Equation: 8=4b
b=2
Explanation:
The green line equals 8 and the black time equals 2b+2b. So to form an equation where the green line equals the black line it would look like: 8=2b+2b
8 being the green line
2b+2b being the black line
Then the directions tell us to combine like terms, like terms are terms that are the same such as 2b in this problem, and to combine them means to add them together.
So, 2b+2b= 4b
So the answer is, 8= 4b
In order to solve this equation divide both sides by 4.
Which leaves you with: 8/4= b
Now solve 8/4:
Which gives you:
b=2

please mark my answer as brainliest:
7/100, 1/19
1/20, 7/80
Step-by-step explanation:
firstly, figure out the total amount of students:
5+7+4+4=20
remember that dependant variables means you have to multiply the values
a)
figure out probability of choosing a green eyed student:
4/20
figure out probability of choosing a brown eyed student:
7/20
multiply values:
4/20 x 7/20 = 7/100
b)
probability of choosing a blue eyed student:
5/20 = 1/4
probability of choosing another blue eyed student:
4/19 (bc theres 1 less)
multiply:
1/4 x 4/19= 1/19
PART 2
a)
probability of choosing a hazel eyed student:
4/20
probability of choosing a blue eyed student:
5/20 = 1/4
multiply:
4/20 x 1/4 = 4/80= 1/20
b)
probability of choosing a brown eyed student:
7/20
probability of choosing a blue eyed student:
5/20 = 1/4
multiply:
7/20 x 1/4 = 7/80

When Janya was in 6th grade, she invested $1000 into an account that earns 15% interest, compounded quarterly. Six years later, she is a senior and she wants to withdraw the interest earned to help with college expenses. She will learn the initial investment of $1,000 in the account. How much will she withdraw?
a. $2,419
b. $1,150
c. $1,000
d. None of the above
Answers
The amount she will withdraw is $2,419.44. (option d)
How much will she withdraw?The interest earned in the account is the difference between the amount invested and the future value of the investment.
Interest earned = future value - amount invested
The formula for calculating future value:
FV = P (1 + r)^nm
Where:
FV = Future value P = Present value R = interest rate = 15%/4 = 3.75%m = number of compounding= 4N = number of yearsFV = 1000 x (1 + 0.0375)^(6 x 4)
= 1000 x (1.0375^24) = $2,419.44
Interest earned = $2,419.44 - $1000 = $1,419.44

A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?
Answers
Answer:
y=1/6x-6
Step-by-step explanation:
The first step is to set up the equation. Since the lines are parallel the slopes will be the same.
Note: y=mx+b; m is the slope and b is the y-intercept
Since we know that the slopes are the same all we have to do is plug in (12,0) in the equation to find b (y-intercept),
0=1/6(12)+b
0=6+b
-6=b
Now that we know b all we have to do is put it in the formula y=mx+b
y=1/6x-6.
Answer:
y = (1/6)x - 2
Step-by-step explanation:
"Parallel" means "has the same slope as..." so the slope of the line you want is 1/6.
y = (1/6)x + b where b is the y-intercept (now, find it using the point (12, 0) ).
0 = (1/6)(12) + b
0 = 2 + b
b = -2
The equation is y = (1/6)x - 2

Answers
The solution if h(x) = g(x) is ±1
Solution to set of functionsGiven the following functions
h(x)=1+2x/x
g(x)=2+x
The solution of the function occur at h(x) = g(x)
If h(x) = g(x), then;
1+2x/x = 2 + x
Cross multiply
1+2x = x(2+x)
1 + 2x = 2x + x^2
Equate the resulting expression to zero to have;
x^2 = 1
x = ±1
Hence the solution if h(x) = g(x) is ±1

y is directly proportional to x^2
If y = 8 when x = 2
find x when y = 32
Answers
Answer:
4 or -4
Step-by-step explanation:
Y is directly proportional to x^2 means there is a constant, k, such that y=kx^2.
We are given y=8 when x=2. This information will allow us to find k in the equation y=kx^2.
8=k(2)^2
8=k(4)
This implies k=2 since 2(4)=8.
So the equation for any pair (x,y) is y=2x^2.
We want to find x when y=32.
32=2x^2
32/2=2x^2/2
16=x^2
This implies x=4 or -4.
