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
Can someone help me please
Answer: it should be x
Step by step explanation: the x table changes at a rate of 6 when the y table changes at a rate of 4

The equation that represents Runner #2 is t = 8.5d where t is time (in minutes) and d is distance in miles). If
Runner #2 runs 2 miles, how many minutes will it take?
Answer:
17minutesStep-by-step explanation:
Given the equation of the time t = 8.5d took by aa runner to ru n. If the runner ran 2 miles, to calculate the time take by the runner to run two miles, we will substitute d = 2 into equation and calculate t as shown;
t = 8.5d
t = 8.5(2)
t = 17.0 minutes
Hence it will take the runner 17minutes to run 2 miles.
Runner #2's equation is an illustration of proportional equations
It will take runner #2 17 minutes to run 2 miles
Runner #2's equation is given as:
[tex]\mathbf{t = 8.5d}[/tex]
When runner #2 runs two miles, it means that:
d = 2
Substitute 2 for d in the given expression.
So, we have:
[tex]\mathbf{t = 8.5 \times 2}[/tex]
Multiply
[tex]\mathbf{t = 17}[/tex]
Hence, it will take runner #2 17 minutes to run 2 miles

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
Find the length of the missing side. Leave your answer in simplest
radical form. *
Answer:
About 14
Step-by-step explanation:
For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)
The sides that make the right angle are legs which is A and B
The other side is the hypotenuse which is C
So you set it up as
11(11) + b(b) = 18(18)
121 + b(b) = 324
324 - 121 = 203
so b(b) = 203
but 203 is b squared so you need to find the square root of 203 which is about 14.2478.
If you round that it is 14
Check
11(11) + 14(14) = 18(18)
121 + 196 = 324
317 = 324

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.

All direct proportion equations are in the form y = kx, for some fixed number k.
If we had y = 17x, without the 2 at the end, then it would be in the form y = kx with k = 17. In other words, y = 17x is a direct proportion equation.
The 2 at the end is why we don't have a direct proportion equation. The y intercept must be 0. All direct proportion equations go through the origin.
