Answer: -1.5 <= x < 1

Solution

The domain of the function is the values that the valriable x can take. According with the graph the variable x can take values between -1.5 (including because of the black point) and 1 (excluding because of the white point), then:

-1.5 <= x < 1

Write the equation of the line that passes through the points (3,5)(3,5) and (6,7)(6,7). Put your answer in fully simplified poi
nika2105 [10]

The equation of the line will be y = ( 2 / 3 ) x + 3.

<h3>What is an equation of the line?</h3>

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

Given that the equation of the line that passes through the points (3,5) and (6,7).

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

First, calculate the slope of the line:-

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( 7 - 5 ) / ( 6 - 3 )

Slope = ( 2 / 3 )

The y-intercept will be calculated as follows:-

y = mx + c

5 = ( 2 / 3 ) x 3 + c

5 = 2 + c

c = 3

The equation of the line will be calculated as;-

y = mx + c

y = ( 2 / 3)x + 3

Therefore, the equation of the line will be y = ( 2 / 3 ) x + 3.

Answer:

(a) AC = 12.565 m

(b) bearing of C from A is 90°

(c) BT = 9.373 m

Step-by-step explanation:

(a) extend North line down & perpendicular to AC.

Call that perpendicular intersection "P".

∠BAC = 90° - 53° = 37°

cos 37° = AP/15

0.7986 = AP/15

AP = 11.979 m

∠PNC = 180° - 161° = 19°

∠BCP = 90° - 19° = 71°

18 cm = 0.18 m   (red flag note: 18 cm looks very out of scale for the picture)

cos 71° = CP/0.18

0.3256 = CP/0.18

CP = 0.586 m

AC = 11.979 + 0.586 = 12.565 m

(b) The bearing to C from A is 90°

(c) tan 58° = 15/x

1.6003 = 15/x

x = 9.373 m

scott started his banking account with $150 and is spending $7 per day on lunch. this situation models which type of function ​
Zina [86]

Answer:

linear function:  y = -7x + 150

Step-by-step explanation:

Scott's situation represents a linear function because he is spending $7 each day on lunch.  His initial amount in his bank account is $150 and each day he spends the same rate on lunch, $7.  So, for any amount of days - represented by 'x' in the equation, you would multiply by -7 (since he is spending) and subtract this amount from his original amount of $150.  In this equation, 'y' is equal to his total after 'x' amount of days.
