Kevin went to see his favorite sports team play. His car can go 400 miles on one tank of gas. If he used 30% of a full tank of gas, how many miles did he travel?
(answer this and show your work)
Kevin traveled _answer here_ miles.
(Type an integer or a decimal.)
Answer: 120
120
Step-by-step explanation:
I honestly can’t explain but I think you have to do this (actually I did the work so I’m right)
P/w = part/whole = ?/400
%/100= percent/100 = 30%/100
These numbers are equivalent
If you don’t understand the top then here is how to do the work-
400x30=12000
12000/100=120
Therefore it’s 120
Given f(x)=2^x and g(x)= f(x-3)+4, write the new function rule (equation) for function g and describe (using words) the two transformations that occur between the function f and the function g
*Some good words to consider using would include horizontal, vertical, stretch, compression,
translation, reflection, and phrases such as “to the left”, “to the right”, “up”, “down”, “by a
factor of__, or ”over the __ axis”.
Answer:
Just like Transformations in Geometry, we can move and resize the graphs of functions. Let us start with a function, in this case it is f(x) = x2, but it could be anything: ... g(x) = x2 + C. Note: to move the ... If you change that to (age+4) = 25 then you will get it when you are 21. Adding 4 ... Example: the function v(x) = x3 - x2 + 4x.
Step-by-step explanation:
The graph of the function y = 2x⁴ - 5x³ + x² - 2x + 4 is plotted and attached.
What is a polynomial?Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -
y = 4x⁴ + 3x³ + 2x² + 6x + 7
We have the following polynomial functions -
f(x) = 2ˣ
g(x) = f(x - 3) + 4
We can write g(x) as -
g(x) = 2ˣ ⁻ ³ + 4 = (2ˣ/2³) + 4
g(x) = (2ˣ/8) + 4
The graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards.
Therefore, the graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards to given the function g(x)

Can yall give me 4 examples of rules of exponents with answers pls?
Answer and Step-by-step explanation:
When multiplying two numbers (or variables) of the same exponent, the solution would have the exponents adding each other:
[tex]a^{x} * a^{y} = a^{x+y}[/tex]
When dividing two numbers (or variables) of the same exponent, the solution would have the exponents subtracting each other:
[tex]a^{x} / a^{y} = a^{x-y}[/tex]
When a number with an exponent is being raised to an exponent, the solution would have the exponents multiplying each other:
[tex](a^{x)^{y} } = a^{xy}[/tex]
When there are two variables in parentheses and an exponent on the outside, the exponent will power both variables:
[tex](ab)^{x} = a^{x} b^{x}[/tex]
Answer:
Product of powers rule. ...
Quotient of powers rule. ...

Step-by-step explanation:
Answer:
4)71-x=180
x=109
5)60-x=180
x=120
Step-by-step explanation:
4) 32+72=109, 109-180=71, 71-180=109
71 is the last measure of the triangle so you just subtract that from 180.

When a volcano erupts, the height of the peak is reduced and the upper portion is removed. The height of a volcano after it erupted was 8,219.5 feet. This was 85% of the volcano's original height. What was the original height?
(answer this and show your work please thank you)
The original height was _answer this_ feet.
please help me with this thank you
Answer:
9670 feet
Step-by-step explanation:
The height given (8219.5 ft) is 85% OF ORIGINAL, hence original is much higher. But how do we figure this out?
we translate word problem to equation.
8219.5 IS 85% of TOTAL
Firstly, 85% = 85/100 = 0.85
Remember, is means =
of means multiplication
So we have:
8219.5 = 0.85 * Total
Hence, total = [let total be 7]
8219.5 = 0.85 * t
t = 8219.5/0.85 = 9670 feet

Each pair of points lies on a line with the given slope. Find y.
Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

1. How many cars per day does Car Mart sell? How did you use the table to find this rate?
2. How many cars per day does Winston's sell? Explain how you found this rate.
3. Which dealership sells more cars per day? How many more?
4. Which dealership started with more cars? How many more cars did that dealership start with?
Explain how you found your answer.
1. Car Mart sells 11 cars a day.
2. Winston's sells 10 cars per day.
3. Car Mart sells one more car per day.
4. Winston started with more cars.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Rate for Winston auto dealer is (32 - 12)/(3 - 5) = - 10.
Rate for cart mart is (32 - 43)/(3 - 2) = - 11.
Car Mart sells 11 cars a day.
Winston's sells 10 cars per day.
Car Mart sells more cars per day.
As cart mart has 43 crs left on the second day he must had 10 more cars on the starting day which is 53.
As Winston had 32 cars on the 3rd day it must had (32 + 11 + 11 ) = 54 cars on the started day so Winston started with more cars.
