Every year Samatha receives a $50 dollar bonus. She also receives $5 For every year that she has been working. Emily receives a $40 bonus She also receives $10 for every year that she has been working. In 2018 , Samatha worked for 6 years and Emily worked for 2 years. In what year will they both receive the same amount of money?
Answer:
Year 2022
Step-by-step explanation:
Let number of years = x
Samantha :
Bonus + yearly earning
50 + 5x
Emily :
40 + 10x
Curent earning in 2018:
Years worked by Samantha = 6
50 + 5(6) = 50 + 30 = 80
Years worked by Emily = 2
40 + 10(2) = 60
Year when they'll both receive same amount :
80 + 5x = 60 + 10x
5x - 10x = 60 - 80
-5x = - 20
x = 20/5
x = 4 ; x = 4 years
2018 + 4 = 2022
For the given equation, enter the value of M when
x= 3/2
x+2M= 7/2

Answer:
64 meters^2
Step-by-step explanation:
Break the shape into small parts:
The largest rectangle's area is: 5*11 = 55 meters^2
The smaller rectangle's area: 3*3 = 9 meters^2
55 m^2+9m^2 = 64 meters^2
Find the zeroes of the function and write in a+bi form. -(x+1)^2-4=0
Answer:
x = 2 + √-16 [ (-2)⁻¹]
See steps below.
Step-by-step explanation:
Finding the zeroes of a function simply means solving for the unknown variable (in this case "x") when the function is equated to zero.
The function here is [tex]f(x) = -(x + 1)^{2} - 4 = 0[/tex]
Start by opening the bracket. Ignore the minus sign. It will be reintroduced at the end of this step.
(x + 1)(x + 1) = x² + x + x + 1 = x² + 2x + 1
Reintroduce the minus sign. Don't forget to put the result above back in a bracket.
- (x² + 2x + 1) = -x² -2x -1
Place the expression back in the equation and solve. Make sure to put it back in the position where it was.
-x² - 2x - 1 - 4 = 0
Simplify the non-algebraic terms.
-x² - 2x - 5 = 0
Use Quadratic Formula to solve for x.
Quadratic formula: x = -b ± √(b² - 4ac)
2a
a = the coefficient of x² = -1
b = the coefficient of x = -2
c = the unit term = -5
So x = -(-2) ± √ [(-2)² - 4(-1 x -5)]
2(-1)
x = 2 + √-16 or x = 2 - √-16
-2 -2
This is where the evaluation ends, since the square root of minus sixteen cannot be evaluated. x hence is equal to a complex number. The above are the two values for x.
Next step is to put it in "a + bi" form.
x = 2 + √-16 ÷ -2 = 2 + √-16 x (-2)⁻¹
So x = 2 + √-16 [ (-2)⁻¹]
where
a is 2;
b is √-16
i is [(-2)⁻¹]

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the
ranslation?
O(x, y) = (x + 5, y-3)
O (X,Y) - (x + 5, y + 3)
O(x, y) = (x-3, y + 5)
(x, y) = (x + 3, y + 5)
Answer:
A rectangle on a coordinate plane is translated 5 units up and 3 units to the left.
3) O(x,y)=(x-3,y+5)
The rule that describes the translation is (x, y) -> (x - 3, y + 5), the correct option is C.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units:
y=f(x+c) (same output, but c units earlier)
Right shift by c units:
y=f(x-c)(same output, but c units late)
Vertical shift:
Up by d units: y = f(x) + d
Down by d units: y = f(x) - d
Stretching:
Vertical stretch by a factor k: y =[tex]k \times f(x)[/tex]
Horizontal stretch by a factor k: y = [tex]f\left(\dfrac{x}{k}\right)[/tex]
We are given that;
5 units up and 3 units to the left
Now,
In this case, the rectangle is translated 5 units up and 3 units to the left. This means that the vertical shift is 5 and the horizontal shift is -3.
After transformation x=x - 3
Y=y + 5
Therefore, the transforming function will be (x, y) -> (x - 3, y + 5).

The soup pot is 7.5 inches tall with a radius of 4.5 inches. What is the volume of the soup pot?
Answer:
Step-by-step explanation:
the pot will be a cylinder,
V=3.14*r^2*h
V=3.14*(4.5)^2*7.5=476.89
The volume of the soup pot is equal to 476.89 cubic inches.
What is volume?Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of the cube and for the cone it will be radius and height.
The space occupied by the cylinder in three-dimensional space is called the volume of the cylinder.
Given that the soup pot is 7.5 inches tall with a radius of 4.5 inches. The volume of the soup pot will be calculated as,
V=3.14 x r² x h
V=3.14 x (4.5)² x 7.5

to this equation:
4,112 - 5 = 822 remainder 2
CLEAR
Answer:
822 × 5 + 2
Step-by-step explanation:
Given that:
4112 ÷ 5 = [tex]\frac{4112}{5}[/tex]
= 822 remainder 2
To check if the answer is correct, we can write that;
[tex]\frac{4112}{5}[/tex] = 822 remainder 2
4112 = 5 x 822 remainder 2
= 5 x 822 + 2
= 822 x 5 + 2
4112 = 4112
Thus,the correct process of checking the answer is 822 x 5 + 2.

find geometric mean between 2 and 8
Answer: 4
===================================
Rule: The geometric mean of two numbers x and y is sqrt(x*y)
In this case, x = 2 and y = 8
So we have the geometric mean equal to sqrt(2*8) = sqrt(16) = 4
If you wanted to find the geometric mean of three values, then you'll multiply the numbers and take a cube root. If you had four values, then you multiply and apply a fourth root. And so on.

2x - 3y = 26
What is the solution of the system?
0 (-2,3)
(1, -2)
O (-2.4)
(10.-2)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the system of equations
2 + 2y = 6
2x - 3y = 26
Let us solve the system of equations
[tex]\begin{bmatrix}2+2y=6\\ 2x-3y=26\end{bmatrix}[/tex]
Rearrange equations
[tex]\begin{bmatrix}-3y+2x=26\\ 2y=4\end{bmatrix}[/tex]
Multiply -3y+2x=26 by 2: -6y+4x=52
Multiply 2y = 4 by 3: 6y = 12
[tex]\begin{bmatrix}-6y+4x=52\\ 6y=12\end{bmatrix}[/tex]
adding the equations
[tex]6y=12[/tex]
[tex]+[/tex]
[tex]\underline{-6y+4x=52}[/tex]
[tex]4x=64[/tex]
Solve 4x = 64 for x
[tex]4x = 64[/tex]
divide both sides by 4
[tex]\frac{4x}{4}=\frac{64}{4}[/tex]
Simplify
[tex]x = 16[/tex]
For -6y+4x = 52 plug in x = 16
[tex]-6y+4\cdot \:16=52[/tex]
Multiply the numbers: 4 · 16 = 64
[tex]-6y+64=52[/tex]
Subtract 64 from both sides
[tex]-6y+64-64=52-64[/tex]
Simplify
[tex]-6y=-12[/tex]
Divide both sides by -6
[tex]\frac{-6y}{-6}=\frac{-12}{-6}[/tex]
[tex]y=2[/tex]
Therefore, the solution to the system of equations be:
[tex]y=2,\:x=16[/tex]
Thus,
(x, y) = (16, 2)
