Answer:
x = -1 and y = -1
Step-by-step explanation:
to solve this equation we say
let
2x-5y=3.......................................... equation 1
4y-x=-3............................................equation 2
from equation 2
4y-x=-3............................................equation 2
4y + 3 = x
i.e
x = 4y + 3 ............................................. equation 3
put x = 4y + 3 in equation 1
2(4y +3) - 5y = 3
8y + 6 -5y = 3
3y +6 = 3
3y= 3-6
3y -3
divide both sides by the coefficient of y which is 3
3y/3 = -3/3
y = -1
put y = -1 into equation 3
x = 4y + 3 ............................................. equation 3
x = 4(-1) + 3
x = -4 + 3
x = -1
therefore the value of x = -1 and y = -1 respectively
Answer: average y = -8 average y =2
ARC : -4
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
The formula to find the slope of a line is:
where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:
This means the slope of the line is -1.
Answer:
21cm
Step-by-step explanation:
<em>Solution,</em>
<em>Length of fish=40mm=40/10=4cm</em>
<em>Length of pig=25cm</em>
<em>Now, </em>
<em>Difference of their length=25cm-4cm=21cm</em>
<em />
<em>Hence,the pig is 21cm long than the fish</em>
