Answer:
y- intercept = 
Step-by-step explanation:
Given
f(x) = 
To find the y- intercept let x = 0 , then
f(0) = 
[ 
= 1 ]
= × 1 = ← y- intercept
-x² - x + 6
First thing I would do is distribute out that negative. Your new problem is:
- (x² + x - 6)
Now, factor the inside. We need to find products of - 6 that when added together have a sum of positive 1. They are 3 and - 2.
- (x² + 3x - 2x - 6)
Group together and find your factors. I'm going to short cut and go right to them for the sake of space and time.
- (x + 3)(x - 2)
Your answer is Option B
Answer:
Step-by-step explanation:
total marbles=5+8+4+3=20
when he is drawing without replacing means red marble is drawn from 20 marbles.
Blue marble is drawn from 19 marbles.
when he is drawing with replacing means he draws one red marble from 20 marbles.Then he replaces it and draws blue marble from 20 marbles also.
Answer:
True, these measures do form a right triangle.
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
(6)^2 + (8)^2 = (10)^2
36 + 64 = 100
100 = 100
So, its true these measurements do form a right triangle.
175 x .64 = 112 students planning to attend college.
