If the first term is n^2, then fisr make the equation =0, which would be n^2+7n+10. So what number multiplies to positive 10 and adds up to positive 7? 5 and 2. So factor the equation into (n+5)(n+2)=0. To make the equation 0, one of the parts have to be zero. The cases would be n=-5, -2

The supreme choice pizza at Pizza Paradise contains 22 different meats and 33 different vegetables. The customer can select any
mash [69]

Answer:

1680 possible pizzas

Step-by-step explanation:

Pizza contains 2 different meat and 3 different vegetables.

If there are 5 meats and 8 vegetables, the customer can select any one of 3 types of crust.

Total number of ways to select meat = 5C2

nCr = n! /(n-r)! r!

5C2 = 5! / (5-2)!2!

= 5! / 3!2!

= 10

Total number of ways to select vegetables = 8C3

= 8!/(8-3)!3!

= 8! / 5!3!

= 56

Total number of pizza choice that can be made = 3 * 5C2 * 8C3

= 3*10*56

= 1680 possible pizza

Write in slope-intercept form the equation of the line that is parallel to the line y=2/3x-6 and passes through the point (3,3)
ser-zykov [4K]

Answer: y=2/3x+1

Step-by-step explanation:

y=2/3x-6

y=2/3x+b ==> Parallel to y=2/3x-6 since they both have the same slope

3=2/3 (3)+b

3=2*3/3 +b

3=6/3 +b

3=2+b

b=1

y=2/3x+1

What is the slope of the line that passes through the points (-2, -3), and (5, 4)?
Karolina [17]
\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ -2}}\quad ,&{{ -3}})\quad 
%   (c,d)
&({{ 5}}\quad ,&{{ 4}})
\end{array}
\\\quad \\\\ % slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{4-(-3)}{5-(-2)}\implies \cfrac{4+3}{5+2}
