Answer:
x-2x = -3 and x = 3
Step-by-step explanation:
Given the expression
y=x+5.... 1
y-2x=2.... 2
Substituting the first equation into the second we will have;
From 2;
y -2x = 2
x+5-2x = 2
x-2x +5 = 2
x-2x = 2-5
x-2x = -3
-x =-3
x =3
Hence the required equation is x-2x = -3 and x = 3
Answer:
Coordinates of the image point → (-2, 9)
Step-by-step explanation:
If a point (x, y) is translated by 'h' units left and 'k' units up then the rule for the translation will be,
(x, y) → (x - h, y + k)
Rule for the translation of a point (2, 7) by shifting 4 units left and 2 units up will be,
(2, 7) → (2 - 4, 7 + 2)
→ (-2, 9)
Coordinates of the image point → (-2, 9)
Answer:
Step-by-step explanation:
Given Equations:
Equation:1
Equation:2
Solving Equation:2 for the value of 'y'
Subtracting '5x' both sides:
Equation:3
Using substitution method: Put the value of 'y' in equation:1
Subtracting '51' both sides:
Putting the value of 'x' in equation:3
The values of 'x' and 'y' are:
Answer:
=20x2−1080x
Step-by-step explanation:
Because look =(4x)(5x+−270)
=(4x)(5x)+(4x)(−270) then you will get =20x2−1080x
