B(-4; 1)
3 units right → x + 3
2 units down → y - 2
B'(-4 + 3; 1 - 2) → B'(-1; -1)
Answer:
Step-by-step explanation:
Strictly speaking, 15% isn't precisely the same as 0.15; 0.15 is the decimal fraction used to calculate 15% of some quantity.
15% of 52 is indeed 7.8. $7.80 is the discount that is to be SUBTRACTED from the regular price ($52). Adding $7.80 to $52 is incorrect.
Also, 52 + 7.8 - 59.8 is incorrect: it's not an equation (but should be one), and we should be subtracting $7.80 from $52.
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle ABC, the tangent of angle of 30 degrees is equal to divide the opposite side to the angle of 30 degrees (AC) by the adjacent side to the angle of 30 degrees (BC)

substitute the given values

Solve for b

Answer:
solution (-2,
).
Step-by-step explanation:
Given : y =
+ 3 and x = –2.
To find : What is the solution to the system of equations.
Solution : We have given that y =
+ 3 ------equation (1)
and x = –2. ------equation (2)
On plugging the x = -2 in equation (1)
y =
+ 3
y =
+ 3 .
On simplification we get ,
y =
.
Therefore, solution (-2,
).
