Answer:
= −21
Step-by-step explanation:
3(5−6)−2(4+5)
=(3)(−1)−2(4+5)
=−3−2(4+5)
=−3−(2)(9)
=−3−18
=−21
brainliest please? :)
Halo there!
The ratio of apples to all fruit is B. 7:15. Here's how to solve:
First, since they're asking for how many apples there are to the total pieces of fruit, add up 28 with 20 and 12:
28 + 20 = 48
48 + 12 = 60
Now, since they're asking specifically <em />for apples <em />to total pieces of fruit, we arrange the ratio in that specific order. Since we know there are 28 apples and 60 fruit in total, the ratio should look like this:
28:60
Finally, we need to simplify the ratio. 4 can fit into both 28 and 60, so let's divide both numbers down by 4 first:
28 / 4 = 7
60 / 4 = 15
7 and 15 don't have any common factors, so these numbers are already in their simplest form. The new ratio should look like this:
7:15
So the correct answer is B! I hope this helped you! :)

Step-by-step explanation:
To find the equation of the tangent to the given function, you must differentiate the function with respect to 'x'. The derivative (y prime) will give the tangent line at any point along the function. After we find the tangent equation, we let x equal zero which will alow us to find the slope at that point.
Begin by bringing the entire denominator to the top. If not, you'll have to do the quotient rule which is very annoying 99% of the time. You will get:
With this now, you can use the chain rule twice. Begin by differentiating:
Use the chain rule:
Use the chain rule again:
Simplify:
Let x = 0 to get:
