The function f(x) = -x + 5 has domain values of -3, 3, and 9.
Which are the corresponding range values?
A 3,7, and 11
B 7,3, and -1
C 9,3, and -3
D 12,3, and -6
help!
Answer:
A 3,7, and 11
Step-by-step explanation:
Answer:
A 3,7, and 11
Step-by-step explanation:
Domain is the x-value so you replace all the x's in f(x)=-x+5 with -3,3, and 9
f(-3)=2/3(-3)+5
= 3
f(3)=2/3(3)+5
=7
f(9)=2/3(9)+5
=11
Hope this helps!
How do you find the unit rate?
Answer:
A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

Serena paid $194.99 for a game system and then bought two equally-priced games. She spent a total of $284.97.
Part A
If p represents the price of one game, which equation represents the situation?
2p – 284.97 = 194.99
2p + 194.99 = 284.97
2p + 284.97 = 194.99
2p – 194.99 = 284.97
Part B
What is the price, p, of one game?
$ ____________
Answer:
Part A is 2p – 194.99 = 284.97
Step-by-step explanation:
the price for one game is 44.99

Answer:
B. 21 and 19/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
21.76=21.761
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
21.761×100100=2176100
Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,
2176÷4100÷4=54425
Simplify the improper fraction,
=211925
In conclusion,
21.76=211925

Which of the following is a pair of similar triangles?
A) Image A (1st Image)
B) Image B (2nd Image)
C) Image C (3rd Image)
D) Image D (4th Image)
Image C for sure.
Sure, both triangles don't show all angles, But if you look at the first triangle in image C, it's just a more stretched out version of the second one. The angles are the same, just one triangle is slightly taller.

A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.
Answer:
29.88 inches
Step-by-step explanation:
Equation of a line is given in the form
Where
m is the slope [rate of change, here, rate of decrease]
c is the y-intercept [at 1920, the snowfall]
From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24
Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:
y = mx + b
y = -0.24 x +48.6
To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:
y = -0.24(78) + 48.6 = 29.88 inches
Answer:
29.88 inches

5 ( f + 4) = 4 ( f - 6)
f = -44
Hope this helps :)
Answer:
The answer is -44
Step-by-step explanation:
First, you use distributive property on each side.
5xf + 5x4 = 4xf-4x6
5f+20=4f-24
Then you subttract 5f to both sides of the equation.
5f+20=4f-24
-5f -5f
20=-1f-24
Next, you add 24 to both sides of the equation.
20=-1f-24
+24 +24
44=-1f
Finally, you divide -1f from each side of the equation.
44=-1f
/-1f /-1f
Your final answer should be -44=f
or f = -44
