Answer:
im sorry i need my points back
Step-by-step explanation:
2 (3a + 4)
first use the distributive property
6a + 8
then divide by 6 to get a by itself
6a/6 + 8/6
a = 1 1/3
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
To calculate m use the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (2,2) and (x₂, y₂ ) = (8, 5) ← 2 points on the line
m =
=
= 
the line crosses the y-axis at (0, 1) ⇒ c = 1
y =
x + 1 ← equation in slope- intercept form

For No Solution
x = 27/5
For one solution
x = 5/7
For Infinitely many solutions

First, you have to set a system of equations to determine the number of fiction and of nonfiction books.Call f the number of fiction books and n the number of nonfiction books. Then 400 = f + n. And f = n + 40 => n = f - 40 => 400 = f + f - 40 => 400 - 40 = 2f => f = 360 / 2 = 180. Now to find the probability of picking two fiction books, take into account the the Audrey will pick from 180 fiction books out of 400, and Ryan will pick from 179 fiction books out of 399, so the probability will be<span> (180/ 400) * (179/399) = 0.20 (rounded to two decimals). Answer: 0.20</span>
