The answer is the fourth one.
y has a line under meaning it has to be a shaded line.
x doesn’t have a line under meaning it had to be a dotted line.
the number of x is -3
so 2 and 3 can’t be the answer
y hits -2 and choice 1 is +1
if you solve for y in the 4th option it would be y > -4/5x - 2
so 4 is the correct choice

Answer:

The last option

Step-by-step explanation:

You can easily eliminate option 1 and 2 since -1 or 1 is not the y-intercept of the bold line.

You can eliminate the third option since a dotted line does not represent a "equal to"

Option 4: 5y > -4x - 10 is y > -4/5x - 2

Multiply and simplify. (12 2/3)(3 1/4)<br><br> A) 36 1/12<br> B) 36 1/6<br> C) 41 1/12<br> D) 41 1/6
Tanya [424]

Answer:

41 1/6 is the answer lets do it step by step

Step-by-step explanation:

You are usually taught to multiply the improper fractions and simplify the result.

.. (38/3)*(13/4) = (38/4)*(13/3)

.. = (19/2)*(13/3)

.. = (19*13)/6

.. = 247/6

.. = 41 1/6

You can also multiply the parts.

.. (12 2/3)*(3 1/4) = 12*3 + 12*(1/4) +(2/3)*3 +(2/3)*(1/4)

.. = 36 +3 +2 +1/6

.. = 41 1/6

hope this helps:D

If the mean of A and B is 20, the mean of B and C is 24 and the mean of A,B and C is 18.What is the mean of A and C?
Zielflug [23.3K]

Answer:

the mean of A and C is 10

Step-by-step explanation:

Given;

mean of A and B = 20

mean of B and C = 24

mean of A, B and C = 18

\frac{A + B}{2} = 20\\\\A+ B = 40 ---- (1)\\\\\frac{B + C}{2} = 24\\\\B+ C = 48----(2)\\\\\frac{A+ B+ C}{3} = 18\\\\A+ B+ C= 54---(3)\\\\From (1); \ A = 40 - B\\\\From(2); \ C = 48 - B\\\\\Substitute \ the \ values \ of \ A \ and \ C \ into \ (3)\\\\(40-B) + B + (48-B) = 54\\\\simplify;\\\\(40 + 48) + (B-B-B)= 54\\\\88 -B = 54\\\\-B = 54-88\\\\-B = -34\\\\B = 34

Recall; A = 40 - B

           A = 40 - 34

           A = 6

Also, C = 48 - B

        C = 48 - 34

       C = 14

Therefore, the mean of A and C is calculated as;

= \frac{A + C}{2} \\\\= \frac{6 + 14}{2} \\\\= 10
