-values are not repeated.
Therefore the answer is B, only B is a function.
There are 32 vanilla cupcakes and 40 chocolate cupcakes at a bakery. All of the cupcakes must be placed in boxes with the same number of vanilla cupcakes and the same number of chocolate cupcakes in each box.
Answer:
5 to 4
Step-by-step explanation:
when it's asking for a ratio it's basically division
chocolate/vanilla = 40/32 = 5/4
5/4 is the same as 5:4 or 5 to 4
can anybody help me with this?
Answer:
a) 3.6 × 10²
Time = distance / speed
So time = 1.08 × 10⁸ / 3 × 10⁸
= 1.08 × 10¹¹ / 3 × 10⁸ ( converted 10⁸ km to meter )
= 1.08 × 10³ / 3
= 0.36 × 10³
. = 3.6 × 10²
Time = 3.6 × 10²
Find the width of the rectangle if the length of the rectangle is 5 more than it’s width, and the perimeter of the rectangle is 20 units
Answer:
w = 2.5
Step-by-step explanation:
Write these 2 equations to represent the problem:
[tex]l=w+5\\2w+2l=20[/tex]
where w is width and l is length. This can then be solved as a system of equatios. I'll solve by substitution, and as the [tex]l[/tex] is already solved for at the top:
[tex]2w+2l=20\\2w+2(w+5)=20\\2w+2w+10=20\\4w+10=20\\4w=10\\w=2.5[/tex]
If you just need the width, then you're already done there. I'll find the other variable too, and then check it to be sure it's correct.
[tex]l=w+5\\l=(2.5)+5\\l=7.5[/tex]
Now, confirm that with the second equation:
[tex]2w+2l=20\\2(2.5)+2(7.5)=20\\5+15=20\\20=20[/tex]
The perimeter of a rectangle is the sum of its side lengths.
The width of the rectangle is 2.5 units
Represent the length with l and the width with w.
So, we have:
[tex]P =2 \times (l + w)[/tex] --- the formula of perimeter
The perimeter is 20 units.
So, we have:
[tex]20 =2 \times (l + w)[/tex]
Divide both sides of the equation by 2
[tex]10 =l + w[/tex]
The length is said to be 5 more than its width.
So, we have:
[tex]l =5 + w[/tex]
Substitute 5 + w for l in [tex]10 =l + w[/tex]
[tex]10 = 5 + w + w[/tex]
[tex]10 = 5 + 2w[/tex]
Subtract 5 from both sides
[tex]5 = 2w[/tex]
Divide both sides by 2
[tex]2.5 = w[/tex]
Rewrite as:
[tex]w =2.5[/tex]
Hence, the width of the rectangle is 2.5 units

I need the answers and explanation to a b c and d
Answer:
a) 4x -3y ≥ -24
b) 2x +3y ≥ -12
c) 4x -3y ≤ 12
d) 2x +3y ≤ 24
Step-by-step explanation:
All of the given points are on the axes, so it is useful to know the intercept form of the equation for a line is ...
x/a +y/b = 1 . . . . . . where a is the x-intercept and b is the y-intercept.
a)The boundary line for the first side is ...
x/-6 +y/8 = 1
4x -3y = -24 . . . . . . multiply by -24 to put in standard form
The graph shows the quadrilateral is to the right of this line, so its inequality is ...
4x -3y ≥ -24
__
b)The boundary line for side 2 has equation ...
x/-6 +y/-4 = 1
2x +3y = -12 . . . . . multiply by -12
The quadrilateral is to the right of this line, as well, so its inequality is ...
2x +3y ≥ -12
__
c)We can see from the graph that the x-intercept of the boundary line for side 3 is x=3. The equation for that boundary line is ...
x/3 +y/-4 = 1
4x -3y = 12
The quadrilateral is to the left of this line, so its inequality is ...
4x -3y ≤ 12
__
d)Apparently, side 4 is intended to use points already given. We assume it passes through (6, 4) and (0, 8). This boundary is parallel to side 2, so will have the same equation, but with a different constant.
2x +3y = 2(0) +3(8) = 24
The quadrilateral is to the left of this line, so its inequality is ...
2x +3y ≤ 24
__
The second attachment shows a graph of the four inequalities with their shading.
_____
Additional comment
All of the inequalities are written in standard form, so the x-coefficient is positive for all of them. The direction of the inequality symbol can be chosen to select values of x that are greater than or less than those on the boundary line. If the shading is to be to the right, then larger x-values are required, and the inequality will have the form ax + by ≥ c (a > 0). If shading is to the left, then smaller x-values are required, and the inequality symbol points in the other direction.

Prove the following theorem:
Given 3 different lines a, b, and c. If a is parallel to b (a║b), and c intersects a (c∩a), then prove that c intersects b (c∩b).
Answer:
Well, I think this is correct:
Well, if we know that a and b are parallel, that means they have the same slope but different y-intercept. So, if c and a intersects, then c and b are bound to intercept, because when c intersects with a, it will also cross b, since it will be going in the same route...which will make it also intersect with b. (crossing.)
Sorry if I'm wrong.
Hope this helps! :)

Calculate the value of 4321 (base 5) + 343 (base 5)
In the "1s" place,
1₅ + 3₅ = 4₅
In the "5s" place,
2₅ + 4₅ = (6)₅ = (5 + 1)₅ = 10₅ + 1₅ = 11₅
In the "25s" place, we carry the leading 1 from the "5s" place,
3₅ + 3₅ + 1₅ = (7)₅ = (5 + 2)₅ = 10₅ + 2₅ = 12₅
In the "125s" place, we carry over the 1 again,
4₅ + 1₅ = (5)₅ = (5 + 0)₅ = 10₅ + 0₅ = 10₅
Putting everything together,
4321₅ + 343₅ = 10214₅

A youth group earns $600 for charity and decides to put it in a bank. Calculate the amount of money the group will have for each scenario.
Part A chase bank pays simple interest at 5% and the group leaves the money for 5 years
part B witney bank pays an interest rate of 4% compounded annually and the group leaves the money for 6 years
Based on the types of compounding and the interest rates, the following are true:
Part A - The group will have $750Part B - The group will have $759.19When using simple interest, the amount the group will have is:
= Amount x ( 1 + rate x number of years )
= 600 x ( 1 + 5% x 5)
= $750
When using compound interest, the group will have:
= Amount x ( 1 + rate) ^ Number of years
= 600 x ( 1 + 4%)⁶
= $759.19
In conclusion, compound interest yields more.
