Find the sum of nth term of the series 5+7+13+31... .​
Rom4ik [11]
The sequence increases in increments of the sum of the term before and the increment for the term before to the current term. For example, 7+5 is 13 and 13+5 is 18 hence the next term is 13+18 is 31. The next term is thus 80. It’s easier to understand if you draw out the term and the number it increases by

Solve (X + 6)(x - 4) = -16<br> O {-4, 6)<br> O {-4, 2]<br> O (-12, 22)
masya89 [10]

Answer:

x=2 or x=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+6)(x−4)=−16

Step 1: Simplify both sides of the equation.

x2+2x−24=−16

Step 2: Subtract -16 from both sides.

x2+2x−24−(−16)=−16−(−16)

x2+2x−8=0

Step 3: Factor left side of equation.

(x−2)(x+4)=0

Step 4: Set factors equal to 0.

x−2=0 or x+4=0

x=2 or x=−4

Find the distance between the points 3,7 and 15, 12 on the coordinate plane?
lana [24]
\text{Distance } = \sqrt{ (x_2 -x_1)^2 + (y_2 - y_1)^2}

\sqrt{ \left( 15 -  3\right)^2 +  \left( 12 -  7\right)^2}\\\\\sqrt{\left( 12\right)^2  + \left( 5\right)^2}\\\\\sqrt{    144  +   25 }\\\\\\ \sqrt{   169 } = \boxed{\bf{ 13}}

Someone Please Help Quickly! Its an Easy Question
Paul [167]

Answer:

y=\frac{2}{3}x-6

Step-by-step explanation:

Use the slope-intercept form:

y=mx+b

m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:

b=-6

y-intercept=(0,-6)

To find the slope, take any two points from the line:

(6,-2)(3,-4)

Use the slope formula for when you have two points:

\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}

The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:

(6(x_{1}),-2(y_{1})\\(3(x_{2}),-4(y_{2})

\frac{-4-(-2)}{3-6}

Simplify parentheses (two negatives makes a positive):

\frac{-4+2}{3-6}

\frac{-2}{-3}

Simplify (two negatives make a positive):

m=\frac{2}{3}

The slope is \frac{2}{3} and the y-intercept is -6. Insert these into the equation:

y=\frac{2}{3}x-6

Finito.
