Step-by-step explanation:
It could be almost anything.
g(x) = 5*x
g(x) = 5*(x)^2
g(x) = 2.5(2x)
g(x)= 4x *(5/3)
g(x) 10x / 2

4. In preparation for the storm, Mike has printed out some flyers
advertising that he will shovel snow for $15 per hour. Mike also will
charge a minimum of $10.
a. Write an equation to find the total amount charged, y, after x
numbers of hours shoveling snow.
Answer:
y = 10 between 0 and 1
AND
y=15x for x>=1
Step-by-step explanation:
This has 2 segments. One when 0 < x < 1 (y=$10), and one when x >= 1 (y=$15x)
So
y = 10 between 0 and 1
AND
y=15x for x>=1
The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the spring stretches 9 centimeters. Which equation relates the mass of the object, m, and the length of the spring, s?
A s= 3/ 10m
B s= 10/3m
C m=3/10s
D m=1/30s
Answer:
Step-by-step explanation:
I'm assuming that the length of the spring is s and the mass of the object is m. If that be the case, the direct variation equation, which a line btw, is
s = km where k is the constant of proportionality. We have to solve for k, the slope of the line, in order to determine the model for this situation.
9 = k(30) so
[tex]k=\frac{9}{30}=\frac{3}{10}[/tex] Now that we know, the slope of the line, we can rewrite the equation with the slope in place:
[tex]s=\frac{3}{10}m[/tex], choice A.
Ruth is touring New York City with her family. They want to visit the Empire State Building, Central Park, and Times Square before their dinner reservations at 7:10 P.M. They want to spend 1 hour and 25 minutes at the Empire State Building, 2 hours and 5 minutes in Central Park, and 50 minutes in Times Square. What is the latest time Ruth's family can start their tour in order to make it to dinner on time?
Pls help :)
Answer:
The latest time Ruth's family can start their tour in order to make it to dinner on time is 2:50 P.M
Step-by-step
Change:
7h10= 430 mins
1 hour and 25 minutes= 85 mins
2 hours and 5 mintues= 125 mins
- Total time Ruth wants to do before his dinner reservations:
85+ 125+ 50= 260 (mins)
- The latest time Ruth's family can start their tour in order to make it to dinner on time:
430- 260= 170 (mins)
Change: 170 mins= 2 hours and 50 minutes
Good luck!

y=1/3x+5 through (2,1)
Answer:
No solution
Step-by-step explanation:
1 = 1/3(2) + 5
1 = 17/3
1 is not equal to 17/3
so the answer has no solution meaning the point does not exist in the graph.
How do you do this TwT
Answer:
Step-by-step explanation:
First step plug the numbers into the equation.
-10/(5+2) = (-10/5) + (-10/2)
Solve both sides of the equation separately.
-10/(5+2) Use distributive property, multiply both 5 and 2 by -10.
= -50 + (-20) = -70
-10/5 + -10/2 Multiply the fractions so they can be added together.
-10/5*2 = -20/10 -10/2*5 = -50/10
-20/10 + -50/10 = -70
Now you have solved both equations and they are both equal to -70, so you have verified that the equations are equal to each other because they both equal -70.

find LCM of 60,40 and 90
Answer:
Step-by-step explanation:
Prime factorize.
60 = 2 *2 * 3 * 5 = 2² * 3 * 5
40 = 2 * 2 * 2 *5 = 2³ * 5
90 = 2 * 3 * 3 * 5 = 2 * 3² * 5
LCM = 2³ * 3² * 5 = 8 * 9 * 5 = 360
Factorize no g, h, j, k, m, n

The winner of the "Biggest Loser" lost 0.952 ounces per hour. Convert this to pounds per week. There are 16 ounces in one pound
Answer:
10.0 lb/wk ---> final solution
Step-by-step explanation:
There are 7 days in a week right? so ----> 1 week = 7 daysNow, just convert days per week into hours so ----> 7 days × 24 hours = 168 hours168 hours converted to ounce are around 160 ounces =, or 159.9 oz to be more precise. (we convert hours to ounces so we can then find out the answer in pounds)Lastly, convert the ounces you got into pounds so ----> 10 lbs per week4. RE and RD are tangent to circle M.

It is 5 cm between two buildings on a map that has a scale of 100 000:1. What is their actual
distance apart?
O A.
0.5 km
B. 50 km
C.
5 km
OD.
500 km
Answer:
C 5 km
Step-by-step explanation:
so, 5 cm on the map correlates to
5×100000 = 500000 cm in reality.
100 cm = 1 m
1000 m = 1 km
so, 500000 / 100 = 5000 m.
5000 / 1000 = 5 km
Given a positive integer N. Deleting the last digit of N decreases it by 2021. What is N ?
The value of the positive integer N, such that deleting its last digit decreases it by 2021, is 2245. That is, [tex]N=2245[/tex].
Given: A positive integer N such that deleting the last digit of N decreases it by 2021
To find: The value of N
Let x be the integer consisting of all digits of N except the last digit and let the last digit of N be d.
Then, [tex]N=10x+d[/tex]
It is given that deleting the last digit decreases it by 2021
Then, [tex]x=N-2021[/tex]
Substitute [tex]N=10x+d[/tex] in [tex]x=N-2021[/tex] to get,
[tex]x=10x+d-2021[/tex]
[tex]d=2021-9x[/tex]
Since d is a digit, we have,
[tex]0\leq d\leq 9[/tex]
Substitute [tex]d=2021-9x[/tex] in [tex]0\leq d\leq 9[/tex] to get,
[tex]0\leq 2021-9x\leq 9[/tex]
[tex]9x\leq 2021\leq 9x+9[/tex]
[tex]9x\leq 2021\leq 9(x+1)[/tex]
[tex]x\leq \frac{2021}{9} \leq x+1[/tex]
[tex]x\leq 224.5556 \leq x+1[/tex]
Then,
[tex]x\leq 224.5556[/tex] and [tex]224.5556 \leq x+1[/tex]
[tex]x\leq 224.5556[/tex] and [tex]x\geq 223.5556[/tex]
[tex]223.5556 \leq x \leq 224.5556[/tex]
Since x is an integer, the only possibility that satisfies the above inequality is, [tex]x=224[/tex]
Substitute [tex]x=224[/tex] in [tex]d=2021-9x[/tex] to get,
[tex]d=2021-9(224)[/tex]
[tex]d=2021-2016[/tex]
[tex]d=5[/tex]
Substitute [tex]x=224[/tex] and [tex]d=5[/tex] in [tex]N=10x+d[/tex] to get,
[tex]N=2245[/tex]
Thus, the value of the positive integer N, such that deleting its last digit decreases it by 2021, is 2245. That is, [tex]N=2245[/tex].

Answer:
First, find the value of x:
[tex]h(5-x)=h(9)\\5-x=9\\-x=9-5\\-x=4\\x=-4[/tex]
Substitute the x-value in to the function [tex]x^{2}+x+1[/tex] and solve:
[tex](-4)^{2}+(-4)+1=16-4+1=12+1=13[/tex]
Therefore, the value of h(9) = 13.
Hope this is correct O-o
Answer:
A
Step-by-step explanation:
Since we need to find the value of h(9), we can substitute the (5-x) part from the original equation with 9 to get the value of x, which is 5-x = 9, x = -4. With that, we can go ahead and plug the x into the right side of the equation to get (-4)^2 + (-4) + 1, which equals 16 - 4 + 1, which equals 13.

What is the fractional equivalent of the repeating decimal n = 0.1515.... ?
Answer the questions to find out.
1. How many repeating digits does the number represented by n have?
2. You need to multiply n by a power of 10 to help you find the fraction. Decide on the power of 10 to multiply by, and tell how you identified that number.
3. Write an equation where the left side is your power of 10 time n and the right side is the result of multiplying 0.1515... by that power.
4. Write the original equation, n = 0.1515... underneath your equation from question 3. Then subtract the equations. Show your work!
5. Write n as a fraction in simplest form. Show your work!
If n = 0.151515…, then 100n = 15.151515…
Then
100n - n = 15.151515… - 0.151515…
99n = 15
n = 15/99 = 5/33
