Plug in x with -1
A negative number in parenthesis times an exponent is always positive.
8+3-7=4
Answer:
-5
Step-by-step explanation:
A negative times a negative always equals a positive. 5 x 9 = 45
The value of k so that the two given lines are parallel is; k = 22.5
First, the correct question is;
In line segment geometry;
- The slopes of two or more parallel lines are equal
First, we must determine the slope of the lines by rewriting the equations to resemble the equation of a line in the slope-intercept form; y = mx + c
Therefore, we have;
- y = (k/5)x - 4/5.................eqn(1)
- and y = (9/2)x + 11/2....,........eqn(2)
- Evidently, the slope of the line in equation 2 is; 9/2
.
And since the slope of parallel lines are equal;
By cross product;
k = 22.5
