Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
First, we should figure out an equation and take note that we are dealing with complementary angles (angles that add up to 90 degrees)
Your equation:
(2x + 1) + (x - 7) = 90
Now solve!
====================================================================
SOLVING...
<span>(2x + 1) + (x - 7) = 90
</span>
Simplify and combine like terms
2x + 1 + x −7 = <span>90
</span><span><span>2x + 1 + x + </span>−7 </span>= <span>90
</span><span><span>(2x + x) </span>+ <span>(1 + −7) </span></span>= <span>90
</span><span>3x + −6 </span>= <span>90
</span>
Add 6 to each side
<span><span><span>3x </span>− 6 </span>+ 6 </span>= <span>90 + <span>6
</span></span>3x = 96
Divide each side by 3
3x ÷ 3 = 96 ÷ 3
x = 32
Answer:
c
Step-by-step explanation:
c is just an expression it doesnt have an inequality
Answer:
yes, it is a right triangle
Step-by-step explanation:
it follows the pythagorean theorem
if you were to plug in the numbers, it would work
a^2 + b^2 = c^2
6^2 + 8^2 = 10^2
36 + 64 = 100
hope this helps :)
It’s 1, 3x + 15 = 18
3x +15 - 15 = 18 - 15
3x=3
3/3 = 1
