4x-2y=8 ==> y=2x-4 (to better show you what I mean)
2 lines are parallel if they have the same slope (m the coefficient of x).
So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b.
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
Yes it is a function
Y=x(x-1)
X(x-1)
X to the 2nd power -1x
Hope that’s helps
Answer:
he need to sell 200 tickets
Step-by-step explanation:
driks=500
we need 1000 more

Explanation: if you bring the fractions down as low as possible, the first bag has a 1 in 4 chance of getting a red marble. The 2nd bag can't be brought down anymore because 26 and 7 do not share any common divisors.
Answer:
1.14 days (approximately)
Step-by-step explanation:
Family drives 350 miles per day
Let d = days
Equation: 350d = 400
d = 400/350
d is approximately 1.14 days
If you want to answer it without decimals, you should say around 2 days since it's going to take more than one day to travel.
