20% of $30 = $6
30 - 6 = $24
10% of $24 = $2.40
24 - 2.40 = $21.60 cost of student lunch

You have to do each percent separate to get the cost.
If you just take 30% off from the original cost of $30 it will be the wrong answer.

What is the average rate of change over the interval [0, 4]?

choli [55]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Given:

Interval, [0, 4]

Required:

Average range of change over [0, 4]

SOLUTION:

Find f(0) and f(4) from the graph:

$f(0) = 0$ (when x = 0, y = 0)

$f(4) = 3$ (when x = 4, y = 3)

Average rate of change = $\frac{f(b) - f(a)}{b - a}$

Where,

$a = 0, f(a) = 0$

$b = 4, f(b) = 3$

Plug in the values into the formula for average rate of change.

$= \frac{3 - 0}{4 - 0}$

$= \frac{3}{4}$

Average rate of change $= \frac{3}{4}$

Can someone give the answer

KonstantinChe [14]

Answer:

(2, -2)

Step-by-step explanation:

Given the equation

x - y = 4 ... 1

6x+y = 10 ...2

Add both expressions

x+6x = 4 + 10

7x = 14

x = 14/7

x = 2

Substitute x = 2 into equation 1;

From 1;

x - y = 4

2 - y = 4

y = 2-4

y = -2

Hence the solution to the system of equation is (2, -2)
