Answer:

y=2/5x - 1

Step-by-step explanation:

(0,-1) (-5,-3)

-3-(-1) over -5-0 = 2/5 2/5 = m

y=mx+b

-3 = 2/5 times -5 +b

-3 = -2 + b

+2 +2

-1 = b

y=2/5x 1

How many 5-letter words can be made using exactly 5 of the letters from

kow [346]

The total number of ways by words are formed is 35 ways.

According to the statement

We have given that the 5 letters and we have to make word from them and the letters are repeated as equal to letters in given words.

And we have to find the possible ways.

So, The given words are:

TEXAS and MEXICO

Here X = 2 and E = 2 and all other words are one time used words.

We can find possible ways by use of combination and permutation.

So,

Total number of ways = $3C_{1} ^{5} + 2C_{2} ^{5}$

here 3 because three letters are not repeatable and 2 letters are repeated for 2 times.

So,

Total number of ways = $3C_{1} ^{5} + 2C_{2} ^{5}$

Total number of ways = $3(\frac{5!}{1!} ) + 2(\frac{5!}{2!*3!} )$

Total number of ways = $3(5) + 2(10)$

Total number of ways = 15 + 20

Total number of ways = 35.

So, The total number of ways by letters are formed is 35 ways.

Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building materials and how the stren

Slav-nsk [51]

The logarithmic model for the length when the strength is of 8 Pascals is given by:

$f^{-1}(8) = \log_{2}{8} = \log_2{2^3} = 3$
That is, the length is of 3 units.

<h3>What is the function?</h3>

The strength in Pascals for a building of length x is given by:

$f(x) = 2^x$

To find the length given the strength, we apply the inverse function, that is:

$2^y = x$

$\log_{2}{2^y} = \log_2{x}$

$y = \log_2{x}$

Hence, when the strength is of 8 Pascals, $x = 8$ , and the length is given by:

$f^{-1}(8) = \log_{2}{8} = \log_2{2^3} = 3$

Find the measures of the interior angles of the triangle.

jeka94

Answer:

∠A = 30°

∠B = 60°

∠C= 90°

Step-by-step explanation:

This is a right triangle, you can see it mainly by the red square in C, and it is always used to mark 90 degrees.

Knowing that, you now know ∠C is 90°

Now, to find ∠B, you should use the following equation:

A+B+C = 180°

This means that the sum of the three angles of a triangle gives 180. ALWAYS. So to find the missing angle, ∠B, do the following:

Fill the values of the equation with the angles you now know:

30° + B + 90° = 180

Solve the equation, passing the 30° and 90° to the other side of the equal sing with Inverse Operation:

B = 180° - 30° - 90°

B = 60

Hope it helps!!

2 + 2 - 1 I really need help

shutvik [7]

Answer:

Step-by-step explanation:

Break the problem up into two

Ignore the -1 for now

2+2=4 because if you separate 2 and 2, you get four ones, therefore it's four

Now that you have four, subtract 1

And you got 3
