\\ \sf\Rrightarrow y-1=\dfrac{2}{3}(x+1)

\\ \sf\Rrightarrow -3-1=\dfrac{2}{3}(a+1)

\\ \sf\Rrightarrow -4=\dfrac{-2(a+1)}{3}

\\ \sf\Rrightarrow -2(a+1)=-4(3)

\\ \sf\Rrightarrow -2(a+1)=-12

\\ \sf\Rrightarrow a+1=\dfrac{-12}{-2}

\\ \sf\Rrightarrow a+1=6

\\ \sf\Rrightarrow a=6-1

\\ \sf\Rrightarrow a=5

bija089 [108]

Answer:

franchise fast-food restaurant located in the Northeast specializing in halfpound hamburgers, fish sandwiches, and chicken sandwiches. Soft drinks and French fries are

also available. The planning department of Bun-and-Run Inc. reports that the distribution of

daily sales for restaurants follows the normal distribution and that the population standard

deviation is $3,000. A sample of 40 showed the mean daily sales to be $20,000. Find the 95%

confidence interval for the population mean.

how do you find the length of the hypotenuse when you have only the length of the altitude of the hypotensuse and a length of a
mrs_skeptik [129]

Answer:

By using The Pythagorean Theorem:

/Hypotenuse/^{2} = /Length of altitude/^{2} + /Length of leg/^{2} \

/Hypotenuse/ = \sqrt\ /Length of altitude/^{2} + /Length of leg/^{2} \}

Step-by-step explanation:

The Pythagorean theorem states that: Given a Right-angled triangle, the square of the hypotenuse equals the sum of squares of the other two sides ( Here, being the length of the altitude and length of leg). That is,

/Hypotenuse/^{2} = /Length of altitude/^{2} + /Length of leg/^{2} \ and hence,

/Hypotenuse/ = \sqrt\ /Length of altitude/^{2} + /Length of leg/^{2} \}

For example, If the length of the altitude is 4m and the length of leg is 3m. Using The Pythagorean theorem, the length of the hypotenuse will be

/Hypotenuse/^{2} = /Length of altitude/^{2} + /Length of leg/^{2} \\\/Hypotenuse/ = \sqrt{/Length of altitude/^{2} + /Length of leg/^{2}} \\/Hypotenuse/ = \sqrt{4^{2} + 3^{2}  }

/Hypotenuse/ = \sqrt{16+9} \\/Hypotenuse/ = \sqrt{25} \\/Hypotenuse/ = 5m

The length of the hypotenuse for the given example will be 5m.

This is how to find the length of an hypotenuse.

Use a related multiplication equation to show why the equation 5/n = 0 has no solution
Aleks04 [339]
Multiply both sides by 5:

5/n = 0

then

5/n * n = 0 * n

5 = 0 * n

This cannot be true because there is no number n you can multiply by 0 and get 5.
