Answer:
It's true when x = a positive number.
Step-by-step explanation:
I don't know how to explain this, so here we go.
The definition of absolute value is the distance a number is away from 0.
In other words, all numbers are now positive or 0.
If |-x| = x, it means x would have to be positive because, well, to prove that, we have to see what it couldn't be a negative number
if x was a negative number (-1), this is what we would get
|-(-1)| = -1
|1| = -1
1 = -1
That's not right!
And this happens in any negative number you do.
Because the absolute value of something cannot be negative
I cannot stress that enough
Since it is the absolute value of -x, x has to be positive, if it isn't, then there is no solution for x.
Any number greater than or equal to zero is a possible answer for the absolute value of something, but the absolute value of something cannot be a negative number
I hope this helps, let me know if you have any questions.
Very much struggling with geometry right now, would appreciate the help ❤️
Answer: x= 30
Step-by-step explanation:
These are corresponding angles which means they are equal. (2x+25) = (3x-5). Subtract 2x from both sides. 25 = x-5. Add 5 to both sides. 30 = x

1. Horizontal streets are parallel to each other. The angle measure of the two streets that intersect at Cathy’s Coffee is 95 degrees.
(a) Suppose you are traveling northeast from Ivan’s Ice Cream and turns West at Isabel’s Ice Cream. What is the measure of the angle created by your turning? Explain your answer in terms of what angles are congruent, supplementary, etc. to each other and why.
(b) Suppose you are traveling southwest from Beverly’s Burgers and turn East at Bob’s Burgers. What is the measure of the angle created by your turning? Explain your answer in terms of what angles are congruent, supplementary, etc. to each other and why.
(c) Suppose you are traveling southwest from Beverly’s Burgers and turn West at Connie’s Coffee. What is the measure of the angle created by your turning? Explain your answer in terms of what angles are congruent, supplementary, etc. to each other and why.
Answer:
A)
45 degrees, and it is congruent.
90/2 = 45
Since it is an Alternate Interior, it is congruent.
B)
45 degrees. It is also congruent since it is an Alternate Exterior.
C)
135 degrees. It is a linear angle/linear pair.
180-45=135

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.
Answer:
[tex]10cm^2[/tex]
Step-by-step explanation:
We are given that
Two parallel sides of trapezoid are
[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]
[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]
Height of trapezoid, h=4 cm
We have to find the area of the trapezoid.
We know that
Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]
Where a and b are two parallel sides
h=Height of trapezoid
Using the formula
Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]
Area of trapezoid=[tex]10cm^2[/tex]

Angles 1 and 2 are complementary. If Angle 1 measures 29.6º, then what is the measure of Angle 2? º
Answer:
60.4 degrees

Show work, please!
Answer:
A) 24
B) 24
Step-by-step explanation:
A) equilateral triangle means that all sides are equal
so each side is = 24 because the perimeter = 72
72/3= 24
B) 1 side = 24 and they gave you that 10+7h = 24
so h = 2
so hight of triangle = 2
Area = 1/2(b)(h)
so 24(2)(0.5) = 24

Answer:
13.7ft^2
Step-by-step explanation:
Area for triangle:
The formula for the area of a triangle in this scenario is area=(b*h)/2
The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:
area=(3.6*4.8)/2
area=8.64ft^2 for the triangle
Area for semi-circle:
The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.
The question says to use 3.14 for the value of pi.
The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius
Now, we can just substitute these values into the equation above. So:
area=3.14*(1.8)^2
area=3.14*3.24
area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).
However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:
10.1736/2=5.0868ft^2 for the semicircle.
Total area of shape
Now we have the area of the two separate shapes, we can simply add them together. So:
8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)
Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.
Hope this helped!!

Answer:
x=1/2, y=4
Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2
x=1/2
In ΔDEF, d = 6.4 inches, e = 7.8 inches and ∠F=33°. Find the length of f, to the nearest 10th of an inch.
9514 1404 393
Answer:
4.3 in
Step-by-step explanation:
The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...
f² = d² + e² -2de·cos(F)
f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671
f ≈ √18.0671 ≈ 4.2505
The length of f is about 4.3 inches.

A cylinder has a diameter of 6 cm and a height of 14 cm. What is the approximate volume of a cone with the same diameter and height
as the cylinder?
The approximate volume of a cone with the same diameter and height as the cylinder is 131.95 cm³.
How to calculate the volume of a cylinder?In Mathematics and Geometry, the volume of a cylinder can be calculated by using this formula:
Volume of a cylinder, V = πr²h
Where:
V represents the volume of a cylinder.h represents the height of a cylinder.r represents the radius of a cylinder.Radius = diameter/2 = 6/2 = 3 cm.
By substituting the given parameters into the volume of a cylinder formula, we have the following;
Volume of cylinder, V = π × 3² × 14
Volume of cylinder, V = π × 9 × 14
Volume of cylinder, V = 395.8 cm³.
For the volume of this cone, we have:
Volume of cone, V = 1/3 × πr²h
Volume of cone, V = 1/3 × 395.8
Volume of cone, V = 131.95 cm³.
