Answer:

2

Step-by-step explanation:

So!

If the d (discriminant)

d > 0 Then 2 solutions

d = 0 Then 1 solution

d < 0 Then none

36 > 0 so 2 solutions

Answer:

2 Rational Roots!

Step-by-step explanation:

If the discriminant or D

If D > 0 Then there are 2 solutions

If D = Positive Perfect Square then there are 2 Rational roots

If D = Positive Non Perfect Square then there are 2 Irational roots

If D = 0 Then there is 1 solution

If D < 0 Then there are no real roots or 2 complex roots

D or 36 > 0 and D is a perfect square so

2 Rational Roots!

Find the coordinats of P
Crazy boy [7]

\textit{internal division of a line segment using ratios} \\\\\\ A(8,6)\qquad B(-2,-9)\qquad \qquad \stackrel{\textit{ratio from A to B}}{3:2} \\\\\\ \cfrac{A\underline{P}}{\underline{P} B} = \cfrac{3}{2}\implies \cfrac{A}{B} = \cfrac{3}{2}\implies 2A=3B\implies 2(8,6)=3(-2,-9)

The formula for the nth term of an arithmetic sequence can be found using the formula a Subscript n Baseline = a Subscript 1 Bas
Gnoma [55]

The equation of nth term will be written as for n as will be (\rm a_n - a₁ + d) / d. Then the correct option is D.

The missing options are attached to the picture given below.

<h3>What is a sequence?</h3>

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.

The formula for the nth term of an arithmetic sequence can be found using the formula given below.

\rm a_n = a_1 + (n-1)d

Then arrange the equation for n, we have

\begin{aligned} \rm a_n - a_1 & \rm = nd - d\\\\\rm a_n - a_1 + d & \rm =nd\\\\\rm n & \rm = \dfrac{a_n - a_1 + d}{d}  \end{aligned}

Then the correct option is D.

2. Find the value of x. *<br> 3(x + 2)<br> RE<br> 24
Elan Coil [88]

Answer:

x=6

Step-by-step explanation:

3(x+2) = 24

Divide each side by 3

3/3(x+2) = 24/3

x+2 = 8

Subtract 2 from each side

x+2-2 = 8-2

x=6
