Answer:
-7/12
Step-by-step explanation:
-5-2 = -7 y
and
8- (-4)=12 x
Answer: No
Find the equation of the line using slope-intercept form: y = mx + b
y = -1/2x + b ^ ^
slope y-intercept
Find b, the y-intercept (where the line intersects the y-axis) by substituting the coordinates of point Q (6, 7).
y = -1/2x + b Subtitution
7 = -1/2(6) + b Simplify
7 = -3 + b Add 3 to both sides
10 = b Isolated b
b = 10 Isolated b
Using the above information, find the equation of the line.
y = -1/2x + b
y = -1/2x + 10
To find if point S (2,5) lies on the line, substitute in its coordinates in the equation of the line.
y = -1/2x + 10 Substitution
5 = -1/2(2) + 10 Simplify
5 = -1 + 10 Simplify
5 = 9 --> If the statement is true, the point lies on the line.
If the statement is false, the point does not lie on the line.
In this case, 5 does not equal 9. Therefore, point S does not lie on the line.
You must find LCM
because we should find a number same for both 3 and 4
Lcm of 3 and 4=12
Therefore the least number of kites she can make is 12
Answer:
40
Step-by-step explanation:
Cost of the spa treatment = $42
Percentage of sales tax = 6%
Percentage of tips = 20%
Normally the tips amount is calculated before adding sales tax.
Then
Amount of tips given = (20/100) * 42
= (1/5) * 42
= 8.40 dollars
Amount of sales tax taken = (6/100) * 42
= 252/100
= 2.52 dollars
Then
The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars
= 52.92 dollars
So we can see that $52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.
