Find the equation of the line that passes through the points (1, 6) and (2, 8).
By substitution in this equation, show that (3, 10) also lies on this line.

Answers

Answer:

y = 2x + 4

Step-by-step explanation:

y2 - y1/ x2- x1  

= 8 - 6 / 2 - 1

= 2

So now our equation is y = 2x + b (from y = mx+b). Now plug in the coordinates to find the y-intercept.

y = 2x + b

8 = 2(2) + b

8 = 4 + b

4 = b

The y-intercept is 4.

If we put one of the values like the x in the equation, we should get the y value.

y = 2x + 4

y = 2 (3) + 4

y = 6 + 4

y = 10

find the area of the minor sector
1 r=9cm,tita=70​

Answers

Answer:

The area is 49.5 cm^2

Step-by-step explanation:

To find the area of the sector, we are going to use the formula for the area of a sector

Mathematically, we have this as;

A = theta/360 * pi * r^2

r = 9 cm and theta = 70

Substituting these values

A = 70/360 * 3.142 * 9^2

A = 49.5 cm^2

F is directly proportional to a.
If F = 28 when a = 7 find,
F when a = 10

Answers

Answer:

Step-by-step explanation:

a=10

Step-by-step explanation:

The question can be interpreted as

F∝a

If we introduce proportionality constant k, we have

F= k.a

28= k. 7

k= 28/7

k= 4

Then the equation can be written as

F= 4.a

To find, a when F = 40?

F= 4.a

40=4 × a

a= 40/4

a= 10

Answer:

F = 40

Step-by-step explanation:

Given F is directly proportional to a then the equation relating them is

F = ka ← k is the constant of proportion

To find k use the condition F = 28 when a = 7 , then

28 = 7k ( divide both sides by 7 )

4 = k

F = 4a ← equation of proportion

When a = 10, then

F = 4 × 10 = 40

Someone :) is there anyone know what is the answer?

Answers

Answer:

answers are below

Step-by-step explanation:

a. -6 ≤ 3x < 15

steps in order to solve:

-6 ≤ 3x

= -6/3 ≤ 3x/3

= -2 ≤ x

3x < 15

= 3x/3 < 15/3

= x < 5

=> -2 ≤ x < 5

b. -3 < 2x - 1 < 7

steps in order to solve:

-3 < 2x - 1

= 1 - 3 < 2x - 1 + 1

= -2 < 2x

= -2/2 < 2x / 2

= -1 < x

2x - 1 < 7

= 2x - 1 + 1 < 7 + 1

= 2x < 8

= 2x/2 < 8/2

= x < 4

=> -1 < x < 4

c. 7 < -3n + 1 ≤ 13

steps in order to solve:

7 < -3n + 1

= -1 +7 < -3n + 1 - 1

= 6 < -3n

= 6/-3 < -3n/-3

= -2 > n

-3n + 1 ≤ 13

= -3n + 1 - 1 ≤ 13 -1

= -3n < 12

= -3n/-3 < 12/-3

= n > -4

=> -4 < n < -2

graphs are below.

Lead-the-market pay strategies. An employer may choose to establish an internal compensation strategy that is in excess of the pay rates in the prevailing marketplace. This compensation strategy may increase the supply of candidates, increase selection rates of qualified acpplicants, decrease employee turnover, increase morale and productivity, or prevent unionization efforts. However, prior to implementing a lead compensation strategy, an organization should carefully consider what benefits it expects to realize from such a strategy, keeping in mind that this type of structure has the greatest propensity of increasing overall labor costs.

The first step is nitration of benzene to give nitrobenzene, and the second step is a Friedel-Crafts alkylation using CH3CH2Cl and AlCl3.

B : Nitrobenzene is too deactivated (by the nitro group) to undergo a Friedel-Crafts alkylation. C : The nitro group will direct the incoming alkyl group para position, rather than to the meta position. D : A blocking group is required to achieve this synthesis.
