Answer:

A

Step-by-step explanation:

The n th term ( explicit formula) for a geometric sequence is

f(n) = a(r)^{n-1}

where a is the first term and r the common ratio

Here a = 2 and r = - 8 ÷ 2 = - 4, thus

f(n) = 2(-4)^{n-1}

Seven hundred new chairs were delivered to a school. If each class
Natalija [7]

Answer:

24 chairs in each class needed

25 classrooms

700 chairs total

how many extra chairs

chairs will be c

t is total

t= 25×c

opposite of multiplication is division( 25 is multiplying by c) c needs to be alone

25 classrooms times chairs equal total chairs

t is 700

700=25×c

700/25=25/25c

700/25=C

c is 28

so 28 chairs for 25 classrooms

they need 24 chairs per class

so there are 4 extra chairs per class

4×25 is 100

**or just multiply 25 classes and 24 chairs

25 times 24 is 600

there are 700 chairs

100 left over

so 100 extra chairs

3x - 5y = 14 and – 2x + 2y = 0
zubka84 [21]

Answer:

x=5.6

y=-5.6

Step-by-step explanation:

3x - 5y = 14 Equation 1

– 2x + 2y = 0 Equation 2

Simultaneous equation can be solved either through elimination method or substitution method. But we use elimination method for this question

Multiply equation 1 by -2 (the coefficient of x in equation 2) and multiply equation 2 with 3 (the coefficient of x in equation 1), so that x will have the same coefficient in the new equations, and easy to eliminate

-2(3x - 5y = 14)

-6x+10y=-28 Equation 3

3(– 2x + 2y = 0)

-6x+6y=0 Equation 4

Subtract equation 4 from 3 to eliminate x

-6x+10y=-28

-6x+6y=0

-6x-(-6x)=-6x+6x=0

10y-6y=5y

-28-0=-28

5y=-28

y=-28/5

y=-5.6

Substitute for y in equation 2

– 2x + 2y = 0

– 2x + 2(-5.6) = 0

-2x-11.2=0

-2x=11.2

x=-11.2/2

x=5.6
