Answer:
$37.86
Step-by-step explanation:
Multiply 29.99 by 0.0625 to get the sales tax
29.99x0.0625=1.87
Multiply 29.99 by 0.20 to get the tip
29.99x0.20=5.998
Round 5.998 to 6
Add 1.87 to 29.99
29.99+1.87=31.86
Add 6 to 31.86
31.86+6=37.86
Answer:
Step-by-step explanation:
The equation of a straight line can be represented in the slope intercept form as
y = mx + c
Where
m = slope = (change in the value of y in the y axis) / (change in the value of x in the x axis)
The equation of the given line is
x + 2y = 4
2y = - x + 4
y = -x/2 + 4/2
y = - x/2 + 2
Comparing with the slope intercept form, slope = - 1/2
If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the given line.
Therefore, the slope of the line passing through (- 2, 1) is 2
To determine the intercept, we would substitute m = 2, x = - 2 and y = 1 into y = mx + c. It becomes
1 = 2 × - 2 + c = - 4 + c
c = 1 + 4 = 5
The equation becomes
y = 2x + 5
If a line were to be perpendicular from said points, the slope of it would be -1/28. Hope this helps!
Answer:
x = 3
y = 8
Step-by-step explanation:
Since it gives you x, you need to plug in the number given for it into the equation:
y = 3x - 1
y = 3(3) - 1
y = 9 - 1
y = 8
So now you have, x = 3 and y = 8
