Answer:

1

Step-by-step explanation:

(−4)−(−2)–{(−5)–[(−7)+(−3)–(−8)]}

PEMDAS

Work from the inside out

Change subtracting negatives to adding

(−4)+2–{(−5)–[(−7)+(−3)+8)]}

(−4)+2–{(−5)–[(-2)]}

(−4)+2–{-5+2}

(−4)+2–(−3)

Changing to adding

(−4)+2+3

-2+3

Answer:

1

Step-by-step explanation:

= (- 4) + 2 - {(- 5) - [(- 7) + (- 3) + 8)]

= (- 4) + 2 - {(- 5) - [(- 2)]}

= (- 4) + 2- {- 5 + 2}

= (- 4) + 2 - (- 3)

= (- 4) + (2 + 3)     (2 negatives make a positve)

= (- 4) + 5

= - 4 + 5

= 1

Hope this helps, and please mark me brainliest if it does!

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. 568 fee
amm1812
<span>First, we write an equation to represent that the fencing lengths add up to 568 feet. we call the side of the fence that has three segments of its length x and the side with only two segments y. We write 3x + 2y = 568. We also know that the area of the rectangle is equal to xy, so area = xy. We put y in terms of x using our first equation and find that y = (568 - 3x)/2. We plug this into our area equation and find that area = (568x - 3x^2)/2. To find the maximum we set the derivative equal to 0 and end up with 0 = 284 - 3x. We solve for x and get 94 and 2/3. We then put that into our first equation to find y = 142. So the dimensions that maximize the area are 94 2/3 x 142.</span>

Solve the system of equations given below.
eduard

Answer:

The system of this equation is ( -1, 10) which is Option A.

Step-by-step explanation:

Solve for y in the first equation.

y =  - 5x + 5 \\  - 2y =  - x - 21

Replace all occurrences of yy with -5x+5 in each equation.

10x - 10 =  - x - 21 \\ y =  - 5x + 5

Solve for x in the first equation.

x =  - 1 \\ y =  - 5x + 5

Replace all occurrences of x with -1 in each equation.

y = 10 \\ x  =  - 1

The solution to the system is the complete set of ordered pairs that are valid solutions.

(−1, 10)

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>system</u><u> </u><u>of</u><u> </u><u>this</u><u> </u><u>equation</u><u> </u><u>is</u><u> </u><u>(</u><u>-1</u><u>,</u><u> </u><u>10</u><u>)</u><u>.</u><u> </u>

<u>Option</u><u> </u><u>A</u><u>.</u>
