Solve first equation for y:
5x+y=10
y=10-5x. Plug this equation into second equation
-x-(10-5x)=-2
-x-10+5x=-2
4x=8
x=2 (plug x into first equation)
5(2)+y=10
y=0
Answer:
Step-by-step explanation:
<u>This is an AP with:</u>
- The first term a₁ = 12
- Common difference d = 3
- Number of terms n = 40
<u>Number of the seats:</u>
- Sₙ = 1/2*n(a₁ + aₙ) = 1/2n(2a₁ + (n - 1)d)
- S₄₀ = 1/2*40(12*2 + 39*3) = 2820 seats
<u>Formula of nth term:</u>
- aₙ = a₁ + (n - 1)d
- aₙ = 12 + (n - 1)*3 = 12 + 3n - 3 = 3n + 9
- aₙ = 3n + 9
Answer:
a) below
b) log_35 (8) = x
c) x = 0.58487
Step-by-step explanation:
a) 35^x=8
<em>apply the exponent rule</em>
xln(35) = ln(8) → x = ln(8)/ln(35) → x = 3ln(2)/ln(35)
x = 0.58487
c) log_35 (8) = x
x = log_35 (8)
<em>base form (Rewrite 8 in power)</em>
x = log_35 (2^3)
<em>log rule: log_a(x^b) = b*log_a(x)</em>
log_35 (2^3) = 3log_35(2)
x = 3log_35(2)
x = 0.58487
