It would be y=-7x-6 if it where parallel, and it would be y=7x-6

Which of the following is an equation of the line that crosses through (-3,4) and (3,6)?
Mama L [17]

Answer:

y=(1/3)x+5

Step-by-step explanation:

Slope-intercept: y=mx+b

m=((y2-y1)/(x2-x1)) = (6-4)/(3+3)= 2/6= (1/3)

y=(1/3)x+b

plug in one of the points (3,6)

6=(1/3)(3)+b

6=1+b    5=b

Please help me?? Solve for x
Delvig [45]
X= 10

This is because 180-95= 85 which would make 8x+5= 85

Subtract 5 from both sides and get 8x=80

Then, divide 8 from both sides and get x=10

Y= x^2 -5 solve for x
dexar [7]

Y= x^2 -5

We need to solve for x, we need to get x alone

Y= x^2 -5

Lets start by removing -5

Add 5 on both sides

y + 5= x^2 -5 + 5

y + 5= x^2

Now to isolate x , we need to remove the square from x

To remove square , take square root on both sides

+-\sqrt{y+5} = \sqrt{x^2}

square and square root will get cancelled

+-\sqrt{y+5} = x

So x = +\sqrt{y+5} and  x = -\sqrt{y+5}

less than: 2's, 1's

greater than: 0's

question 20

40 gallons, 12 concentrate, 28 water

this is a fraction of 12/28

simplification: (12) divided by 12 / (28) divided by 12

1/2

1 part concentrate 2 parts water per each of the 40 total gallons.

so color in 33% for concentrate and 66% water

I am totally not wrong  :D:D:D:D
