Ierofanga [76]

Answer:

$3185

Step-by-step explanation:

Multiply the number of grade 6 students by the money needed ($3.50) and you get 318x3.50=1113

Multiply the number of grade 7 students by the money needed ($3.50) and you get  286x3.50=1001

Multiply the number of grade 8 students by the money needed ($3.50) and you get 306x3.50=1071

Add all the total amounts together and you get $3185

Match each exponential function to its percent rate of change.
vredina [299]
This question is about exponent function. All the function in this question is following a pattern of f(x)= a(b)^{x}In this function, a is the initial/starting quantity and b is the base of the exponent. The option in this problem is about growth/decay that was determined by the base of the exponent. So, to answer this question you just need to pay attention to the variable b

1. Answer: 4% grow 
f(x)= a(b)^{x}
f(x)= 46(1.04)²
Then the value of the variable would be:
a= 46
b=1.04
Since b is >1 then it is a growing function. The grow in percent would be: (1.04 * 100%) - 100%= 104%-100%=4%

2. Answer: 4% decay 
f(x)= a(b)^{x}
f(x)= 104(0.96)²
Then the value of the variable would be:
a= 104
b=0.96
Since b is <1 then the function would decay. The rate of change percent would be: (.96 * 100%) - 100%= 96%-100%= -4%. The function rate of change is 4% decay 

3. Answer: 40% decay 
f(x)= a(b)^{x}
f(x)= 74(0.6)²
Then the value of the variable would be:
a= 74
b=0.60
Since b is <1 then the function would decay. The rate of change percent would be: (0.60 * 100%) - 100%= 60%-100%= -40%. The function rate of change is  40% decay

4. Answer: growth 40%
f(x)= a(b)^{x}
f(x)= 44(1.4)²
Then the value of the variable would be:
a= 44
b=1.4
Since b is >1 then the function would grow. The rate of change percent would be: (1.40 * 100%) - 100%= 140%-100%= 40%. The function rate of change is 40% growth

5. Answer: 14% decay
f(x)= a(b)^{x}
f(x)= 40(0.86)²
Then the value of the variable would be:
a= 40
b=0.86
Since b is <1 then the function would decay. The rate of change percent would be: (0.86 * 100%) - 100%= 86%-100%= -14%. The function rate of change is 14% decay

6. Answer: 14% growth
f(x)= a(b)^{x}
f(x)= 8(1.14)²
Then the value of the variable would be:
a= 8
b=1.14
Since b is >1 then the function would grow. The rate of change percent would be: (1.14 * 100%) - 100%= 114%-100%= 14%. The function rate of change is 14% growth

Select the number that matches this list of factors:
IrinaK [193]

Answer:

12

Step-by-step explanation:

11 doesn't go into any numbers because it is prime, same with 17. 15 only goes into 3 and 5 so that's not it either. 21 only goes into 3 and 7, 26 doesn't go into 4 nor 6. 4 doesn't go into 30 evenly, so that leave just 10 and 12. 3,4,nor 6, go into 10. That leaves only 12 as the final answer.

Which ordered pair is in the solution set of 6x + 4y ≤ −2?
Nutka1998 [239]

Answer:

x≤ −2/3y + −1/3

Step-by-step explanation:

because...

Step 1: Add -4y to both sides.

6x + 4y + −4y ≤ −2+−4y

6x ≤ −4y −2

Step 2: Divide both sides by 6.

6x/6 ≤ \frac{-4y-2}{6}

x ≤ −2/3y + −1/3

Therefor, the answer is x≤ −2/3y + −1/3

* Hopefully this helps:) Mark me the brainliest:)!!
