Which equation represents a line which is perpendicular to the line
6x + 7y = -42?
Somebody please help?
Answers
Answer:
y = [tex]\frac{7}{6} x - 5[/tex]
Step-by-step explanation:
Given expression:
6x + 7y = -42
To find an equation perpendicular to this, it implies the slope must be a negative inverse of the given one.
Solution:
Equation of any straight line is given as;
y = mx + c
where x and y are the coordinates
m is the slope
c is the intercept
Let us now find the slope of the line;
6x + 7y = -42
7y = -6x - 42
divide through by 7 to give;
y = [tex]-\frac{6}{7} x[/tex] - 6
The slope is [tex]-\frac{6}{7}[/tex]
A line perpendicular will have a slope of a negative inverse;
- ( [tex]-\frac{7}{6}[/tex] ) = [tex]\frac{7}{6}[/tex]
The answer is A.

What is the inverse of f(x)=x^4 + 7 for x>0 where function g is the inverse of function f
Answers
The first answer
cbjsabcakvscds
The inverse function of the function f(x) will be [tex]\rm g(x) = \sqrt[4]{x - 7}, x \geq 7[/tex]. Then the correct option is A.
What is the inverse function?Let the function f is given as
y = m(x + a) + c
Then the inverse function of the function f will be given by the swapping of x with y and y with x.
The function is given below.
f(x) = x⁴ + 7
The inverse function of f(x) will be
x = [g(x)]⁴ + 7
[g(x)]⁴ = x - 7
[tex]\rm g(x) = \sqrt[4]{x - 7}[/tex]
The function is valid for x ≥ 7.
The inverse function of the function f(x) will be [tex]\rm g(x) = \sqrt[4]{x - 7}, x \geq 7[/tex]. Then the correct option is A.

We have to use pythagorean theorem in finding distance
As given in the attachment, Let AB= 3
BC=4
AC=x
To find AC we use pythagorean theorem
AC²=AB²+BC²
AC²=3²+4²
AC²=9+16
AC²=25
Take square root on both sides.
AC=5
Hence 5 blocks he walks straight back home how far does Jay walk-in all

Answer:
an infinite number of ways
Step-by-step explanation:
The transformation involves a series of reflections, rotations, and translations. Any reflection and translation can be described an infinite number of ways, depending on what you choose for the line of reflection (and how many reflections you choose), and how far you do each translation. Similarly, any rotation can described an infinite number of ways, depending on the amount of rotation and the chosen center point.
So, the answer to the question asked is, "You can describe the movement of the furniture an infinite number of ways."
__
One way to describe it is this:
The upper chair was translated to the right, then reflected* across the horizontal centerline. The couch was rotated 90° about the center of the room and translated upward. The coffee table was rotated -90° about its center and translated to the right.
__
* As a practical matter, a piece of furniture cannot be reflected. It can only be rotated or translated. However, the pillows in the upper chair are moved from the left arm to the right arm, so the appearance is that of a reflection. One might say the chair was rotated 180°, and the pillows were translated.
