the table below does not represent a function why?
Answer:
Because X (10) repeats
Step-by-step explanation:
A function has no repeated X but here in your x variable 10 is there twice so therefore it is NOT a function
You can use the pencil test also in a graph, align your pencil vertically and see if there are multiple points that have the same X and if there isn't any repeated its a function.
Answer:
The function is a relation between two sets that associates to each element of the first set exactly one element of the second set.
We have x = 10 twice with different f(x) associated, 5 and 20.
If we plot those points they will be on same vertical line, thus the vertical line test is failed.
Write an equation of the line that passes through (5,0) and is parallel to the line
y = -3x + 2
Answer:
y=-3x+15
is the equation that passes through the point (5,0) and is the parallel line to y=-3x+2
Step-by-step explanation:
find the slope of the original line and use the point-slope formula y-y₁=m(x-x₁) to find the parallel line of y=-3x+2, which if done correctly you should end up with y=-3x+15.

The coordinates of the point that is a reflection of Y(-4, -2) across the x-axis are (, ). The coordinates of the point that is a reflection of Y across the y-axis are (, ).
Reset Next
Answer: G
Step-by-step explanation:
Data: Point which has the coordinates of (-2.5, 5.5)=x
Only step, find those two coordinates on the table
Explanation: Since the question is asking you to find which point has those two coordinates, all you have to do is instead of finding all the coordinates of the points, just search for the coordinates provided and see what point it lands on.
For this problem, it lands on Point G so the answer is Point G(or just G)

6. A metal is made from copper, zinc and lead in the ratio 13:6:1
respectively. The mass of zinc is 90kg. Calculate the mass of the
metal.
Given:
A metal is made from copper, zinc and lead in the ratio 13:6:1.
The mass of zinc is 90kg.
To find:
The mass of the metal.
Solution:
It is given that the metal is made from copper, zinc and lead in the ratio 13:6:1.
Let the mass of copper, zinc and lead are 13x, 6x and 1x respectively.
The mass of zinc is 90kg. So,
[tex]6x=90[/tex]
[tex]x=\dfrac{90}{6}[/tex]
[tex]x=15[/tex]
Now, total mass of the metal is:
[tex]Total=13x+6x+1x[/tex]
[tex]Total=20x[/tex]
[tex]Total=20(15)[/tex]
[tex]Total=300[/tex]
Therefore, the mass of the metal is 300kg.
Una persona que gana $2460000, invierte 35% en arriendo, 20% en alimentación, 25% en diversión y el resto para los demás gastos. ¿Cuánto dinero le corresponde para los demás gastos?
Answer:
Demas gastos= $492.000
Step-by-step explanation:
Dada la siguiente información:
Una persona que gana $2460000, invierte 35% en arriendo, 20% en alimentación, 25% en diversión y el resto para los demás gastos.
Primero, debemos determinar cuanto gasta en cada item:
Arriendo= 2.460.000*0,35=861.000
Alimentación= 2.460.000*0,20=492.000
Diversión= 2.460.000*0,25= 615.000
Total= $1.968.000
Ahora, lo que gasta en "demás gastos":
Demas gastos= 2.460.000 - 1.968.000
Demas gastos= $492.000

Answer:
m=3
Step-by-step explanation:
add the m on the right side, 4m+3=15
subract the 3 on the left side, 4m=12
divide by four to isolate m, m=3
Answer:
[tex]3m+3=15-m[/tex]
[tex]3m+3=-m+15[/tex]
[tex]3m+m=15-3[/tex]
[tex]4m=12[/tex]
[tex]Divide\ both\ sides \ by\ 4[/tex]
[tex]\frac{4m}{4} =\frac{12}{4}[/tex]

For the triangles to be congruent by HL, what must be the value of x?
2
3
4
7
We have been given two right triangles. We are asked to find the value of x, which will make both triangles similar by Hypotenuse-Leg congruence.
Hypotenuse-Leg theorem states if one leg and hypotenuse of a right triangle is congruent to the one leg and hypotenuse of other right triangle, then both triangles are congruent.
So we can set an equation as:
2x + 1= 9
Upon subtracting 1 from both sides we will get,
2x+1 -1 = 9-1
2x=8
Dividing both sides of our equation by 2 we will get,
x= 4
For the triangles to be congruent by the HL Congruence Theorem, the value of x must be: C. 4.
What is the HL Congruence Theorem?If a leg and the hypotenuse of one right triangle are congruent to a corresponding leg and the hypotenuse of another right triangles, the HL Congruence Theorem states that the triangles are congruent to each other.
Therefore, the two corresponding parts of the right triangles are given as:
2x + 19Thus:
2x + 1 = 9 (HL Congruence Theorem)
Solve for x2x = 9 - 1
2x = 8
x = 4
Therefore, for the triangles to be congruent by the HL Congruence Theorem, the value of x must be: C. 4.

Yolanda makes wooden boxes for a craft fair. She makes 250 boxes as the one shown, and she wants to paint all the outside faces. 6 in.4 in.2 in. Find the surface area of one box. The surface area is square inches.
Answer:
88 square inches
Step-by-step explanation:
Surface Area =2(lw + lh + hw)
Length, l = 6 in
Width, w = 4 in
Height, h = 2 in
Surface Area = 2(lw + lh + hw)
= 2(6*4 + 6*2 + 2*4)
= 2(24 + 12 + 8)
= 2(44)
= 88 square inches
surface area of one box = 88 square inches
An equilateral triangle with side length 20 cm is shown in the diagram, work out the area of the triangle.Give your answer rounded to 1 DP.
Answer:
173.2 cm²
Step-by-step explanation:
Use the equilateral triangle area formula, A = [tex]\frac{\sqrt{3}}{4}[/tex]a²
Plug in the side length and solve:
A = [tex]\frac{\sqrt{3}}{4}[/tex]a²
A = [tex]\frac{\sqrt{3}}{4}[/tex](20)²
A = [tex]\frac{\sqrt{3}}{4}[/tex](400)
A = 173.2
So, the area of the triangle is approximately 173.2 cm²
