Answer:

y = 2x + 1

Step-by-step explanation:

first find slops

(9-5)/(6-4) = 4/2 = 2 = m

y = mx + b

5 = 2(2) + b

1 = b

y = 2x + 1

Answer:

y = 2x - 3

Step-by-step explanation:

gradient of the line is

$\frac{9 - 5}{6 - 4 } = 2$

equation will be:

$\frac{y - 5}{ x - 4} = 2$

y - 5 = 2x - 8

y = 2x - 3

Which of the following is an improper integral?

guapka [62]

Answer:

A) $\displaystyle \int\limits^3_0 {\frac{x + 1}{3x - 2}} \, dx$

General Formulas and Concepts:

<u>Calculus</u>

Discontinuities

Removable (Hole)
Jump
Infinite (Asymptote)

Integration

Integrals
Definite Integrals
Integration Constant C
Improper Integrals

Step-by-step explanation:

Let's define our answer choices:

A) $\displaystyle \int\limits^3_0 {\frac{x + 1}{3x - 2}} \, dx$

B) $\displaystyle \int\limits^3_1 {\frac{x + 1}{3x - 2}} \, dx$

C) $\displaystyle \int\limits^0_{-1} {\frac{x + 1}{3x - 2}} \, dx$

D) None of these

We can see that we would have a infinite discontinuity if x = 2/3, as it would make the denominator 0 and we cannot divide by 0. Therefore, any interval that includes the value 2/3 would have to be rewritten and evaluated as an improper integral.

Of all the answer choices, we can see that A's bounds of integration (interval) includes x = 2/3.

∴ our answer is A.

Which method would be the most efficient method to solve x^2-6=0

Daniel [21]

Adding 6 to both sides and taking the square root, remember that x can be the poitivie and negative root
x^2-6=0
add 6
x^2=6
squaer root both sides
x=√6

x=+√6 and -√6

PLEASE help!!!!!<br> Find the measurement indicated in each parallelogram. Find m < W

romanna [79]

Your answer should be in one variable equation by using the Y and W angle. They are equal if you match with the same angle size.

7x=6x+11

(7-6)x = 11

x = 11

We got the x value, so suvtitute into W angle :

=7(11)

= 77

Hope this helps :)

What is the perimeter of a rectangle length 86ft width 9ft 10inches?

kondor19780726 [428]

The perimeter is 166.9 ft.

Convert feet to inches to make it easier to calculate. The formula to find the perimeter is... 2(w+h)

once you get your answer, convert inches back to feet.
