Answer:
it means to find the undefined number
we should solve for the variable to find the answer to the equation
we solve for the variable by using the elimination method
Step-by-step explanation:
Answer:
x = -5
y = 6
Step-by-step explanation:
3x + 7y = 27 --------------(I)
-3x + y = 21 -----------(II)
Add equation (I) & (II) and so x will be eliminated and we can find the value of y.
(I) 3x + 7y = 27
(II) <u> -3x + y = 21 </u> {add}
8y = 48
y = 48/8
y = 6
Plugin y = 6 in equation (I)
3x +7*6 = 27
3x + 42 = 27
3x = 27 - 42
3x = -15
x = -15/3
x = -5
The answers would be 49,51,and53!
The line is positive
The line is positive because it slants to the right.
It wouldve been negative if it slanted to the left.
Answer: A. An OPEN circle on the number 5 and an arrow shading to the RIGHT.
