Answer:

X=18

Step-by-step explanation:

$\frac{9}{x} = \frac{1}{2} \\ 9 \times 2 = x \times 1 \\ x = 18$

Answer:

$y=-10x+89$

Step-by-step explanation:

Remember that the derivative tells us the slope of the tangent line at a given point.

So, we want to find the equation of the tangent line to f(x) at x=8.

We are given that f'(8) is -10.

In other words, the slope of the tangent line to f(x) at x=8 is -10.

We also know that f(8)=9. In other words, we have the point (8,9).

So, we can use the point-slope form to figure out the equation:

$y-y_1=m(x-x_1)$

Substitute -10 for m and let (8,9) be (x₁, y₁). So:

$y-9=-10(x-8)$

Distribute the -10:

$y-9=-10x+80$

Add 9 to both sides:

$y=-10x+89$

And we're done!

Xiao's teacher asked him to rewrite the sum 60+90 as the product of the GCF of the two numbers and a sum. Xiao's wrote 3(20 + 30

Kobotan [32]

His answer works ... it gives 150, which is the same as (60 + 90) ... but he didn't deliver exactly what the problem asked for.

It asked for the <u>GCF</u> to be outside the parentheses, and he put '3' there.

'3' is certainly one common factor of 60 and 90, but it's far from being the
greatest one.

The GCF of 60 and 90 is actually 30 . So the absolutely positively technically correct response to the instructions in the problem would be 30(2 + 3).
