Answer:
<h2>D. y = 8x² + 8x + 4</h2>
Step-by-step explanation:
The equation of a linear function is in form:

We have:




Answer:
50 combos
Step-by-step explanation:
Put it into an equation first in order to find x.
2x + 250 = 7x
Subtract 2x from both sides.
250 = 5x
Then divide both sides by 5.
x = 50
Therefore you need 50 combo meals in order to make the amount made equal to the amount paid.
<u>You can check your work by plugging in the number to both.</u>
$250 plus the $2 times 50 combo meals.
250 + 2(50) = 350
$7 times 50 combo meals
7 x 300 = 350
Answer: W’ (3, 0)
Explanation:
W(2,0)
2 • 1.5 = 3
0 • 1.5 = 0
W’ = (3,0)
Answer:
A is b/c the 2 minutes and 54 seconds are 174 seconds and the .29 also gets carried over, so it is 174.29. (You are converting minutes to seconds [60 seconds=1 minute])
B the average time of the four runners would be 43.5725 seconds, b/c 174.29/4=43.5725
Answer:
6 - 8x
Step-by-step explanation:
The question is:
(-3x + 4) - (5x - 2)
When you have two numbers inside a bracket, it is called a binomial. (Here we have two binomials). When you subtract a binomial, you "add the opposite".
To get rid of the second pair of brackets, <u>add the opposite of 5x</u>. Since 5x is positive, add negative 5x.
(-3x + 4) - (5x - 2)
= (-3x + 4) +-5x -(- 2) A positive and a negative make a negative
= (-3x + 4) - 5x -(- 2)
Add the opposite of -2. The opposite of -2 is positive 2.
= (-3x + 4) - 5x -(- 2)
= (-3x + 4) - 5x ++ 2 Two positives make a positive
= (-3x + 4) - 5x + 2
Now you can remove all brackets.
= -3x + 4 - 5x + 2 Collect like terms
= 4 + 2 - 3x - 5x Rearranged so you can see like terms
= 6 - 8x Final answer
