$17.49 because you multiply 22 by .25 getting 5.5. You subtract that from the original 22 getting 16.5 which you then multiply by the sales tax .06. Add the tax amount to the 16.5 to get 17.49.
Step-by-step explanation:
domain(6,3,9,5,8)
range(2,5,0,7,1)
The equation of the line in slope-intercept form is given by
step 1
Find out the slope m
we have the points (-6,5) and (2,1)
step 2
Find out the equation of the line
we have
m=-1/2
point (2,1)
substitute and solve for b
therefore
The equation of the line is
Problem N 2
Write the equation of the line in the point-slope form that passes through the point (-2,3) and has a slope of 1/2
The equation of the line in point-slope form is given by
we have
m=1/2
point (-2,3)
substitute
The answer to the question is 229
<span>The table to represent a linear function with a rate of change of +5
</span>
so, m = 13 + 5 = 18
The correct answer is option 3 ⇒ <span>m = 18

========================================
another solution :
The table represents a linear function
the general equation of the linear function is ⇒ y = ax+b
where a is the slope and b is constant
By using the first and the third points from table to find the equation of the linear function
at x = 3 ⇒ y = 13 and at x = 5 ⇒ y = 23
∴ 13 = 3a+b → (1)
23 = 5a+b → (2)
solve (1) and (2) to find a and b
So, a = 5 and b = -2
∴ y = 5x - 2
After that by substitution with x = 4 int the equation of y
∴ y = 5*4-2 = 18
∴ m = 18
