Y = (2/3)x + 4
The slope of the line is 2/3 and the y-intercept is 4
Answer:
Brian: 22
Charlie: 88
Latoya: 14
Step-by-step explanation:
Set up an equation where b represents the number of messages Brian sent:
4b will represent Charlie because he sent 4 times more texts than Brian did
(b - 8) represents Latoya because they sent 8 less texts than Brian:
b + 4b + (b - 8) = 124
Add like terms:
6b - 8 = 124
6b = 132
b = 22
Now, we can plug in 22 as b to find Charlie and Latoya's number of texts:
4b = 4(22) = 88
b - 8 = 22 - 8 = 14
Answer:
17c
Step-by-step explanation:
17 × c = 17c
Answer:
g(-4) = 18.
Step-by-step explanation:
Find g(-4): we replace the x in g(x) by -4:
g(-4) = (-4)^2 + 2
= 16 + 2
= 18.
Answer:
c.Observational study. The variable of interest is the result of either correct or incorrect to each trial.
Step-by-step explanation:
Observational study is the type of study when a researcher don't influence the outcome of an experiment by imposing a treatment and only observe the outcome of an experiment. A nine year old tested professional observes therapists choices and so this is the observational study.
A nine year old tested professional observes therapists choices and the choice of therapist can be correct or incorrect. So, the variable of interest is the result of either correct or incorrect to each trial.
