Answer:
21
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
In a parellelogram opposite angles are always equal
Merry has twice as many pencils, so Sue will have half as many. Thus, S=X/2, where S is the amount of Sue's pencils.
In the same way as you could factor trinomials on the form of
<span><span><span>x2</span>+bx+c</span><span><span>x2</span>+bx+c</span></span>
You can factor polynomials on the form of
<span><span>a<span>x2</span>+bx+c</span><span>a<span>x2</span>+bx+c</span></span>
If a is positive then you just proceed in the same way as you did previously except now
<span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span><span>a<span>x2</span>+bx+c=<span>(<span>x+m</span>)</span><span>(<span>ax+n</span>)</span></span></span>
<span><span>where c=mn,ac=pq </span><span>and b=p+q=am+<span>n</span></span></span>
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value
b is the base
r is the rate
b=1+r
In this problem we have
a=4 ----> initial value (y-intercept)
b=1/2
so
1+r=1/2
r=1/2-1=-1/2
r=-0.5=-50% ----> is negative because is a decrease rate
using a graphing tool
