Write an equation of the line in slope intercept form that pass through the two

Ber [7]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ -2}}\quad ,&{{ 15}})\quad 
% (c,d)
&({{ 9}}\quad ,&{{ -18}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-18-15}{9-(-2)}\implies \cfrac{-18-15}{9+2}
\\\\\\
\cfrac{-33}{11}\implies -3$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-15=-3[x-(-2)]
\\\\\\
y-15=-3(x+2)\implies y-15=-3x-6\implies y=-3x+9$

Use the quadratic formula to solve the equation if necessary round to the nearest hundredth

densk [106]

-5y^2 + 2y + 2 = 0

y = -2 ± ✓4 - 4*-5*2. /. -10

y = -2 ± ✓44. / -10

y = -1 ± ✓11. / -5

(-1+✓11)/-5. and (-1-✓11)/-5

A garden is in the shape of a square with a perimeter of

ElenaW [278]

The perimeter of a square is the sum of its sides and they are all equal, so to obtain the length of each of them we divide the perimeter of the first fence between 4:

P1= 64 feet/4 sides

P1= 16 feet

Then, the length of each side of the second fence will increase 2 feet at each end, as shown in the figure. We have then that the perimeter of the second fence is:

P2 = 20 feet x 4 sides

P2 = 80 feet

The sum of the perimeters of both fences is:

PT = P1 + P2

PT = 64 feet + 80 feet

PT = 144 feet

Total cost = 1.17 $ x 144 feet

Total cost = 168.48 $

The total cost of the fences was $ 168.48

a 96 ounce container of orange juice costs $4.80. at what price should a 128 ounce container be sold in order for the unit rate

Hunter-Best [27]

4.8 / 96 = x / 120
96x = 576
x = 576/96
x = 6

check :
unit rate for 96 oz container at 4.80 = 4.80/96 = 0.05 per oz
unit rate for 120 oz container at 6.00 = 6.00/120 = 0.05 per oz

Basically ur looking for an equivalent fraction (and that is what proportions are...this will reduce to the same unit rate. So ur answer is $ 6.00
