7. 21.39
8. 6
those are the only two i know
Answer:
9
Step-by-step explanation:
Good ol' PEMDAS
First things first, we simplify what is in the parentheses.
4/2 ÷ 2 + (3² - 1)
4/2 ÷ 2 + (9 - 1)
4/2 ÷ 2 + 8
Next we do division. Because there are two instances of division, we work left-to-right. Note that a fraction such as 4/2 is division itself.
4/2 ÷ 2 + 8
2 ÷ 2 + 8
1 + 8
Lastly, it just solving the addition.
1 + 8 = 9
Answer:
(s-6)/r
option D
Step-by-step explanation:
The slope-intercept form a line is y=mx+b where m is the slope and b is the y-intercept.
Compare y=mx+b and y=cx+6, we see that m=c and c is the slope.
Now we are also given that (r,s) is on our line which means s=c(r)+6.
We need to solve this for c to put c in terms of r and s as desired.
s=cr+6
Subtract 6 on both sides:
s-6=cr
Divide both sides by r:
(s-6)/r=c
The slope in terms of r and s is:
(s-6)/r.
Answer:
a)
side a is opposite, side b is adjacent, side c is hypotenuse
b)
side a is adjacent, side b is opposite, side c is hypotenuse
