Input in standard form the equation of the given line. The line that passes through (-3, 5) and (-2, -6)

Answers

Answer:

The equation in standard form is 11x + y = -28.

Step-by-step explanation:

Let's start with y = mx + b

5 = -3m + b

-6 = -2m + b

Let's take the second less the first.

m = -11

Plug back in the first equation to calculate b.

5 = 33 + b

b = -28

So y = -11x - 28

11x + y = -28

23) It takes a bus 6 hours to take a trip. The train takes only 4 hours to make the same trip. The train travels

at a rate of speed that is 25 mph more than the speed of the bus. What is the rate of the bus and the rate of

the train? State what x represents, state the equation, and then state the answer.

Rate Time Distance

Bus x 6 бах

Train x-? 2(x+3)

Distance bus travels – Distance train travels

Answers

Answer:

x  = 50 mph        speed of the bus

y  = 75  mph       speed of the train

Step-by-step explanation:

Lt´s call  "x" speed of bus   and  "y" speed of train.

According to the problem statement

6*x  =  4*y                   (1)

y  =  x  + 25                 (2)

We solve for x and y the two equation system

y = ( 6/4)*x

( 6/4)*x  =  x  +  25

6*x = 4*x + 100

2*x  = 100

x  = 50 mph

And

y  =  (6/4)*x

y  = 300/4

y  = 75 mh

a) Show that x² - 8x + 20 can be written in the form (x - a)² + a where a is an integer.
b) Hence explain how you know that x² - 8x + 20 is always positive.

I have worked out the first bit of the question and the answer is:
x²-8x+20
x²-8x+16-16+20
(x-4)²+4
(x-a)²+a
a= 4

Answers

b) x^2 - 8x + 20 is always positive because in part a, you figured out that it could also be written as (x-4)^2 + 4.
You know that (x-4)^2 is greater than or equal to 0 so by adding 4, the result will always be positive.

Step-by-step explanation:

The number of ways in which the word 'PHILOSOPHY' can be arranged is 453,600.

What is a factorial?

The product of a whole number 'n' with every whole number until 1 is called the factorial. The factorial of 4 is, for example, 43221, which equals 24.

As we can see that the word 'PHILOSOPHY' has 10 letters therefore, the letters of the word can be arranged in the 10! manner, but it contains the letter P, H and O twice therefore, there will be words that will look the same and are counted twice. Thus, the number of ways the word PHILOSOPHY can be arranged are,

[tex]\text{Number of ways} = \dfrac{10!}{2! \times 2! \times 2!} = 453,600[/tex]

Hence, the number of ways in which the word 'PHILOSOPHY' can be arranged is 453,600.

In a group of 50 children, 11 cannot swim. What percentage can swim?

Answers

Answer:

78% of the children can swim

Step-by-step explanation:

There are 50 children, 11 of them cannot swim. The fraction of children that cannot swim is 11/50. We have to change that into a percentage.

11/50 x 2 will equal our percentage

11 x 2 = 22

50 x 2 = 100

22/100 or 22%

We have the percentage of the children who cannot swim, now we have to find the percentage of children who can swim.

100% - 22% = 78%
