Passing through (1,9),slope=2

Passes through (1, 9) with a slope of 2.

Assuming that we want this in slope intercept form, which is y=mx+b (m=slope, b=y-intercept) then we need to find the y-intercept! :)

To find the y-intercept (or b!!) you simply need to plug everything into slope intercept form using our given points.

y = mx + b

Plug everything in.

9 = 2(1) + b

Simplify.

9 = 2 + b

Subtract 2 from both sides.

9 - 2 = b

b = 7

Therefore, our y-intercept is 7! :)

Now that we have both the y-intercept and the slope, we can finally plug this into a new equation, using slope intercept form.

y = mx + b

y = 2x + 7

~Hope I helped!~

y = ax + b

Here the slope is 2.

Then, y = 2x + b

The line is passing through (1;9).

We just have to substitute that in the equation.

9 = 2*1+ b
b = 9 - 2 
b = 7

That's the intercept.

Eventually, the equation is : y = 2x + 7

Hope this helps !

The question asks:
_______________________________
"<span>What is the product of (3√8)(4√3)? Simplify your answer/

First, let us simplify:  "</span>√8" 

"√8 = √4*√2 = 2√2 ;

So, "3√8 = 3*2√2 = 6√2" .

So, "what is the product of "(3√8)(4√3)"?  

Rewrite, replacing the "(3√8)" with "6<span>√2" ; as follows:

</span>6√2* 4√3 = 6*4 *√2*√3 = 24 *√(2*3) = 24√6 .

Answer:

C and D

Step-by-step explanation:

1

The arc length is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × \frac{60}{360}

     = 2π × 10 × \frac{1}{6} = \frac{20\pi }{6} = \frac{10\pi }{3} cm → C

-----------------------------------------------------

2

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

   = πr² × \frac{60}{360}

   = π × 10² × \frac{1}{6} = \frac{100\pi }{6} = \frac{50\pi }{3} cm² → D

kipiarov [429]
The perimeter of a rectangle:
P = 2 L + 2 W
where L is the length and W is the width.
The area of a rectangle:
A = L x W
7/10 = L x 4/5
L = 7/10 : 4/5 = 7/10 * 5/4
L = 7/8 in
P = 2 * 4/5 + 2 * 7/8 = 8/5 + 14/8 = 64/40 + 70/40 = 134/40 = 3 14/40 =
= 3 7/20 < 3 1/2
Answer:
A silver line is long enough to outline the stone.
