I need help with this math question. It is really hard.
What is 2x+20=100
The answer for this math equation is x = 40 or just 40
Step-by-step explanation: You just need to solve this problem in the normal algebraic equation format, applying the rules too.
2x + 20 = 100
2x + 20 - 20 = 100 - 20
2x = 80
2x/2 = 80/2
x = 40
Step 1: Bring 20 to the right side of the equation by subtracting 20 to both sides (subtraction is the opposite of addition and will cancel 20 from the left side and bring it over to the right)
2x + (20 - 20) = 100 - 20
2x + 0 = 80
2x = 80
Step 2: To isolate x divide 2 to both sides (division is the opposite of multiplication and will cancel 2 from the left side and bring it over to the right)
2x ÷ 2 = 80 ÷ 2
x = 40
Check (plug in 40 for x and solve it like normal):
2(40) + 20 = 100
80 + 20 = 100
100 = 100 --------------------------------------> Correct!

Step-by-step explanation:
Let
x------> distance the cat runs before being caught by the dog,
Remember that
The speed is equal to divide the distance by the time
v=d/t
solve for t
t=d/v
so
equate the time
x/24=(200+x)/30
30x=24(200+x)
30x=4,800+24x
30x-24x=4,800
x=4,800/6=800 m
t=d/v=800/24=33.33 sec
or
t=(800+200)/30=1,000/30=33.33 sec

Find the slope of a line given the following points: (-1, 4) and (-5, 4). 0 1 4
Answer:
0
Step-by-step explanation:
The y-coordinates of the points are the same, so it is a horizontal line with a slope of 0.
___
slope = (change in y)/(change in x) = (4 -4)/(-5-(-1)) = 0/-4 = 0
ANSWER
0
EXPLANATION
The slope of a straight line is calculated using the formula:
[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]
The given line passes through (-1,4) and (-5,4).
We substitute the points into the formula to get:
[tex]m = \frac{4 - 4}{ - 5 - - 1} [/tex]
[tex]m = \frac{4 - 4}{ - 5 + 1} [/tex]
This simplifies to:
[tex]m = \frac{0}{ - 4} [/tex]
Zero divided by any number is zero.
Therefore, the slope is:
[tex]m = 0[/tex]

Francine has $4.35 in dimes and quarters. The number of dimes is five more than the number of quarters. How many of each coin does she have?
344676 I hope that helps
Answer:
Franchise has 11 quarters and 16 dimes.
Step-by-step explanation:
Let d represent number of dimes and q represent number of quarters.
We have been given that the number of dimes is five more than the number of quarters. We can represent this information in an equation as:
[tex]d=q+5...(1)[/tex]
We are also told that Francine has $4.35 in dimes and quarters. We can represent this information in an equation as:
[tex]0.10d+0.25q=4.35...(2)[/tex]
Now, we will substitution method to solve linear equations. Upon substituting equation (1) in equation (2), we will get:
[tex]0.10(q+5)+0.25q=4.35[/tex]
[tex]0.10q+0.50+0.25q=4.35[/tex]
[tex]0.35q+0.50=4.35[/tex]
[tex]0.35q+0.50-0.50=4.35-0.50[/tex]
[tex]0.35q=3.85[/tex]
[tex]\frac{0.35q}{0.35}=\frac{3.85}{0.35}[/tex]
[tex]q=11[/tex]
Therefore, Franchise has 11 quarters.
Upon substituting [tex]q=11[/tex] in equation (1), we will get:
[tex]d=11+5[/tex]
[tex]d=16[/tex]
Therefore, Franchise has 16 dimes.
the two figures are similar. write the similarity. justify your answer.
Answer:
The corresponding sides are in proportion. so they are similar triangles.
The similarity statement is: Triangle ALB ~ Triangle EBR
Similarity statement:
Triangle ALB ~ Triangle EBR
Justification:
Two triangles are similar if they have the same shape, but different sizes. This means that the corresponding angles of the two triangles are equal, and the corresponding sides are proportional.
In the given image, we can see that the two triangles have the same shape. The corresponding angles are also equal:
Angle ALB = Angle EBR
Angle LAB = Angle EBE
Angle BAL = Angle BRE
To show that the corresponding sides are proportional, we can calculate the ratios of the corresponding sides:
AL/EB = 13/5 = 2.6
AB/ER = 15/36 = 5/12 = 0.417
BL/BR = 12/39 = 4/13 = 0.308
We can see that the ratios of the corresponding sides are all equal to 2.6. This means that the corresponding sides are proportional, and therefore the two triangles are similar.
Therefore, the similarity statement is: Triangle ALB ~ Triangle EBR

Find the rectangular coordinates of the point (squareroot3, pi/6)
Answer:
The rectangular coordinates of the point are (3/2 , √3/2)
Step-by-step explanation:
* Lets study how to change from polar form to rectangular coordinates
- To convert from polar form (r , Ф) to rectangular coordinates (x , y)
use these rules
# x = r cos Ф
# y = r sin Ф
* Now lets solve the problem
∵ The point in the rectangular coordinates is (√3 , π/6)
∴ r = √3 and Ф = π/6
- Lets find the x-coordinates
∵ x = r cos Ф
∵ r = √3
∵ Ф = π/6
∴ x = √3 cos π/6
∵ cos π/6 = √3/2
∴ x = √3 (√3/2) = 3/2
* The x-coordinate of the point is 3/2
- Lets find the y-coordinates
∵ y = r sin Ф
∵ r = √3
∵ Ф = π/6
∴ y = √3 sin π/6
∵ sin π/6 = 1/2
∴ y = √3 (1/2) = √3/2
* The y-coordinate of the point is √3/2
∴ The rectangular coordinates of the point are (3/2 , √3/2)

A rectangle 9 cm long is equal in area to a square which has a perimeter of 24 cm,find the width of the rectangle.
The width of the rectangle is 4 cm, found by dividing the area of the square (36 cm^2) by the length of the rectangle (9 cm).
Explanation:To solve the problem we need to first understand two main concepts; the area of a square and the area of a rectangle. The area of a square can be found by squaring the length of one of its sides, which can be described with the formula A = a^2 where a is the side length of the square. Since the perimeter of the square is 24 cm, each side is 24 cm / 4 = 6 cm. Therefore, the area of the square is 6 cm * 6 cm = 36 cm^2.
The area of a rectangle is calculated by the formula A = length * width. We are given that the length is 9 cm and that the area of the rectangle is equal to that of the square, which we found to be 36 cm^2. To find the width, we divide the area by the length: 36 cm^2 / 9 cm = 4 cm. Thus, the width of the rectangle is 4 cm.

Step-by-step explanation:
Consider the formula for the volume [tex]V[/tex] of a cone:
[tex]\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h[/tex],
where
[tex]r[/tex] is the radius of the base of the cone, and[tex]h[/tex] is the height of the cone.For this cone,
[tex]V = 300\;\pi[/tex],[tex]r = 12[/tex], and[tex]h[/tex] is to be found.Rearrange the equation to find the height of this cone.
[tex]\displaystyle V = \frac{1}{3} \pi\cdot r^{2}\cdot h[/tex],
[tex]3\;V = \pi \cdot r^{2}\cdot h[/tex],
[tex]\displaystyle \frac{3\;V}{\pi\cdot r^{2}} = h[/tex].
Therefore,

Consider the functions.
f(x)= square root x
g(x)= square root x-3+1
h(x)= square root x+1-2
Which statement compares the relative locations of the minimums of the functions?
1.The minimums of g(x) and h(x) are both in the first quadrant.
2.The minimums of g(x) and h(x) are both in the third quadrant.
3.The minimum of h(x) is farther right and up from the minimums of f(x) and g(x).
4.The minimum of h(x) is farther left and down from the minimums of f(x) and g(x).
Answer:
The minimum of h(x) is farther left and down from the minimums of f(x) and g(x) ⇒ answer 4
Step-by-step explanation:
* Lets revise the meaning of the minimum of the function
- The minimum of a function is the lowest point of a vertex
- The minimum value is the y-coordinate of the lowest point
* Now lets solve the problem
∵ f(x) = √x
- The domain of the function is all the real numbers ≥ 0, because
there is no square root for negative numbers
- We will use the first value of x to find the range of the function
∵ x = 0 ⇒ first value of the domain
∴ f(0) = √0 = 0
∴ The minimum of f(x) is point (0 , 0)
∵ g(x) = √(x - 3) + 1
- Lets find the domain of the function
∵ x - 3 ≥ 0 ⇒ add 3 for both sides
∴ x ≥ 3
∴ The domain of the function is all real values of x ≥ 3
- We will use the first value of x to find the range of the function
∵ x = 3 ⇒ the first value of the domain
∴ g(3) = √(3 - 3) + 1 = 0 + 1 = 1
∴ The minimum of g(x) is point (3 , 1)
∵ h(x) = √(x + 1) - 2
- Lets find the domain of the function
∵ x + 1 ≥ 0 ⇒ subtract 1 for both sides
∴ x ≥ -1
∴ The domain of the function is all real values of x ≥ -1
- We will use the first value of x to find the range of the function
∵ x = -1 ⇒ the first value of the domain
∴ h(-1) = √(-1 + 1) - 2 = 0 - = -2
∴ The minimum of h(x) is point (-1 , -2)
* To find the correct answer look to the minimum points of the
functions (0 , 0) , (3 , 1) , (-1 , -2)
- The minimum of f(x) lies on the origin
- The minimum of g(x) lies in the 1st quadrant
- The minimum of h(x) lies in the 3rd quadrant
∴ The minimum of h(x) is farther left and down from the minimums
of f(x) and g(x)
- Look to the attached graph to more understand
- The red curve is f(x)
- The blue curve is g(x)
- The green curve is h(x)
Final answer:
The minimums of f(x) and g(x) are in the first quadrant, and h(x) is in the fourth quadrant, making the minimum of h(x) farther right and up from the minimums of f(x) and g(x).
Explanation:
To compare the relative locations of the minimums of the functions f(x) = √x, g(x) = √x - 3 + 1, and h(x) = √x + 1 - 2, we need to consider how transformations affect the graph of the square root function.
The function f(x) is the parent square root function. Its minimum is at the origin (0,0), which is in the first quadrant.
The function g(x) is a horizontal translation 3 units to the right and a vertical translation 1 unit up from the function f(x). Hence, its minimum would also be in the first quadrant.
The function h(x) is a horizontal translation 1 unit to the right and a vertical translation 2 units down from f(x), which places its minimum in the fourth quadrant because the downward translation moves it below the x-axis.
Thus, the correct statement is: 3. The minimum of h(x) is farther right and up from the minimums of f(x) and g(x).
