Answer:
A
Step-by-step explanation:
4(x+3)+3(5-x)
=4x+12+15-3x
=x+27
X = y + 5
-y + x - x = y - y + x + 5
-y = x + 5
y = x - 5
Substitute all values for x and y into their placement
y<1-6x
(1)<1-6(-1)
1<7
The coordinate pair is (-1,1)
Answer:
2
Step-by-step explanation:
The discriminant is the quantity under the radical in the quadratic formula ...
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[tex]
When that quantity is positive, the square root is real, and the formula gives two real values for x.
