I’ve provided both the answer and explanation below! Hope this helps :)
Answer:
y=2x^2 + 2x - 3 x -2 -1 0 1 2
Step By Step Explanation:
The values can be find by plugging the x values in the equation which gives us the y value ,
x -2 -1 0 1 2
y 1 -3 -3 1 9
(b) Plot the points on the graph and join by a smooth curve.
(c) The line y=1 will be passing through 1 and parallel to x-axis.
(d) solve 2x^2 + 2x - 3 = 1
Subtract 1 from both the sides ,
2x^2 + 2x - 2 = 0
Factoring out the 2 from the equation ,
2(x^2 + x - 1) = 0
x^2 + x - 1 = 0
Apply the quadratic formula
x=(-1-sqrt(5))/2 and x = (-1+sqrt(5))/5

Step-by-step explanation:
Downtown Store North Mall Store
Sample size n 25 20
Sample mean
$9 $8
Sample standard deviation s $2 $1




Standard error of difference of means = 
Standard error of difference of means = 
Standard error of difference of means = 
Degree of freedom = 
Degree of freedom = 
Degree of freedom =36
So, z value at 95% confidence interval and 36 degree of freedom = 2.0280
Confidence interval = 
Confidence interval = 
Confidence interval = 
Hence Option A is true
Confidence interval is 
Find the slope:
y₂ - y₁ / x₂ - x₁
-1 - 2 / 0 - 4
-3 / -4
3/4
y = mx + b
y = 3/4x + b
Substitute any of the point's coordinate in the equation.
I'll pick (0,-1)
y = 3/4x + b
-1 = 3/4(0) + b
-1 = 0 + b
-1 = b
y-intercept = -1
y-intercept Equation:
y = 3/4x - 1
Point-slope form:
y - 2 = 3/4(x - 4)
Standard form:
-3/4x + y = -1
Answer:
13,600 dollars
Step-by-step explanation:
So if Linda has 20 credit hours in total, and you multiply that by 650 dollars, that will equal 13,000 dollars. If you add 600 (which is the cost of the textbooks for both semesters) to that it will equal 13,600
