Multiplying fractions by whole numbers:
1. You have to convert the whole number into an improper fraction.
2. You then multiply the fractions straight across.
Ex: 2/3 × 6 =2/3 × 6/1 = 2×6/3×1= 12/3= 4

11/26 chance that the student plays both instruments.

First, add the amount of students that just play flute or piano:

3 + 5 = 8

Then add 8 to the amount that does not play either instrument:

8 + 7 = 15

Then do:

26 - 15 = 11

Then place 11 over the amount of people:

11/26

Find the value of f(-3) and g(3) if f(x) = -6x + 3 and g(x) = 3x + 21r.
tekilochka [14]

Answer:

Part 1) f(-3)=21

Part 2) g(3)=9+21r

Step-by-step explanation:

Part 1) Find the value of f(-3)

we have

f(x)=-6x+3

we know that

f(-3) is the value of the function f(x) for x=-3

so

substitute the value of x=-3 in the function to find f(-3)

f(-3)=-6(-3)+3

f(-3)=18+3

f(-3)=21

Part 2) Find the value of g(3)

we have

g(x)=3x+21r

we know that

g(3) is the value of the function g(x) for x=3

so

substitute the value of x=3 in the function to find g(3)

g(3)=3(3)+21r

g(3)=9+21r

<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>1</u><u> </u><u>:</u>

replace x and y by their value 1 and 3

3 = 4(1) - 1 = 4-1 = 3

2(1) + 3 = 2 + 3 = 5

correct

<u>M</u><u>e</u><u>t</u><u>h</u><u>o</u><u>d</u><u> </u><u>2</u><u> </u><u>:</u>

y = 4x - 1

2x + y = 5

y = 4x - 1

y = -2x + 5

y - y = 4x - 1 - ( -2x + 5 )

0 = 4x - 1 + 2x - 5

6x - 6 = 0

6x = 6

x = 6/6 = 1

y = 4x - 1

y = 4(1) - 1

y = 3

correct
