False, because a^2+b^2=c^2 and no matter what numbers substitute for which ever variable the answer isn’t going to be true

A, B, and C are collinear, and B is between A and C. The ratio of AB to BC is 1:4.

schepotkina [342]

Let point C has coordinates $(x_C,y_C).$ Consider vectors

$\overrightarrow{AB}=(x_B-x_A,y_B-y_A)=(8-9,6-9)=(-1,-3),\\ \\\overrightarrow{BC}=(x_C-x_B,y_C-y_B)=(x_C-8,y_C-6).$

Since the ratio AB to BC is 1:4, you have that

$\dfrac{-1}{x_C-8}=\dfrac{1}{4}\quad \text{and}\quad \dfrac{-3}{y_C-6}=\dfrac{1}{4}.$

Find $x_C$ and $y_C:$

$x_C-8=-4,\\ \\x_C=-4+8=4,\\ \\y_C-6=-3\cdot 4=-12,\\ \\y_C=-12+6=-6.$

The cost per purse is $17 each to make, and she sells them for $35 each. This Saturday, she is renting a booth at a craft fair f

klasskru [66]

T = Total income

N = Number of purses

35N = the selling price of each purse

17N = Cost of each purse

T = 35*N - 17*N - 75

T = 18N - 75

If she wants here total income to be 350 dollars, it will take

T = 350 ; N = unknown.

350 = 18N - 75 Add 75 to both sides.

350 + 75 = 18N

425 = 18N

Rounded N = 24 <<<< Answer. The actually number is 23.611 but you can't sell 0.611 of a purse.
