can anyone explian this?
Answer: y=1/2x+3
m is the slope in the equation y=mx+b. you find b by plugging in (8,7) into the equation y=1/2x+b. Plug in 7 for y and 8 for x. The equation will look like 7=1/2(8)+b. solve for b. b should equal 3.
so your answer is y=1/2x+3
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.

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

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

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)

41/19 as a decimal rounded to the nearest hundredth
The decimal rounded to the nearest hundredth is 2.16
What is Decimal?A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.
Given:
41/19
Now, dividing the fraction
41/19
= 2.1578
Now, rounding off to nearest hundredth focus on thousandth place value whether it is greater than 5 or not.
Hence, the decimal rounded to the nearest hundredth is 2.16

41/19
= 2.1578
2 = one place value
1 = tenth place value
5 = hundredth place value
7 = thousandth place value
8 = ten thousandth place value.
The value of 41/19 as a decimal rounded to the nearest hundredth is 2.16.
What is place value?The place value of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 = thousandths place value
We have,
41/19
2.1578
5 is in the hundredth place value.
Rounding to the nearest hundredth-place value.
Since the thousandth place value is greater than 4.
We have,
2.16
Thus,
The value of 41/19 as a decimal rounded to the nearest hundredth is 2.16.
