Point R divides in the ratio 1 : 3. If the x-coordinate of R is -1 and the x-coordinate of P is -3, what is the x-coordinate of

dimaraw [331]

Answer:

C. 5

Step-by-step explanation:

Point R divides the line segment PQ internally. The x-coordinate of the point which divides the line segment in ration m:n internally can be calculated as:

$x=(\frac{mx_{2}+nx_{1}}{m+n} )$

Here, x1 is the x-coordinate of 1st point, x2 is the x-coordinate of 2nd point, x is the x-coordinate of point dividing the segment. We have all the values except x2. Using the given values in above formula, we get:

$-1=\frac{x_{2}+3(-3) }{1+3} \\ \\-4=x_{2}-9\\\\ 5=x_{2}$

Thus the x-coordinate of point Q will be 5

The x-coordinate of Q is 5.

Find an expression for the number in the nth term pattern of the sequence. 4 , 7 , 12, 19

EastWind [94]

Answer:

n^2 + 3.

Step-by-step explanation:

4 7 12 19

Differences are 3 5 7 so this a quadratic sequence.

2nd difference = 2 2

So the first part of the expression is n^2

Terms: 4 7 12 19

n^2 1 4 9 16

Difference = 3 3 3 3 3

So the answer is n^2 + 3.

-2(x+8)=4x+10 what is the solution set of the equation

dmitriy555 [2]

Short answer : x = -13/3

But let's solve your equation step-by-step.

-2(x+8)=4x+10

Step 1: Simplify both sides of the equation.

(Distribute)

Step 2: Subtract 4x from both sides

Step 3: Add 16 to both sides.

Step 4: Divide both sides by -6.

Answer:

x = -13/3
