Answer:

Step-by-step explanation:

Put 5 where x is and do the arithmetic.

f(5) = (5+1)^2 +3 = 6^2 +3 = 36 +3

f(5) = 39

Construct a frequency distribution and a frequency histogram for the data set using the indicated number of classes. Describe an

elena-s [515]

Answer and Explanation:

Number of classes = 8

Highest value =2300

Lowest value = 1250

Class width= highest value – lowest value / number of classes

= 2300 – 1250/8

= 131.25 = 132

So, we can write class as 1250+132=1382

LMNP is rotated 180 degrees clockwise around the origin. What are the coordinates of L?

Alona [7]

$\huge\boxed{L^\prime(0, -1)}$

To rotate a point around the origin by 180 degrees, multiply both parts of the coordinate point by $-1$ . (This means you go from $(x, y)$ to $(-x, -y)$ .)

$L(0, 1)$

$L^\prime(0*(-1), 1*(-1))\\\boxed{L^\prime(0, -1)}$

7. Write the equation of a line which passes through the points (-3,5) and (6,23)

faust18 [17]

Answer:

answer to the equation is

$y = 2x + 11$

Step-by-step explanation:

$y = mx + b$

first find the slope of the line using the two points

$slope \: m = \frac{y2 - y1}{x2 - x1} = \frac{23 - 5}{6 - ( - 3)} \\ = \frac{18}{9} \\ slope \: m = 2$

substitute 2 for m and use one of the points for x and y and solve for b

$5 = 2( - 3) + b \\ 5 = - 6 + b \\ 5 + 6 = b \\ b = 11$

Now that you found b, the y-intercept, you can substitute that into the equation for your line

$y = 2x + 11$
