Answer:
b is the correct answer.
Step-by-step explanation:
Since the slope is negative, it can't be a or d. The y intercept is 810, so c can't be right. Therefore, b is right.
Answer:
Step-by-step explanation:
As we know that in an hour there are 3600 seconds so
1.8 x 3600 = 6480
6480 / 1609 = 4.02 miles / hr
4.02 - 2.5 = 1.5( by substracting the speed)
so correct option is D which is
Talia swims about 1.5 miles per hour faster than Alina

Answer:
#6 is called exponent
Step-by-step explanation:
(x,y) is a pair of real numbers. The meaning is: (x,y) is an ordered pair of numbers belonging to R×R=R2 .
Answer:
∠y = 62.5°
∠x = 27.5°
Step-by-step explanation:
z is right angle. ∠z = 90°
∠x = ∠y - 35
∠x + ∠y + ∠z = 180 {Angle sum property of triangle}
y - 35 + y + 90 = 180
y + y - 35 + 90 = 180 {Combine like terms}
2y + 55 = 180
2y = 180 -55 {Subtract 55 from both sides}
2y = 125 {Divide both sides by 2}
y = 125 /2
∠y = 62.5°
∠x = 62.5 - 35 = 27.5°
