8(2w-2)=7(3w+2)

16w - 16 = 21w + 14

-30 = 5w

-30/5 = w

w = -6

How do you find the value for x? <br> Find the value of x ?

bogdanovich [222]

Answer:

x = 27

Step-by-step explanation:

Both angles together form 180 degree.

Set your formula up as

180 = (5x+2) + (x + 16)

180 = 5x + 2 + x + 16

180 = 6x + 18

180 - 18 = 6x

162 = 6x

162/6 = x

27 = x

fourth,sixth and thirteenth term in this sequence A(n)= 6+(n+1)(-2) help me to find and describe the explicite formula

OleMash [197]

Hello,

A(n)=6+(n+1)^(-2)=6+1/(n+1)²

$A_{4} =6+ \dfrac{1}{(4+1)^2} =6+ \dfrac{1}{25}= \dfrac{151}{25} \\

 A_{6} =6+ \dfrac{1}{(6+1)^2} =6+ \dfrac{1}{49}= \dfrac{295}{49} \\

 A_{13} =6+ \dfrac{1}{(13+1)^2} =6+ \dfrac{1}{196}= \dfrac{1177}{196} \\

Which of the following are solutions to 2x2 – 8x - 90? Select all that apply.

Bond [772]

Answer:

x=-5, x=9

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$2x^{2} -8x-90$

equate to zero

$2x^{2} -8x-90=0$

so

$2=-1\\b=-8\\c=-90$

substitute in the formula

$x=\frac{-(-8)\pm\sqrt{-8^{2}-4(2)(-90)}} {2(2)}$

$x=\frac{8\pm\sqrt{784}} {4}$

$x=\frac{8\pm28} {4}$

$x=\frac{8+28} {4}=9$

$x=\frac{8-28} {4}=-5$

therefore

The solutions are x=-5, x=9

When a trend line is drawn on a scatterplot, there are 4 points above the trend line. About how many points should be below the

kirill [66]

<u>Answer-</u>

<em>About </em><em>4 points</em><em> should be below the trend line.</em>

<u>Solution-</u>

A Scatter Plot has points that shows the relationship between two sets of data.

A line of best fit or trend line is a straight line that best represents the data on a scatter plot.

This line may pass through some of the points, none of the points, or all of the points.

But its objective is to have the line as close as possible to all points, and as many points above the line as below.

As there are 4 points above the trend line, so there should be 4 points below that.
