Answer:
..
Step-by-step explanation:
no the correct point would be (7,12)
7x1=7
7+5=12
Answer:
y = 4x - 8
Step-by-step explanation:
As we can see from the graph, the line passes through (0, -8) and (2, 0).
(0, -8) is the y-intersect since that's where the line intersects the y-axis. So, b = -8.
Find the slope with the formula [ y2-y1/x2-x1 ]
0-(-8)/2-0
8/2
4
The slope is 4, so, m = 4.
Slope intercept form is found by the equation [ y = mx + b ]. With what we solved for, input it into the equation.
y = 4x - 8
Best of Luck!
Hi there!
α, β, γ are the zeroes of the polynomial x³ + px² + qx + 2
Then,
• α + β + γ = - p ---(i)
• αβ + βγ + γα = q. ---(ii)
• αβγ = - 2. ---(iii)
We're Given :-
αβ + 1 = 0 Or αβ = - 1
Substitute " αβ = - 1 " in eqn. (iii) :-
(- 1) γ = - 2
γ =
γ = 2
Now. Accr'ding to the question :-
2p + q + 5 = - 2 (α + β + γ) + (αβ + βγ + γα) + 5
= - 2 (α + β + γ) + (αβ + [ γ (β + α) ] + 5
= - 2 (α + β + 2) + [ - 1 + 2 ( α + β ) ] + 5
= - 2α - 2β - 4 - 1 + 2α + 2β + 5
= 5 - 5
= 0
∴ 2p + q + 5 = 0
~ Hope it helps!
Answer:
7x+12
Step-by-step explanation:
since its neg, it take out { and } it no use.
if its like that, you add it.
so the equation: 3x+4x
that is 7x
+12 is after
so you do 7x+12
you can't simp it. So that is the answer
100% SURE
Answer:
