Cancel out the denominators.
(x+5)² + 18 = -30
(x+5)² = -30 - 18
(x+5)² = -48
The equation is impossible, we have a negative number.
There isn't a number that squared gives a negative number (the square is always positive).
√(x+5)² = +/- √-48
x+5 = +/- √-48
IMPOSSIBLE
You can write the result in imaginary numbers
x+5=+/- 4i√3
Let's say that x represents hours that Elizabeth volunteers over 1 week. Katie volunteers x+3 and Siobhan x-1 hours per week. The equation that arises from condition in text is:
3*(x+3) = 3*(x + x-1)
x+3 = 2*x - 1
2*x - x= 3+1
x=4.
Elizabeth volunteers 7 hours
Katie volunteers 4 hours
Siobhan volunteers 3 hours
Answer:
<h2>The Answer would be (0.25, -0.25)</h2>
Step-by-step explanation:
Since you started at the origin of the plane, it would be obvious that your place would be 0.25 on the x-axis. The template for this would be (x,y) x- right and left. y- up and down. On the y-axis, the bug moved 0.25 DOWN to point A. That would be a negative since on the y-axis, it counts up to positives and down to negative. Similar to the x-axis, it counts right to positives, left to negatives. Hope this helped!
Answer:
B $10.45
Step-by-step explanation:
Fist you find how much the 2 boxes of cracker cost
$3.50 * 2 = $7
Then subtract the amount of 2 crackers by the $0.80 coupon
$7 - $0.80 = $6.20
Then add that amount to the cost of a jar of peanut butter
$6.20 + $4.85 = $11.05
Then add that about for with the amount of a package of juice boxes
$11.05 + $2.40 = $13.45
Then subtract the total amount to the $3.00 coupon
$13.45 - $3.00 = $10.45
B $10.45 is your answer
