I need help with math 1010<br>completing the square<br>x^2-9x=10

Citrus2011 [14]

$x^2-9x=10|+20.25\\
x^2-9x+20.25=30.25\\
(x-4.5)^2=30.25\\
x-4.5=5.5 \vee x-4.5=-5.5\\
x=10 \vee x=-1$

Mary bowled six games this week. Her scores were 138,151,198,147,156, and 173. What was her average for those

erica [24]

The average of scores is 160.5

Step-by-step explanation:

Mean is the sum of all values divided by the number of values.

Given scores are:

138,151,198,147,156, and 173

The formula for average score is given by:

$Avg = \frac{Sum}{items}$

Putting values

$Avg = \frac{138+151+198+147+156+173}{6}\\Avg = \frac{963}{6}\\= 160.5$

The average of scores is 160.5

What are the coordinates of R’, the image of R(-4,3) after a reflection in the line y=x?

navik [9.2K]

Answer:

R'(3,-4)

Step-by-step explanation:

we know that

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places

The rule of the reflection across the line y=x is equal to

(x,y) ------> (y,x)

we have

R(-4,3) ------> R'(3,-4)
