Answer:
-1.5
Step-by-step explanation:
4x² + 4x - 3 = 0
(2x + 3)(2x - 1) = 0
2x + 3 = 0 or 2x - 1 = 0
x = -3/2 or x = 1/2
Answer: -1.5
Answer:
A political strategist wants to test the claim that the percentage of residents who favor construction is more than 30%, so then that represent our claim and needs to be on the alternative hypothesis.
Based on this the correct system of hypothesis are:
Null hypothesis: 
Alternative hypothesis 
Step-by-step explanation:
We have the following info given from the problem:
the random sample of voters selected from the town
represent the proportion of residents favored construction
represent the value desired to test.
A political strategist wants to test the claim that the percentage of residents who favor construction is more than 30%, so then that represent our claim and needs to be on the alternative hypothesis.
Based on this the correct system of hypothesis are:
Null hypothesis: 
Alternative hypothesis 
And in order to test this hypothesis we can use a one sample z test for a population proportion and the statistic would be given by:
(1)
And with the data given we have:

Hope this helped!
First we need to find the slope of the function
The slope of a function is equal to

So now we plug this into the equation and find the slope (M will represent the slope)

So the slope is -3/2
Now we can use point-slope form.
Point slope form is represented by

So when we plug in our values we get

So the equation is
Y = -3/2X-7/2
