Write a slope-intercept equation for a line that passes through (-2,1) and (2,-7).

Answer:

x > 2

Step-by-step explanation:

when a line has an open circle it is greater/less than the number it is on, a closed circle means it could be than number, so greater than or equal to. This equation is an open circle (so it's not equal to) and is on the 2. So you know the equation is x < or > 2. To find if it's < or >, you look at what direction the line goes. This one is to the right. If you notice the > looks like an arrow pointing to the right, so you can know > is the right symbol to use. The full equation will be read, x is greater than 2. Hope this was helpful!

Answer:

62.14 miles per hour

Answer: 100 km/h is equal to 62.14 mph

So, 100 km/h is equal to 62.14 miles per hour.

Answer:

62.15 mi/hr

Step-by-step explanation:

Given:

As both speed limits are given "per hour", we only need to convert 100 km to miles.  To do this, set up and solve a ratio for "miles to kilometers", where x is the number of miles to 100 km:

[tex]\implies \sf 1 : 1.609 = x : 100[/tex]

[tex]\implies \sf \dfrac{1}{1.609} = \dfrac{x}{100}[/tex]

[tex]\implies \sf \dfrac{1}{1.609} \cdot 100= x[/tex]

[tex]\implies \sf x= \dfrac{100}{1.609}[/tex]

[tex]\implies \sf x= 62.15040398...[/tex]

Therefore, 100 km/hr = 62.15 mi/hr (2 d.p.)

3) By the time Janet pays off the loan, the total interest she would have paid is D. $941.17.

4) By the time Jane pays off the loan, the total cost of her tip is B. $4,441.17.

5) The equation to find the new balance after each month's payment is D. New balance = Previous balance - Total monthly payment.

The monthly payments can be computed by first computing the total payments (future value of the loan). Then, the above figure is divided by the number of periods.

For instance, the total cost of Janet's trip is $4,441.17.  The payments are made for 24 months. Dividing $4,441.17 by 24 gives $941.17.

N (# of periods) = 24 months (2 x 12)

I/Y (Interest per year) = 24%

PV (Present Value) = $3,500

FV (Future Value) = $0

Results:

PMT = $185.05

Sum of all periodic payments = $4,441.17 ($3,500 + $941.17)

Total Interest = $941.17

Thus, Janet would have spent $4,441.17 to obtain a loan of $3,500 for her trip at 24% interest with 24 months for repayment.

The two numbers are 8 and - 1.

A quadratic equation is of the form ax² + bx + c = 0.It has highest degree of 2 and has two roots.

According to the given question we have to find two numbers that when we add we get 7 and when we multiply we get - 8.

This can be solved by quadratic equation

x² + 7x - 8 = 0.

x =(7±[tex]\sqrt{49 + 32}[/tex] )/2.

x = (7±[tex]\sqrt{81}[/tex] )/2.

x = (7±9)/2.

x = 8 or x = - 1 .

This can also be solved by logic and practice for small numbers like two numbers multiples to - 8 and add to 7.

a + b = 7 and a×b = - 8.

(8×-1) = -8 and ( 8 - 1 ) = 7.

Based on the amount that Velma wants to buy the house for and the fixed-rate mortgage offered by her bank, her monthly house payments will come to $919.75

The monthly house payments are constant so they are an annuity. The loan amount of $195,000 will be the present value of the annuity.

The monthly rate is:

= 3.9% / 12

= 3.9/12%

The number of periods is:
= 30 x 12

= 360 months

The monthly house payments is:

195,000 = Amount x (1 - (1 + 3.9/12%)³⁶⁰) / 3.9/12%

Amount = 195,000 / 212.01344311265715516703523151038

El limite de f(x) = (2 · x² + 3 · x - 9) / (x - 1.5) cuando x = 1.5 es 4.5.

En este problema tenemos el caso de una ecuación racional cuyo numerador y denominador son polinomios.

La discontinuidad de la ecuación racional es evitable si y solo si tanto el numerador y el denominador tienen la misma raíz. La existencia de la discontinuidad evitable se comprueba mediante procedimientos algebraicos. En consecuencia, realizamos la siguiente comprobación:

f(x) = (2 · x² + 3 · x - 9) / (x - 1.5)

f(x) = [(x - 1.5) · (x + 3)] / (x - 1.5)

f(x) = x + 3

La discontinuidad es evitable y la función existe para x = 1.5, entonces:

f(1.5) = 1.5 + 3

The three lakes that Frank walked were Lakes A, B, and C. This may be deduced from the distances between the lakes as well as the total distance that Frank traveled, which was more than 35 miles but less than 40 miles.

You may determine which lakes Frank walked to by combining a total of three lakes from the set of lakes provided in the puzzle.

Assuming Frank hiked Lakes A, B, and C, the distance is;

= 6.51 + 8.74 + 21.25

= 36.5 miles

Lakes A, B, and D:

= 6.51 + 8.74 + 18.68

= 33.93 miles

Lakes A, B, and E:

= 6.51 + 8.74 + 15.33

= 30.58 miles

It can be observed that Lakes A, B, and C are the only ones that meet the requirement of having a distance of fewer than 40 miles but more than 35 miles.
