No, 225’s coternimal angles consist of 585, -495, 945, and -135.
3yx-1
i think (the -1 is an exponent)
First one;
As it factorises to:
f(x) = (x - 7)(x + 4)
Which, if set equal to 0, will solve to give the desired solutions like so:
f(x) = (x - 7)(x + 4) = 0
x - 7 = 0 x + 4 = 0
x = 7 x = -4
None of the other quadratics solve to give desired solutions when set equal to 0.
2m+6
because twice m =2m and 6 more =+6
Answer:
Step-by-step explanation:
Any multiple of the given equation is also a dependent linear equation
From the equation
-5x+7y=2
Multiplying all through by any number, say 2
2(-5x)+2(7y)=2(2)
-10x+14y=4 is a dependent linear equation for -5x+7y=2
If you don't fancy using a multiple, you can write the gradient equation y=mx+c
-5x+7y=2
7y=5x+2
Dividing all through by 7 gives the equation as
y=5x/7 + 2/7
