Answer:

y = 3, y = 5, y = -1

Step-by-step explanation:

What you do is you substitute the x values into the x.

y + 2(-1) = 5

y + -2 = 5

y = 3

y + 2(0) = 5

y = 5

y + 2(4) = 5

y + 6 = 5

y = -1.

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number

mixas84 [53]

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.

The size of the sample space is: (8, 16, 20, 24)

If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is: (1/8, 1/6, 1/3, 2/5, 2/3)

If a code is chosen at random, the probability that D is in the code but is not in the first position is: (1/8, 1/6, 1/3, 2/5, 2/3)

Q4: Write the equation in slope-intercept form of the line that is perpendicular to

forsale [732]

Answer:

5y = x + 11

Step-by-step explanation:

Given parameters:

Equation of the line ;

y = -5x + 1

Coordinates = (2, -1)

Find the equation of a line perpendicular;

Solution:

A line perpendicular to y = -5x + 1 will have slope that is a negative inverse of the given one.

Equation of a straight line is expressed as;

y = mx + c

y and x are the coordinates

m is the slope

c is the y-intercept

So, the slope of the new line perpendicular is $\frac{1}{5}$ ;

Now let us find the y-intercept of the new line;

x = -1 and y = 2

2 = $\frac{1}{5}$ x (-1) + c

c = 2 + $\frac{1}{5}$ = $\frac{11}{5}$

The equation of the new line is;

y = $\frac{1}{5}$ x + $\frac{11}{5}$

or multiply through by 5;

5y = x + 11

What is the domain of the function y=2√x-6? 88AX<∞ O 0≤x<∞ 3≤x<∞ 6≤x<∞

Travka [436]

Answer:

If the x-6 is all under the sqrt, the last answer is right:

6<= x <= infinity

If only x is under the sqrt and - 6 is NOT under the sqrt, then:

0 <= x <= infinity is the correct answer.

Step-by-step explanation:

You can look at the equation and or graph to determine the domain of a function. The domain is all the x's that may go into the equation or all the x's on the graph of the function. Inside of a squareroot symbol the number inside there must be positive. While considering the equation, only x's that keep that inside positive can be used.

For sqrt(x-6), x has to be 6 or bigger.

For sqrt(x) - 6, x has to be 0 or bigger.
