Answer:

The correct answer is 5y-7

Step-by-step explanation:

Given that a quadratic expression is in the form ax²+bx+c where a,b and c are integers, we can factorize as follows

To factorize the expression 5y^2-12y+7, we need to find two numbers that when multiplied we get 5×7, that is ac, and that when added they give us -12 which is b,

these numbers are -7 and -5

therefore, 5y²-5y-7y+7 is our expression

Factorizing we get

             5y(y-1)-7(y₋1)

This gives  (y-1) (5y-7) as the factorized form of 5y²₋12y+7

Therefore the missing factor is 5y-7

Complete the missing parts of the table for the following function. y=7x​
IgorC [24]

Answers:   49,   1,   49

Those values go in the blanks from left to right

=====================================================

Explanation:

The rule we use is x^(-k) = 1/(x^k)

That means if we're evaluating something like 7^(-1), then it's the same as 1/(7^1) = 1/7 which explains how x = -1 leads to y = 1/7.

Similarly, 7^(-2) = 1/(7^2) = 1/49 is the y value when x = -2. So you'll type 49 into the first box to fill in that missing denominator.

Raising any nonzero value to the zeroth power leads to 1. That rule is x^0 = 1 where x can be anything you want but it can't be zero. Therefore 7^0 = 1 goes in the second box.

Lastly, 7^2 = 7*7 = 49 will go in the third box.
