Draw a visual model to solve 3/8 × 8/11

dimulka [17.4K]

Answer:

Step-by-step explanation:

(3/8)*(8/11)=(3*8)/(8*11)= 24/88=12/44=6/22=3/11

or you can symplify 8 and get 3/11 right away.

Graph each equation Y=-2|-3X+3|+4 NEED HELP ASAP!!

HACTEHA [7]

Graph the absolute value by using the vertex and a few selected points

Point One: X= -1, Y= -8

Point Two: X= 0, Y= -2

Point Three: X= 1, Y= 4

Point Four: X= 2, Y= -2

Point Five: X= 3, Y= -8

The graph should look something like a mountain or an upside down V

Find the solution of the system of equations. x-y=-3 -8x+y=45

mezya [45]

Answer:

x = 17, y = 28

Step-by-step explanation:

1. Isolate for x in "x - y = -3, -8":

x - y+y = -3, -8+y

x = -11 + y

2. Substitute "x = -11 + y" in for x in the second expression:

-11 + y + y = 45

3. Simplify:

-11 + 2y = 45

4. Isolate y:

-11+11 +2y = 45+11

2y = 56

$\frac{2y}{2} = \frac{56}{2}$

y = 28

5. Substitute the new y-value into the first equation:

x = -11 + 28

x = 17

hope this helps!
