Tn = a + (n-1)d

when n  = 12, tn  = 63

63 = a + (12-1)*5

a = 63 - 55 =8

tn or an 
= 8 + (n-1) 5

=  3 + 5n

Hope this helps

Cameron ran 3.8 miles per every 1.9 miles that Samantha ran and if Samantha and 7.6 miles how far did Cameron run
bija089 [108]
3.8 / 1.9 = x / 7.6....3,8 miles to 1.9 miles = x miles to 7.6 miles
cross multiply
(1.9)(x) = (3.8)(7.6)
1.9x = 28.88
x = 28.88 / 1.9
x = 15.2 <== Cameron ran 15.2 miles

What is a correct equation for the line passing through the point (-2,1) and having slope m=1/2
frez [133]

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

y-1=\dfrac{1}{2}(x-(-2))

y-1=\dfrac{1}{2}(x+2) - point-slope form

Covert to the slope-intercept form (y = mx + b):

y-1=\dfrac{1}{2}(x+2)          <em>use the distributive property</em>

y-1=\dfrac{1}{2}x+1          <em>add 1 to both sides</em>

y=\dfrac{1}{2}x+2   - slope-intercept form

Convert to the standard form (Ax + By = C):

y=\dfrac{1}{2}x+2     <em>multiply both sides by 2</em>

2y=x+4        <em>subtract x from both sides</em>

-x+2y=4         <em>change the signs</em>

x-2y=-4   -  standard form

Convert to the general form (Ax+By+C=0):

x-2y=-4        <em>add 4 to both sides</em>

x-2y+4=0   - general form
