The simplest form is 4y+6?
you distribute the 4 to everything in the parentheses and then combine like terms so you would combine the 8 and -2
Answer:
Statement A is true.
Step-by-step explanation:
A. If the group sells 15 prints, they will lose $85.
B. If the group sells 12 prints, they will lose $204.
C. If the group sells 35 prints, they will make $935.
D. If the group sells 28 prints, they will lose $136.
f(p) = 17p - 340
p = prints
f(p) = profit
Let's check the statements to see which one is true.
A. 17.15 - 340 = - 85 OK!
B. 17.12 - 340 = -136 (false, they will lose $136)
C. 17.35 - 340 = 255 (false, they will make $255)
D. 17.28 - 340 = 136 (false, they will make $136)
Answer:
At 43.2°.
Step-by-step explanation:
To find the angle we need to use the following equation:
Where:
d: is the separation of the grating
m: is the order of the maximum
λ: is the wavelength
θ: is the angle
At the first-order maximum (m=1) at 20.0 degrees we have:
Now, to produce a second-order maximum (m=2) the angle must be:
Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.

5 x 3²⁴ bacteria will there be after one day.
What is exponents?
Exponentiation could be a calculation, written as bⁿ, involving 2 numbers, the bottom b and also the exponent or power n, and pronounced as "b to the n".
Consider what is actually happening in the question.
You begin with 5 bacteria, and after 1 hour it has tripled so you now have
5x 3=15.
Next hour, it triples again so you now have 5 x 3 x 3=45
You can see the pattern shows that the number of bacteria is multiplying every hour by a factor of 3. An exponent denotes how many times we are multiplying a number by itself, for example: 3⁴ means we are multiplying the number 3 a total of 4 times (3 x 3 x 3 x 3).
Therefore the question is requiring us to triple the number of bacteria every hour for 24 hours, which means we are multiplying by 3 a total of 24 times. This gives us:
n x 324 where n is the number of bacteria you begin with.
Since you begin with 1 bacteria, the solution is 5 x 3²⁴.
Hence 5 x 3²⁴ bacteria will there be after one day.

|4x-9|=5x
subtract 4 to both sides
and that will give you
|-9|=x then the 9 turns positive because of the brackets
9=X
