Substitute the variable for the value given.

11 - 3m becomes 11 - 3(2)

Now do the order of operations.

11 - 3(2) =
11 - 6 =
5

So, the answer is 5.

Which set of coordinates satisfies the system of equations y = x − 3 and y = -2x + 1?

Svetlanka [38]

Answer:

C

Step-by-step explanation:

The first equation has a y-intercept of -3. Only one line does.

The second equation has a y-intercept of +1. Only one line does.

The point of intersection of those two lines is the point labeled C. That has coordinates that satisfy both equations. (The point is on both lines.)

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 17 minute

Arturiano [62]

Answer:

P(X>5) = 0.857

Step-by-step explanation:

Let X $\sim$ uniform(3.17)

$f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17$

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

$P(X > 5) = \int ^{17}_{5} f(x) \ dx$

$P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx$

$P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}$

$P(X > 5) =\dfrac{1}{14} [17-5]$

$P(X > 5) =\dfrac{12}{14}$

P(X>5) = 0.857

PLEASE HELP!!!! Given the system of linear equations y= -5 and y= 3x-2 Part A: Graph the system of linear equations. Part B: Use

ahrayia [7]

Answer:

A. See attached diagram

B. (-1,-5)

C. (-1,-5)

Step-by-step explanation:

Part A. See attached diagram

Part B. The commmon point of two graphs is point (-1,-5), then the solution of the system of two equations is x=-1, y=-5.

Part C. Solve the system algebraically. Substitute y=-5 into the second equation:

$-5=3x-2,\\ \\-5+2=3x,\\ \\-3=3x,\\ \\x=-1.$

Then the solution of the system is x=-1 and y=-5.
