Answer:
8x-7x^2-39
Step-by-step explanation:
Because people want points, so they answer as many questions as they can... it's quite stupid (and annoying), if you ask me.
Since the functions are not included, I can help you with some examples and a general explanations which will help you to solve this kind of problems.
1) Assumption: all the functions that are considered are linear.
That means that f(x) = x is the parent function, and you can obtain the other functions by a set of transformations (translation and scalation) of the parent function.
2) Example 1: y = x + a
This is a special case of adding a constant to the function.
In this case, the graph of the new function is the graph of the parent function shifted a units upward.
3) Example: y = 5x
This is a special case of multiplying the function times a constant.
The result is streching the graph vertically by the same scale factor.
4) Example: y = (1/5)x - 8
In this case, the graph of y is obtained by scaling the parent function f(x) = x by 1/5 (which results in compressing the parent function vertically) and shifting the parent function 8 units downward.
Answer:
1200 copies
Step-by-step explanation:
In order to find how many copies can be printed in 10 minutes, first we need to find how many copies the machine can print in one minute. Let that be x.
480= 4x
Divide both sides by 4
120=x
Now, we need to multiply that by how many minutes we need to find.
120* 10= 1200
Thus, the machine can print 1200 copies in 10 minutes.
Answer:
u + v = < 8, 3 >
Step-by-step explanation:
u + v
= < 7, 4 > + < 1, - 1 > ← add corresponding components
= < 7 + 1, 4 - 1 >
= < 8, 3 >
