It appears that these days would be Tuesday and Friday based on the data you have provided.

Absolute Value

Absolute value is based on the numbers alone, and not the sign in front of them (negative or positive)

When considering absolute value, ignore positive and negative signs. Absolute value is indicated by terms inside of | | straight vertical lines

Example:

|3.4| = 3.4

|-3.4| = 3.4

X=-4+y and -2x-5y=15

Scrat [10]

Answer:

x=-5, y=-1

Step-by-step explanation:

Substitute x=-4+y into -2x-5y=15. So we have

-2(-4+y)-5y=15

8-2y-5y=15

-7y=7

y=-1

And x is -4+y so x= -4+(-1)= -5.

Last question of my homework pls <3

dimaraw [331]

Answer:

J(2, 5 )

Step-by-step explanation:

Using the section formula

$x_{J}$ = $\frac{1(-2)+2(4)}{2+1}$ = $\frac{-2+8}{3}$ = $\frac{6}{3}$ = 2

$y_{J}$ = $\frac{1(1)+2(7)}{2+1}$ = $\frac{1+14}{3}$ = $\frac{15}{3}$ = 5

Thus J = (2, 5 )
