The easiest way to remember this is to do pmbas .
P stands for parenthesis
M stands for multiplication
D stands for division
A stands for addition
S stands for subtraction
you start at parenthesis then you look for division or multiplication after you solve those you do either addition or subtraction finally you find your answer
4)C
5)A
6)D
7)-4/3x-1(use formula y=mx+b, m is slope, x and y is the x and y of the one point that is given, b is y-intercept)
8)B
***Slope is the number multiplied with the x and y-intercept is the last number. It's obvious
The probability of being in the smaller triangle is the area of the smaller triangle divided by the area of the larger triangle...
P(inside smaller triangle)=(2*2/2)/(6*5/2)
P(inside smaller triangle)=2/15
Answer:B
Step-by-step explanation:
Not sure for the rest but 9 and 11 should switch answers and 10 is square.
Hope this helps
