Answer:
y=1/2x+13
Step-by-step explanation:
The slope-intercept form is: y=mx+b, where m is the slope and b is the y-intercept of the line. First, you have to calculate the slope using the following formula:
m=y2-y1/x2-x1
You have two points: (6, 16), (10,18) as the chores are the independent variable which is x, and the money is the dependent variable which is y.
Now, you can replace the values in the formula:
y2=18
y1=16
x2=10
x1=6
m=(18-16)/(10-6)
m=2/4
m=1/2
Now, you use the point-slope formula:
y-y1=m(x-x1)
You have to replace the value of the slope and one point and solve for y:
y-16=1/2(x-6)
y-16=1/2x-3
y=1/2x-3+16
y=1/2x+13
According to this, the answer is that the equation for his allowance in slope-intercept form is: y=1/2x+13.
You have to add the like terms in the equation
These like terms are 8q^2 and 7q^2 because they both share q^2
The other like terms are -5q and -8q because they both have ‘q’
So add them and then add extra numbers (the 10) to the equation

Answer:
$44.31
Step-by-step explanation:
Regular Price = $42
Sales Tax Rate = 5 1/2% or 5.5%
The total cost would be the regular price PLUS the sales tax. We find the sales tax by finding 42's 5.5%.
First, converting percentage to decimal (dividing by 100):
5.5% = 5.5/100 = 0.055
Now finding 5.5% of $42:
42 * 0.055 = $2.31
Now, the total price is the SUM of regular and this sales tax:
Total Price = 42 + 2.31 = $44.31
