Answer:
PEMDAS.
parenthesis first, then exponents, next would be mutiplication/division, then lastple add/subtract.
Step-by-step explanation:
first would be 15-7, then the 3^2, etc
Answer:
it is 1/2
Step-by-step explanation:
The product of a lines slope M and the slope K of a perpendicular is -1:
M*K=-1
This implies
K=-1/M
since
M * -1/M=-1
In our example we are given a line of slope M=-2 therefore the slope K of a line to perpendicular to this line is:
M*K=-1
-2*K=-1
K=-1/-2=1/2
Answer: #1
Explanation:
Because the y int represents the starting point which in this case is -7 and the slope is -3/1 which represents the direction that the fish is swimming in (up or down)
Here, Your Expression: y = 0.25 (2^x)
So, we can see the expression is "Exponential" which increases double in every hour. So, the only graph with that pattern is 3rd one.You can compare following coordinates: (1, 50), (2, 100), (3, 200)
For every 1 value of x, y increases to it's double.
In short, Your Answer would be Option C
Hope this helps!
