a line with slope 3 passes through point (0,10). What is the y-coordinate of the point on the line with x-coordinate 2

skad [1K]

The y-coordinate is 16

<h3>Solution:</h3>

Given that a line with slope 3 passes through point (0, 10)

To find the y-coordinate of the point on the line with x-coordinate 2

Which means the point is (2, y)

Let us find the required y co-ordinate using slope formula

The slope of line is given as:

For a line containing points $(x_1 , y_1)$ and $(x_2 , y_2)$ is given as:

$\text {slope}=m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$\text {Here } x_{1}=0 ; y_{1}=10 ; x_{2}=2 ; y_{2}=y$

Given that slope "m" = 3

Substituting the values we get,

$\begin{array}{l}{3=\frac{y-10}{2-0}} \\\\ {3=\frac{y-10}{2}} \\\\ {6=y-10} \\\\ {y=10+6=16}\end{array}$

Thus the y-coordinate is 16

Subtract. (11x2+3x−9)−(2x2+2x+7)

Alexeev081 [22]

Answer:

-267

Step-by-step explanation:

this is because 11 ×2=22,22+3=25,25×-9= -225 and then the other bracket when I solved I had 42 and so -225-42 = -267

A = πr2S 360 i need the answer asap solve for S

Tresset [83]

$\sf a=\pi r^2s\times360\\Divide\ by\ \pi r^2\times360\\ \frac{a}{\pi r^2\times360}= \frac{\pi r^2s\times360}{\pi r^2\times360}\\ \frac{a}{\pi r^2\times360}=s\\\\{\boxed{\sf s=\frac{a}{\pi r^2\times360}}$
