Answer:
x=6
y=-5
Step-by-step explanation:
3x+2y=8 equation 1
x-2y=16 equation 2
equation 2+equation1 ; 4x = 24
x = 6
substitution x in equation1 ;
18+2y=8
2y = -10
y = -5
X = -13 :)

Hey there! :)
Perpendicular to y = -3x + 5 ; passes through (2, 6).
Our slope is -3. We know this because it is in the "m" position from slope-intercept form. However, since our equation we're looking for is perpendicular to our given one, we must find the negative reciprocal of -3.
A negative reciprocal is simply a number that is flipped and either given a negative or gets a negative removed.
So the negative reciprocal of -3 is 1/3. This means that our new slope is 1/3.
Now, using point-slope form ( y-y₁=m(x-x₁) ), our new slope (1/3) & (2, 6) , let's find our new equation!
y-y₁=m(x-x₁) y - (6) = 1/3(x - 2)
Simplify.
y - 6 = 1/3x - 2/3

Answer:
There is nothing to be further simplified. It is how you wrote it. Let me know if it was a mistake I'll edit my answer.
Step-by-step explanation:
Answer:
There were 300 people at the meeting
Step-by-step explanation:
The number of people who drove to the meeting is equal to the number of people at the meeting times the percentage of people who drove
240 = people *80%
Change this to a decimal
240 = people *.8
Divide each side by .8
240/.8 = people *.8/.8
300 = people
There were 300 people at the meeting
