Answer:
Carlos is incorrect.
Step-by-step explanation:
We have been given that a line through the origin has a slope of  . Carlos thinks the slope of a perpendicular line at the origin will be 3.
. Carlos thinks the slope of a perpendicular line at the origin will be 3. 
We know that the slope of a perpendicular line to a given line is always negative reciprocal of the slope of the given line.
The slope of the perpendicular line at the origin will be negative reciprocal of  .
. 
Let us find negative reciprocal of  as:
 as:

Since the slope of a perpendicular line at the origin is  , therefore, Carlos is incorrect.
, therefore, Carlos is incorrect.

Answer:
square root (50) = 7.071
Step-by-step explanation:
Using Pthagoras' theorem, the diagonal length is  .
.
Therefore, the diagonal length is the square root of 5^2+5^2,
= 
= 
= 7.071
 
        
             
        
        
        
1 )  Billy walks 15 miles every day to soccer practice and he had 5 practices last week. 
We know that,  1 mile = 1760 yards 
So, 15 miles = (15× 1760) yards = 26400 yards
Thus the total distance walked in 5 practices will be: 
2) Mark's current age is  years
 years 
So, his age was in 10 years ago 
Given that, his current age is 3 times his age 10 years ago. 
So, the equation to represent this situation will be :  
 
        
             
        
        
        
Hi! 
Remember that an x-intercept is a point in which the line touches the x-axis (the horizontal line). And, the y-intercept is a point in which the line touches the y-axis (the vertical/up and down line) 
-----------------
For A) 
The coordinate of the y-intercept is (0,1) 
The coordinate of the x-intercept is (3,0) 
For B) 
The coordinate of the y-intercept is (0,0) 
The coordinate of the x-intercept is (0,0) !
*both the x and y axis meet at the origin. So, a line that goes through the origin (0,0) is intersecting with BOTH the x and y-axis. 
Hope I helped! Comment if you have any questions or concerns.
