Point P is located at (−2, 7), and point R is located at (1, 0). Find the y value for the point Q that is located two over three

otez555 [7]

Answer:

$y_Q=\dfrac{21}{5}=4.2$

Step-by-step explanation:

If the point Q that is located two over three the distance from point P to point R, then PQ:QR=2:3.

Use formula to find the coordinates of the point Q:

$x_Q=\dfrac{3x_P+2x_R}{3+2}\\ \\y_Q=\dfrac{3y_P+2y_R}{3+2}$

In your case, P(-2,7) and R(1,0), then

$x_Q=\dfrac{3\cdot (-2)+2\cdot 1}{3+2}=\dfrac{-4}{5}\\ \\y_Q=\dfrac{3\cdot 7+2\cdot 0}{3+2}=\dfrac{21}{5}$

If f(x) = 9x - 2 and g(x) = 2x², what is the value of f(4) - g(4)

pishuonlain [190]

9514 1404 393

Answer:

f(4) -g(4) = 2

Step-by-step explanation:

Fill in the given values for x and do the arithmetic.

f(4) = 9·4 -2 = 34

g(4) = 2·4^2 = 32

Then ...

slega [8]

It is definitely C: 20%

Subtract the original value from the new value, then divide the result by the original value then multiply the result by 100 and it will give you the answer

$\frac{4200 - 3500}{3500} \times 100$
$\frac{700}{3500} \times 100$
$0.2 \times 100 = 20\%$
