The y-coordinate of point T would be -4.5 the whole ordered paid would be (-3,-4.5).
Answer: all points 
that satisfy 
Step-by-step explanation:
The slope of the line is
So, substituting into point-slope form, the equation is
Therefore, all points that satisfy will lie on the same line.
Answer:
17
Step-by-step explanation:
The discount on the shirt is 15%
Discount = price* discount rate
= 20 * 15%
= 20 * .15
=3
The new price is the previous price minus the discount
new price = 20-3
new price = 17
Answer:
cosine of angle a = 8/17
Step-by-step explanation:
Hello there!
Remember these are the trigonometric ratios
SOC CAH TOA
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
And we are asked to find the Cosine of angle A
Remember cosine is adjacent over hypotenuse
Hypotenuse - The longest side
Adjacent - the side that's not the hypotenuse nor the opposite
The adjacent side length of angle A is equal to 8 and the hypotenuse is equal to 17
so the cosine of angle a = 8/17
