Answer:

$\frac{4}{7}$

Step-by-step explanation:

In order to find the answer to this question you must choose two points anywhere on this line as long as the line intercepts then solve for slope.

slope = change in y / change in x

$slope = \frac{y2-y1}{x2-x1}$

$P = (-1,-3)$

$P=(3,4)$

Substitute:

$\frac{3--1}{4--3}$

Solve:

$3--1=3+1=4$

$4--3=4+3=7$

$=\frac{4}{7}$

Hope this helps.

The graph that best represent the relationship between time and cost is option A as it is a proportional graph

<h3>How to know the graph that represent the relationship between time and number of team?</h3>

Each week 6 teams register to participate.

Therefore, for every week 6 team register to participate in the competition.

This simply implies as time increases , the number of participant in the competition also increase.

Therefore, the equation that can be use to represent this situation is as follows:

y = 6x

where

y = number of team registered
x = time in weeks.

Hence, the graph that best represent the relationship between time and cost is option A as it is a proportional graph. The registered team increases as the time in weeks increase.

Adiya said that the first step to solving the quadratic equation x2 + 6 = 20x by completing the square was to divide 6 by 2, squ

kicyunya [14]

Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.

Q7 Q7.) Find the unit vector in the same direction as v.

igor_vitrenko [27]

Use Pythagorean theorem:

9i-j = sqrt (9^2 - 1^2) = sqrt(81-1) = sqrt80

now divide both terms in V by that:

u = 9/sqrt(80)i - 1/sqrt(80)j
