Answer:
Step-by-step explanation:
x + 5/y^2
x = 2/3
y = 1/3
2/3 + 5 / (1/3)^2 Expand (1/3)^2
2/3 + 5 / (1/9) Put a 1 underneath the 5
2/3 + 5/1 / (1/9) Invert and multiply the second expression
2/3 + 5/1 * 9 Simplify 5/1
2/3 + 5* 9 Combine
45 2/3
I'm not getting any of these. It's possible I'm misreading the question, but what you've given is the result I got. All I can suggest is that you ask your teacher how this is done.
Answer:
y=1/2x+5
Step-by-step explanation:
first you have to find the slope by using
so when you plot in your points and you will get 1/2x.
then you need to find your y-intercept
and since you don't have a 0 you have to slove by using y=mx+b (slope-intercept) formula
you plug in your points and you will get
b=5 and that is how you get your equation.
Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
Answer:
hello :
-1/4y-2 1/4y+1/2(4-2y) = -1/4y-2/4y+4/2 -2/2y
= ( -1/4 -2/4 - 4/4)y +2
= (-7/4)y + 2
Answer:
2.6768·10^(-14) (Answer C)
Step-by-step explanation:
Problem 4: We ADD the powers of 10: 10^6·10^(-3) = 10^3. Also, 3.6·1.7 = 6.12. Therefore, Answer D is correct.
Problem 5: Again we ADD (combine) the powers of 10: 10^(-10)·10^(-5) =
10^(-15). 4.78·5.6 = 26.768. Our intermediary answer is thus:
26.768·10^(-15). This must be rewritten in the form x.xxxx, so here we have:
2.6768·10^(-14) (Answer C)
