Answer:
I dont know what options you have but all these are possible answers
y - 5 = 1/2 ( x - 4 )
y - 3 = 1/2 x
y = 1/2 x + 3
Step-by-step explanation:
In order to find the equation you need a slope, so you find the slope of both points by using the slope equstion
y2 - y1 / x2 - x1
and you would get :

now you plug it into the point slope formula which is y - y = m ( x - x )
and you choose one of the two sets of points that they provided in the question but you'll get the same answer either way.
4/3
Remember if two lines are perpendicular, the product of their slopes are -1
Answer:
$16
Step-by-step explanation:
Let his weekly allowance = x
Amount spent playing golf = x / 2
Amount earned for cleaning car = $4
Final amount at hand = $12
Mathematically ;
x/2 + 4 = 12
x/2 = 12 - 4
x/2 = 8
x = 2 * 8
x = $16
Weekly allowance = $16
Answer:
k= -29
Step-by-step explanation:
The formula for the surface area of a prism is
A = 2 (wh + wl + lh)
where A is the surface area
w is the width
l is the length
h is the height
w = 8 x 2 = 16
l = 6 x 2 = 12
h = 4 x 2 = 8
substitute to the given formula
A = 2 ( (16 x 12) + ( 16 x 8 ) + ( 12 x 8) )
A = 832 sq cm is the surface area of the new rectangular prism
