Answer:
C. 9
Step-by-step explanation:
3n - 18 = 9
3n (- 18 + 18) = 9 + 18
3n = 27
3n/3 = 27/3
n = 9
Answer:
Step-by-step explanation:
x - 10 = 0
x = 10
f(10) = 2*10² + 5 = 2*100 + 5 = 200 + 5
= 205
Remainder = 205
Answer:
The answer is
<h2>12.3 cm</h2>
Step-by-step explanation:
Since the triangle is a right angled triangle we can use trigonometric ratios to find y
To find y we use cosine
cos∅ = adjacent / hypotenuse
From the question
y is the adjacent
The hypotenuse is 15
So we have
![\cos(35) = \frac{y}{15} \\ y = 15 \cos( 35 ) \\ y = 12.28728](https://tex.z-dn.net/?f=%20%5Ccos%2835%29%20%20%3D%20%20%5Cfrac%7By%7D%7B15%7D%20%20%5C%5C%20y%20%3D%2015%20%5Ccos%28%2035%20%29%20%20%5C%5C%20y%20%3D%2012.28728)
We have the final answer as
<h3>12.3 cm to the nearest tenth</h3>

Answer:
4x + y = k
Step-by-step explanation:
=> 4y = x + 8
=> x - 4y = -8
Slope = 1/4
The other line's slope = -4
4x + y = k is the answer.
