Answer:

6.  2

7. (-3/2)

Step-by-step explanation:

6. 4x - 2y = 8

  -4x          -4x

-2y = -4x + 8

y = 2x + 4

y = 2/3x + 1

reciprocal of 2/3 is -3/2

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

(6)

Given

4x - 2y = 8 ( subtract 4x from both sides )

- 2y = - 4x + 8 ( divide all 3 terms by - 2 )

y = 2x - 4 ← in slope- intercept form

with slope m = 2

Parallel lines have equal slopes, thus

Slope of parallel line is m = 2

----------------------------------------------------------

(7)

Given

y = [tex]\frac{2}{3}[/tex] x + 1 ← in slope- intercept form

with slope m = [tex]\frac{2}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex]

Answer:

9

Step-by-step explanation:

let us suppose that

(-4,-6) is (x1,y1)

and (5, -6) is (x2,y2)

we know that

distance between two points = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} \\[/tex]

                                                 [tex]=\sqrt{(5-(-4))^{2} + (-6-(-6))^{2} } \\= \sqrt{9^{2}+0 } \\= 9 units[/tex]

The answer is 5 because you can fit 365 into 15 24 times and then that would equal 360 and then you have 5 left over.

15x24=360             365

                              -  360

                                 ____

                                   5

Answer:

C

Step-by-step explanation:

10 can go into 365 10 times leaving 5 left over.

Answer:

Step-by-step explanation:

first solve for y (or x) I chose y.  

-11 + 9y = -12

(-11) - (-12) =  1

9y = 1

9/1 = 1

y=1, now for x.

-11x + 9 = -12

-12 - 9 = -21

-11x = -21

-21/-11 = -32

x = -32.

Answer:A- direct variation function

Step-by-step explanation:

h(x) = [x] + 4 is in A. direct variation function as we increase the value of x the function h(x) will also increase and vice versa.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given,  h(x) = [x] + 4, as we increase the value of x the function h(x) will also increase and vice versa.

So,  h(x) = [x] + 4 is in direct variation.

Answer:

There are 1,890 seats in the hall

Step-by-step explanation:

The number of seats in the first row = 20 seats

The number of rows in the hall = 35 rows

The number of additional seat per row = 2 Seat

Therefore, the sequence of seats in the hall is an arithmetic sequence with the first term, a = 25, the common difference, d = 2, and the number of terms, n = 35

The formula for finding the sum of n-terms of an arithmetic progression, Sₙ is given as follows;

Sₙ = n/2 × [2·a + (n  - 1)·d]

Plugging in the values, we get;

Sₙ = 35/2 × [2 × 25 + (35  - 1)×2] = 1890 seats

Therefore, there are 1,890 seats in the hall.
