All integers are whole numbers is false Whole numbers are non-negative while integers are negative, positive or zeros. D
Answer:
Step-by-step explanation:
<h3>The first line</h3>
- Line x - y > 5 ⇒ y < x - 5
<u>This line has positive slope and the y-intercept is -5, shaded area is below the line, covers the areas:</u>
<h3>The second line</h3>
- Line x + 2y < -6 ⇒ 2y < - x - 6 ⇒ y < -1/2x - 3
<u>This line has negative slope and the y-intercept is -3, shaded are is below the line, covers the areas:</u>
<u>Solution of the system is the intersection of the areas:</u>
check your calculator for the [!] factorial button.
also bear in mind that most calculators also have an [ₙPᵣ] button, to get Permuations, and you can just use that.
the discriminant b^2 - 4ac when the equation is in the form of ax^2 +bx+c=0
13x^2-16x = x^2 -x
we need to get in it the standard form
subtract x^2 from each side
12x^2 -16x = -x
add x to each side
12x^2 -15x = 0
12x^2 -15x -0 =0
a=12 b=-15 c=0
b^2 -4ac
the discriminant = b^2
b^2 = (-15)2 = 225
Answer: 7 months
Step-by-step explanation:
He started at 4 pounds so if he grew 3 pounds every month, it would take 7 months to grow 21 pounds. 21 pounds plus 4 pounds is 25 pounds.
