Simplify the expression 5 + 2 ⋅ {(2 + 5) ⋅ 5 + 5] <br><br> 1: 55 <br> 2: 85<br> 3: 105 <br> 4: 115
FromTheMoon [43]

Answer:

85

Step-by-step explanation:

Order of operations rules (PEMDAS) govern here.  Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.

Add 2+5 first:    5 + 2*{(7)*5 + 5}

Perform the work shown inside the brackets {  and  }:  5 + 2*{40}

Perform the indicated mult.:  5 + 80

Finally, add:  85

Lera25 [3.4K]

The answer is -37.

So, let's break this down:

(7 - 10 = -3)

[45 ÷ 3 = 15]

[15 x -3 = -45]

4 x 2 = 8

8 + -45 = -37

Hoped this helped :)

Write the equation of a line that is perpendicular to y =3x-2 and that passes through the point(-9,5)
Oduvanchick [21]

Answer:

y = -1/3x + 8

Step-by-step explanation:

If two lines are perpendicular, the signs of the slope must be opposite and the slopes are reciprocals.

(basically if one is say -2/3, the other is 3/2. just flip it upside down)

So this slope is 3, so the new slope should be -1/3

The equation is now y = -1/3x + b

To find b, substitute (-9,5) in the equation

y = -1/3x + b

5 = -1/3(9) + b

5 = -3 + b

8 = b

So the equation is y = -1/3x + b
