The line m has a slope of 4. What is the slope of a line perpendicular to line m?
Step-by-step explanation:
Given
Slope (m1) = 4
As it is said that the lines are perpendicular so we have
m1 * m2 = - 1
4 * m2 = - 1
m2 = - 1/4
The slope of the line perpendicular to line m is
- 1/4
Hope it will help :)❤
Answer:
The slope of the perpendicular line is -1/4
Step-by-step explanation:
Perpendicular lines have slopes that multiply to -1
Let the slope of the perpendicular line have sloe p
m*p = -1
4 * p = -1
Divide each side by 4
p = -1/4
The slope of the perpendicular line is -1/4

Hello There!
So the sum of the cakes (y) and cookies (x) is 64
so x + y = 64
It says that the amount of cookies he sold was 4 less then 3 times the number of cakes he sold
x = cookies
y = cakes
he sold 3 times the amount of cakes (y) - 4
so x=3y-4
So we can conclude that the answer would be D

plugged in the answers into (x) and (y)
The points (0, 0), (-1, -1), and (1,-2) inside the conic inequality option (B), (C), and (E) are correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
Conic inequality:
8x² – 12x + 4y² + 4y – 20 ≤ 0
After plotting the above inequality on a coordinate plane we will get an ellipse:
From the graph:
The points:
(0, 0), (-1, -1), and (1,-2) inside the conic inequality.
Thus, the points (0, 0), (-1, -1), and (1,-2) inside the conic inequality option (B), (C), and (E) are correct.

A) Find the Volume enclosed by the curve =6−22 and the x-axis when it is rotated once around the x-axis.
Answer:
hello your question is not well written hence i will give you a more general answer assuming a region that is enclosed by curves y = x and y = x^3
answer : 8/21
Step-by-step explanation:
y =x , y = x^3
next determine the intersection point which is
x = x^3
x( x^2 - 1 ) = 0
therefore ; x = 0 , 1 , -1

I need help , I really don’t understand it .
Answer:
slope intercept form is the form of y=mx+b, where the slope is m and the y intercept is b.
what you have to do is to solve the equations for y.
1) 2x+2y = 10
2y = 10 -2x
y = -x +5
2) 12+4y = -4x
4y = -4x-12
y = -x -3
lines are parallel when they have same slope and different y-intercepts. m1=m2 and b1 ≠ b2
lines are perpendicular when the multiplication of their slope gives -1
m1 x m2 = -1
here the slopes are same and y-intercepts are different so lines are parallel.

The table shows the height of water in a pool as it is being filled. A table showing Height of Water in a Pool with two columns and six rows. The first column, Time in minutes, has the entries, 2, 4, 6, 8, 10. The second column, Height in inches, has the entries, 8, 12, 16, 20, 24. The slope of the line through the points is 2. Which statement describes how the slope relates to the height of the water in the pool?
A. The height of the water increases 2 inches per minute.
B.The height of the water decreases 2 inches per minute.
C. The height of the water was 2 inches before any water was added.
D. The height of the water will be 2 inches when the pool is filled.
Answer:
A. The height of the water increases 2 inches per minute.

Find the value of x please and thank you
Given:
In triangle DEF, HG is parallel to DF.
To find:
The value of x.
Solution:
In triangles DEF and GEH,
[tex]\angle DE F\cong \angle GEH[/tex] (Common angle)
[tex]\angle EDF\cong \angle EGH[/tex] (Corresponding angle)
[tex]\Delta DE F\sim \Delta GEH[/tex] (By AA property of similarity)
We know that corresponding sides of similar triangle are proportional.
[tex]\dfrac{DE}{GE}=\dfrac{DF}{GH}[/tex]
[tex]\dfrac{9+(x+5)}{x+5}=\dfrac{12}{6}[/tex]
[tex]\dfrac{x+14}{x+5}=2[/tex]
[tex]x+14=2(x+5)[/tex]
[tex]x+14=2x+10[/tex]
Isolating variable terms, we get
[tex]x-2x=-14+10[/tex]
[tex]-x=-4[/tex]
[tex]x=4[/tex]
Therefore, the value of x is equal to 4.
