Write out all the pairs of numbers which can be multiplied to produce c.
Add each pair of numbers to find a pair that produce b when added. ...
If b > 0, then the factored form of the trinomial is (x + d )(x + e). ...
Check: The binomials, when multiplied, should equal the original trinomial.
Answer:
A
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 2 and (a, b) = (3, 1 ), thus
y - 1 = 2(x - 3) → A
Neither of the options are correct for the given equations.
Step-by-step explanation:
-x+y=4...................................................1
16x+y=-3...............................................2
Subtract equation 1 and 2
-x+y- 16x -y = 4+3
⇒ -17x = 7
⇒x=
⇒x= -0.4117
so,
16×-0.4417 + y = -3
⇒y= -3+6.5872
⇒y= 3.5872
So the point of intersection is (-0.4117, 3.5872)
(21 * 1.10) / 3 = 23.10/3 = 7.7....so each friend has to pay $ 7.70
