Answer:
1
Step-by-step explanation
Since you are given two points you can calculate the slope by use the formula Y1-Y2/X1-X2.
In this case:
Y1 = 5
Y2 = 7
X1 = 7
X2 = 9
(5-7)/(7-9) = -2/-2 = 1
All you have to do is combine the like terms and the answer is 6x^4-x^3-5x^2+10x+5
Answer
The statment true about the image be
The measure of ∠TRU is 72° .
Reason
As shown in the image
∠QRU = 90°
∠ TRQ = 18°
Now ∠QRU be written as the sum of the ∠ TRQ and ∠TRU .
Thus it becomes
∠QRU = ∠ TRQ + ∠TRU
put the value ∠QRU and ∠ TRQ
we get
90° = 18 ° + ∠TRU
Solving the above
∠TRU = 90° - 18°
∠TRU = 72 °
Therefore the measure of ∠TRU is 72 °.
Hence proved
ANSWER
The restrictions are

EXPLANATION
We were given the rational function,

The function is defined for all values of a, except

This has become a quadratic trinomial, so we need to split the middle term.
We do that by multiplying the coefficient of
which is 5 by the constant term which is 3. This gives us 15.
The factors of 15 that adds up to 16 are 1 and 15.
We use these factors to split the middle term.

We now factor to get,

We factor further to get,

This implies that,

This gives

These are the restrictions.
Multiply the four, canceling it out. Multiply the four with the negative nine. Divide 9 by -36 and you get x=4
