Well for starters, to negatives next to eachother make a positive. So now we rewrite the problem, -11/12 + 5/12.

Since 11/12 is bigger than 5/12, we use the bigger number’s sign which is subtraction. So 11/12 - 5/12 = 6/12.

However, you want the answer to be in simplest form. You can break down 6/12 to a smaller fraction by dividing 6 into both numbers. 6 divides by 6 is 1. And 12 divided by 6 is 2.

So your final answer is 1/2. Also known as half. I hope this helped.

What are the x and y intercepts of the graph of -4x + 5x = -40?
Nataly [62]

Hey!

Hope this helps...

~~~~~~~~~~~~~~~~~~~~~~~~~~

-4x + 5x = -40

y = -4x +5x + 40

y = x + 40

~~~~~~~~~~~~~~~~~~~~~~~~~~

by the look of it, after you turn that equation into slope-intercept form (y = mx + b) the intercepts are y = 40  &  x = -40

Graph this please due today
vaieri [72.5K]

Answer: see last picture

Step-by-step explanation:

We see that the y-intercept is 10 and the slope is -3

so when x = 0, y = 10

Graph this first point (picture 1)

Since the slope is -3, every time you go one unit to the left, you go down 3 units, so graph this second point (picture 2)

Continue this until you have no more room on the graph (picture 3)

now draw a line through the dots (picture 4)

What is the area of this?
Vanyuwa [196]

area = lw \\ area = (7.5)(6) \\ area = 45 {feet}^{2}

area =  \frac{1}{2} bh \\ area =  \frac{1}{2} (6)(4) \\ area =  \frac{1}{2} (24) \\ area = 12 {feet}^{2}

total area = 45 + 12

total area = 57 feet²
