Answer
x = 21
HOS = 68
Explanation
The arrows beside x point to 12 and 6, which is a straight angle. Straight angles always add up to 180 degrees.
So that means 3x+5 plus 5x+7 must equal 180 degrees.
3x+5+5x+7 = 180
Combine like terms.
8x+12 = 180
Subtract 12 from both sides.
8x = 168
x = 21
But BE CAREFUL.
The problem is asking for the angle HOS.
To do this, just substitute what you got for x into the expression.
3(21)+5 = 68
The value of HOS is 68 degrees.
17/tan75 that is the answer
Answer:
Step-by-step explanation:
4 is a quarter of 16, what is 25% of 16.
27% is a bit over 25%, so is 4.32 over 4.
We are given
where
y is the cost in dollars
x is distance in dollars
now, we can find derivative
so,
So,
the rate of change of the cost in dollars with respect to the number of miles is 1.5.........Answer
Find x and y intercept and plot
set x to zero and find y
set y to zero and find x
tada, 2 points
if x=0, then y=-4
if y=0, then x=-16
we havee the points
(0,-4) and (-16,0)
or
y=-1/4x-4
