9x1
You would add 2+7 which =9 then x+1 that’s 1 so it would be 9x1
The given equation is:
0 + 7y + 2 = 7y + 2
This equation is showing that addition of 0 leaves the expression unchanged. 0 is known as the Additive Identity this means if we add or subtract 0 from any expression, number or equation the result won't be changed.
Therefore, the equation satisfied the property of Additive Identity of Real Numbers.
Answer:
m = (2 - (-1)) / (0 - (-1)) = 3/1 = 3
y = 3 * (x - 0) + 2
y = 3 * x + 2
The lengths of the two segments below then tell whether they are congruent
YZ = 4
XW = 12
not congruent
This is further explained below.
<h3>What is a number line?</h3>
Generally, A number line is a depiction of a graded straight line that serves as an abstraction for real numbers, which are symbolized by the
Number lines are used in introductory mathematics. It is generally accepted that a real number may be assigned to each point on a number line and that each point can be assigned to a real number.
YZ = Z - Y = 1 -(-3) = 4
XW = W -X = 5 -(-7) = 12
Because the segments are not the same length, they cannot be considered congruent.
In conclusion, It is self-evident that segment YZ will not have the same length as segment XW since it is just a portion of the latter.
