Answer:
-9, 15
Step-by-step explanation:
Subtract 7 and multiply by 4
1/4 |2x-6| +7 = 13
1/4 |2x -6| = 6
|2x -6| = 24
2x -6 = ± 24
2x = 6 ±24
x = 3 ±12
x = -9, 15
_____
For graphing purposes, it is often convenient to rewrite the equation so the solutions are where the function is zero. Here, we can do that by subtracting 13 from the equation.
(1/4 |2x -6| +7) -13 = 0
Answer:
12 roses
Step-by-step explanation:
$52 to spend at the florist
a vase for $11.75
roses for $3.50 each
Calculating how much left after buying the vase:
$52 - $11.75 = $40.25
To Know the possible numbers of roses Erin can buy, divide:
$40.25 ÷$3.50 = 11,75, roundind 12 roses
Answers:
=====================================================
Explanation:
By definition, 
Squaring both sides gets us 
Then multiply both sides by i to get 
Repeat the last step and you should get 
---------------
Notice we have this pattern going on:
Once we reach i^4, we start the process over again.
It repeats every 4 terms.
This means we'll divide the exponent over 4 and look at the remainder. We ignore the quotient completely.
157/4 = 39 remainder 1
That remainder 1 is the exponent of the simplified term
---------------
Similarly,
315/4 = 78 remainder 3
So 
---------------
102/4 = 25 remainder 2
----------------
76/4 = 19 remainder 0
Answer:
C.) f(x) = −4x + 200
Step-by-step explanation:
Since the number is decreasing, you know the slope will be negative, eliminating the first two choices. The equation in the last choice does not match the given data, so it can be eliminated.
In other words, the easiest way to solve this problem is to check the answers against the given data.
_____
If you want to write the equation from scratch, you need to find the slope. That is ...
(change in number of cars)/(change in weeks) = (184 -192)/(4 -2) = -8/2 = -4
This matches only one answer, but you can go on to finish the equation by starting with point-slope form:
y -192 = -4(x -2)
y = -4x +8 +192 . . . . add 192, eliminate parentheses
y = -4x + 200 . . . . matches choice C.)
Yes,the answer is 0. hope it helps
