Answer:
586.5 cents
Step-by-step explanation:
if one ounce costs 25.5 cents and the bag contains 23 oz, you multiple 25.5 by 23 to get 586.5
Mutiply first equation by -1 and add to 2nd
-y=3x-6
<u>y=x^2-4 +</u>
0=x^2+3x-10
factor like any equation
what 2 numbers multiply to -10 and add to 3
-2 and 5
0=(x-2)(x+5)
set to zero
x-2=0
x=2
x+5=0
x=-5
solve for y in each case
for x=2
y=2^2-4
y=4-4
y=0
(2,0) is a point
for x=-5
y=(-5)^2-4
y=25-4
y=21
(-5,21) is another
the solutions are
(2,0) and
(-5,21)
Answer:
D. 
Step-by-step explanation:
The period of the functions 
is 
The period of the function 
is ALWAYS 
In your case, you have function 
and this function has the period
You need to find the function that will have the period that is half of 
so
So, correct choice is
Answer:

Answer:
A = 735 cm²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 35 and h = 21 , then
A = 35 × 21 = 735 cm²
