Answer:

all numbers

Step-by-step explanation:

3x - 5(x + 6) = -2x -2(5 + 10)

Distribute on both sides.

3x - 5x - 30 = -2x - 10 - 20

Add 2x to both sides.

-2x - 30 = -2x - 30

-30 = -30

Since we get a true statement after only doing legal steps to solve the equation, the equation has an infinite number of solutions.

Answer: all numbers

A government agency hires you to provide consulting on new rules regarding vehicle license plates. The agency is considering an

morpeh [17]

Answer:

There are 151,200 possible license plates.

Step-by-step explanation:

The order in which the digits are positioned is important(for example, 012345 is a different plate than 102345). No repeat digits are allowed, which means that we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

In this question:

There are 10 possible digits(from 0 to 9).

The plate has 6 slots.

$P_{(10,6)} = \frac{10!}{(10-6)!} = 151200$

There are 151,200 possible license plates.

Find the slope of the line that passes through (9,1) (5,8)

olganol [36]

Answer:

<h3>The slope = - 7/4</h3>

Step-by-step explanation:

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points (9, 1) and (5, 8). Substitute:

$m=\dfrac{8-1}{5-9}=\dfrac{7}{-4}=-\dfrac{7}{4}$

What is the solution to this system of equations?<br><br> x − 2y = 15<br> 2x + 4y = -18

S_A_V [24]

Use the subtraction method.
2 (x - 2y = 15) multiply top equation by 2 so we can subtract

2x - 4y = 30
2x + 4y = -18 (subtracted, we get 4x = 12...divide by 4...x = 3)

place the value for X into an original equation and solve for Y.

2(3) + 4y = -18
6 + 4y = -18
-6 -6
4y = -24 (divide by 4)

y = -6 Solution......(3, -6)
