5x + 4y = 32 ⇒ 45x + 36y = 288
9x - 1y = 33 ⇒ <u>45x - 5y = 165</u>
<u>41y</u> = <u>123</u>
41 41
y = 3
5x + 4(3) = 32
5x + 12 = 32
<u> - 12 - 12</u>
<u>5x</u> = <u>20</u>
5 5
x = 4
(x, y) = (4, 3)
Answer:
a) m∠3=113°
b) x=8 (but check below)
Step-by-step explanation:
a) we know m∠1=m∠5
6x-5=5x+7
x=12
we also know m∠1+m∠3=180°
plug x into the formula for m∠1
m∠1=67
m∠1+m∠3=180°
67+m∠3=180°
m∠3=113°
b) Again, we know since those lines are parallel that m∠4=m∠8
x²-4x=32
x²-4x-32=0
(x-8)(x+4)=0
x=8 or x=-4
i think (not 100% sure about this part lol) but x cannot be negative so it's 8
again i'm not sure but it is either 8 or 8,-4.
Step-by-step explanation:
By Law of Indices, (a^m)^n = a^(mn).
Hence (h²)^(-3) = h^(-6) or 1/h⁶.
Answer:
If you're solving for F then F=1. If you're solving for x then there's no solution
