Answer:
<em>The washing machine cost $600 before tax</em>
Step-by-step explanation:
<u>Percentages
</u>
The washing machine cost $651 including a tax of 8.5%.
If x was the cost of the washing machine before tax, then the tax was:
x*8.5/100 = 0.085x
It was added to the original price:
x + 0.085x = 1.085x
That is the final price, thus
1.085x=$651
Solving:
x = $651/1.085
x = $600
The washing machine cost $600 before tax
Use quadratic formula
8= 4 +17t -16t^2
16t^2 - 17 t + 4
answers (17 + square root (33)) /32 and (17 - square root (33)) /32
The slope-intercept form:

m - slope
b - y-intercept → (0, b)
We have the points (-4, -6) and (2, 6). Substitute:

Put the coordinates of the point (2, 6) to the equation of a line:

<h3>Answer: y = 2x + 2</h3>
Answer:
Yes, because there are 9 grid squares on one side, 16 grid squares on the other side, and 25 grid squares on the hypotenuse, and 9 + 16 = 25.
