\mathfrak{apply~the~fraction~rule~:}~\frac{a}{c}~ -~\frac{b}{c} = \frac{a~-~b}{c}

= \frac{3-1}{8}

=\frac{2}{8}

\mathfrak{cancel~the~numbers~:}~\frac{2}{8} = \frac{1}{4}

=\frac{1}{4}

What is the equation of the line that passes through (4, -1) and (-2, 3)?
inessss [21]
(4,-1),(-2,3)
slope = (3 - (-1) / (-2 - 4) = -4/6 = -2/3

y = mx + b
slope(m) = -2/3
use either of ur points...(4,-1)...x = 4 and y = -1
now sub into the formula and find b, the y int
-1 = -2/3(4) + b
-1 = -8/3 + b
-1 + 8/3 = b
-3/3 + 8/3 = b
5/3 = b
so ur equation is : y = -2/3x + 5/3

Adrian purchases six tubes of paint and three paint brushes at a craft store each tube of paint cost $2.50 each paint brush cost
lesantik [10]

Answer:

The total amount of money pays by Adrian is $14.5 .

Step-by-step explanation:

As given

Adrian purchases six tubes of paint and three paint brushes at a craft store.

Each tube of paint cost $2.50 each paint brush cost $0.50 .

Total cost of the 6 tubes of paints and 3 paint brushes = 6 × Cost of each tube of paint + 3 × Cost of each paint brush cost .

Putting the values in the above

Total cost of the 6 tubes of paints and 3 paint brushes = 6 × 2.50 + 0.50 × 3

                                                                                           = 15 + 1.5

                                                                                           = $16.5

As given

Adrian has a coupon for $2 of his purchase .

Total amount money pay by Adrian = Total cost of the 6 tubes of paints and 3 paint brushes - Coupon cost

Putting the values in the above

                                                            = $16.5 - $2

                                                            = $ 14.5

Therefore the total amount of money pays by Adrian is $14.5 .
