Answer:
x = 1
y = -24
Step-by-step explanation:
8x + y = -16
-3x + y = -5
Subtract equation one from equation two
8x - -3x + y - y = -16 - - 5
8x + 3x = -16 + 5
11x = 11
Divide both sides by 11
11x/11 = 11/11
x = 1
Now substitute 1 for x in either of the equations to get y.
Using equation one, we have
8x + y = -16
8 x 1 + y = -16
8 + y = -16
Subtract 8 from both sides
8 - 8 + y = -16 - 8
y = -24
x = 1
y = -24
Answer:
D
Step-by-step explanation:
An inequality is an expression which means more than one number is a solution. We graph the solutions on a number line to show all possible values. We graph using circles and arrows.
- Equal to and less/greater than are graphed with filled in circles on the value.
- Only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.
- We draw an arrow the direction the solutions satisfy the inequality. Generally this is the direction the inequality itself points.
This is a filled in circle on -2 so this is . This means only answers C and D are options.
Answer D points to the right.
I think the answer is C that what i think ;;:;/)
