Answer:
Eric's statement is false.
Step-by-step explanation:
When a positive and a negative number is added, pay attention to what number has a greater absolute value. If the positive number is greater, then the answer will be positive. In the negative number is greater, then the answer will be negative. For example, 23 + (-4) is going to end up as a positive sum, since 23 has a greater absolute value than -4. On the other hand, (-23) + 4 is going to end up as a negative number since -23 has a greater absolute value than 4.

12x + 6y= 15
- 2x=y+4
Answer:
there is no solution to this problem
Step-by-step explanation:
Answer:
12x + 6y = 15
-2x = y + 4 --------> 0 = 2x + y + 4 ------> -y = 2x + 4 -------> y= -2x -4
12x + 6 ( -2x - 4 ) = 15
12x -12x - 24 = 15
-24 = 15
No solutions
Step-by-step explanation:
-24 does not equal 15 so this problem has no solutions.

what kind of lines are shown in the picture below?
Answers:
A. Parallel
B.intersecting
C. Skew
D.perpendicular
Answer:
B. Intersecting
Step-by-step explanation:
If you were to extend the lines, they would cross eachother
The given lines are intersecting.
What are intersecting lines?When two or more lines cross each other in a plane, they are called intersecting lines. The intersecting lines share a common point, which exists on all the intersecting lines, and is called the point of intersection.
As, from the figure we can see that the line p and q are not parallel to each other because the distance between them is not constant.
Now, the lines are not either skew or perpendicular.
If we extend the lines p and q then will meet at some point which is know as intersecting lines.

Write an equation that represents the transformations formed by the following items:
(a) horizontally shifting the graph 4 units to the left of f(x) = √x and then vertically compression by a factor of 1/3
(b) vertically stretching the graph by a factor of 4 of f(x) = √x and then vertically shifting the graph 3 units up
(c) horizontally stretching the graph of f(x) = √x by a factor of 2 and then vertically shifting the graph 6 units down
Answer:
a) [tex]f(x) = \frac{1}{3} \sqrt{x+4}[/tex]
b) [tex]f(x)=4\sqrt{x} + 3[/tex]
c) [tex]f(x) = 2\sqrt{x} -6[/tex]
Step-by-step explanation:
a) The function will be;
⇒ f (x) = 1/3 √(x + 4)
b) The function will be;
⇒ f (x) = 4√x + 3
c) The function will be;
⇒ f (x) = 2√x - 6
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
There are some transformations are given.
Now,
For (a);
The function is horizontally shifting the graph 4 units to the left of
f(x) = √x.
So, The function become;
f (x) = √(x + 4)
And, Then vertically compression by a factor of 1/3.
So, The function become;
f (x) = 1/3 √(x + 4)
For b:
The function is vertically stretching the graph by a factor of 4 of f(x) = √x.
So, The function become;
f (x) = √x + 3
And, Then vertically shifting the graph 3 units up.
So, The function will be;
⇒ f (x) = 4√x + 3
For c;
The function is horizontally stretching the graph of f(x) = √x by a factor of 2.
So, The function become;
f (x) = 2√x
And, Then vertically shifting the graph 6 units down.
So, The function will be;
⇒ f (x) = 2√x - 6
Thus,
a) The function will be;
⇒ f (x) = 1/3 √(x + 4)
b) The function will be;
⇒ f (x) = 4√x + 3
c) The function will be;
⇒ f (x) = 2√x - 6

Which statement is true about solving absolute value equations
Answer:
This sounds like it's a multiple choice question but you didn't include the possible answers. If it helps, you ignore the sign (negative or positive) of each number in an absolute value equation because the absolute value is essentially the number's distance from zero (for example, the absolute value of 7 is 7, and the absolute value of -7 is also 7 because both the negative and positive number are 7 numbers from 0)
What is m∠A?
Enter your answer in the box.
Answer:
60 degrees
Step-by-step explanation:
sum of interior angles in a triangle is always 180 degrees
find m<E from triangle CED: 43 + m<E + 35 = 180 degrees
m<E = 102 degrees
find m<A: 102 + m<A + 18 = 180
m<A = 60 degrees

Answer:
[tex]f^{-1}(x)=\dfrac{\sqrt[3]{3x+12}}{3}[/tex]
Step-by-step explanation:
For function ...
[tex]y=f(x)[/tex]
sometimes we know y, but we want to find the corresponding value x. That is, we would like to have an inverse function:
[tex]x=f^{-1}(y)[/tex]
Here, I have said the input to the inverse function is the value of y for which we want the corresponding value of x.
__
Normally, we write the inverse function basically the same way we write the function. The input is named x, and the output is named y. We can swap the variable names for input and output either before or after we find the equation that relates them.
Perhaps you can see that finding the inverse function
[tex]x=f^{-1}(y)[/tex]
amounts to solving the function relation y = f(x) for x. If we interchange variables first, it is the same as solving x = f(y) for y.
__
To find the inverse, we can interchange the variables and solve for y.
[tex]x=f(y)=9y^3-4\\\\x+4=9y^3\qquad\text{add 4}\\\\\dfrac{x+4}{9}=y^3\qquad\text{divide by 9}\\\\\dfrac{3x+12}{27}=y^3\qquad\text{make the denominator a cube; multiply by 3}\\\\y=\dfrac{\sqrt[3]{3x+12}}{3}\qquad\text{take the cube root}\\\\\boxed{f^{-1}(x)=\dfrac{\sqrt[3]{3x+12}}{3}}[/tex]
