308 slices would be sold.
38*8= 304, plus 4 slices in half a pizza makes 308 slices.

First multiply the total amount of pizzas sold by the amount of slices in each pizza. ( It would also help if you converted the fraction into a decimal; 1/2=.5 )

38.5 * 8 = 308

A total of 308 slices of pizza were sold.

Use the following graph of the function f(x) = −3x4 − x3 + 3x2 + x + 3 to answer this question: What is the average rate of chan

Alinara [238K]

the average rate of change is just the slope from (0,f(0)) to (1,f(1))

find f(0) and f(1)

$f(0)=-3(0)^4-(0)^3+3(0)^2+0+3=3$

$f(1)=-3(1)^4-(1)^3+3(1)^2+1+3=-3-1+3+1+3=3$

slope from (0,3) to (1,3) is rise/run=(3-3)/(0-1)=0/-1

the average rate of change from x=0 to x=1 for f(x) is 0

the sum of three number is 202, the second is three more than the first number, the third number is three times the second numbe

sertanlavr [38]

Answer:

x = 38

y = 41

z = 123

Step-by-step explanation:

x + y + z = =202

y = x + 3

z = 3y = 3(x + 3) = 3x + 9

x + y + z = x + x + 3 + 3x + 9 = 5x + 12 = 202

5x + 12 = 202

5x = 190

x = 38

y = x + 3 = 41

z = 3y = 123

Simplify the expression. -2/3c -9/5 + 14c + 3/10

Andrew [12]

Answer:

$13 \frac{1}{3} c - 1 \frac{1}{2}$

Step-by-step explanation:

We want to combine alike terms so

-2/3c+14c & -9/5+3/10

14c-2/3

$\frac{14}{1} c - \frac{2}{3} c$

Multiply 14/1 by 3/3 to get the denominators the same

$\frac{42}{3} c - \frac{2}{3} c$

Subtract

$\frac{40}{3} c$

simplify

$13 \frac{1}{3} c$

now

$\frac{3}{10} - \frac{9}{5}$

Multiply 9/5 by 2/2

$\frac{3}{10} - \frac{ 18}{10}$

Subtract

$- \frac{15}{10}$

Simplify

$- 1 \frac{1}{2}$

put both together

$13 \frac{1}{3}c - 1 \frac{1}{2}$
