Answer:
<h3>-3</h3>
Step-by-step explanation:
For two parallel lines. their slope are equal
Find the slope of each of the lines
For line A;
m = 0 -y/0+1
mA = -y/1
For line B;
mB = 9 - 3/8 - 6
mB = 6/2
mB = 3
since their slope are equal hence mA = mB
-y/1 = 3
-y = 3
y = -3
Hence the value of y is -3
Easiest way I could think of is choose a point in the gray area and use the X,Y to plug into the answers whichever one makes sense is correct.
To do it without a calculator:
10% of 67 is 6.7
6.7 x 8 is 53.6 (80%)
1% of 67 is .67
53.6 - .67 is 52.93 (79%)
Answer: A or 1:4
Step-by-step explanation: Since its 16 servings and the recipe is 8, you just multiply everything by 2. Since 1/2 * 2 = 1 and 2 *2 = 4, it would be 1:4
Answer:
So we know that y=1/2x. So we apply this equation on each x.
x=-2, so y=1/2*-2 which is -1. so y = -1
x=0, so y = 1/2 * 0 which is 0. so y=0
x=2, so y = 1/2*2 which is 1. so y=1
Hope this helps :))
