Rotation of a point through 90-degree is about he origin in clockwise direction when point M(h,k) is rotated about the origin O through 90-degree in clockwise direction
Fit Fast: a set feet per class => y = Ax
Stepping Up: a monthly fee plus an additioal fee per class => h = Bx + C
You can discard the second and the fourth systems because they do not have the form established from the statement.
The first system produce an obvious result given that is represents an option that is always better than the other 5.5x will be lower than 7.5x + 10 for any positive value of x, and so there is no need to make any comparission.
The third system is
y = 7.5x and y = 5.5x + 10 which need to be solved to determine when one rate is more convenient than the other.
Answer: y = 7.5x and y = 5..5x + 10
Answer:
25%
Step-by-step explanation:
45 is 1/4 of 180. 1/4 is 25%.
Answer:
x = 30°
y = 5
Step-by-step explanation:
The ∆ where you find x is an isosceles ∆ because two of its sides has a length of 40 each, since the other triangle has equal angles of 60° each, it also has equal length sides of 40.
Therefore, x is a base triangle of the isosceles, thus:
x = ½(180 - (180 - 60))
x = ½(180 - 120)
x = ½(60)
x = 30°
Let's find y.
8y = 40 (sides of an equilateral ∆ are equal)
Divide both sides by 8
y = 5
Answer:
Let's simplify step-by-step.
4x+1+17
Combine Like Terms:
=4x+1+17
=(4x)+(1+17)
=4x+18
Answer:
=4x+18
