What is an equation of the line that passes through the point (-6, -7) and is
Alexandra [31]

Answer:

Step-by-step explanation:

Product of slope of perpendicular lines = -1

6x + 5y = 30

Write this equation in y = mx + b  form

        5y = -6x + 30

          y = \frac{-6}{5}x+\frac{30}{5}

          y=\frac{-6}{5}x + 6

Slope of this line m₁ = -6/5

m₁ * m₂ = -1

      m₂ = -1÷m₁ = -1 * \frac{5}{-6}  

m_{2}=\frac{5}{6}     & (-6 , -7)

Equation of the required line: y - y₁ = m (x - x₁)

y - (-7) = \frac{5}{6}(x - [-6])\\\\y + 7 = \frac{5}{6}x + 6 *\frac{5}{6}\\\\y = \frac{5}{6}x +5-7\\\\y=\frac{5}{6}x-2

mark has 160 yards of fencing to enclose a rectangular garden whose length is to be four times its width what will be the dimens
vredina [299]

perimeter = 2W+2L

Length = 4W

160 = 2W +2(4W)

160 = 10W

w = 160/10 = 16 yards

length = 16*4 = 64 yards


Check:

64*2 = 128, 16*2 = 32

128+32 = 160

Length = 64 yards, Width = 16 yards

Belle sells cosmetics at a local store. She earns $12.00 for every hour she works she also earns 5% commission on all sales that
victus00 [196]
A. Because Belle worked for 35hrs and she earns $12 per hour, which makes $420. Then Belle sold 2550 in cosmetics and 5% in decimals equals 0.05. Multiply 2550 by 0.05 and you get $127.50, that is the 5% commission for the 2550 Belle sold. Lastly add the $420 and $127.50 and you get $547.50 which is answer A.
