Since all the terms have the same base you just deal with the exponents.
(X^2)(x^7)=x^9
X^9(x^-3)=x^9/x^3=x^6
Answer:
y=3x+2
Step-by-step explanation:
y=mx +b, m is slop, slop is given and = 3--->
y=3x+b, lets find b
substitute x and y coordinates of given point into y=3x+b---->
2=3 x 0 + b ; solve for b
b=2----->
y= mx+b is y=3x+2
Answer:
8, 9 and 10
Step-by-step explanation:
We would have to find the 3 consecutive integers.
Consecutive integers are one after another, such as:
1, 2, 3, ... etc.
So, if we let the first integer be "x", the next one is 1 unit apart, so next one would be:
x + 1
Next one:
x + 2
So, we have 3 consecutive integers:
x, x + 1, x + 2
It is given, <em>3 times smallest (x) is 14 MORE THAN largest (x + 2)</em>. So we can write:
3x = x + 2 + 14
Now we solve for x:

So, the integers are:
8, 9 and 10
Answer:
option c
amplitude 1 ; period 2π/3
Step-by-step explanation:
Given in the question a function,
f(t)=-cos3t
Standard form of cosine function is
f(t)=acos(bt)
Amplitude is given by = |a|
Period of function is given by = 2π/b
So the amplitude is |-1| = 1
the period is 2π/3 = 2π/3
The answer is 32% good luck
