Answer:

5(x+8)-1=20+2(x+8)

or, 5x + 40 -1 = 20 + 2x + 16

or, 5x-2x = 20+ 16 -39

3x = -3

x = -1

The ratio of the weight of an object on Jupiter to its weight on earth is a 8 to 3. how much would a 180 pound person weigh on J

inna [77]

Answer:

480 pounds.

Step-by-step explanation:

By proportion:

8/3 = x/180 where x is the weight on Jupiter.

Cross multiply:

3x = 8*180

3x = 1440

x = 480 pounds.

Which Linear Equation represents the data given in the table A) y= 3x+8 B). Y=8X+3 C). Y=3X-8 D) 8X-3

Snezhnost [94]

<h2>Explanation:</h2><h2></h2>

Hello! remember that you have to write complete questions in order to get good and exact answers. Here you haven't provided any table so I'll assume a table, which is shown below:

$\begin{array}{cc}x & y\\0 & 8\\1 & 11\\2 & 14\\3 & 17\\4 & 20\end{array}$

Remember that the slope intercept form of the equation of a line is given by:

$y=mx+b$

Where:

$m:slope \\ \\ b:y-intercept$

The y-intercept occurs when $x=0$ , thus from the table:

$b=8$

And the slope can be found as:

$m=\frac{y_{2-y_{1}}}{x_{2}-x_{1}} \\ \\ m=\frac{11-8}{1-0}=3$

Therefore, the equation that represents the table is:

$y=3x+8$

Select the correct answer. Which point lies on a circle with a radius of 5 units and center at P(6, 1)? A. Q(1, 11) B. R(2, 4) C

jasenka [17]

Answer:

T(9,-2)

Step-by-step explanation:

The circle has radius 5 units and center P(6,1).

The equation of this circle is

$(x-6)^2+(y-1)^2=5^2$

$(x-6)^2+(y-1)^2=25$

If Q(1,11) lies on this circle, then it must satisfy its equation.

$(1-6)^2+(11-1)^2=25$

$(-5)^2+(10)^2=25$

$25+100=25$ , this statement is false.

If R(2,4) lies on this circle, then it must satisfy its equation.

$(2-6)^2+(4-1)^2=25$

$(-4)^2+(3)^2=25$

$16+9=25$ , this statement is false.

If S(4,-4) lies on this circle, then it must satisfy its equation.

$(4-6)^2+(-4-1)^2=25$

$(-2)^2+(-5)^2=25$

$4+25=25$ , this statement is false.

If T(9,-2) lies on this circle, then it must satisfy its equation.

$(9-6)^2+(-2-1)^2=25$

$(4)^2+(-3)^2=25$

$16+9=25$ , this statement is TRUE.

The correct answer is D
