Answer: this is wrong. The final answer should be x - 4y = 8
Step-by-step explanation:
y = 1/4x + 2
We'll first isolate the constant
-1/4x + y = 2
We remove the fraction by multiply through both sides of the equation
-4
x - 4y = 8
Answer:
y= -1.4x-6.6
Step-by-step explanation:
(1,-8)
7x+5y=-7
Make the equation into standard form
Subtract 7x from both sides
5y=-7x-7
Divide all by 5
y=-1.4x-1.4
Since they are parrallel, we know the slope is -1.4x
y=-1.4x+b
(1,-8) is one of the points it goes through
Replace the x and y in the equation for the x and y in the incomplete equation
-8=-1.4+b
Add 1.4 to both sides
-6.6=b
Thus the equation is
y=-1.4x-6.6
The sample space is all the possible outcomes from a trial/trials;
In this case, it is all the possible coins that you can pick from;
If you are picking multiple coins, how many of each and in what order you pick them also contribute to the sample space, i.e. they produce other possible outcomes:
<span>7 quarters, 2 dimes, 5 nickels or 11 pennies.

<span>six hundred thirty-two thosuandths and .6 +.03 + .002</span>
