You'd do x+x, y+(-y), and 8+4. You'll get 2x+0=12.
X=6 and y=2
Answer:
<h2>H = 60° </h2>
Step-by-step explanation:
To find angle H we use tan
tan ∅ = opposite / adjacent
From the question
The opposite is 2√21
The adjacent is 2√7
So that's
tan H = 2√21/ 2√7
H= tan-¹ 2√21/ 2√7
<h3>H = 60° </h3>
Hope this helps you
Okay, so the rate is 1 job / hours, so:
1/3 + 1/7 (This covers both their work rates) = 1/n (n represents the time it take for them to work together)
Get the LCD:
7/21+ 3/21 = 1/n
10/21 = 1/n
Cross multiply:
10n = 21
n = 2.1
It will take them 2.1 hours, or 2 hours and 6 minutes

Start by y-k=m(x-h)
m= 3
k=2
h=1
so y-2=3(x-1)
distribute
y=3x-3+2
final answer: y=3x-1
