Kayla wants to represent "18 divided by the sum of 3 and 3". She writes 8/(3x3) . Is Kayla's expression correct? Explain using c

Naya [18.7K]

no it is not correct. 18 divided by the sum of 3 and 3 equals 18 ÷ (3+3)

"sum of 3 and 3 " means 3+3 therefore 8/(3x3) = 8/9 and is completely different from the equation desired to be represented.

Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?

Eduardwww [97]

Step-by-step explanation:

Look at the picture.

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

$d=\sqrt{x^2+y^2}$

W(-3, 4)

$d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$

(3, -4)

$d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

(4, 3)

$d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, -3)

$d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, 3)

$d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

Find the slope of the line. Help?

nirvana33 [79]

Answer:

-1/2x

Step-by-step explanation:

We know point (-10, 0) and point (0,-5)

So, the slope would be -5/10 or simplified at -1/2

y= -1/2x

Y varies inversely with x if y = 7 when x =-4, find y when x = 5

marysya [2.9K]

Answer:

y = - $\frac{28}{5}$

Step-by-step explanation:

Given y varies inversely with x then the equation relating them is

y = $\frac{k}{x}$ ← k is the constant of variation

To find k use the condition y = 7 when x = - 4, then

7 = $\frac{k}{-4}$ ( multiply both sides by - 4 )

- 28 = k

y = $\frac{-28}{x}$ ← equation of variation

When x = 5 , then

y = $\frac{-28}{5}$ = - $\frac{28}{5}$
