The sum of two numbers is 0. Twice the smaller number subtracted from 3 times the larger number is 10. Let x represent the large

Bezzdna [24]

Answer:

x+y=0 and 3x-2y=10

Step-by-step explanation

Let the numbers be x and y.

The sum of the two numbers is 0

$\implies \: x + y =0$

Letting the smaller number be y and the

larger number be x:

twice the smaller number

$\implies \: 2y$

Also, 3 times the larger number

$\implies \: 3x$

Now ,twice the smaller number subtracted from 3 times the larger number is 10.

$\implies \: 3x - 2y = 10$

Therefore the equations are

$x + y =0$

and

$3x - 2y =10$

Find an equation for the line that passes through the point (-3, 6), parallel to the line through the points (0,-7) and (4,-15).

Vitek1552 [10]

Broken down into steps:

1. Find the slope of the line segment that connecs the points (0,-7) and (4,-15).

2. Start with the point-slope formula for the equation of a straight line:

y-b = m(x-a), where the given point is (a,b). Borrow the value of m that you calculated in (1), above, and insert it into this point-slope formula.
Finish up by subst. the x- and y-values in (-3,6) into this formula.

Done!

You could, of course, solve this result for y if you wished.

Factor 10c^2-60cd +80d^2

ozzi

$10c^2-60cd +80d^2$

$(2c - 8d) (5c -10d)$

$this \\ is \\ because...$

$2c*5c=10c^2$

$2c * -10d=-20cd \\ -8d*5c=-40cd \\ -20cd-40cd=-60cd$

$-8d * -10d = 80d$

Let f(x) = |x|, where x can be any real number. Write a formula for the function whose graph is the

andrew11 [14]

Answer:

y = 5f(x)

Please see the picture below

Step-by-step explanation:

Given the function f(x) = |x|, to transform the function y=f(x) with a vertical scaling with scale factor of 5, you should multiply the function by 5 to obtain the result;

y = 5f(x)

Please see the picture below to see a graphic solution.
