Answer:
x-intercept: 4
y-intercept: -12
Step-by-step explanation:
Well our formula is y=mx+b where m is the slope and b is the y-intercept. -12 takes the place of the b, so -12 is the y-intercept.
To find the x-intercept, we need to make y=0.
0=3x-12
Add 12 to both sides
12=3x
Divide both sides by 3
x=4
The x-intercept is 4 and the y-intercept is -12.
Answer:
The answer is (4, 0), (0, -12)
y = 3x - 12
x-intercept:
y = 0
0 = 3x - 12
12 = 3x
x = 12/3
x = 4
Intercept: (4, 0)
y-intercept
x = 0
y = 3 * 0 - 12
y = 0 - 12
y = -12
Intercept: (0, -12)

HELP ME PLEASE REALLY IMPORTANT OR ILL GET IN TROUBLE!! WILL MARK AS BRAINLEST IF YOU GET IT CORRECT!!
Answer: C, It stays the same.
Step-by-step explanation: If you simplify the ratio (the fraction) by canceling the t's, you get 2/1 or 2:1. This means that no matter the value of the variable t, the value of the expression will stay the same.

Convert the decimal 0.83 to a fraction, and classify it as either rational or irrational
Answer:
83/100, rational
Step-by-step explanation:
A rational number is a number that ends. Even if it has decimals, the decimals have to end. 0.83 is a rational number because it doesn't continually go on.
To write it into a fraction, the easiest way is to take it out of a hundred, like a percentage.
Answer:
83/100
Rational.
Step-by-step explanation:
0.83 can be converted to a fraction.
83/100
The fraction cannot be simplified further.
It is rational because it can be written in the form p/q, where p and q are whole numbers.
Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is
designed to increase the likelihood that each baby will be a girl, but assume that the method has no effect, so the probability of a girl is 0.5.
Assume that the groups consist of 16 couples. Complete parts (a) through (c) below.
a. Find the mean and the standard deviation for the numbers of girls in groups of 16 births.
The value of the mean is u =
(Type an integer or a decimal. Do not round.)
Answer:
The found values are:
μ = 8
σ = 2
Step-by-step explanation:
Following data is given in the question:
p = 0.5
n = 16
Consider that it follows binomial distribution:
For binomial distribution, the mean is the product or probability 'p' and and the sample size 'n' :
μ = p · n
μ = 0.5 · 16
μ = 8
For binomial distribution, the standard deviation is the square root of product of sample size 'n' and the probabilities 'p' and 'q'.
σ = √(n·p·q)
where q = 1 - p = 1 - 0.5 = 0.5
σ = √(16 · 0.5 · 0.5)
σ = √4
σ = 2

y = 3x + 7
y = 3x - 7
y =

O y = fx-2
Answer:
y = 3x-7
Step-by-step explanation:
Lines that are parallel have the same slopes.
y = 3x-4 ---> y=mx+b (slope = m=3)
point-slope formula for a line: y - y1 = m(x-x1)
slope=m=3
(3,2)----> (x1,y1)
y - 2 = 3(x-3)
y - 2 = 3x-9
y = 3x-7

Answer:
D. [tex]x=-1, y=2\frac{2}{3}[/tex]
Step-by-step explanation:
Solving for x:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
Subtract 6 from both sides
2x-6= -3y
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
Subtract 12 from both sides
-4x-12= -3y
Combine equations:
-4x-12=2x-6
Add 4x to both sides
-12=6x-6
Add 6 to both sides
-6=6x
6x= -6
Divide both sides by 6
x= -1
Solving for y:
2x+3y=6
Subtract 3y from both sides
2x= -3y+6
-3y+6=2x
Multiply both sides by -1
3y-6= -2x
Multiply both sides by 2
6y-12= -4x
-4x+3y=12
Subtract 3y from both sides
-4x= -3y+12
-3y+12= -4x
Combine equations:
6y-12= -3y+12
Add 3y to both sides
9y-12=12
Add 12 to both sides
9y=24
Divide both sides by 9

Explain how you can determine that the following system has one unique solution – without actually solving the system.
2x+y=4
2y=6-2x
Answer:
Step-by-step explanation:
Well, first you'd have to get the equations in slope-intercept form in order to make it easier for you to see it in the bigger picture. 2x+y=4 would be y= 2x-4, and the other equation would be y= x-3. If you were to solve it, there would be one solution since the y's cancel out. If you graphed it, there would be a point of intersection, unlike when the lines are parallel if there's 0 solutions or only one line's there if there's infinitely many solutions.

Please help!! This is so confusing! 100 points!!
Answer:
The value of the expression given is:
4Step-by-step explanation:
First, you must divide the expression in three, and to the final, you can multiply it:
[(3^8)*(2^(-5))*(9^0)]^(-2) [(2^(-2))/(3^3)]^4 3^28Now, we can solve each part one by one:
First part.
3^8 = 6561 2^(-5) = 0.03125 9^0 = 1 (Whatever number elevated to 0, its value is 1) (6561 * 0,03125 * 1) = 205.03125And we elevate this to -2:
205.03125^-2 = 2.378810688*10^(-5) or 0.00002378810688Second part.
2^(-2) = 0.25 3^3 = 27 0.25 / 27 = 9.259259259 * 10^(-3) or 0.00925925925925And we elevate this to 4:
0.00925925925925^4 = 7.350298528 * 10^(-9) or 0.000000007350298528Third Part.
3^28 = 2.287679245 * 10^13 or 22876792450000At last, we multiply all the results obtained:
0.00002378810688 * 0.000000007350298528 * 22876792450000 = 3.999999999999999999 approximately 4We approximate the value because the difference to 4 is minimal, which could be obtained if we use all the decimals in each result.

2x − 5y = 16
3x + 2y = 5
can you also explain how you did it. Thanks :)
Answer:
x=3
y=-2
Step-by-step explanation:
2x - 5y = 16
3x + 2y = 5
Solve for x in the first equation.
2x - 5y = 16
2x = 16 + 5y
x = (16 + 5y)/2
x = 8 + 5/2y
Put x as 8 + 5/2y in the second equation and solve for y.
3(8+5/2y) + 2y = 5
24+15/2y + 2y = 5
24 + 19/2y = 5
19/2y = 5-24
19/2y = -19
y = -2
Put y as -2 in the first equation and solve for x.
2x - 5(-2) = 16
2x +10 = 16
2x = 16-10
2x = 6
x = 3
