Answer: 12
Step-by-step explanation:
This is a direct proportion and we use the formula:
y = kx
If y = −4 when x=2, we need to find the constant of proportionality. This will be:
y = kx
-4 = 2k
k = -4/2
k = -2
To find y when x=−6 guess this:
y = kx
y = -2 × -6
y = 12
Hence, The value of y = 12 when x = -6.
Given that , Y varies directly with x .
If y=−4 when x=2,
Find y when x=−6.
According to the question,
This is a direct variation , y = kx
If,
y = −4 when x=2,
y = kx
-4 = 2k
[tex]k = \frac{-4}{2}[/tex]
k = -2
To find ;
y when x = −6
y = kx
y = (-2) (-6)
y = 12
Hence, The value of y = 12 when x = -6.

Write an equation for the line with slope -5 and point (2,4).
A. y = -5x + 18
B. y = -5x + 6
C. y = -5x + 14
D. Y = -5x - 14
Answer:
I'm not completly sure but im pretty sure its C.
Step-by-step explanation:
A. 1 Substitute y=−18y=−18 into y = x +12 y = x+ 12.− 18 = x +12 −18 = x+12
2 Solve for x x in −18 = x +12 − 18 = x + 12. x = −0 x = −30
3 Therefore, x = −30y = −18 x = −30 y = −18
B. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and
b b is the y-intercept. y = m x + b y = m x +
b Using the slope-intercept form, the slope is 0. m = 0
A. The slope-intercept form is y = m x + b y = m x + b, where m m is the slope and
b b is the y-intercept. y = m x + b y = m x +
b Using the slope-intercept form, the y intercept is 14. b = 14

The simplified form of the given equation is y=x²+2x+1.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
The given equation is y=(x+1)².
Here, by using (a+b)²=a²+2ab+b², we get

The Candy Factory has 30 pounds of fudge. The fudge is sold in 2 1/5 pound boxes. Janie cuts the fudge, and fills as many boxes as possible.
What fractional part of a box remains after filling as many boxes as possible?
Answer:
13 7/11
Step-by-step explanation:
DIVIDE
The fractional part of a box remains after filling as many boxes as possible is 7/11
Given the following:
Amount of pounds of candy factory = 30 poundsIf the fudge is sold in 2 1/5 pound boxes., the number of boxes that can be filled is expressed as:Number of boxes filled = 30 ÷ 2 1/5
Number of boxes filled = 30 * 5/11
Number of boxes filled = 150/11
Number of boxes filled = 13 7/11
Hence the fractional part of a box remains after filling as many boxes as possible is 7/11

4. Lin runs 4 laps around a track in 9 minutes at a constant speed.
A. How many minutes per lap is that? (1 point)
B. How many laps per minute is that? (1 point)
C. How long would it take Lin to run 15 laps at the same rate? (1 point)
Answer:
Number of minutes per lap = 2.25 minute
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 33.75 minutes
Step-by-step explanation:
Given:
Number of laps = 4
Time taken = 9 min
Computation:
Number of minutes per lap = 9 / 4
Number of minutes per lap = 2.25 minute
Number of lap per minute = 4 / 9
Number of lap per minute = 0.444 lap (Approx)
Time taken for 15 lap = 15 x 2.25
Time taken for 15 lap = 33.75 minutes
Solve the equation. -18-6k = 6(1+ 3k) a) k= -2.67 b) k= -1 c) k = 1 d) k = 6
Answer: c) k = 1
Step-by-step explanation:
18 - 6k = 6 + 18k
18 = 6 + 12k
12 = 12k
1 = k
The value of k is -1.
Option B is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 = 7 is an equation.
We have,
-18 - 6k = 6 (1 + 3k)
Solve for k.
-18 - 6k = 6 (1 + 3k)
-18 - 6k = 6 + 18k
-18 - 6 = 18k + 6k
-24 = 24k
k = -24/24
k = -1
Thus,
k is -1.

O B. f-1(x) = +7 +3, where x# 7

O D. f-1(x) = + 3, where x# 3

Note: Your function is missing some information. It seems your function is
[tex]f\left(x\right)=\frac{-3}{x}+7[/tex].
So, I am solving the question based on the function [tex]f\left(x\right)=\frac{-3}{x}+7[/tex], because it would still solve your query.
Answer:
Please see the explanation.
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\frac{-3}{x}+7[/tex]
A function g is the inverse of a function f for y = f(x), x=g(y)
[tex]y=\frac{-3}{x}+7[/tex]
Replace x with y
[tex]x=\frac{-3}{y}+7[/tex]
solve for y
[tex]y=-\frac{3}{x-7}[/tex]
so the inverse of [tex]f\left(x\right)=\frac{-3}{x}+7[/tex] will be:
[tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]
Finding the domain of [tex]f^{-1}\:\left(x\right)=-\frac{3}{x-7}[/tex]
As we know that domain is the set of the possible input values where the function is defined.
so the function domain must be: [tex]x<7\quad \mathrm{or}\quad \:x>7[/tex]
Therefore,
[tex]\mathrm{Domain\:of\:}\:-\frac{3}{x-7}\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x<7\quad \mathrm{or}\quad \:x>7\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:7\right)\cup \left(7,\:\infty \:\right)\end{bmatrix}[/tex]
