A changes saved<br> Set up a proportion and use it to solve for x.<br> 2<br> 10<br> х<br> 3
V125BC [204]

Answer:

C. 15

Step-by-step explanation:

The following proportional can be set-up for the figure given:

\frac{x + 3}{x} = \frac{10 + 2}{10}

Solve for x

\frac{x + 3}{x} = \frac{12}{10}

\frac{x + 3}{x} = \frac{6}{5}

Cross multiply

5(x + 3) = x(6)

5x + 15 = 6x

15 = 6x - 5x

15 = x

x = 15

How would you write y=2/3x+1/3 in point slope form??
gladu [14]

Answer:

y - 1 = 2/3(x - 1).

Step-by-step explanation:

Point slope form is y - y1 = m(x - x1) where m = the slope and (x1, y1) is a point on the line.

y = 2/3x + 1/3   which gives the slope m = 2/3.

We can now find a point on the line by putting x = 1 say then find y:

y  = 2/3(1) + 1/3  =  2/3 + 1/3 = 1 so  the point is (1, 1).

(x1, y1) = (1, 1)

So the answer is ;

y - 1 = 2/3(x - 1).
