Solution :

It says multiply 8 by 12 and then add 9

reading the sentence it is clear that priority is given to multiplication of 8 and 12 , once it is done then we would add 9 .

Let us first write multiplying 8 and 12 which makes it 8 x 12

the result is being add to 12 so we place 8x12 in parenthesis then add 12

which , makes it : ( 8x12) + 9

this matches to now of the given options so it is because multiplication is always given a priority comparing to addition so here parenthesis is not that important .

we can write it without parenthesis like : 8x12 +9

Answer is third option .

Answer:

30°

Step-by-step explanation:

Consecutive interior angles are supplementary when the lines are parallel:

2x +4x = 180°

x = 180°/6

x = 30°

_____

Comment on units

A lot of times the angles are assumed to be measured in degrees. Using that assumption, x=30 (degrees). When no units are specified, the angle measure defaults to radians. In radians, x = π/6. (We rarely see problems of this nature where the angles are expected to be measured in radians. More often, we see poorly edited questions where angles need to be assumed to be measured in degrees.)

Write as a polynomial. a(a+9b)^2

Alex Ar [27]

Answer: a^3+81ab^2
First, you square (a+9b) which will become (a^2+81b^2)
Then, you multiply it by a and you will get a^3+81ab^2

Ted and Meg have each drawn a line on the scatter plot shown below:

expeople1 [14]

Answer:

A.)Line P, because it is closest to most data points

Step-by-step explanation:

The line of best fit is a line which best represents the data and the data points are closely related to it.

It is also known as a trend line.

The line of best fit may pass through, some , none or all of the data points.

Also if the scatter plot does not pass through all the data point then the magnitude of positive residual must be approximately equal to the magnitude of negative residual of the data points.

Hence, by looking at the scatter plot we see that all the data points lie above Line R.

Hence, the Line R will not be a line of best fit.

But all the data points lie close to the line P , hence it act as a line of best fit.

Answer:

A] The slope of f(x) is greater than the slope of g(x).

Step-by-step explanation:

First, you need to calculate the slope of f(x) and g(x) using the slope formula

m = (y2 - y1) / (x2 - x1)

where (x1, y1) and (x2, y2) are points of the functions.

To calculate the slope of f(x) you can choose two points from the graph, in this case (0, -1) and (3, 1). Remember you can choose the points you want as long they are on the graph.

m = 1 - (-1) / 3 - 0

m = 1 + 1 / 3

m = 2 / 3

m = 0.66...

To calculate the slope of g(x) you can choose two points from the table, in this case (0, 2) and (5, 4).

m = 4 - 2 / 5 - 0

m = 2 / 5

m = 0.4

So the slope of f(x) is greater than the slope of g(x).
