Answer:

x = 3Sides are 6, 8 and 10

Step-by-step explanation:

Use Pythagorean to find the value of x:

c² = a² + b²

Consider:

a = x + 3, b = 3x - 1, c = 4x - 2

Substitute and solve for x:

(4x - 2)²  = (x + 3)² + (3x - 1)²16x² - 16x + 4 = x² + 6x + 9 + 9x² - 6x + 116x² - 10x² - 16x + 4 - 10 = 06x² - 16x - 6 = 03x² - 8x - 3 = 03x² - 9x + x - 3 = 03x(x - 3) + (x - 3) = 0(x - 3)(3x + 1) = 0x - 3 = 0, 3x + 1 = 0x = 3, x = - 1/3

Positive root is accepted only.

Sides of the triangle:

a = x + 3 = 3 + 3 = 6b = 3x - 1 = 3*3 - 1 = 8c = 4x - 2 = 4*3 - 2 = 10

what is the slop of the line that passes through the points (-2,3) and (-14,-5)? write your answer in simplest form.

Answers

Answer:

2 / 3

Step-by-step explanation:

( x1, y1 ) = ( - 2, 3 )

Here,

x1 = - 2

y1 = 3

( x2, y2 ) = ( - 14, - 5 )

Here,

x2 = - 14

y2 = - 5

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope = ( - 5 - 3 ) / ( - 14 - ( - 2 ) )

          = - 8 / ( - 14 + 2 )

          = - 8 / - 12

Slope = 2 / 3

what would the answer be for:

2 −5−24.

with full steps.

Answers

The answer would be -27. Because if you subtract 2 then 5 from that would give you -3 and then subtract 24 it would be -27

An advertising agency increased their fees to an $80 setup fee plus $4 for every advertisement. Write a rule for the new fee. Write ordered pairs for the fees for 10, 20, 30, and 40 advertisements.

please help !!!!

Answers

Answer:

b.

Step-by-step explanation:

As it says there is already a set up fee of $80 and it is $4 FOR EVERY advertisement, the equation would be y = 80 + 4x. Obviously, y should be greater than x since you are calculating the cost and not anything else, so b should be your answer. Even without logically guessing, the equation proves that b is correct.

Answers

Answer:

a) 1,144 rad/min

b) 182.1 rev/min

Step-by-step explanation:

d= 24 inches

radius = 24/2 or 12 inches

speed = 13mi/h

need to convert speed to inches/min

v = Θ * r

1 mile = 63360 inches, and 1 hour = 60 min

13 mi * (63360 in / mi)

= 823680 in /  (1 hr * 60 min / hr)

=13728 in/min

Now go back to the equation

13728  in / min = ω * 12 in

13728  /12 = Θ

1,144 rad/min

b) 1 revolution = 2π

w= Θ/2π

w= 1,144rad/ min/2pi rad

Step-by-step explanation:

First you need to reduce the fractions then you choose a common denominator to calculate:6/12=1/2 then you see the you see 1/4 can be a common denominator so you equal 1/2 to the denominator by 4, which means multiplying 2 by both the numerator and denominator, we get 2/4 after that you add and subtract in parentheses and you will get 1/4 then you multiply by 5 to get 5/4 the finally you have to plus 0,5 you will get 7/4 done.

Safe Combination. The author owns a safe in which he stores all of his great ideas for the
next edition of this book. The safe combination consists of four numbers between 0 and 99. If
another author breaks in and tries to steal these ideas, what is the probability that he or she will
get the correct combination on the first attempt? Assume that the numbers are randomly
selected. Given the number of possibilities, does it seem feasible to try opening the safe by
making random guesses for the combination?

Answers

Answer: 1/96059601

Don't break in

Step-by-step explanation:

First we need to find how many combinations there are.

We can find that by multiplying the four different number of options which in this case are all 99.

99 * 99 * 99 * 99

= 96059601

There are 96059601 different combinations and one correct combination.

So, the chance of them getting it is 1/96059601

It is definitely not a nice number so probably don't try and break in.

How do you do this math

Answers

Answer: y = -3x - 6

Step-by-step explanation:

One way to write a linear equation is with slope-intercept form.               Slope-intercept form is y = mx + b, where m is the slope, and b is the              y-intercept.

Thus, the equation is y = -3x - 6

Hope it helps :) and let me know if you are confused anywhere.

Answer:

y = -3x - 6

Step-by-step explanation:

Insert the information into the slope-intercept form equation:

y = mx + b

m = slopeb = y-intercept value

In this instance, the slope is -3 and the y-intercept value is -6. Therefore, the equation of the line is y = -3x - 6
