Answer:
[tex]y = -100x + 13000[/tex]
Step-by-step explanation:
See attachment for graph
First, we need to take any corresponding values of x and y
[tex](x_1,y_1) = (0,13000)[/tex]
[tex](x_2,y_2) = (130,0)[/tex]
Next, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{0 - 13000}{130 - 0}[/tex]
[tex]m = \frac{- 13000}{130}[/tex]
[tex]m = -100[/tex]
Next, we calculate the line equation using:
[tex]y - y_1=m(x-x_1)[/tex]
[tex]y - 13000 = -100(x - 0)[/tex]
[tex]y - 13000 = -100x[/tex]
Make y the subject
[tex]y = -100x + 13000[/tex]
Hence, the line equation is:
[tex]y = -100x + 13000[/tex]
Ben needs to buy an equal number of sunglasses and beach balls to place in gift bags. Each pair of sunglasses costs $4 and each beach ball costs $2.50. If he has $45 to spend on the sunglasses and beach balls, then the inequality 4x + 2.5x greater than or equal to 45 can be used to find the number of each item he can buy. How much money will he have left after buying the greatest number of sunglasses and beach balls?
$0.09 will he have left after buying the greatest number of sunglasses and beach balls.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Model Inequality: 4x + 2.5x ≥ 45.
Now, solving for inequality
4x + 2.5x ≥ 45.
(4 + 2.5)x ≥ 45
6.5x ≥ 45
x ≥ 45/ 6.5
x≥ 6.92
x≥ 7 (approx)
So, the max price for sunglasses and beach balls = 4(6.92)+ 2.5(6.92)
= $44.91
Thus, the left money is = 45- 44.91 = $ 0.09

Which of the following sets are disjoint?
a) Men and uncles
b) Aunts and uncles
c) Women and Aunts
d) They are all disjoint
=======================================================
Explanation:
The term "disjoint" is another way of saying "mutually exclusive". If two sets are disjoint, then they have nothing in common. Put another way, if two sets are disjoint, then it's not possible to be part of both sets at the same time.
In this case, it is not possible to be both an aunt and an uncle simultaneously for any one person. So this is why choice B is the answer.

which of the following is an irrational number?
Answer:
B
Step-by-step explanation:
The other choices are terminal numbers which makes them rational numbers but square root of 19 is an irrational number because square root of 19 is 4.3588989.... This makes it an irrational number since it's just random numbers after the decimal point.

Answer: x =5
Step-by-step explanation:
[tex]x + 3 + 3(x + 2) = - 24[/tex]
[tex]x + 3 + 3x + 6 = - 24[/tex]
[tex]4x + 9 = - 24[/tex]

The discrimination of a quadratic function is 13. Which is a true statement about the roots of the function?
Answer:
If the discrimination of a quadratic function is 13, then the function will have two distinct real roots.
Step-by-step explanation:
Given the quadratic function
[tex]y=ax^2+bx+c[/tex]
where D = b²-4ac is called the discrimination of a quadratic function.
The discriminant D=b²-4ac indicates the type of roots the equation may have.
If D > 0, then the equation has two distinct real roots.
Given that the discrimination of a quadratic function is 13.
i.e. D = 13
As D > 0, so the function will have two distinct real roots.Thus, we conclude that if the discrimination of a quadratic function is 13, then the function will have two distinct real roots.

Answer:
VP = 21
ZP = 7
Step-by-step explanation:
Given:
VZ = 14
Required:
VP and ZP
Solution:
Since Z is the centroid, therefore:
⅔ of VP = VZ (centroid theorem)
Thus,
⅔(VP) = 14 (substitution)
Multiply both sides by 3
2(VP) = 14*3
2(VP) = 42
Divide both sides by 2
VP = 42/2
VP = 21
✅VZ + ZP = VP
14 + ZP = 21
ZP = 21 - 14 (subtraction property of equality)
ZP = 7

Nadine saw that there was 4/5 of a pie left after their family picnic. Each slice of pie was 1/15 of the total pie. How many slices of pie are left?
Given:
4/5 of a pie left after their family picnic.
Each slice of pie was 1/15 of the total pie.
To find:
The number of remaining slices of pie.
Solution:
Let x be the number of remaining slices of pie.
Part of total pie in one slice = [tex]\dfrac{1}{15}[/tex]
Remaining part of total pie in x slices = [tex]\dfrac{1}{15}x[/tex]
According to the question, 4/5 of a pie left after their family picnic.
[tex]\dfrac{1}{15}x=\dfrac{4}{5}[/tex]
Using cross multiplication, we get
[tex]5\times x=15\times 4[/tex]
[tex]5x=60[/tex]
Divide both sides by 5.
[tex]x=12[/tex]
Therefore, the remaining number of slices of pie is 12.

In the figure, BE||CD, B is the midpoint of AC, and E is the midpoint of AD
Answer:
A. 8
Step-by-step explanation:
BE = ½(CD) (midsegment theorem)
BE = 2x - 10
CD = 12
Plug in the values
2x - 10 = ½(12)
2x - 10 = 6
Add 10 to both sides
2x - 10 + 10 = 6 + 10 (addition property of equality)
2x = 16 (addition property of equality)
Divide both sides by 2
2x/2 = 16/2
x = 8 (division property of equality)
