Dominik [7]3 years ago

Answer:

x= -2  x=-2

Step-by-step explanation:

move over the leading coefficient and you get

3x²+12x+12

the pull out a 3 because that's your gcf and 3 cannot equal zero so you can just do without id and you get

x²+4x+4

and when you factor that you get

(x+2)(x+2)

and when you set those equal to zero you get x= -2 and x= -2

Heather can complete two problems in ten minutes, and when she started she had three problems done. joel can complete three prob
zzz [600]
 heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr

Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr

so 24 problems can be done in 1 hr

Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done

and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem

ur answer is : 30 < 24x + 5 < 50 <==

anygoal [31]

Answer:

Step-by-step explanation:

Given that college GPA is positively correlated with salary after college

This means there is a positive linear relationship between GPA and salary after college.

Or we can write one as dependent and another as independent.

Since in the given question Salary is to be found out for given GPA we can make GPA as independent variable and Salary after college dependent variable

We will find a linear relationship as

Salary = slope * GPA + intercept

So

If we use knowledge of a student's GPA to predict his or her salary, the criterion variable is __GPA_____ and the predictor variable is __Salary after college._____.
