A student is running a 10-kilometer race. He runs 1 kilometer every 4 minutes. Select the function that describes his distance from the finish
minutes.
O f(x)=x+4
O f(x)=- tox+4
O f(x)=-*x+10
O f(x)=-*x+10
Please Real answers only, i beg you.
Answers
f(x) = -(1/4)x+ 10
The plus 10 represents the 10km away he is at the start, and the -(1/4)x shows he is running 1/4 of a km closer to the finish every minute.

Sun and Spokes sells racing bikes for $1,800. A bicyclist purchases one of the bikes for 30% less
han the retail price. How much did the bicyclist spend on her racing bike?
Answers
Answer:
$1,260
Step-by-step explanation:
You first need to find 30% of 1,800, which is 540. And then, because it's 30$ less than retail price, you would need to subtract that from the initial price:
1,800-540 = 1,260

Which statement best explains whether △JKL is congruent to △MNP?
Answers
Answer:
D.
Step-by-step explanation:
The triangles are congruent, and the correct answer is D.
D. △JKL is congruent to △MNP because △JKL can be mapped to △MNP by a rotation of 180° about the origin followed by a translation 2 units up.
Rotation of triangle JKL by [tex]180^{o}[/tex] will result in the triangle with corresponding vertices of (2, 4), (3, 2) and (-1, 2).
so translating the resulting triangle two units up will result in the triangle with corresponding vertices (4, -2), (2, -3) and (2, 1) which is the same triangle like the given triangle MNP.
Which best explains why the figures are congruent?The figures is congruent because the 270° rotation about the origin or then the reflection over the x-axis would mapped ΔABC into ΔLMN.

3f
Step-by-step explanation:
f+f+f=3f
since every f has the same value
example
2+2+2=3(2)
6=6
Answer:
3f
Step-by-step explanation:
There are three f's added together, which makes 3f. If you had multiplied them all it would've been f^3, if you had divided f by 3 you would have f/3, and if f=1 it would've just been 3. This is why 3f is the best answer here.

325.623 rounded to nearest hundredth
Answers
Answer:
325.62
Step-by-step explanation:
Find the number in the hundredth place 2 and look one place to the right for the rounding digit 3. Round up if this number is greater than or equal to 5 and round down if it is less than 5 .
When your rounding you look at the number next to the number your rounding to. For example: 325.623 the hundredths place is the 2 so the number next to it is 3.
When your rounding there is a saying ( there r different ways of saying it this is the way I was taught) 5 or more raise the score. 4 or less let it rest. Meaning if it’s 5 or more raise the number one level up ( 5 goes to 6, 6 goes to 7, 7 goes to 8, 9 goes to 10). If it’s 4 or less take away the numbers behind the number your rounding to. ( Example: 45.6478 if we r rounding to the nearest tenth we look at the 4 it’s 4 or less so it would be 45.6).
So 3 is less than 4 so we take away the numbers behind the 2 therefore we get or answer 325.62

9x + 4y = 8
Answers
Answer:
slope= - 9/4 yintercept 0,2
Step-by-step explanation:
Answer:
slope = - [tex]\frac{9}{4}[/tex] , y- intercept = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
9x + 4y = 8 ( subtract 9x from both sides )
4y = - 9x + 8 ( divide terms by 4 )
y = - [tex]\frac{9}{4}[/tex] x + 2 ← in slope- intercept form
with slope m = - [tex]\frac{9}{4}[/tex] and y- intercept c = 2

What is the input when f(x)=18?
Answers
Answer: The input is 5.
Step-by-step explanation: Since both are functions of f(x), you can set 9x-27 equal to 18 and then solve the equation. 9x-27=18, add 27 to both sides to get 9x=45, divide both sides by 9, x=5.
:)
You replace the f(x) with 18 which makes it into (18)=9x-27 then you do basic algebra from there.
