Write an equation of the line passing through each of the following pairs of points. c (4, 0), (−2, 8)'

Tomtit [17]

Answer:

Step-by-step explanation:

First, you must find the slope of the line using the formula (y2-y1/x2-x1). For your problem that would be (8-0/-2-4)= -4/3.

Then, you would plug in the slope and the y-intercept into the slope-intercept formula (y=mx+b), where m is the slope and b is the y intercept (4).

Your answer would be y=-4/3x+4

Helps Pls

It is given in the question that

Abbie decides to start doing crunches as part of her daily workout. She decides to do 10 crunches the first day and then increase the number 2 each day after that.

So the sequence of number of crunches are

$10,12,14,16,18,.....$

Here the first term, a , ia 10 and the constant difference,d, is 2.

To find the nth term, we use the formula of nth term of arithmetic series, which is

$a_{n} = a + (n-1)d$

Substituting the values of a and d, we will get

$a_{n} = 10+(n-1)2$

Therefore , correct option is d .

The length of a car is √185 ft. Will this car fit in a garage that measure 10 ft long? If not that is the minimum length of a ga

Rina8888 [55]

10 is the square root of only 100, so I know that the square root of 185 must be longer.

The square root of 185 is about 13.6 , so the garage must be absolutely
not any shorter than 14-ft, and 15-ft or 16-ft would be even better.
