Given:
The equation is:
To find:
The value of y.
Solution:
We have,
On simplification, we get
Since LHS=RHS and the equation is free from the variable y, therefore the given equation is true for all real values of y.
Hence, all real values of y are solutions.
Answer:
Step-by-step explanation:
-2(-1) + 7y = -54
2 + 7y = -54
-2 -2
7y = -56
Divide by 7
y = -8
Answer: -22
Step-by-step explanation: the most repeated number ig
Answer:
20°
Step-by-step explanation:
x+40=60 (vertically opposite angle)
or, x=60-40
or, x=20°

Answer: Slope = -3</h3>
=======================================================
Explanation:
Pick any two rows you want. I'll pick the middle two rows where every value is positive. So I'll pick these two rows:
- x = 0 and y = 4
- x = 1 and y = 1
They lead to the points (0,4) and (1,1). Apply the slope formula for these rows.
m = (y2-y1)/(x2-x1)
m = (1-4)/(1-0)
m = -3/1
m = -3
The slope is -3
