Mathematics
1 answer:
FromTheMoon [43]3 years ago
3 0

Answer:

a)2x-3y

b)4(9a-4)

Step-by-step explanation:

<h3>a)</h3>

we want to expand the following expression:

\displaystyle -   \frac{1}{4} ( - 8x + 12y)

well to do so we consider distributive property thus distribute:

\displaystyle -   \frac{1}{4} (- 8x )+  -  \frac{1}{4}( 12y)

reduce fraction which yields:

\displaystyle -   \frac{1}{4} (- 8x )+  -  \frac{1}{4}( 12y) \\  \\  \displaystyle 2x + ( - 3y)

simplify Parentheses:

\displaystyle \boxed{ 2x - 3y}

<h3>b)</h3>

in the expression there's a common factor of 4 therefore factor it out:

\displaystyle 9.4a - 4.4 \\  \\  \displaystyle   \boxed{4(9a - 4)}

(a)
the list would be
-20, -12, -8, -1, 1, 5, 10
the other intergers would have to be greater than 1 in order to be on the correct side and cause 1 to be in the middle. They could be anything but 5 and 10 because these were already chosen.

(b)
the list would be like before
-3 was not included so one of the chosen would be -3 and the other would have to be less than -3 but not -8, -12, or -20 beacuse those were already chosen

How can I graph 34+12d&gt;100 on a number line?
marissa [1.9K]

Answer:

d> 5.5

The graph in the attached figure

Step-by-step explanation:

we have      

34+12d>100

Solve the inequality for d

That means ---> isolate the variable d

Subtract 34 both sides

12d>100-34\\12d> 66

Divide by 12 both sides

d>\frac{66}{12} \\d>5.5

The solution is the interval (5.5,∞)

All real numbers greater than 5.5

In a number line the solution is the shaded area at right of d=5.5 (open circle)

The value of d=5.5 is not included in the solution
