Answer: −50x−66
Step-by-step explanation:
4(10x+6)−10(9x+9)
Distribute:
=(4)(10x)+(4)(6)+(−10)(9x)+(−10)(9)
=40x+24+−90x+−90
Combine Like Terms:
=40x+24+−90x+−90
=(40x+−90x)+(24+−90)
=−50x+−66
∫f(6)-∫f(1) = 1, ∫f(6)-∫f(3)=6, and ∫f(7)-∫f(1)=7. Changing around the first and third equation, we can get ∫f(1)=∫f(6)-1, and ∫f(1)=∫f(7)-7. Then we get that ∫f(6)-1=∫f(7)-7, and that ∫f(6)=∫f(7)-6. Then plug into the second equation, to get ∫f(7)-6-∫f(3)=6 or ∫f(7)-∫f(3)=12. So <span>∫73f(x)dx = 12.</span>
16.) label the picture. the sign in the middle means they are congruent(equal or same)
7.) if it's asking for the midpoints then that's how you find it.
Answer:can yu help me get good at maths please
Step-by-step explanation:
Answer:
He can type 256 words in 4 minutes
Step-by-step explanation:
2 minutes 30 seconds is 2.5 minutes
The rate is the number of words divided by the time
160 words / 2.5 minutes =64 words per minute
We need to find how many words in 4 minutes
Take the rate time the time
64*4 =256
He can type 256 words in 4 minutes
