Answer:
Assume that the two digits are x and y (x is at ones position and y is at tens position)
if we subtract the digit of a two digit number, we get 4.
this means,
x-y=4 ..................... (1)
if we interchange the digits of the number and subtract the new number from the original number we get 44.
this means,
old no. 10y+x
new no. 10x+y
10y+x-(10x+y)=44
10y+x-10x-y=44
9y-9x=44 ........................... (2)
solve the two equations:
id these two equations are solved, we get no solution.
meaning, such a number with these given conditions do not exist

If point A is between points Band C and AB = 26 and BC = 50, find AC.
24
66
78
16
Answer:
24
Step-by-step explanation:
if A is a point between B and C, then'
BA + AC = BC
GIven
AB = 26 and BC = 50
BA = 26
Substitute
26 + AC = 50
AC = 50 - 26
AC = 24
Hence thelength of AC is 24

4x + 8y = 20 and -4x + 2y = -30
Step-by-step explanation:
Given :-
4x + 8y = 20 -4x + 2y = -30Adding the equations :-
[tex]: \implies[/tex] 10y = -10
[tex]: \implies[/tex] y = -1
Put it (i) :-
[tex]: \implies[/tex] 4x - 8 = 20
[tex]: \implies[/tex] 4x = 20 + 8
[tex]: \implies[/tex] 4x = 28
[tex]: \implies[/tex] x = 28/4
[tex]: \implies[/tex] x = 7

Answer:
y=2(x + 2))^2 - 9
Step-by-step explanation:
So, whenever two negative signs are right next to each other, they make a positive. However, when they are alone, they stay negative.
With this, y=2(x-(-2))^2 + (-9) --> y=2(x + 2))^2 -9

2x-y=10 y=-4x+2 substitution method
Answer:
the solution is (2, -6)
Step-by-step explanation:
Substitute the second equation into the first, replacing y in the first:
2x - (-4x+2) = 10
Simplifying, we get:
2x + 4x - 2 = 10, or:
6x = 12, which yields x = 2.
Substituting 2 for x in the second equation yields y = -4(2) + 2 = 0, or y = -6
Then the solution is (2, -6).
