Answer:
My age is 38 years old
My son is 11 years old
Step-by-step explanation:
Represent my current age with x and my son's current age with y
Two years ago;
[tex]x - 2 = 4 * (y - 2)[/tex]
Eight years ago:
[tex]x - 8 = 10 * (y - 8)[/tex]
Simplify both expressions
[tex]x - 2 = 4 * (y - 2)[/tex]
[tex]x - 2 = 4y - 8[/tex]
Add 2 to both sides
[tex]x - 2 +2= 4y - 8 + 2[/tex]
[tex]x = 4y - 6[/tex]
Substitute 4y - 6 in the second equation
[tex]x - 8 = 10 * (y - 8)[/tex]
[tex]4y - 6 - 8 = 10 * (y - 8)[/tex]
[tex]4y - 14 = 10y - 80[/tex]
Collect Like Terms
[tex]4y - 10y = 14 - 80[/tex]
[tex]-6y = -66[/tex]
Divide through by -6
[tex]y = 11[/tex]
Substitute 11 for y in [tex]x = 4y - 6[/tex]
[tex]x = 4 * 11 - 6[/tex]
[tex]x = 44 - 6[/tex]
[tex]x = 38[/tex]

find the percentage change from the first quantity to the second quantity: from 60 km/h to 45 km/h
Answer:
75%
Step-by-step explanation:
i can't figure it out
Answer:
see explanation
Step-by-step explanation:
Given
x - 6y = 18
To find the x- intercept let y = 0 in the equation and solve for x, that is
x - 0 = 18
x = 18 ← x- intercept ⇒ (18, 0 )
To find the y- intercept let x = 0 in the equation and solve for y, that is
0 - 6y = 18
- 6y = 18 ( divide both sides by - 3 )
y = - 3 ← y- intercept ⇒ (0, - 3 )
Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.
[tex]2 {x}^{2} + x - 1 = 2 [/tex]
Subtract sides -2
[tex]2 {x}^{2} + x - 1 - 2 = 2 - 2 [/tex]
[tex]2 {x}^{2} + x - 3 = 0 [/tex]
[tex](x - 1)(2x + 3) = 0[/tex]

Which equation can you create with the given information? m=6, b=-2 A.) y=6x-2 B.) y=6x+2 C.) y=2x+6 D.) y=-2x-6
Step-by-step explanation:
Hey there!
Your answer is Option A.
Check all:
A. y = 6x-2
Comparing the equation with y = mx+b, we get;
m= 6
and b= -2
B. y= 6x+2
Comparing the equation with y= mx+b, we get;
m = 6
b= 2
C. y = 2x+6
Comparing the equation with y= mx+b, we get;
m= 2
b = 6
D. y= -2x-6
Comparing the equation with y= mx+b, we get;
m= -2
b= -6
Therefore, Option A is correct answer.

I need number 15 and this was cut out: if x=3.
Answer:
x^0/3^2 (^ means to the power) and 3x^-4. The second and last answer choices are the correct answers.
Step-by-step explanation:
1. Solve each problem by plugging in the 3. For (3/x^2)^0, plug in the 3 in replacement of x. Now it is (3/x^2)^0 (3 divided by x squared to the power of 0). 3 squared is equal to 9, and 3/9 is simplified to 1/3. Now the equation is (1/3)^0 (1/3 to the power of 0). 1/3 to the power of 3 is one because any number that has a power of 0 is equal to 1. For the first answer choice, the answer is 1, and 1 is not less the 1, it is equal to 1, so the choice wouldn't be correct.
2. In the second answer choice, x^0/3^2 (x to the power of 0/3 to the power of 2), you first have to first replace the x with a 3. The new equation would be 3^0/3^2 (3 to the power of 0 divided by 3 to the power of 2). Now we have to figure out what 3^0 (x to the power of 0). Since anything to the power of 0 is equal to 1, 3 to the power of 0 would be 1. 3 to the power of 2 is equal to 3 times 3, which equals 9. 1 divided by 9 is equal to 1/9. 1/9 is less than 1 so answer choice number 2 would be correct.
3. In the third answer choice, 1/6^-x (1 divided by 6 to the -x power), you have to plug in the 3 where the x was. Now the equation would be 1/6^-3 (1 divided by 6 to the power of -3). We have to now figure out what 6^-3 (6 to the power of -3). 6^-3 is 1/216. The equation is now 1/1/216, which equals 216, so answer choice number 3 is not correct since 216 is greater than 1 not less than 1.
4. In the fourth answer choice, 1/x^-3 (1 divided by x to the power of -3), you have to substitute x for 3. Now the equation would be 1/3^-3 (1 divided by 3 to the power of -3). Now we have to solve for 3^-3(3 to the power of -3). 3^-3 is 1/27. Now the equation is 1/1/27, which is the same as 27. 27 is not less than 1, so answer choice number four is incorrect.
5. In the fifth answer choice, 3x^-4 (3x to the power of -4), you have to first substitute x for 3. The new equation is 3 × (3^-4). According to PEMDAS, we have to first multiply 3^-4, not 3 times 3. 3^-4 (3 to the power of -4) is equal to 1/81. 3 times 1/81 is equal to 1/27. 1/27 is less than 1 so the answer is correct.
As a result, the second and last answer choices are the correct answers.

Answer:
Yes it is
Step-by-step explanation:
It is a function because it passes the vertical line test
Answer:
If the graph passes the horizontal-line test, then the function is one-to-one. Functions that are one-to-one have inverses that are also functions. Therefore, the inverse is a function.

Identify a line that the rectangle could be reflected over to result in a rectangle that has the same vertices as the original.
Answer:
The correct option is;
y = 6
Step-by-step explanation:
The reflection of the figure of a preimage over a line of symmetry will form an image that the same coordinates as the preimage.
The line of symmetry is a line or axis that goes through the geometric figure's center and outlines the division of the the figure into two identical, symmetrical parts
The appearance of the figure on one side of the line of symmetry is a reflection of the image on the other side of the line of symmetry
In the figure included in the question, given that the shape of the figure is a rectangle the line of symmetry will be a line passing through the midpoint of a chosen side and parallel to the side adjacent to the chosen side
Therefore, the lines of symmetry are x = 4.5 and y = 6. Therefore, the most correct of the given options is y = 6.
Option A will represent the line of reflection.
A rectangle has two pairs of vertices. If one pair reflects over a line in such a way that it replaces the other pair, line is said to be the line of reflection.
If the pair of points A,B replaces the other pair C,D, line of reflection will be y = 6.
Similarly, the pair of vertices A,C replaces other pair B,D, line of reflection will be x = 4.5.
Therefore, line given in Option A will represent the line of reflection.
