Equation of the given line will be :
now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.
now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.
Let
x-------------> <span>original price of the skates
we know that
15% of x is </span><span>$19.50
so
0.15x=19.50---------> x=19.50/0.15-----------> x=$130
the answer is
the </span>original price of the skates was $130<span>
</span>
Answer:
Use a website called Desmos and click on the graphing calculator
Step-by-step explanation:
Type all of those equations in the graphing calculator and the one that is the same as the graph above is the correct one!
Answer:
Missing length = 12
Step-by-step explanation:
Let x represent the missing length.
Since the triangles are similar, ∆KLM ~ ∆KRS, therefore, the ratio of their corresponding side lengths would be the same. This implies that:
KL/KR = KM/KS
KL = 65
KR = 65 - 52
KR = 13
KM = 60
KS = x
Plug in the values
65/13 = 60/x
Cross multiply
65*x = 60*13
65x = 780
Divide both sides by 65
65x/65 = 780/65
x = 12
