Which represents a function?
Answers
Answer:
[tex] \boxed{ \text{Option \: D}}[/tex]
Step-by-step explanation:
All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called vertical line test.
If the vertical line intersects the graph of a relation at one point , the relation is a function .If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.--------------------------------------------------
Let's check all of the options :
☐ Option A :
The vertical line cuts the graph at two points. So , the graph does not represent a function.☐ Option B
No! This is also not a function as the vertical line cuts the graph at two points.☐ Option C
Nah! This too can't be called a function as the vertical line cuts the graph at two points.☑ Option D
Yep! The vertical line cuts the graph at one point. Thus , the graph represents a function.Yayy!! We found our answer. It's ' Option D '.

Find x and y
Answer:
[tex]x = 4[/tex]
[tex]y =2[/tex]
Step-by-step explanation:
Given
[tex]5x-3y=14[/tex] -- (1)
[tex]3x-5y=2[/tex] -- (2)
Required
Find x and y
We'll solve this using elimination method.
Multiply (1) by 3 and (2) by 5 to eliminate x
([tex]5x-3y=14[/tex]) * 3
([tex]3x-5y=2[/tex]) * 5
-------------------------------
[tex]15x - 9y = 42[/tex]
[tex]15x - 25y =10[/tex]
Subtract
[tex]15x - 9y = 42[/tex]
- ([tex]15x - 25y =10[/tex])
-----------------------
[tex]15x - 15x - 9y + 25y = 42 - 10[/tex]
[tex]- 9y + 25y = 42 - 10[/tex]
[tex]16y = 32[/tex]
Make y the subject
[tex]y = \frac{32}{16}[/tex]
[tex]y =2[/tex]
Substitute 2 for y in [tex]5x-3y=14[/tex]
[tex]5x - 3 * 2 = 14[/tex]
[tex]5x - 6 = 14[/tex]
Collect Like Terms
[tex]5x = 14+6[/tex]
[tex]5x = 20[/tex]
Make x the subject
[tex]x = \frac{20}{5}[/tex]
[tex]x = 4[/tex]
Consider a cookie recipe in which 1 1/2 cups of chocolate chips to make cookies. Lara wants to double the number of 25 cookies. How many cups of chocolate chips should she use?
Answers
Answer:
3 cups
Step-by-step explanation:
Double 1.5 to get 3.
Lara would need 3 cups of chocolate chips
The cookie recipe uses of [tex]1\frac{1}{2}[/tex] cups of chocolate chips to make 25 cookies. The ratio of chocolate chips to cookies is [tex]1\frac{1}{2}[/tex] : 25
If Lara wants to double the number of cookies she wants to make, it means she wants to make 50 cookies (25 x 2). In order to determine the cups of chocolate chips that she would need, we also need to double the cups of chocolate chips
Chocolate chips needed = [tex]1\frac{1}{2}[/tex] x 2
Convert the mixed fraction to an improper fraction
3/2 x 2
= 3 cups

z - 4.5 = -1.5
Add 4.5 on both sides
z - 4.5 + 4.5 = -1.5 + 4.5
z = 3
This should be our answer.....and so who did it right?

4. The ratio of the measures of the three angles in a triangle is 7:8:5, what is the
measure of the smallest angle?
Your answer
Answers
Step-by-step explanation:
let the angles be ' 7x, 8x and 5x'
as we know, the sum of all the angles of a triangle is 180 degree, so,
7x + 8x + 5x = 180
20 = 180
x = 180/2
x = 90 degrees
7x = 7 × 90 = 630 degree
8x = 8 × 90 = 720 degrees
5x = 5 × 90 = 540 degrees
therefore, 5x is the smallest degrees

Can the Pythagorean Theorem be used to find a distance in the coordinate plane?
Answers
Answer:
Derived from the Pythagorean Theorem, the distance formula is used to find the distance between two points in the plane. The Pythagorean Theorem, a2+b2=c2 a 2 + b 2 = c 2 , is based on a right triangle where a and b are the lengths of the legs adjacent to the right angle, and c is the length of the hypotenuse.
Step-by-step explanation:

Answer:
He must score an 86 or more on his third test.
Step-by-step explanation:
An average is calculated by the sum of the numbers divided by the total number (#) of numbers (if that makes sense). Knowing this, we can write an algebraic equation in order to find the answer. Let x equal the unknown number.
John's previous test scores and this test score now must be at least an average of 90 or more. Therefore, the equation would be [tex]\frac{86+98+x}{3} \geq 90[/tex]. Isolate x to find the answer:
[tex]\frac{86+98+x}{3}\geq 90\\ \frac{184+x}{3} \geq 90\\184 + x \geq 270\\x \geq 86[/tex]
Therefore, he needs to get at least a 86 or higher.
