Answer: B (The cost of a notebook is $0.75, and the cost of a folder is $0.25.)
Step-by-step explanation:
No need for explanation. i know i’m right!!
-4<em>n</em> ≥ 12 ==> <em>n</em> ≤ -3
<em>n</em> + 5 > 2 ==> <em>n</em> > -3
But <em>n</em> cannot be both less than/equal to -3 AND greater than -3, so there are no integers <em>n</em> that satisfy these inequalities.
Answer:
200
Step-by-step explanation:
Steps
6.6 x 10^{-2}/3.3 x 10-4
10^{-2}-4(-4) x 6.6/3.3
10^{-2} x 6.6 = 660/3.3
=200
<span>In this item, it is unclear of the weights of each of the
t-shirt and sweatshirt. We first represent the weights of the t-shirts and the
sweatshirts by t and s, respectively. If for example, each t-shirt weighs 2
pounds and each sweatshirt weighs 3 pounds, the answer would be the first
choice. </span>
f(x) = 2(x^2 + 14x + ) - 5 2 is taken out of first 2 terms.
f(x) = 2(x^2 + 14x + (14/2)^2 ) - 5 - 2(14/2)^2
<em><u>2 steps </u></em>
- Inside the brackets: Linear term's coefficient (14) divided by 2 and squared
- Outside the brackets: (14/2)^2 multiplied by 2 and subtract so that there is no change in the value of the quadratic.
f(x) = 2*(x + 7)^2 - 103
The graph is of the original quadratic.
