Simplify the expressions #3
a) 6+2y-3+4y
=3+6y
b)16+t-2s+12
=18+t-2s
c)3w-6v+4v-100
=3w-2v-100
d)79t+50-30t-3
=49t+47
all i can do for now
Answer:
The zeros of the function are x=-7 and x=2
Step-by-step explanation:
we have
we know that
The zeros or roots of the function are the values of x when the value of the function is equal to zero (also is called the x-intercepts)
so
For A(x)=0
Remember that
The <u><em>Zero Product Property</em></u> states that
if ab = 0, then either a = 0 or b = 0, or both a and b are 0
so
Let
---->
---->
therefore
The zeros of the function are x=-7 and x=2
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).
Answer:
see below
Step-by-step explanation:
a) 2(x - 1) = 4 (x + 2)
Distribute
2x-2 = 4x+8
Subtract 2x from each side
2x-2x-2 = 4x-2x +8
-2 = 2x+8
Subtract 8 from each side
-2-8 = 2x+8-8
-10=2x
Divide each side by 2
-10/2 = 2x/2
-5 =x
b)(3 - x) (x + 2) = 0
We can use the zero product property
3-x = 0 x+2= 0
3-x+x=0+x x+2-2=0-2
3=x x=-2
Answer:
dist = 60 mph * (3.5 hrs) = 210 miles
The answer is 210 Miles
