Answer:
y= -7/4
Step-by-step explanation:
-2-y=3y+5 (subtract 5 from both sides)
-7-y=3y (add 1y to both sides)
-7=4y (divide by 4)
y= -7/4

1,3,5
Answer:
x= 6
Step-by-step explanation:
Step 1: Write equation
2x - 5 = 7
Step 2: Solve for <em>x</em>
<u>Add 5 to both sides:</u> 2x = 12
<u>Divide both sides by 2:</u> x= 6
<u />
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
2(6) - 5 = 7
12 - 5 = 7
7 = 7
The equation is y^2=16x and the directrix is x=-4
Answer:
the correct answer is (-7,-2,7,0)
