How do I find the value of x so the slope of a line through (x,5) and (4,2) is 1/3?

Mathematics

Slope=change in y/change in x
1/3 = 5-2/x-4 (or 2-5/4-x)
1/3 = 3/x-4
then cross multiply
1(x-4) = 3(3)
x-4=9
add 4 to both sides
x=13

If one of the 50 states is chosen at random, then a standard die is rolled, Find the probability of getting a state that starts
Black_prince [1.1K]

Answer:

The final answer is 2/15 or 0.133

Step-by-step explanation:

The US States that start with an "N" are:

  1. Nebraska
  2. Nevada
  3. New Hampshire
  4. New Jersey
  5. New Mexico
  6. New York
  7. North Carolina
  8. North Dakota

The probability of selecting a state that starts with an N is 8/50

The probability of rolling at least a two is 5/6.

If we multiply the two probabilities together, we get 2/15.

An article bought a television for 2500 dollars and sold for 2325dollars find a.loss b.loss%​
SpyIntel [72]

Answer:

Loss= $175

Loss %= 7%

Step-by-step explanation:

First of all, you find the difference between 2500 and 2325 which is 175, as his has decreased, it is a loss of $175

To find the percentage you do the difference over the original amount

So 175/2500 which will give you 0.07

0.07 x 100 will give you 7%

Please help, need asap

For the first option, since when x is going down (to the left) the function is going up, it's not approaching 0. For the second option, since when x is going up (to the right) it's going up, it's not approaching negative infinity (negative infinity is all the way down). For the third one, since when x is going down the y values are climbing, we can assume that the function's values go to positive infinity. For the last one, since when x=0 y=0, when x=0 the function does not go to infinity

I need help with pythagoras’ theorem
fomenos

Answer:

Pythagoras’ theorem  is a way to find a side or hypothesis when you have 2 sides.  

The formula is:  a^2 + b^2 = c^2

a and b are sides

c is the hypothesis

<u>Ex:  A triangle has a leg that is 5 inches and a leg that is 7 inches.  Find the hypothesis using Pythagoras' theorem.  </u>

A leg is another way of saying a side.

5^2 + 7^2 = c^2

25 + 49 = x^2

sqrt(74) = sqrt(x^2)

sqrt(74) inches = hypothesis

<u>Ex:  A triangle has a leg that is 9 feet and a hypothesis that is 25 feet.  Find the other leg using Pythagoras' theorem. </u>

9^2 + b^2 = 25^2

81 + b^2 - 81 = 625 - 81

sqrt(b^2) = sqrt(544)

b = sqrt(554)

Do you understand more?
