The answer is -1, when adding both sides.
To find the y intercept, you cover x and it's coefficient and then divide -20 by 4 to get -5. To find the x intercept, you cover y and it's coefficient and divide 5 by -20 to get -4. So, x = -4 and y= -5
Please mark me brainless :)
t = 2 → A true
given I = PRT
to find T , divide both sides by PR
note that R = 6% =
= 0.06
T =
= 42/( 350 × 0.06 ) = 2
X2 + 2x + 10 =0
Can also be written as 2x +2x + 10 =0
4x + 10 =0
4x = -10
x= -10/4
x= -5/2
