How to find the line of reflection on a graph?
Answer:
can you show us the graph
F(x)= x+4
How do you do this step by step?
Answer:
you find the x and y intersepts and draw the line
Step-by-step explanation:
if we break down the equasion in the end it's y=x+4 and from there we can find the intersepts by canceling out, y=x+4 becomes y=4 and 0=x+4 wich is x=-4

3. Identify the function rule from the values in the table
Input Output
output equals input times 4
output equals input minus 6
output equals input plus 10
output equals input plus 6
Answer:
Output equals imput minus 6
Step-by-step explanation:
First, we know that -2 is 1 of the Imputs.
Then we know 8 is the second Output
8 - (-2) so that means it would be minus 6 Imput.

Output equals input times 4 is the function rule from the values in the table.
Looking at the values in the table, we can identify the function rule by analyzing the relationship between the input and output values.
The output values are obtained by applying specific operations to the input values.
Let's examine each statement and see which one matches the given input-output pairs:
Output equals input times -4:
When we multiply the input values by -4, we get the following output values:
[tex]-2 \times -4 = 8[/tex]
[tex]0 \times -4 = 0[/tex]
[tex]1 \times -4 = -4[/tex]
[tex]3 \times -4 = -12[/tex]
This function rule matches the given input-output pairs.
Therefore, the function rule that matches the values in the table is "Output equals input times -4."

A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?
Answer:
The dimensions are:
Length = 5m and Width = 4m
Or
Length = 4m and Width = 5m
Step-by-step explanation:
A rectangular dining room has an area of 20 square meters. It's perimeter is 18 meters. What are the dimensions of the dining room?
Area of a rectangle = Length × Width
= LW = 20 m²
Perimeter of a rectangle =
2L + 2W = 18 m
Hence:
LW = 20...... Equation 1
L = 20/W
2L + 2W = 18 ...... Equation 2
We substitute
20/W for L in Equation 2
2(20/W) + 2W = 18
40/W + 2W = 18
Multiply through by W
40 + 2W² = 18W
2W² - 18W + 40 = 0
2W² - 10W - 8W + 40 = 0
(2W - 8 )(W - 5) = 0
2W - 8 = 0
2W = 8 , W = 8/2 = 4m
W - 5 = 0
W = 5m
W = 4m or 5 m
Solving for L
When W = 5 m
L = 20/W
L = 20/5
L = 4m
When W = 4m
L = 20/W
L = 20/4
L = 5m
Therefore, the dimensions are:
Length = 5m and Width = 4m
Or
Length = 4m and Width = 5m
Solve 12x-5>-2 please
Answer:
[tex]x > \frac{1}{4} [/tex]
Step-by-step explanation:
[tex]12x - 5 > - 2[/tex]
Lets add +5 in both the sides.
[tex] = > 12x - 5 + 5 > - 2 + 5[/tex]
[tex] = > 12x > 3[/tex]
Now lets divide 12 on both the sides.
[tex] = > \frac{12x}{12} > \frac{3}{12} [/tex]

Find the range of the function rule y = 5x – 2 for the domain.
{–1.2, 0, 4}
A.
{–8, –2, 18}
B.
{–4, 2, 22}
C.
{0.16, 0.4, 1.2}
Answer:
A. {–8, –2, 18}
Step-by-step explanation:
y = 5x − 2
x = −1.2 ----> y = 5(−1.2) − 2 = −6 − 2 = −8
x = 0 -----> y = 5(0) − 2 = 0 − 2 = −2
x = 4 -----> y = 5(4) − 2 = 20 − 2 = 18

on spending no more than $160 and
wants to buy at least 5 items.
a. Write a system of linear inequalities
that represents the situation.
b. Graph the inequalities.
Hey there!
Step By Step:
Well so we know that 12 is about half of an 25. So what we are gonna do is to buy 3 of 12$ and 2 of 25$.
3x12=36 and 2x25=50.
With adding those two last numbers, you’ll get $86.

A rectangle has one side that measures 3x + 1 and another that measures 4y + 3. Keith says that the perimeter of the rectangle is 3x + 4y + 4. What is Keith's mistake and what is the correct perimeter of the rectangle?
Answer:
he added the dimensions of the rectangle. He used the wrong formula. the formula he used was length + breadth. He should have multiplied by 2
6x + 8y +8
Step-by-step explanation:
Perimeter of a rectangle = 2 x (L + B)
L = length
b = breadth
2 (3x + 4y + 4. ) = 6x + 8y +8
