Reflect (7,3) across the y-axis.
Then reflect the result across the y-axis again.
What are the coordinates of the final point?
Answer:
(7, 3)
Step-by-step explanation:
If we reflect a point/figure across the y-axis, the rule is (x, y) -> (-x, y).
(7, 3) -> (-7, 3)Now, let's reflect it against the y-axis again.
(-7, 3) -> (7, 3)As you can see, we're back to where we started- at (7, 3). Thus, we can conclude that reflecting across the y-axis twice will result in the original point/figure.
Write the equation that represents the line that goes through the point (5, -7) and has slope m=-3
Answer:
y = -3x + 8
Step-by-step explanation:
Given :-
Point on line = (5, -7)
Slope (m) = -3
To find :-
Equation of line
Solving :-
Using point-slope form of equation,
y - y₁ = m(x - x₁)
y + 7 = -3(x - 5)
y + 7 = -3x + 15
Solution :-
y = -3x + 8

A metal bar is L cm long when its temperature is T◦C. The quantities L and T are
approximately related by the formula L = 0.002T + 25.
L is a function of T and the rule can be written L(T) = 0.002T + 25. State a possible
practical domain for the function.
A possible practical domain for the function is T > 12500
How to find the domain of a functionThe domain are the input values for which a function exist.
Given the function relating the metal bar is L cm long when its temperature is T◦C as:
L(T) = 0.002T + 25
The domain of the expression is the point where 0.002T + 25 is greater than zero.
0.002T + 25 > 0
0.002T > -25
T > 12,500
Hence a possible practical domain for the function is T > 12500

C. n - 4 = 28
D. 1
n = 28
4
Answer:
A

the sum of 2 times a number and 10 is the same as 6 times the difference of the number and 1. what is the numner ?
Answer:
the number is 4
Step-by-step explanation:
let the number be x
2x + 10 = 6(x - 1)
2x + 10 = 6x - 6
minus both sides by 2x
10 = 4x - 6
add both sides by 6
4x = 16
x = 4

Answer:
see below for explanation:-�
Step-by-step explanation:
[tex]: \implies 6x + 2(x - 3) = 4x + x - 18[/tex]
[tex]: \implies{6x + 2x - 6 = 4x + x - 18}[/tex]
[tex]: \implies{8x - 6 = 5x - 18}[/tex]
Add 6 to the both sides:-[tex]: \implies{8x - 6 + 6 = 5x - 18 + 6}[/tex]
[tex]: \implies{8x = 5x - 12}[/tex]
Subtract 5x from both sides:-[tex]: \implies{8x - 5x = 5x - 12 - 5x}[/tex]
[tex]: \implies{8x - 5x = 5x - 5x - 12}[/tex]
[tex]: \implies{3x = 0 - 12}[/tex]
[tex]: \implies{3x = - 12}[/tex]
Divide both sides by 3:-[tex]: \implies{ \displaystyle{ \frac{3x}{3} = \frac{ - 12}{3} }}[/tex]
[tex]: \implies{x = - 4}[/tex]

for the function f(x)= -3x+3 find f(0)
Answer:
3
Step-by-step explanation:
We have been given a function as; f(x)= -3x+3. then it is found that f(0) = 3
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given a function as;
f(x)= -3x+3.
then we need to find the function when x is equal to zero.
If f(x) = -3x + 3, this means that any number that replaces x in the parenthesis, would replace x in the right side too.
When x = 0:
f(0) = -3(0) + 3 = 3
f(0) = 3
Therefore, We have been given a function as; f(x)= -3x+3. then it is found that f(0) = 3
