Answer:

To know the y values in of both the tables I have

y=2.25x.

To get the equation y=2.25x, I need to get the value of y divide by the value of x, repeat this process for both of the tables. You can see that they are all proportional to each other.

For the first table we have:

360÷160=2.25, 1125÷500=2.25, 2700÷1200=2.25

In order to form a equation they all have to have the same proportion.

Then, there you have it.

y=2.25x

For the second table we have:

4.5÷2=2.25, 11.25÷5=2.25, 15.75=2.25

y=2.25x

to check if the equation is right

y=2.25(160)=360 (for the first table)

y=2.25(500)=1125

y=2.25(1200)=2700

What are the roots of this quadratic equation? 3x^2+10=4x

____ [38]

Step-by-step explanation:

The root of an equation is when x=0.

We need to rewrite this as 3x²-4x+10=0.

The quadratic formula is

(-b+or-sqrt(b²-4ac))/2a

so 4+or-sqrt(16-120)/2a

since the sqrt can no be negative this answer will have imaginary numbers.

(4+2i sqrt(26))6 and (4-2i sqrt(26))6

simplified is

x=(2+i sqrt(26))/3 and x=(2-i sqrt(26))/3

damaskus [11]

Answer:

$F(x) = f \circ g$

$f(x) = x + 2$ and $g(x) = x$

Step-by-step explanation:

Given

$F(x) = x + 2$

Required

Express as

$F(x) = f \circ g(x)$

In functions:

$f \circ\ g(x) = f(g(x))$

So, we have:

$f(g(x)) = x + 2$

g(x) can be set to x and f(x) to x + 2

Hence:

$F(x) = f \circ g$

When: $f(x) = x + 2$ and $g(x) = x$
