Well this is a little tricky.. But my guess would be: <span>y = (-1.4, 2.5)</span>

What you need to do to solve this problem is by using the FOIL Method (First, Outside, Inside, and Last) Here are the steps into doing this problem.
Given Answer: (2y-5)(5y-7)
Next, you multiply by the order that has been given: 10y^2 + 14y -25y - 35
After you got the numbers and coefficients, you can combine like terms if necessary: 10y^2 - 11y - 35
Therefore, your answer should be 10y squared - 11y - 35.
I hope this helps. :)

Two integers, a and b have a product of 15. what is the least possible sum of a and b?

Neporo4naja [7]

If they're integers, that means they can't be fractions (such as 15/2 and 2).

So the only couples of integers that, when multiplied, result in 15 are:

1 and 15
5 and 3.

(there are no other possibilities as both 5 and 3 are not divisible further).
The smaller of the two sums (15+1; 5+3) is 5+3=8.

The least possible sum of a and b is 8.

A scientist used a microscope to count the number of bacterial cells in a petri dish every hour. The graph shows the data collec

Alex777 [14]

The required relationship shown by the graph is the exponential relationship $n =2^t$ . Option a is correct,

Given that,

A graph has been shown, showing the data, what is the relationship between the number of bacteria with time is to be determined.

<h3>What is a graph?</h3>

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Since the recorded value from the graph is
At, t = 1 ; n = 2
At t = 2 ; n = 4
At t = 3 ; n = 8
At t = 4 ; n = 16
At t = 5 : n = 32
Here the above data show the exponential relation between n and t with the base value 2 i.e. $n =2^t$

Thus, the required relationship shown by the graph is the exponential relationship of $n =2^t$ . Option a is correct,

Why is there no commutative property for subtraction and division

Bezzdna [24]

There is no commutative property for subtraction and division because order does matter. 6 - 5 will not give you the same answer as 5 - 6.
