Mary has been saving her weekly allowance for the past 20 weeks. She started with $100 and now has $300. Which equation can be used to find the amount of money Mary receives for her weekly allowance?
Answer:
Step-by-step explanation:
You should set this up as an y = mx + b equation. Since 300 is her final number, that will be your y value. She started with 100, so that will be your b value. 20 is the number related to the variable you don't know so that will be your m.
300 = 20x + 100
-100 -100
200 = 20x
divide both sides by 20
10 = x
The period of a pendulum is the time the pendulum takes to swing back and forth. The function L=0.81t^2 relates the length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 110 feet long. Find the period.
Answer:
11.73seconds
Step-by-step explanation:
Given the expression of length L in feet of a pendulum to the time t in seconds that it takes to swing back and forth modeled as;
L = 0.81t²
Given
Length of the pendulum = 110feet
Required
Time (period)
Substitute the given value into the formula
L = 0.81t²
110 = 0.8t²
t² = 110/0.8
t² =137.5
t = √137.5
t = 11.73seconds
Hence the period is 11.73seconds
Draw a model to help solve 5/6 + 1/4. write ur answer as a mixed number.
The required simplified solution of the given expression in the form of a mixed number is 1 1/12.
Given that,
To determine the solution of expression 5/6 + 1/4. in the form of a mixed number.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
= 5 / 6 + 1 / 4
= [ 5×4 + 1×6 ] / [6×4]
= 26 / 24
= 13 / 12
= 1 + 1 /12 or 1 1/12
Thus, the required simplified solution of the given expression in the form of a mixed number is 1 1/12.

Which statement is true about function f, which is shown in the graph? f(x) -8x⁵+ 4x³+5x?
A. Function f is neither even nor odd.
B. Function f is even.
C. Function f is odd.
D. function f is both even and odd.
Answer:
f(-x)=-f(x)
So, Function f is odd
Option C is correct.
Step-by-step explanation:
Which statement is true about function f, which is shown in the graph?
f(x)= -8x⁵+ 4x³+5x?
Function is even if f(-x)= f(x)
and function is odd if f(-x)=-f(x)
Putting x=-x and finding f(-x)
f(-x)=-8(-x)^5+4(-x)^3+5(-x)
f(-x)=-8(-x^5)+4(-x^3)-5x
f(-x)=+8x^5-4x^3-5x
f(-x)=-(-8x^5+4x^3+5x)
f(-x)=-f(x)
So, Function f is odd
Option C is correct.
The function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = -8x⁵+ 4x³+5x
Plug x → -x
f(-x) = -8(-x)⁵+ 4(-x)³+5(-x)
f(-x) = 8x⁵- 4x³-5x
f(-x) = -( -8x⁵+ 4x³+5x)
f(-x) = -f(x) (condition for odd function)
Thus, the function f(x) = -8x⁵+ 4x³+5x is an odd function option (C) Function f is odd is correct.

Which is true about the polynomial –3xy2 + 5x?y?
It is a binomial with degree 3
Explanation:
It has two terms: (−3xy2) and (5x2y) → it is a binomial
The degree of an expression is the largest sum of exponents of variables for any term in the expression.
−3xy2=−3x1y2 has a sum of exponents of variables =3
5x2y=5x2y1 also has a sum of exponents of variables =3
→ the expression has degree 3

Ronnie made 5 pies for New Year's Day. Some of his family members are allergic to gluten, so he bought gluten-free flour for all of the pies. For each piecrust, he used 2 cups of flour. Health Mart sold bags with 4 cups of gluten-free flour for $12. How much did Ronnie spend on the gluten-free flour so that he had enough for the crusts?
Answer:
He spent $24 dollars
Step-by-step explanation:
Each of the piecrusts had 2 cup of flour he has 5 pies so all pies altogether equally 10 cups so he buys 2 bags for $24 dollars
Step-by-step explanation:
Number of gluten-free flour used for 5 pies= 2×5= 10 cups
cost of 4 cups of gluten-free flour = $12
cost of 1 cup = 12/4 = $3
Then,
cost of 10 cups of gluten-free flour = 3×10
= $30
