<h3>Notice This is example of another question u can try this like it</h3>
Step-by-step explanation:
Say, length of one piece = x inch
Length of second piece = 3x inch
3x+x= 188
4x= 188
x= 47
One piece = 47 inches
Other piece= 141 inches

Step-by-step explanation:
Answer:
D
Step-by-step explanation:
the slope is 12/10 which simplifies to 6/5 and the y intercept is 2
The value of ac is -1
Step-by-step explanation:
Let us revise some rules
- The slope-intercept form of the linear equation is y = m x + b, where m is the slope of the line and b is the y-intercept
- The product of the slopes of the perpendicular lines is -1
∵ The equation of the first line is y = a x + b
- The equation of the line in the slope-intercept form
∴ m = a
∴ The slope of the line = a
∵ The equation of the second line is y = c x + d
- The equation of the line in the slope-intercept form
∴ m = c
∴ The slope of the line = c
∵ The two lines are perpendicular
∵ The product of the slopes of the perpendicular lines is -1
- Multiply the two slopes and equate the product by -1
∴ (a)(c) = -1
The value of ac is -1
