A. add 2
B. add 10
C. subtract 7
D. divide by 2
PLEASE HELP I WILL MARK YOU BRAINLIEST!
answer:
a.add 2
Step-by-step explanation:
A function rule describes how to convert an input value (x) into an output value (y) for a given function. An example of a function rule is f(x) = x^2 + 3. A function table is another name for an input-output table, a table that shows how a value changes according to a rule.

y = 2x - 8
x-y=3
What is X and Y
Answer:
x = 5
y = 2
Step-by-step explanation:
In this question, you will have to use one of the equations to find the value of x in terms of y and substitute it in the other equation or vice versa.
y = 2x - 8
x - y = 3
Use the second equation to find the value of x in terms of y.
x - y = 3
x = y + 3
Now that we found that, we can substitute it in the other equation.
y = 2 (y + 3) - 8
y = 2y + 6 -8
y = 2y -2
y + 2 = 2y
y = 2
Now that we got y we can substitute the value in any of the equations to find x.
x - 2 = 3
x = 5
m over 4=8 the answer is 32 what are the steps to this equation?
Explanation:
4x+8=32
Isolate for x. Start by subtracting 8 from both sides of the equation.
4x+8−8=32−8
4x=24
Divide both sides of the equation by 4.
4x4=244
x=6
A chef uses 1/2 cup of tomatoes for every 1/8 cup of onions to make salsa. How many cups of onions will the chef need for 1 cup of tomatoes? Enter the answer as a decimal.
Answer:

In a drill, Mark gives Fred a 45 meter head start. After t seconds, Fred is a distance 5t +45 from the starting line andMark is a distance of 6t from the starting line. How far ahead of Mark is Fred after t seconds?
Answer: After t seconds, Fred is far away from Mark by (45-t).
Step-by-step explanation:
Given: Mark gives Fred a 45meter head start.
After t seconds, the distance of Fred from the starting point = 5t+45
The distance of Mark from the starting point = 6t
Now, Distance between Fred and Mark after t seconds = Location of Fred - Location of Mark
= (5t+45)-6t
= 5t+45-6t
= 45-t
Hence, After t seconds, Fred is far away from Mark by (45-t).

What is the mean of the data set (0,0,0,5,6,7,10)
Answer:
4
0+0+0+5+6=7+10 = 28
28 divided by 7 is 4
To find mean you need to add up all the numbers then divided them by the total number of numbers there are. 0+0+0+5+6=7+10 has 7 numbers so I divided 28 by 7.

Answer:
volume = Pi(2x^2+3x-5) x (2x+5)^2 or P1(8x^4+52x^3+100x^2-125)
Step-by-step explanation:
radius = (4x+10)/2 = 2x+5
volume = Pi(2x^2+3x-5) x (2x+5)^2
volume = Pi(2x^2+3x-5) x (4x^2+20x+25)
volume = P1(8x^4+52x^3+100x^2-125)

a farmer was on his tractor and drove by some chickens and pigs in his field he counted 30 heads and 84 legs
*REUPLOAD* PLEASE ANSWER W EXPLANATION
Answer:
There are 18 pigs and 12 chickens.
Step-by-step explanation:
p = # of pigs
c = # of chickens
I'm assuming each animal has one head and all the pigs have 4 legs and all the chickens have 2 legs, therefore:
p+c = 30
4p+2c = 84
Elimination:
-2(p+c = 30) -2p -2c = -60
4p +2c = 84 4p +2c = 84
2p = 24
p = 12
Now substitute p for 12:
12 + c = 30
c = 18
Check:
4(12) + 2(18) = 84
48 + 36 = 84
84 = 84
There are 18 chickens and 12 pigs.
