Answer: -b - 9
Step-by-step explanation:
First, since the a cancel eachother out we are left with (4-b) + (-6-7)
Second, you want to add the -6 and -7 to get -13, so (4-b) - 13
Finally, add the 4 to the negative 13 to get (-b - 9)
Hope this helps.
If the scale factor is 1 1/2, then we can multiply x's corresponding side by 1 1/2 to get x.
The corresponding side is 2, so 2 * 1 1/2 is 3, making x = 3.
Answer:
<u>The correct answer is D. -5 +/- i√2</u>
Step-by-step explanation:
Let's solve for x, the equation given to us, this way, using the quadratic formula:
x = (- b +/- √b² - 4ac)/2a
Replacing with the real values, we have:
x = (-10 +/- √10² - 4 * 1 * 27)/2
x = (-10 +/- √100 -108)/2
x = (-10 +/- √-8)/2
x = (-10 +/- √-1 * 4 * 2)/2 Let's recall that √-1 = i
x = (-10 +/- 2i√2)/2
x = 2 (-5 +/- i√2)/2 (Dividing by 2 both the numerator and the denominator)
<u>x₁ = -5 + i√2</u>
<u>x₂ = -5 - i√2</u>
<u>The correct answer is D. -5 +/- i√2</u>
Answer: 25 bags of chips and 25 soda
Step-by-step explanation:
The amount I have with me is $100.
Since bags of chips cost $3 each and Soda costs $1 each. Both will cost total of $4 each.
In order to know the amount I can buy with $100 that is with me, I will have to divide $100 by $4 which gives $25.
This shows I can get 25 bags of soda @$25 at the rate of $1 each and have a balance of $75 which is enough to buy 25bags of chips @$3 each.
La primera es 264.6
La segunda es 125
Si no me equivocó
