Answer:
A
Step-by-step explanation:
We can see there are 2 parts of this function: one line for x<1 (because there is a circle for x=1, meaning it disincludes it) and one line for x >= 1 (because there is a filled circle for x=1, meaning it includes it). Therefore, we can disregard choice B (because it has x <= 1 and x > 1 instead of x<1 and x>= 1).
Notice that the part that x<1 passes through the origin, meaning the y-intercept is 0. In y= mx + b form of a line, b is the y-intercept, so b = 0 and we are looking for something in the form of y = mx for x < 1. Wee see that only in choice A that this is satisfied. Therefore, the answer is A.

-10 = -3x - 82
3x = -82 + 10
3x = -72
x = -24

Answer:D’ (0, -1)
Step-by-step explanation:
Answer:
10 - 2n - 4
Step-by-step explanation:
The product of n and 2 is 2n.
Then 10 - 2n is the difference of 10 and the product of n and 2.
In conclusion, we have:
10 - 2n - 4
Answer: 9p - 1.5a
Step-by-step explanation:
Your maximum heart rate is about 220 minus your age. But it varies base on age category.
Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate.
According to the question;
Target heart rate for
women = 1/2p(418-4a)
= 209p - 2a ....... (1)
men = 1/2p(400-a)
= 200p - 0.5a .......(2)
To find the difference between the target heart rates for a fit woman and a fit man, take equation 1 from equation 2
(209p - 2a) - (200p - 0.5a)
209p - 2a - 200p + 0.5a
9p -1.5a
