Line j has a slope of − 2. Line d is perpendicular to line j and passes through the point( − 8 , 3 ). Write the equation for

Zina [86]

Answer:

The equation is: y = 1/2x + 7

Step-by-step explanation:

The slope of j is -2. The slope of a line perpendicular to line j has a negative inverse: 1/2. The point is (-8, 3).

Use the point slope form of the equation:

y - y1 = m(x - x1)

Substitute:

y - 3 = 1/2(x - (-8))

y - 3 = 1/2x + 4

y = 1/2x + 4 + 3

y = 1/2x + 7

Proof:

Solve for f(x) when x = -8.

f(x) = 1/2x + 7

f(-8) = 1/2(-8) + 7

= -8/2 + 7

= -4 + 7

= 3, giving the point (-8, 3)

X+4/x-1 divided by x^2 +x/x-1<br> 3/2x-1 subtract by 5/2x-1 <br> how do you do them

ElenaW [278]

$\frac{x + 4}{x - 1} / \frac{x^{2} + x}{x - 1} = \frac{x + 4}{x - 1} * \frac{x^{2} + x}{x - 1} = \frac{(x + 4)(x^{2} + x)}{(x - 1)(x - 1)} = \frac{x^{3} + x^{2} + 4x^{2} + 4x}{x^{2} - x - x + 1} = \frac{x^{3} + 5x^{2} + 4x}{x^{2} - 2x + 1} = x + 7 + \frac{17x - 7}{x^{2} - 2x + 1}$

$\frac{3}{2x - 1} - \frac{5}{2x - 1} = -\frac{2}{2x - 1}$

Nina's grandmother deposits 3000 into a saving account for her account pays 5.5% simple interest on an annual basis if she does

sashaice [31]

Answer:

$288.8

Step-by-step explanation:

Using I=Prt, we know that the 3000 is the P, 5.5% is the r, and 21 months is the t. The t goes by years, so 21 months=1.75 years. To find the interest, we do 3000*5.5%*1.75 which is 288.75. Then the problem requires you to round to the nearest tenth, so now, the answer is $288.8

in 2015, the population of a small town in florida is 95. if the population increases 15% very year, approximately what will the

ella [17]

Answer:

The approximate population of the town in 2023 will be 291

Step-by-step explanation:

In 2015, the population of a small town in Florida is 95

So, The population of a small town in Florida = 95

Now, The increase in the population of a small town in Florida is 15%

We need to find the approximate population of the small town in 2013

Number of years from 2015 to 2023 = 8 years

So, we need to find the population increase in 8 years with the rate of 15%

Thus, The increased population = initial population × ( 1 + 15%)^8

⇒ The increased population = 95 × 1.15^8

= 290.61 ≈ 291

Therefore, The approximate population of the town in 2023 will be 291
