Since it's a 25/35 for animals with beige fur, or 5/7, and a 10/35, or 2/7, probability that kittens have beige fur, there's a 7/7, or 100% chance a randomly picked animal will either have beige fur or is a kitten.
Answer:
n=6
Step-by-step explanation:
6n= 30+3(n-4)
6n=30+3n-12
6n-3n=30-12
3n=18
n=18/3
n=6
Answer:
Step-by-step explanation:
1) Use the grid method to expand the two brackets
2) Collect like terms
3) Form the statement!

There are 1,000 milligrams in 1 gram, there fore you would have to take 2 Tylenols to take 1 gram.
Remember the shortcut way for graphing quadratic equations
- A quadratic function has graph as parabola
- Hence on both sides of vertex the parabola is symmetric and axis of symmetry is vertex x values .
- y on both sides for -x and +x is same
#1
Vertex
As a is positive parabola facing upwards
Find y for same x distance from vertex
I took 3-1=2 and 3+1=4
- f(2)=2(2-3)²-1=2(-1)²-1=2-1=1
- f(4)=2(4-3)²-1=1
Now plot vertex and these two points (2,1) and (4,1) on graph then draw a parabola by freehand
#2
- y=(x-2)(x+4)
- y=x²+4x-2x-8
- y=x²+2x-8
Convert to vertex form
Vertex at (-1,-9)
Same take two equidistant x values
Let's take -1-1=-2 and -1+1 =0
- f(-2)=(-2+1)²-9=1-9=-8
- f(0)=(1)²-9=-8
Put (-1,-9),(-2,-8),(0,-8) on graph and draw a freehand parabola
#3.
Yes it can be verified by finding the coordinate theoretically on putting them on function then can be verified through putting them on graph whether they matches or not
