Answer: It's hard to explain without a grid...

The grid method is a written method used to teach children multiplication. It involves partitioning numbers into tens and units before they are multiplied. In some schools the grid method is referred to as the box method of multiplication because children learn to partition numbers into a grid of boxes.

Consider the function represented by the equation y – x – 4 = 0. What is the equation written in function notation, with x as th

pochemuha

Answer: First option.

Step-by-step explanation:

Given the equation $y-x-4=0$ , you need to substitute $f(x)=y$ into this equation. Then:

$f(x)-x-4=0$

Remember that the Addition property of equality states that:

$If\ a=b\\then\ a+c=b+c$

Then, you can add "x" and 4 to both sides.

Therefore, you get the equation written in function notation, with "x" as the independent variable:

$f(x)-x-4+(4)+(x)=0+(4)+(x)\\f(x)=x+4$

If y varies directly as x and given y =9 when x= 5, fInd:

True [87]

Step-by-step explanation:

The statement

y varies directly as x is written as

<h3> $y \: \: \alpha \: \: x$ </h3>

So we have

<h3>y = kx</h3>

First of all we must find the relationship between them

when

x = 5 and y = 9

We have

9 = 5k

Divide both sides by 5

$k = \frac{9}{5}$

So the equation for the variation is

$y = \frac{9}{5} x$

<h2>b).</h2>

when x = 15

$y = \frac{9}{5} \times 15 \\ = 9 \times 3$

We have the answer as

<h3>y = 27</h3>

<h2>c).</h2>

when y = 6

$6 = \frac{9}{5} x \\ 30 = 9x \\ x = \frac{30}{9}$

We have the answer as

$x = \frac{10}{3}$

Hope this helps you
