Answer:
(-11,-4) and (-5,-7)
Step-by-step explanation:
the rule (x,y)→(x−7,y+2) means the x-value of the coordinate decreases by 7, and the y-value of the coordinate increases by two.
Apply the rule to the 1st question by plugging in the coordinates:
(x,y)→(x−7,y+2)
(−4,−6)→((-4)−7,(-6)+2)
(−4,−6)→(-11,-4)
Let's use the same process for the 2nd question:
(x,y)→(x−7,y+2)
(2,−9)→((2)−7,(-9)+2)
(2,−9)→(-5,-7)
Answer:
x = 13 and y = 13√3
Step-by-step explanation:
Recall that sin Ф = opposite side / hypotenuse, and that
cos Ф = adjacent sice / hypotenuse.
if we recognize that the angle Ф is 30° here, then we know that:
x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.
and....
y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3
In summary, x = 13 and y = 13√3
