How do you tell if a polynomial graph is positive or negative?.

The sentence translated to an equation is given by 8(x+2) = 4.

Let the variable be x which is the unknown number.

Sum of the variable and 2 is represented by (x+2) .

8 times the sum = 8 (x+2)

The sum is equal to 4.

∴  8 (x+2) = 4

Therefore the required equation is  8 (x+2) = 4 .

An equation is regarded as linear when its highest power continuously equals 1. It is also stated as a one-degree equation. A linear equation with one variable typically has the form Ax + B = 0.

In this case, the variables x is a variable while the variable B is a constant. A linear equation with two variables often has the form Ax + By = C. The variables x and y, their respective coefficients A and B, and the constant C are present in this scenario.

In contrast to a linear equation with two variables, x and y, the graph of a linear equation with one variable, x, forms a vertical line that is parallel to the y-axis and vice versa.

We can't put B in either of the middle positions, as there would only be the far end at which to put both A and C and we can't put two things in one slot. That is, XBXX would require A and C to both be in the red X in order to avoid putting them next to B...can't do that, so B can't go in the middle.

Similarly, we can't put C in either of the middle positions, as there would only be the far end at which to put both B and D and we can't put two things in one slot.

Answer: The last option, [tex]8\sqrt{2}[/tex]

Step-by-step explanation:

       When looking at this triangle, there are two things we can note about it right away. First, it's a right triangle so we can use the Pythagorean theorem. Second, the two legs of the triangle are congruent (as shown by the dash lines) so both of them are equal to 8.

       Using the Pythagorean theorem we will solve.

a² + b² = c²

(8)² + (8)² = c²

64 + 64 = c²

128 = c²

c = [tex]\sqrt{128}[/tex]

c = [tex]\sqrt{64*2}[/tex]

     c = [tex]8\sqrt{2}[/tex]

The required distance of Cori from where he started is 35km.

Distance is a quantitative or qualitative measurement of the distance between two objects or places. Distance can refer to a physical length or an estimation based on other criteria in physics or everyday usage. Because spatial cognition is a rich source of conceptual metaphors in human thought, the term is also used metaphorically to mean a measurement of the amount of difference between two similar objects or a degree of separation. The concept of a metric space is used to codify most such conceptions of distance, both physical and metaphorical.

Given,

Cori races her friend heading south for 9 kilometers, east for 20 kilometers, then south for 6 more kilometers.

The distance of Cori from starting point=9+20+6

=15+20

=35

Our aim is to construct a 90% confidence interval.

c = 0.90

[tex]\alpha[/tex] = 1- c = 1- 0.90 = 0.10

[tex]\alpha[/tex]/2 = 0.10/2 = 0.05
