Find the equation of the line that:

Mathematics

Alex Ar [27]3 years ago
7 0

Answer:

Point-Slope:  (y - 4) = 3(x - 0)

y=mx + b:  y = 3x + 4

Step-by-step explanation:

When a line is parallel, that means that it has a different y-intercept but the same slope.

So, the slope of the new line is the same:  3

<u>Step 1:  Use point slope form</u>

(y - y1) = m(x - x1)

(y - 4) = 3(x - 0)

(y - 4) = 3x

<u>Step 2:  If needed convert to y = mx + b</u>

y - 4 + 4 = 3x + 4

y = 3x + 4

X²- 12x + a = (x-b)² <br>Find the Value of a and value of b <br>​
maxonik [38]

Answer:

a = 36 , b = 6

Step-by-step explanation:

expand the right side using FOIL and compare coefficients with like terms on left side.

(x - b)²

= x² - 2bx + b² , compare to x² - 12x + a , then

- 2b = - 12 ( divide both sides by - 2 )

b = 6

and a = b² = 6² = 36

Student Debt – Vermont: The average student loan debt of a U.S. college student at the end of 4 years of college is estimated to
mezya [45]

Answer:

The confidence interval is (24116.3878,24883.6122).

Step-by-step explanation:

We are given the following information in the question:

Population mean, \mu = $23,500

Sample mean,\bar{x} = $24,500

Sample standard deviation,s = $2,800

Sample size, n =  146

Confidence interval:

\bar{x} \pm t_{critical}\frac{s}{\sqrt{n}}  

Putting the values, we get,

t_{critical}\text{ at}~\alpha_{0.05} = \pm 1.655436

24500 \pm 1.65543(\frac{2800}{\sqrt{146}} ) = 24500 \pm 383.6122 = (24116.3878,24883.6122)

The confidence interval is (24116.3878,24883.6122).
