Answer:
8
Step-by-step explanation:
f (x) = 7 (x-1) +8
For f(1) we plug 1 into x.
f(1) = 7 (1-1) +8
Simplify
f(1) = 8
To simplify x^2-3 =5x
You would first subtract 5x from both sides
X^3-5x-3
Next you would plug this into the quadratic equation:
X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)
Then simplify,
5+/- the squareroot of 24 + 12 / 2
5+/- The squareroot of 36 /2
5+/- 6 / 2
Then solve if it’s an addition or subtract
5+6/2
X=11/2 or 5 1/2
5-6/2
X= -1/2
The answer is x=-1/2 or x=11/2
Hope this helps
4x^2-3x and I have to have 20 characters
Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000368
mm, while the length of the second strain measures 0.000000064 mm. How much larger is the first strain than the second?
We can figure this out using scientific notation.


Put 3.04e-7 in standard notation.

Put 0.00000304 back into scientific notation, instead with a multiply sign.
Move the dot back, making the number in between 1-10.
In this case, we would move it back 7 times.
