Answer:
im pretty sure the answer is either a or c because. if i had to choose one though i'd probably go with C
Step-by-step explanation:
a function is a y for every x and im pretty sure both a and c display that, but a is going to all of numbers in the other bubble and there arent any other letters in the first one. hope this helps
Answer:
x = 5/3
y = -8/3
Step-by-step explanation:
To solve y = 2x - 6 substitute the y for -x - 1 and solve for x.
-x - 1 = 2x - 6 Now you can solve this like a regular inequality. Start by subtracting 2x on both sides.
-3x - 1 = -6 Now add 1 to both sides
-3x = -5 Divide by -3 on both sides
x = 5/3 (the negatives cancel and become positive)
Because you have x, you can go back and properly solve for y. Substitute x for 5/3
y = 2(5/3) - 6 Simplify the right side to get your answer.
y = 10/3 - 6 In order to subtract 6, you first have to convert it to a fraction with a denominator of 3. To do this, put 6 over 1 (6/1) then find the least common denominator of 3 and 1, which is 3. Now multiply 1 by 3 and 6 by 3 to get 18/3
y = 10/3 - 18/3
y = -8/3
I hope this helped :)
<span>-9 divided by 5/8 equals
-9 / (5/8) <---</span><span>Turn the second </span>fraction<span> upside down, then multiply.
= -9 * 8/5
= -72/5
= -14 2/5
= -14.4</span>
If it’s to be solved in terms of x then it would be x=(3d+9)/(d-k)
