If x is the hypotenuse then
hyp^2 = 4^2 + 5^2
hyp^2 = 41
hypotenuse =
<span>
<span>
<span>
6.403124
</span></span></span>
if x is a leg then
leg^2 = 5^2 - 4^2
leg^2 = 25 - 16
leg^2 = 9
leg =3
A straight line is 180° and this is less than that but it’s more than 90°, 105° is close to 90 and this is a bit bigger so your best estimate is
B.) 180°
Y=mx+b is slope intercept form...
m=slope
b=y-intercept
Answer- y=-9+5
The last step of an equation whose solutions are x=-10 and x=-5 is:
(x+10)(x+5)=0
We need to add some previous steps, which make the equation an absolute value equation.
A way to do this, is writing |(x+10)(x+5)|=0,
the only solutions are still x=-10 and x=-5
Answer: |(x+10)(x+5)|=0
Brian will get roughly $16.55.
For this situation you will want to use 0.15 as 15%, and multiply this by the total cost of the bill.
$110.31 x 0.15 = $16.55
