7 0

The general and correct rule in order of operations is PEMDAS which is parentheses, exponents, multiplication, division, addition then subtraction.

Given the expression 2 + (3 + 5)2 ÷ 4 ⋅(1/2)^4
P : 2 + (8)2 ÷ 4 ⋅(1/2)^4
E : 2 + (8)2 ÷ 4 ⋅ 0.0625
M: 2 + 16 ÷ 0.25
D: 2 + 64
A: 66
S: -

The final answer is then 66.

I want solution 1 and 2 with the steps to know the final answer

Delicious77 [7]

Question 1:

Slope = 1/5

y = mx + c
y = 1/5 x + c
at point (5, -1)
-1 = 1/5 (5) + c
- 1= 1 + c
c = - 2

y = 1/5x - 2
5y = x - 10

Question 2:
slope = (9-5)/(3-1)
Slope = 2

y = mx + c
y = 2x + c

at point (1, 5)
5 = 2(1) + c
c = 5 - 2
c = 3

y = 2x + 3

Gre4nikov [31]

Given:

Guests at an amusement park must be at least 54 inches tall to be able to ride the roller coaster.

To find:

The graph that represents the set of heights that satisfy this requirement.

Solution:

Let x be the height required for the ride.

Guests must be at least 54 inches tall to be able to ride the roller coaster. It means required height is greater than or equal to 54.

$x\geq 54$

So, 54 and all values above 54 are in the solution set.

Since, 54 is included in the solution set, therefore there is a closed circle at 54. All values above 54 are in the solution set, so everything to the right of the circle is shaded.

Therefore, the correct option is C.
