The equation of line is:
Further explanation:
Given equation of line is:
y = 3x+5
The standard form of point-slope form is:
y = mx+b
Comparing the given equation with the standard form is:
m = 3
We know that product of slopes of two perpendicular lines is -1
Let m2 be the slope of line perpendicular to y = 3x+5
Then
Putting the value of slope in standard form
To find the value of b, putting (-3,-4) in equation
Putting the values of slope and b in equation
Keywords: Slope, Point-intercept form

Eric bought a canoe for $333.75 and the sales tax was 5.25%.
If you are trying to calculate the sales tax amount, you just convert the percentage into a decimal, and then multiply it by the price.
5.25% = 0.0525
0.0525 * 333.75 = <span>17.521875
Therefore, the sales tax amount is approximately $17.52.
If you are trying to find the total price of Eric's purchase, you would just add the sales tax to the price of the canoe.
17.52 + 333.75 = $351.27
The total cost of Eric's purchase was approximately $351.27.

We know that
sin²x+cos²x=1
so
clear cos x
cos x=(+/-)√[1-sin²x]
in this problem
<span>Angle 0 is in quadrant 1 -----> cos o and sin o are positive
</span>sin o=2/5
cos x=√[1-(2/5)²]----> cos o=√[1-4/25]----> cos o=√[21/25]---> cos o=√21/5
the answer is
cos o=√21/5
Y varies directly with x m eans
y=kx where k is constant
y=40
x=16
find k
40=k16
divide both sides by 16
5/2=k
y=5/2x
y=-5 find x
-5=5/2x
times 2/5 both sides to cancle fraciton (5/2 times 2/5=10/10=1)
-10/5=x
-2=x
x=-2
