what question?????????????????
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.
what does this mean
Answer:
it means to add all of the numbers then divide by how many there are
so, 3+3+5+5+5+7+7+8+15+15=73
73/10=7.3

The Roaming Cell Phone Company charges $15.00 per month plus $0.20 per minute of
airtime usage. If Juanita uses x minutes of airtime, what is an equation that can be
used to determine her monthly cell phone bill (C)?
C = 15 + 0.20%
C =15 (0.20%)
C# 15 + X+ 0.20

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

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

An object with a mass of 5.0kg accelerates 8.0m/s2 when an unknown force is applied to what is the force?
Answer:
The correct amount of force i believe is
f= 40 newton
i got the answer by using the formula below
force = mass x acceleration
f=5kg *8.0 m/s^2

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.

Find the value of x.
Answer:
X = 66°Step-by-step explanation:
ΔH + ΔJ + ΔK + ΔG = 360°
103° + 133° + 58° + X = 360°
294° + X = 360°
X = 360° - 294°
X = 66°

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.
