Answer:
okay so, you can only carry out two operations at a time: so here goes
Step-by-step explanation:
6.2*10^17 + 1.2 x 10 ^15
on your calculator: 6.2 exp 17 + 1.2 exp 15 = 6.212x10^17
Replace x with 5 in each equation then subtract:
f(x) = 2(5)^2 - 4(5) = 30
g(x) = 5-2(5) = -5
f(x) - g(x) = 30 - - 5 = 30 +5 = 35
The answer is C. 35
Convert the mixed number into improper fractions, then find the LCD and combine. Exact form: 125/8 Decimal form: 15.625 mixed number form: 15 5/8..... hope this helps.. good luck
Answer:
-1/2
Step-by-step explanation:
Formula to find slope is y2-y1/x2-x1
Chose one ordered pair to be the 2 and the other one to be the 1
I chose the 2nd one to be 2.
Plug in the y-value from the 2nd ordered pair to y2 because its the 2.
Plug in the x-value from the 2nd ordered pair to x2 because its the 2.
Now you have 0-y1/5-x1
Do the same thing but for the 1.
Plug in the y-value from the 1st ordered pair to y1 because its the 1.
Plug in the x-value from the 1st ordered pair to x1 because its the 1.
Now you have 0-5/5--5
In this situation, you have 2 minus signs.
2 minus = 1 positive.
Now you have 0-5/5+5
Simplify.
Now you have -5/10.
Simplify.
-1/2.
Hope this helps!
