Y = –8x + 8<br> y = –8x + 8
fiasKO [112]

Answer:

x=0

y=8

Step-by-step explanation:

This is a simultaneous equation

So let's solve

y=-8x+8..(1)

y=-8x+8...(2)

Add (1) and (2)

2y=16

Make y the subject of formula by dividing both sides by 2

y=8

Substitute the value for y into (2)

8=-8x+8

Collect like terms

8-8=-8x

0=-8x

Divide both sides by-8

x=0

Therefore x is 0 and y is 8

D(n)=5/16(2)^n-1<br><br> please help lol
Sedaia [141]

Answer:

In this maths tutorial, we introduce exponents / powers and roots using formulas, solved examples and practice questions.

Powers and Roots | Formulas, Solved Examples, Practice Problems

Exponents, also called powers, are a way of expressing a number multiplied by itself by a certain number of times.

When we write a number a, it is actually a1, said as a to the power 1.

a2 = a*a

a3 = a*a*a

:

:

an = a*a*a*a* . . . n times.

Basic formulas in Powers and Roots

Some basic formulas used to solve questions on exponents are:

(am)n = (an)m = amn

am.an = am+n

a-m = 1/am

am/an = am-n = 1/an-m

(ab)n = anbn

(a/b)n = an/bn

a0 = 1
