What is the number rule for 18250, 18500, 19000, 20000

vlada-n [284]

The number rule for this sequence is that each time the number goes up, it does so by whatever the previous amount added was, multiplied by two. So far we can see the sequence is +50, +25-, +500, +1000, so we assume that next it will be +2000 and the next number in the sequence will therefore be 22,000

svp [43]

Answer:

Step-by-step explanation:

Let the equation of the function represented by the table is,

y - y' = m(x - x')

Where m = slope of the line

(x', y') is a point lying on the line.

Since, slope of a line passing through $(x_1,y_1)$ and $(x_2,y_2)$ is,

m = $\frac{y_2-y_1}{x_2-x_1}$

Therefore, slope of a line passing through (18, 26) and (35, 43) is,

m = $\frac{43-26}{35-18}$

= 1

Therefore, equation of the line passing through (18, 26) and slope 1 will be,

y - 26 = 1(x - 18)

y = x - 18 + 26

y = x + 8

Therefore, missing term of the equation is 8.

Which set of coordinates satisfies the system of equations y = x − 3 and y = -2x + 1?

mariarad [96]

Point c.

You can graph the two points in a calculator to find out the answer OR you can identify the lines using the y-intercept aka b in the y=mx+b format.

Y=x - 3 has a y-intercept of -3, so look for the line where it goes through -3 on the y axis. (do the same for the other except when the y-intercept is 1)

From this, you can identify the lines and just find where they intersect.

tester [92]

Answer: $\sqrt{41}$

===========================================

Work Shown:

Use the distance formula.

$d = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}\\\\d = \sqrt{(-1-(-5))^2+(3-8)^2}\\\\d = \sqrt{(-1+5)^2+(3-8)^2}\\\\d = \sqrt{(4)^2+(-5)^2}\\\\d = \sqrt{16+25}\\\\d = \sqrt{41}\\\\$

Or you could use the pythagorean theorem, which is how the distance formula is set up.
