Alina [70]

Answer:

(t^2 -4) (t^2 +4)

(t-2)(t+2)(t^2+4)

Step-by-step explanation:

t^4 - 16

We can write this as the difference of squares

We know the dfference of squares is

(a^2 - b^2) = (a-b) (a+b)

( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4)

We can write t^2 -4 as the difference of squares

t^2 -4 = t^2 -2^2 = (t-2)(t+2)

Replacing this in

( t^2 ^2 - 4^2) = (t^2 -4) (t^2 +4) =  (t-2)(t+2)(t^2+4)

If logM/N=5 and logP/N=7, what can you say about the relationship between M and P?. . A. M=2P. B. P=2M. C. P=100M. D. P=10M
liubo4ka [24]
<span>log (M/N) = log M - log N
 so log M - log N = 5
log (P/N) = log P - log N
so log P - log N = 7
 If you subtract equation 2 from equation 1, you have log M - log P = -2
 That means that log (M/P) = -2 ----> 10^-2 = M/P ---> P = 100M</span>

If f(x)= 3x-1/4x+2 find f(x-1/ x+2)
Basile [38]

Answer:

The value of this new equation would be (2x - 5)/6x.

Step-by-step explanation:

In order to find the value of this equation, we need to take the original equation and replace every x with (x - 1/x+2).

f(x)= 3x - 1/4x + 2

f(x)= [3(x - 1/x+2) - 1]/[4(x - 1/x+2) + 2]

f(x) = [(3x - 3/x + 2) - (x + 2/x + 2)]/[(4x - 4/x + 2) + (2x + 4/x + 2)]

f(x) = (2x - 5/x+2)/(6x/x + 2)

f(x) = (2x - 5)/6x

Find the x and y intercepts of the linear equation 2x - 4y = -20
dsp73

Answer:

see explanation↓

Step-by-step explanation:

We are given the following equation of a line:

2x-4y=-20

To determine the x-intercept we must set "y = 0":

2x-4(0)=-20

2x=-20

Now, we divide both sides by 2:

x=-\frac{20}{2}=-10

Therefore, the "x" intercept is -10.

To determine the y-intercept we set "x = 0":

2(0)-4y=-20

-4y=-20

Now, we divide both sides by -4:

y=\frac{-20}{-4}=5

Therefore the y-intercept is 5.
