-3x-y=10

4x-4y=8

or

y = -3x - 10

P(0,-10) and P(-2, -4) on this line: Plot and connect with the Line.

y = x - 2

P(0, -2) and (2,0) on this line: Plot and connect with the Line.

P(-2,-4) is the ordered pair that is the solution for this system of EQs

On may CHECK by substituting x= -2 and y = -4 into the EQs of these Lines

Hope this helps!!!

Jennifer has run many marathons and keeps track of all of her finishing times. At a marathon last month, she finished in 350 min

suter [353]

Answer:

16%

Step-by-step explanation:

406 / 350 = 1.16

406 is 116% of 350

so 350 + 16% is 406

because 350 * 0.16 = 56

56 is 16%

350 + 56 = 406

Expand and simplify (2x+5y) (x-3y)

Dmitry [639]

Should be simple:

Let's take this one at a time.

2x(x-3y)

You'd get:
$2x^2-3xy$
for the first one.

2nd one:
5y(x-3y)
you'd get:
$+5xy-3y^2$

Put them both together:
$2x^2-3xy+5xy-3y^2$

Combine like terms.

Your Answer:
$2x^2+2xy-3y^2$
