1.50 that should be it and i dont know how to show my work on a computer SORRY.
Answer:
Slope of a line passing through (
,
) and (
) is given by:
Now,
Slope of line L, (m) = 
= 0.5
Slope of line M, (n) = 
= 
If the lines L and M are parallel to each other,
m = n
or, 0.5 =
or, 0.5 (W - 1) = -2
or, W - 1 = -4
or, W = -3
Therefore the required value of W is -3.
Answer:
8 dollars
Step-by-step explanation:
20/100 = x/10
100x=20
x=2
You save two dollars
10-2 = 8
$8
Answer:
2. (3/6)/4 = 1/8
3. (1/3)/(1/4) = 4/3
Step-by-step explanation:
To solve these expressions, simply solve them by multiplying the reciprocal of the bottom number times the fraction in the numerator:
2. (3/6)/4
3/6 x 1/4
3/24
1/8
3. (1/3)/(1/4)
1/3 x 4
4/3
Answer:
1). The constant of variation is 7
2). w = 6 for the given values of x and y
Step-by-step explanation:
"Varies jointly" tells us that y is a direct result of a mathematic operation involving x and w. We will assume y is directly prorportional to x and w, in the sense that we can find a multiplicative relationship of the form y=Kxw, where K is the constant of variation.
We are given one data point: y=-42 where x is 2 and w is -3. Let's put those values into our trrial expression:
y=Kxw
-42=K(2)(-3)
-42 = -6K
K = 7
<h2>The expression becames <u>
y = 7xw</u></h2>
The constant of variation is 7.
The value of w for y=3 and x=(1/14) would be:
y=7xw
3 = 7*(1/14)*w
3 = (1/2)*w
<h2><u>
w = 6</u></h2>
