Select the correct answer. what is the solution set of y = x2 2x 7 and y = x 7? a. {(0, 7), (-1, 6)} b. {(0, 7), (-7, 0)} c. {(0

Kaylis [27]

Answer:

a. {(0, 7), (-1, 6)}

Step-by-step explanation:

$y = x^{2} +2x+7\\y=x+7$

subtract the equations

$y = x^{2} +2x+7 \\- \ \ \ \ \ y=x+7\\y - y =x^{2} +2x+7-(x+7)\\0=x^{2} +x\\x = 0 \ and \ x= -1$

for $y = x^{2} +2x+7$ , substitute x = 0

$y = (0)^{2} +2(0)+7\\y = 0 +0+7\\y=7$

for $y = x^{2} +2x+7$ , substitute x = 0

$y = (-1)^{2} +2(-1)+7\\y = 1 -2+7\\y=6$

The table shows how much a store charges for certain numbers of pencils. Number of pencils (p) Cost (c) 4 $0.72 7 $1.26 12 $2.16

Arada [10]

Find the rate of change, (y2-y1)/(x2-x1), from the data given...

(2.16-1.26)/(12-7)=0.18

(1.26-0.72)/(7-4)=0.18

Since the rate is constant, this is a linear equation of the form y=mx+b. Furthermore, since 0 pencils cost 0, b=0, so the cost of the pencils is simply the number of pencils times 18 cents...

c(p)=0.18p (cost with respect to pencils is 0.18 times the number of pencils)

Basile [38]

Answer:

Gender is a categorical variable. The sum gives the total number of students in class.

Step-by-step explanation:

We are given the following in the question:

The variable Male, is categorical, even though its values are numbers.

Categorical variable:

These variable are the non parametric variable.
They do not need values to express the data.
They only use number and numerical to express the data or represent the data.
There is no relation with true value of numerical.

Thus, gender is a categorical variable. Numbers are only used to represent the data.

Numbers are just a representation.

The sum of these represent the total male and female students in class. Thus, the sum gives the total number of students in class.
