Answer:
Two x's can have the same y, but an x cannot have different y's. For example, [(2,3)(-2,4)(3,3)(5,18)] is a function because all of the x's have a specific y, and there is not more than one y to an x. However, [(2,3)(-3,7)(2,-4)] is not a function because one of the x's has more than one y.

Find the measure of the exterior angle.
Answers
Answer: 108 degrees
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the two remote interior angles. (Remote referring to the farthest angles from the exterior angle) 2a = (a+10) + 44. Combine like terms.
2a = a+ 54. Subtract “a” from both sides.
a= 54
You can check for correctness by plugging in 54 for a. 2(54) = (54+ 10) + 44. 108= 108.
(Remember, the exterior angle should equal the sum of the two remote interior angles)

The area of a regular hexagon inscribed in a circle with radius 2 is . Round your answer to the nearest tenth.
Answers
Answer:
10.4 to nearest tenth.
Step-by-step explanation:
If we draw lines from the centre of the circle to each vertex of the hexagon we get 6 equilateral triangles of side length 2.
Altitude of each triangle = sqrt(2^2 - 1^2)
= sqrt3.
So the area of 1 triangle = 1/2 * 2 * sqrt3
= sqrt3
Therefore the area of the hexagon = 6 * sqrt3
= 6sqrt3
= 10.3923

What is a right angle triangle?A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees.
Given that,
In triangle ABC, angle C is a right angle,
Also side AB = 17, BC = 15 and AC =?
To find side AC, use Pythagoreans theorem,
AB² = BC² + AC²
Substitute the values of AB and BC,
17² = 15² + AC²
289 = 225 + AC²
⇒AC² = 289 - 225
⇒AC² = 64
⇒AC = 8
The required length of AC is 8 unit.

Two functions are graphed on the coordinate plane.
On a coordinate plane, a curved line with an upward arc, labeled g of x, crosses the x-axis at (negative 2, 0), and the y-axis at (0, 4). A straight horizontal line, labeled f of x, crosses the y-axis at (0, 4).
Which represents where f(x) = g(x)?
f(4) = g(4) and f(0) = g(0)
f(–4) = g(–4) and f(0) = g(0)
f(–4) = g(–2) and f(4) = g(4)
f(0) = g(–4) and f(4) = g(–2)
Answers
Answer:
Answer:
(B) f(-4)=g(-4) and f(0)=g(0)
Step-by-step explanation:
From the given graph, the lines f(x) and g(x) intersects at two different points.
When x=-4, f(-4)=4 and g(-4)=4
When x=0, f(0)=4 and g(0)=4
Therefore, the points which represent where f(x)=g(x) are:
f(-4)=g(-4); and
f(0)=g(0)

(2)
Total marks: 5
Answers
Answer:
Please check explanations for answer
Step-by-step explanation:
Firstly, we need all the probability in the same decimal form
P(A) = 0.66
P(B) = 0.067
P(C) = 2/3 = 0.67
P(D) = 60/100 = 0.6
a) The least likely is the smallest value of decimal
This is 0.067 which is for coin B
most likely is the highest probability; this is C which is 2/3
b. Probability that D will land on tail is 1 - probability that it lands on head
= 1 - 0.6 = 0.4
c. Mathematically that is the product of the probability and the number of times it was thrown
That will be;
0.066 * 4000
= 264 times

Nayeli wants to earn some extra money so she sells lemonade for $2 per cup and orange juice for $3 per cup. She sells a total of 100 cups and earns $240. Later she wants to find the number of cups of lemonade and the number of cups of orange juice she sold. Which system of equations below represents this situation?
1. 2x + 3y = 240 AND x + y = 100
2. 2x + 3y = 100 AND x + y = 240
3. x + 2y = 100 AND 3x + y = 240
4. 2x + 100 = 240.AND x = 3y
Answers
Answer:
1
Step-by-step explanation:
let x represent lemonade and y represent orange juice
the total earning is $240. 2x+3y=240 allows you to find the number of each cup you need to sell to get $240.
the total number of cups sold is 100. x+y=100 gives you the other equation necessary to find the number of cups of each sold if you told a total of 100

Combine like terms.
6x - 2x = 4x
4x + 8 = 24
Subtract 8 on both sides.

Divide by 4.
x = 4
Answer: x=4
Step-by-step explanation:
Given
2(3x+4)-2x=24
Expand parenthesis
6x+8-2x=24
Combine like terms
4x+8=24
Subtract 8 on both sides
4x+8-8=24-8
4x=16
Divide 4 on both sides
4x/4=16/4
x=4
