Answer:

D

Step-by-step explanation:

Given the 2 equations

2x + 3y = 11 → I(1)

y = x - 3 → (2)

Substitute y = x - 3 into (1)

2x + 3(x - 3) = 11 ← distribute parenthesis and simplify left side

2x + 3x - 9 = 11

5x - 9 = 11 ( add 9 to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

Substitute x = 4 into (2) for corresponding value of y

y = 4 - 3 = 1

Solution is (4, 1 ) → D

Debora [2.8K]

Answer:

-3

Step-by-step explanation:

GCF = greatest common factor

What is in common with 3x and 18? They are both multiples of 3.

3 times x = 3x

3 times 6 = 18

So we can add a negative sign in front of the 3

Therefore, the GCF is -3.

An egg of a certain kind of insect called a Tachinidae is 0.00002 meters long. What is this length in scientific notation?
GaryK [48]
2.0x10^-5 or 2.0E-5 —this is because as a small decimal number, you move the decimal to the right five spaces and then add a negative to the decimal to indicate that when you translate back (from scientific notation to 0.00002) you will move the decimal to the left
