lines tx and vs are perpendicular
number 1 is D
Step-by-step explanation:
dont have time to do the rest
Answer:
No solution.
Step-by-step explanation:
y = x - 8
y = x² - 2x - 3
Let's find the point where the lines meet;
x - 8 = x² - 2x - 3
x² - 2x + x - 3 + 8 = 0
x² - x + 5 = 0
Applying the quadratic formula method we get,
It will give the value of "x" a complex number hence that graph does not have a solution.
It is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)<span>(1/4) = 0
</span>factor 1/4
(4v - 14)(4v - 2)(1/2)<span>(1/2)</span> = 0
and divide each:
(2v - 7)(2v - 1) = 0
