9. Find the coordinates of point C along line segment AE with A(-2,-4) and

Nana76 [90]

Answer:

$C = (4,-1)$

Step-by-step explanation:

Given

$A = (-2,-4)$

$E = (8,1)$

$AC:CE = 3:2$

Required

Determine the coordinates of C

This is calculated as follows;

$C = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})$

Where:

$(x_1,y_1) = (-2,-4)$

$(x_2,y_2) = (8,1)$

$m:n = 3:2$

So, we have:

$C = (\frac{3 * 8 + 2 * -2}{3+2},\frac{3 * 1 + 2 * -4}{3+2})$

$C = (\frac{24 -4}{5},\frac{3-8}{5})$

$C = (\frac{20}{5},\frac{-5}{5})$

$C = (4,-1)$

Walt and Hank collect quarters from different states. Walt collected q quarters. Hank collected four fewer quarters than Walt. T

SpyIntel [72]

Answer:

Walt has 37 quarters. Hank has 33.

Step-by-step explanation:

Solve the given equation for q:

0.25q + 0.25q - 1.00 = 17.50

Simplify this, obtaining:

0.50q = 18.50

Simplifying this by multiplying both terms of this result by 100:

50 q = 1850

Thus, q = 1850/50 = 37

Walt has 37 quarters. Hank has 33.

Note that 37 + 33 = 70, and that 70($0.25) = $17.50. So our results are correct.
