The expression which represents how much money all three women make together, given they work the same number of weeks is (1,650w + 200)
Algebraic expressionNumber of weeks = wAmount Jenna make per week = $450Amount Julia make per week = $450Bonus Jenna receives = $100Bonus Julia receives = $100Amount Sara makes per week = $750Total mount Jenna makes = 450w + 100Total mount Julia makes = 450w + 100Total mount Sara makes = 750wTotal amount all three women make together = (450w + 100) + (450w + 100) + (750w)
= 450w + 100 + 450w + 100 + 750w
= 1,650w + 200

While sorting some change into piggy banks, Kyle put 4 coins in the first piggy bank, 6 coins in the second piggy bank, 9 coins in the third piggy bank, 13 coins in the fourth piggy bank, and 18 coins in the fifth piggy bank. If this pattern continues, how many coins will Kyle put in the sixth piggy bank?
Answer:24
Step-by-step explanation:4+2=6,6+3=9,9+4=13,13+5=18,18+6=24
Answer:
24
Step-by-step explanation:
because in first piggy bank has 4 coins and second has 6 . difference=6-4=2
second has 6 coins and third has 9 . difference= 9 - 6 = 3 third has 9 coins and fourth has 13 . difference=13-9=4
fourth has 13 and fifth has 18 coins difference is 18 -13 =5
then,sixth has 24 because all have 2 3 4 5 difference then six has 6

Firslty, we need to find the function, whcih we can do by substituting one into the other:
[tex]f(g(x))=2(g(x))^2-1=2(\sqrt[]{x-2})^2-1=2(x-2)-1=2x-4-1=2x-5[/tex]Now, for the domain we have more complicated approach.
We first have to find the domain for both f(x) and g(x).
The domain of f(x) is all real number, because it is a quadratic polynomial.
The domain of g(x) is all the real numbers except the x values that makes the square root interior negative, so all real numbers so that:
[tex]\begin{gathered} x-2\ge0 \\ x\ge2 \end{gathered}[/tex]Now, the domain of the composite function f(g(x)) is the set of all the values of x in the domain of g(x) such that the corresponding g(x) is in the domain of f(x).
Since the domain of f(x) is all real numbers and g(x) is a real number function, all the values of g(x) will be in the domain of f(x), so we just need to check the values of x that are in the domain of g(x).
The domain of g(x), as we saw, is:
[tex]D=\mleft\lbrace x\mright|x\ge2\}[/tex]And any value of x will give a g(x) that will be in the domain of f(x) so, the domain of f(g(x)) is:
[tex]D=\mleft\lbrace x\mright|x\ge2\}[/tex]So, the correct alternative is:
[tex]\begin{gathered} f(g(x))=2x-5 \\ D\colon\mleft\lbrace x\mright|x\ge2\} \end{gathered}[/tex]If g(x) = x² + 2, find g(3).

Ryan collected 2,650 baseball cards, football cards, and hockey cards. he has 3 times as many baseball cards as football cards. he has 150 more hockey cards than football cards. how many baseball cards does he have? ryan has baseball cards.
The calculated answer after simplification in which Ryan has number of baseball cards is: 357 cards
How to simplify statement problems?
In mathematics, the statement based problems can be solved by forming the equations. And later, simplify those equation by equating to each other. This method is very common for the complicated problems to make the calculation easy.
According to the question, Ryan collected 2650 cards. In which, he has more baseball cards compared to football cards.
Now, let us assume, baseball cards be 'B'; football cards be 'F' and hockey cards be 'H'.
As per the question, the formed equation from the statement for the simplification is:
B + F + H = 2650
3B = F and H + 150 = F
Substituting above values in the formed equation to get the simplify answer,
B + 3B + 3B - 150 = 2650 ⇒ 7B = 2500 ⇒ B = 357
Now, the value of football cards is: F = 3(357) = 1071
And, the value of hockey cards is: H = 1071 - 150 = 921
Hence, after simplification Ryan has number of baseball cards is: 357 cards

Two angles are complementary. If one angle is (x²-16x) and the other is (3x), thenwhat is the measures of the angles?
The smaller angle =
The larger angle =
Answer:
Complementary angles have a sum of 90°.
(x²-16x)+(3x) = 90
x² -13x - 90 = 0
(x-18)(x+5) = 0
x - 18 = 0 or x + 5 = 0
x = 18 or x = -5 (reject)
Substitute x into the angles.
18²-16(18) = 36
Smaller angle = 36°
3(18) = 54
Larger angle = 54°

The equation representing the pool draining in slope-intercept form is y = -12x + 38000 and the time for the pool to fully drain is 3167 minutes.
What is a linear equation?It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.
The equation is referred to as a linear equation in one variable if just one variable is contained in the linear equation.
As we know,
The standard form of the straight line is:
y = mx + b
The slope in this case is m, and the y-intercept is b.
From the data given:
y = -12x + 38000
Plug y = 0 to find how long it will take for the pool to fully drain:
0 = -12x + 38000
x = 3167 minutes
To fill it back up, the y-intercept is 0.
The slope is given M = 16
y = 16x
Now plug y = 38000 to find how long it will take for the pool to fill back up
38000 = 16x
x = 2375 minutes
Thus, the equation representing the pool draining in slope-intercept form is y = -12x + 38000 and the time for the pool to fully drain is 3167 minutes.

The volume, V, of a container is directly proportional to the cube of its height, h. When its height
is 4 cm, its volume is 48 cm3.
1.What is the volume if the height is 3 cm?
2.If the height is doubled to 6 cm, how many times bigger will the volume be?
Answer:
see explanation
Step-by-step explanation:
given that V is directly proportional to h³ , then the equation relating them is
V = kh³ ← k is the constant of proportion
to find k use the condition V = 48 when h = 4 , then
48 = k × 4³ = 64k ( divide both sides by 64 )
[tex]\frac{48}{64}[/tex] = k , then k = 0.75
V = 0.75h³ ← equation of proportion
1
when h = 3 , then
V = 0.75 × 3³ = 0.75 × 27 = 20.25 cm³
2
when h = 6 , then
V = 0.75 × 6³ = 0.75 × 216 = 162 cm³
then
162 ÷ 20.25 = 8
the volume will be 8 times bigger

Derek says the dilation was a reductionDelilah says the dilation was an enlargement who is correct and why
Delilah is correct; it is
Here, we want to check who was right
Mathematically, we can dilate a figure by reduction or enlargement by the use of a specific scale factor
When the scale factor is less than 1, it is a reduction
However, if the scale factor is greater than 1, it is an enlargement
The original point is (x,y)
From the image coordinates given, we see that the scale factor is 6/5 which is greater than 1
Thus, the dilation is an enlargement and Delilah was right

Use the figure shown. Let point D be at (-4,1) . Use the sides of triangle BDA to find the slope of the line.
The slope of the line shown in the figure having equation x + 2y = 0 is 1/2.
The point A is at ( -2 , 1 ), point B is at ( -4 , 2 ) and Point C is at ( -2 , 2 ).
Let point D be at ( -4 , 1 ).
Now the new triangle is ΔBDA and the corner points are A is at ( -2 , 1 ), point B is at ( -4 , 2 ) and point D is at ( -4 , 1 ).
The equation of line passing through two points is given by:
[tex](y-y_{1} ) = (\frac{y_{2}-y_{1} }{x_{2} - x_{1} })(x - x_{1} )[/tex]
The equation of line passing through two points A( -2 , 1 ) and B( -4 , 2 ) IS

where:
p and q are the x-intercepts.a is some constant.Given x-intercepts:
(3, 0)(9, 0)Substitute the given x-intercepts into the formula:
[tex]\implies y=a(x-3)(x-9)[/tex]
To find a, substitute the given point (10, -7) into the equation and solve for a:
[tex]\implies a(10-3)(10-9)=-7[/tex]
[tex]\implies a(7)(1)=-7[/tex]
[tex]\implies 7a=-7[/tex]
