Solve -2 < 2x + 4 < 12 for x
Answer:
[tex]-3<x<4[/tex]
Step-by-step explanation:
[tex]-2<2x+4<12[/tex]
We want to isolate [tex]x[/tex].
Subtract 4 from all sides:
[tex]-2-4<2x+4-4<12-4[/tex]
[tex]-6<2x<8[/tex]
Divide all sides by 2:
[tex]\frac{-6}{2} <\frac{2x}{2} <\frac{8}{2}[/tex]
[tex]-3<x<4[/tex]
Hope this helped.

A. A worker with 1700 hours of training is paid $40 per month
Step-by-step explanation:
Given : the table of hours of training and monthly pay
To find : meaning of h(40)=1700
Answer : here 40 is given under hours of training and 1700 is given under monthly pay.
So, h(40)=1700 means the workers with 40 hours of training is paid $1700 every month

what is the domain according to the graph?
Answer:
D: [-3, 1]
R: [-4, 0]
Step-by-step explanation:
The domain means what x-values you can input and get a corresponding y-value. In this case, on the graph, there are x-values from x = -3 to x = 1, and all of those have corresponding y-values. If you look at x = 2, for example, there's no y-value, so that's not in the domain. So all points from x = -3 to x = 1 are in the domain, and if we put that in interval notation, we get D: [-3, 1].
The range, similarly, is what possible y-values can come out from inputting x-values. In this case, the graph contains y-values from -4 to 0, so the range is R: [-4, 0].

Helloooo:),Is this a function?
Answer: Yes
Step-by-step explanation: It's a fuction because not both of the lines hit the same point on the graph.
How can I reflect this horizontally without a value for h?
Answer:
Another transformation that can be applied to a function is a reflection over the x– or y-axis. A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis. The reflections are shown in Figure 9.
Graph of the vertical and horizontal reflection of a function.
Figure 9. Vertical and horizontal reflections of a function.
Notice that the vertical reflection produces a new graph that is a mirror image of the base or original graph about the x-axis. The horizontal reflection produces a new graph that is a mirror image of the base or original graph about the y-axis.
A GENERAL NOTE: REFLECTIONS
Given a function \displaystyle f\left(x\right)f(x), a new function \displaystyle g\left(x\right)=-f\left(x\right)g(x)=−f(x) is a vertical reflection of the function \displaystyle f\left(x\right)f(x), sometimes called a reflection about (or over, or through) the x-axis.
Given a function \displaystyle f\left(x\right)f(x), a new function \displaystyle g\left(x\right)=f\left(-x\right)g(x)=f(−x) is a horizontal reflection of the function \displaystyle f\left(x\right)f(x), sometimes called a reflection about the y-axis.
HOW TO: GIVEN A FUNCTION, REFLECT THE GRAPH BOTH VERTICALLY AND HORIZONTALLY.
Multiply all outputs by –1 for a vertical reflection. The new graph is a reflection of the original graph about the x-axis.
Multiply all inputs by –1 for a horizontal reflection. The new graph is a reflection of the original graph about the y-axis.
EXAMPLE 7: REFLECTING A GRAPH HORIZONTALLY AND VERTICALLY
Reflect the graph of \displaystyle s\left(t\right)=\sqrt{t}s(t)=√
t
(a) vertically and (b) horizontally.
SOLUTION
a. Reflecting the graph vertically means that each output value will be reflected over the horizontal t-axis as shown in Figure 10.
Graph of the vertical reflection of the square root function.
Figure 10. Vertical reflection of the square root function
Because each output value is the opposite of the original output value, we can write
\displaystyle V\left(t\right)=-s\left(t\right)\text{ or }V\left(t\right)=-\sqrt{t}V(t)=−s(t) or V(t)=−√
t
Notice that this is an outside change, or vertical shift, that affects the output \displaystyle s\left(t\right)s(t) values, so the negative sign belongs outside of the function.
b.
Reflecting horizontally means that each input value will be reflected over the vertical axis as shown in Figure 11.
Graph of the horizontal reflection of the square root function.
Figure 11. Horizontal reflection of the square root function
Because each input value is the opposite of the original input value, we can write
\displaystyle H\left(t\right)=s\left(-t\right)\text{ or }H\left(t\right)=\sqrt{-t}H(t)=s(−t) or H(t)=√
−t
Notice that this is an inside change or horizontal change that affects the input values, so the negative sign is on the inside of the function.
Note that these transformations can affect the domain and range of the functions. While the original square root function has domain \displaystyle \left[0,\infty \right)[0,∞) and range \displaystyle \left[0,\infty \right)[0,∞), the vertical reflection gives the \displaystyle V\left(t\right)V(t) function the range \displaystyle \left(-\infty ,0\right](−∞,0] and the horizontal reflection gives the \displaystyle H\left(t\right)H(t) function the domain \displaystyle \left(-\infty ,0\right](−∞,0].
TRY IT 2
Reflect the graph of \displaystyle f\left(x\right)=|x - 1|f(x)=∣x−1∣ (a) vertically and (b) horizontally.
Solution
EXAMPLE 8: REFLECTING A TABULAR FUNCTION HORIZONTALLY AND VERTICALLY
A function \displaystyle f\left(x\right)f(x) is given. Create a table for the functions below.
\displaystyle g\left(x\right)=-f\left(x\right)g(x)=−f(x)
\displaystyle h\left(x\right)=f\left(-x\right)h(x)=f(−x)
\displaystyle xx 2 4 6 8
\displaystyle f\left(x\right)f(x) 1 3 7 11
SOLUTION
For \displaystyle g\left(x\right)g(x), the negative sign outside the function indicates a vertical reflection, so the x-values stay the same and each output value will be the opposite of the original output value.
\displaystyle xx 2 4 6 8
\displaystyle g\left(x\right)g(x) –1 –3 –7 –11
For \displaystyle h\left(x\right)h(x), the negative sign inside the function indicates a horizontal reflection, so each input value will be the opposite of the original input value and the \displaystyle h\left(x\right)h(x) values stay the same as the \displaystyle f\left(x\right)f(x) values.
\displaystyle xx −2 −4 −6 −8
\displaystyle h\left(x\right)h(x) 1 3 7 11
TRY IT 3
\displaystyle xx −2 0 2 4
\displaystyle f\left(x\right)f(x) 5 10 15 20
Using the function \displaystyle f\left(x\right)f(x) given in the table above, create a table for the functions below.
a. \displaystyle g\left(x\right)=-f\left(x\right)g(x)=−f(x)
b. \displaystyle h\left(x\right)=f\left(-x\right)h(x)=f(−x)

Whats the slope of the line from these 2 points
(14,0) and (4,-5) type an interger or a simplified fraction.
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (14, 0 ) and (x₂, y₂ ) = (4, - 5 )
m = [tex]\frac{-5-0}{4-14}[/tex] = [tex]\frac{-5}{-10}[/tex] = [tex]\frac{1}{2}[/tex]
A linear function that contains the points (3,9) and (12, 12).
point-slope form:
slope-intercept form:
Answer:
Point-slope form: y - 9 = 1/3 (x - 3)
y-intercept form = 1/3x + 8
Step-by-step explanation:
Slope = (12-9)/12-3) = 3/9 = 1/3
Point-slope form:
y -9 = 1/3(x - 3)
y-intercept form
y - 9 = 1/3x -1
y = 1/3x - 1 + 9
y = 1/3x + 8
Point-slope form: y - 9 = 1/3 (x - 3) and y-intercept form = 1/3x + 8.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
The slope of the line will be calculated by the formula below:-
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = (12-9)/12-3) = 3/9 = 1/3
Point-slope form:-
y -9 = 1/3(x - 3)
y-intercept form:-
y - 9 = 1/3x -1
y = 1/3x - 1 + 9
y = 1/3x + 8
Therefore, point-slope form: y - 9 = 1/3 (x - 3) and y-intercept form = 1/3x + 8.

Step-by-step explanation:
35.95 with a 20% discount.
You can do this the straight forward way. Take 20% 35.95
20/100 * 35.95 = 7.19
Now subtract this from 35.95
35.95 - 7.19 = 28.76
15/100 * 29.75 = 4.46
29.75 - 4.46 = 25.28
25% * 38.49 = 9.62
38.49 - 9.62 = 28.86
