x is always +3 ahead (30-27=3)
and y is always trailing behind x by -3
Answer:
y = x - 3
Step-by-step explanation:
You are given an x and a y and need to find the difference.
Set up a formula using one of the given x and y pairs and solve.
y = x - u plug in an x and y and solve for the unknown(u)
27 = 30 - u
-3 = -u
u = 3
Now plug the unknown into the original equation
y = x - 3

Step-by-step explanation:
Gareth believes that if he flips a coin 820 times, it will land heads up exactly 410 times. What would you tell Gareth about his prediction?
Answer:
What I would tell Gareth is that his prediction is somewhat right because there is a 50/50 chance of landing the coin on each side because 410 is half of 820.

x2+7x+12=0 please help
Answer:
x has the values -4 and -3
Step-by-step explanation:
x² + 7x + 12 = 0
x² + 3x + 4x + 12 = 0
x(x + 3) + 4(x + 3) = 0

What’s the solution for y=2x+7 y=3x-1
Answer:
x=8 and y=23
Step-by-step explanation:
Rewrite equations:
y=2x+7;y=3x−1
Step: Solve y=2x+7 for y:
y=2x+7
Step: Substitute 2x+7 for y in y=3x−1:
y=3x−1
2x+7=3x−1
2x+7+−3x=3x−1+−3x(Add -3x to both sides)
−x+7=−1
−x+7+−7=−1+−7(Add -7 to both sides)
−x=−8−x−1=−8−1
(Divide both sides by -1)
x=8
Step: Substitute 8 for x in y=2x+7:
y=2x+7
y=(2)(8)+7
y=23(Simplify both sides of the equation)
Can somebody solve this: x^4+2x^3-25x^2-26x+120
Answer:
(x + 5) • (x + 3) • (x - 2) • (x - 4)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5
x2 + 3x + 5x + 15
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+3)
Add up the last 2 terms, pulling out common factors :
5 • (x+3)
Step-5 : Add up the four terms of step 4 :
(x+5) • (x+3)
Which is the desired factorization
(x + 5) • (x + 3) • (x - 2) • (x - 4)
The admission ticket for Pat Pat Zoo is $1.50 for children and $4.00 for adults. On a certain day, 2200 people went to the zoo and $5050 was collected. How many children and how many adults went to the zoo that day?
Answer:
1380 children and 820 adults went to the zoo that day
Step-by-step explanation:
System of Equations
Define the following variables
x = number of children that went to the zoo
y = number of adults that went to the zoo
On a certain day, 2000 people went to the zoo, thus:
x + y = 2000
Solving for x:
x = 2000 - y [1]
The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:
1.50x + 4y = 5050 [2]
Substituting x from [1]:
1.50(2000 - y) + 4y = 5050
Operating:
3000 - 1.50y + 4y = 5050
3000 + 2.5y = 5050
Subtracting 3000
2.5y = 5050 - 3000 = 2050
Dividing by 2.5
y = 820
From [1]
x = 2200 - 820 = 1380
1380 children and 820 adults went to the zoo that day
