ratelena [41]

Answer:

I believe your answer is C 94.79

If this answer is wrong please let me know my apologies

Step-by-step explanation:

If my math is correct

44.50+44.50=89

89

Now, find the tax value by multiplying tax rate by the before tax price:

tax = 85 × 0.065

tax = 5.53 (tax value rounded to 2 decimals)

Add tax to the before tax price to get the final price:

The final price including tax = 85 + 5.53 = 90.53

90.53 plus the shipping 3.89=94.79

Find the following equation
adoni [48]

Answer:

y=\frac{-1}{2}x+7

Step-by-step explanation:

Slope intercept form: y=mx+b when m is the slope of the line and b is the y-intercept (the y-coordinate of the point the line crosses the y-axis)

<u>1) Find the slope (</u>m<u>)</u>

m=\frac{y_2-y_1}{x_2-x_1} when the points are (x_1,y_1) and (x_2,y_2)

We can use any two points that the table gives us to plug into this equation. For example, we can use the points (14,0) and (0,7):

m=\frac{0-7}{14-0}\\m=\frac{-7}{14}

Simplify the fraction

m=\frac{-1}{2}

So far, our equation looks like this:

y=\frac{-1}{2}x+b

<u>2) Find the y-intercept (</u>b<u>)</u>

The y-intercept is the y-coordinate of the point the line crosses the y-axis, or in other words, it's the value of y when x is equal to 0.

Looking at the table, we can see that y is equal to 7 when x is equal to 0, so, therefore, b=7.

Now, this is our final equation after plugging in m and b:

y=\frac{-1}{2}x+7

I hope this helps!

Angle B measures 60°. What is the measure of the angle that is complementary to angle B?
vodomira [7]
Complementary angles add up to 90.
Say the complementary angle is A. 
Angle A + Angle B = 90
Angle A + 60 = 90
Angle A = 30 degrees

Hope this helps :)
