Answer:
[tex]2.\ \ (4,6)[/tex]
[tex]4.\ \ (0,0)[/tex]
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Step-by-step explanation:
Given
[tex]y = 1\frac{1}{2}x[/tex]
Required
Determine if the given points is on the graph
First,, we rewrite [tex]y = 1\frac{1}{2}x[/tex] as
[tex]y = \frac{3}{2}x[/tex]
[tex]1.\ \ (1\frac{1}{2},1)[/tex]
This can be interpreted as:
[tex]x = 1\frac{1}{2}[/tex]
[tex]y = 1[/tex]
Substitute [tex]x = 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 1\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{3}{2}[/tex]
[tex]y = \frac{9}{4}[/tex]
This isn't equal to the given value of y.
Hence: [tex](1\frac{1}{2},1)[/tex] is not a point on the graph
[tex]2.\ \ (4,6)[/tex]
Here,
[tex]x = 4[/tex]
[tex]y = 6[/tex]
Substitute [tex]x = 4[/tex]
[tex]y = \frac{3}{2} * 4[/tex]
[tex]y = \frac{3 * 4}{2}[/tex]
[tex]y = \frac{12}{2}[/tex]
[tex]y = 6[/tex]
This point is on the graph
[tex]3.\ \ (18,12)[/tex]
Here,
[tex]x = 18[/tex]
[tex]y = 12[/tex]
Substitute [tex]x = 18[/tex]
[tex]y = \frac{3}{2} * 18[/tex]
[tex]y = \frac{3 * 18}{2}[/tex]
[tex]y = \frac{54}{2}[/tex]
[tex]y = 27[/tex]
This isn't equal to the given value of y.
Hence: [tex](18,12)[/tex] is not a point on the graph
[tex]4.\ \ (0,0)[/tex]
Here, we have
[tex]x = 0[/tex]
[tex]y = 0[/tex]
Substitute [tex]x = 0[/tex]
[tex]y = \frac{3}{2} * 0[/tex]
[tex]y = 0[/tex]
Hence:
This point is on the graph
[tex]5.\ \ (2\frac{1}{2},3\frac{3}{4})[/tex]
Here
[tex]x =2\frac{1}{2}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Substitute [tex]x =2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * 2\frac{1}{2}[/tex]
[tex]y = \frac{3}{2} * \frac{5}{2}[/tex]
[tex]y = \frac{15}{4}[/tex]
[tex]y = 3\frac{3}{4}[/tex]
Hence:
This point is on the graph

A farm stand sells oranges in 3-lb bags for $3.75. What equation represents the cost, c, for p pounds of oranges? Think: how much will 1-lb of oranges cost?
A c = 1.25p B p = 1.25c
C c = 3.75p D p = 3.75c
Answer:
A
Step-by-step explanation:
It’s not B, because it’s saying each pound is 1.25 multiplied by the cost. We are looking for the cost, not the amount of pounds.
it isn’t C, because the oranges are sold in 3 pound bags, and the equation is comparing the cost of a 3 pound bag to 1 pound of oranges.
And it isn’t D, because D does the same thing as B, but with The cost of a 3 pound bag.
An equation is formed of two equal expressions. The correct option is A, c=1.25p.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that the farm stand sells oranges in 3-lb bags for $3.75. Therefore, the cost of the oranges for a pound is,
Cost of a pound of oranges = $3.75 / 3
= $1.25
Now, if the cost,c for p pounds of oranges is,
Cost, c = Cost of a pound of oranges × Number of pounds
= $1.25 × p
c = 1.25p
Hence, the correct option is A, c=1.25p.

Let A, B, and C be any sets. Show that A × (B – C) = (A × B) – (A × C).
Can you help justify the proof
If × denotes the Cartesian product, and if a ∈ A and b ∈ B, then (a, b) ∈ A × B.
First prove that A × (B - C) ⊆ (A × B) - (A × C):
Let a ∈ A and b ∈ B - C.
By definition of the product, (a, b) ∈ A × B.
By definition of complement, b ∈ B and b ∉ C.
So (a, b) ∈ A × B and (a, b) ∉ A × C.
By definition of complement, (a, b) ∈ (A × B) - (A × C).
Therefore, A × (B - C) ⊆ (A × B) - (A × C).
Prove the other direction, that (A × B) - (A × C) ⊆ A × (B - C):
Let (a, b) ∈ (A × B) - (A × C).
By definition complement, (a, b) ∈ (A × B) and (a, b) ∉ (A × C).
By definition of the product, a ∈ A, b ∈ B, and b ∉ C.
By definition of complement, b ∈ B - C.
By definition of the product, (a, b) ∈ A × (B - C).
Therefore, (A × B) - (A × C) ⊆ A × (B - C).
Hence the two sets are equal. QED

Answer:
p=8
Step-by-step explanation:
Find the exact value of cos(a + b), given sin a = 2/5 for a in Quadrant || and cos B = 1/3 for b in Quadrant IV.
Answer:
Option (4)
Step-by-step explanation:
cos(a + b) = cos(a)cos(b) - sin(a)sin(b) [Identity]
Since, sin(a) = [tex]\frac{2}{5}[/tex] for a in quadrant II
Therefore, cos(a) = [tex]\sqrt{1-\text{sin}^2(a)}=\sqrt{1-(\frac{2}{5})^2}[/tex]
cos(a) = [tex]\frac{\sqrt{21}}{5}[/tex]
But cosine of a is negative quadrant II
Therefore, cos(a) = -[tex]\frac{\sqrt{21}}{5}[/tex]
And cos(b) = [tex]\frac{1}{3}[/tex] for b in quadrant IV
Therefore, sin(b) = [tex]\sqrt{1-\text{cos}^{2}b}[/tex]
= [tex]\sqrt{1-(\frac{1}{3})^2}[/tex]
= [tex]\frac{2\sqrt{2}}{3}[/tex]
But sine of an angle is negative in quadrant IV,
Therefore, sin(b) = [tex]-\frac{2\sqrt{2}}{3}[/tex]
Now substituting these values in the identity,
cos(a + b) = [tex](-\frac{\sqrt{21}}{5})(\frac{1}{3})-(\frac{2}{5})(-\frac{2\sqrt{2}}{3})[/tex]
= [tex]-\frac{\sqrt{21}}{15}+\frac{4\sqrt{2}}{15}[/tex]
= [tex]\frac{4\sqrt{2}-\sqrt{21}}{15}[/tex]
Therefore, Option (4) will be the answer.

Step-by-step explanation:
the y intercept is the point where the line crosses the y-axis. given this info, its given that the y intercept would be 5, or (0,5) in coordinates ^_^
Answer:
0,5
Step-by-step explanation:
So this is actually simpler than it looks. All you have to do is see what point starts out with the x coordinate at zero. The center of the graph is 0,0, so the y intercept is 0,5 because that is the first graph of y. The order is 0,5 1,6 2,7 so on and so on. Hope my explanation made sense.

Camila’s box holds 363 balls. Each layer has 33 balls. How many layers does the box have?
Answer:
The box has 11 layers
Step-by-step explanation:
Since there are 363 balls and each layer has 33 balls, we have to divide 363 by 33.
363÷33= 11
So, there will be 11 layers in the box.

Abcd is a cyclic quadrilateral. o is the center of the circle ∠bad = 40°,then angle BCD=?,m(arc BCD) =?,m( arc BAD)=?
Answer:
m∠BCD = 140°
m(arc BCD) = 80°
m(arc BAD) = 280°
Step-by-step explanation:
In the cyclic quadrilateral, every two opposite angles are supplementary.The measure of the subtended arc to an inscribed angle equals twice the measure of this angleLet us use these facts to solve the question
∵ ABCD is a cyclic quadrilateral in circle O
∵ ∠BAD and ∠BCD are opposite angles
→ By using the 1st fact above
∴ m∠BAD + m∠BCD = 180°
∵ m∠BAD = 40°
∴ 40° + m∠BCD = 180°
→ Subtract 40° from both sides
∴ 40° - 40° + m∠BCD = 180° - 40°
∴ m∠BCD = 140°
∵ Arc BCD subtended the inscribed ∠BAD
→ By using the 2nd fact above
∴ m(arc BCD) = 2(m∠BAD)
∵ m∠BAD = 40°
∴ m(arc BCD) = 2(40°)
∴ m(arc BCD) = 80°
∵ Arc BAD subtended the inscribed ∠BCD
→ By using the 2nd fact above
∴ m(arc BAD) = 2(m∠BCD)
∵ m∠BCD = 140°
∴ m(arc BAD) = 2(140°)
∴ m(arc BAD) = 280°.

Originally, Juan borrowed $10, but his mother loaned him $3 more, so he borrowed a total of $13. He sells $25 worth of lemonade in his first week. After Juan pays his mother back the $13 he borrowed, his profit is $12.
If Juan’s mother forgave (or took away) his debt of –13, what equation shows the amount of money Juan will have?
Answer:
25
Step-by-step explanation:
If Juan's mother forgave his debt of -$13, then Juan will have $25 left after paying back his initial loan and making a profit of $12.
Juan's money = $12 + $13
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
If Juan's mother forgave his debt of -$13, then it means that Juan received $13 from his mother instead of owing her $13. So the equation that shows the amount of money Juan will have is:
Juan's profit = Juan's earnings - Juan's expenses
Juan's profit = $25 - $13
Juan's profit = $12
This means that after paying back his loan and making a profit of $12, Juan will have no money left.
If we want to include the amount he initially borrowed, we can modify the equation as follows:
Juan's money = Juan's earnings + Juan's initial loan
Juan's money = $25 - $13 - $13
Therefore, the equation is Juan's money = $12 + $13

I'm pretty sure you multiply first because PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction) says you go left to right and do multiplication or division first, so I would say it'd be multiplication.
