Answer:

An = 5n-18

Step-by-step explanation:

hello :

note :    the n th term of an arithmetic sequence is :

An =A1+(n-1)d   ....a common difference is : d  and A1 the first term

in this exercice :   d = 2-(-3)=-3-(-8) =5      A1 =  -13

the n th term of an arithmetic sequence is :An =-13+(n-1)(5)

An = 5n -5 -13

An = 5n-18

What is the answer to the question
S_A_V [24]

The equation of the parallel line is y = –2x – 11.

Solution:

Given equation of the line is y = –2x – 5.

Slope of this line is (m_1) = –2

To write the equation parallel to this line and passes through (–4, –3).

<em>If two lines are parallel, then they have the same slope.</em>

\Rightarrow m_1=m_2

\Rightarrow m_2 =-2

<u>Point-slope formula:</u>

y-y_1=m(x-x_1)

Substitute the given values in the formula, we get

y-(-3)=-2(x-(-4))

y+3=-2(x+4)

y+3=-2x-8

Subtract 3 from both sides of the equation.

y+3-3=-2x-8-3

y=-2x-11

Hence the equation of the parallel line is y = –2x – 11.

Measure of the supplement of angle
lesya [120]
Two supplemental angles add up to 180°
So we have (A + B = 180°)
The measure of one of them is always 180° - the other.
A = 180° - B
B = 180° - A

Can someone help me with this and explain it to me please? :)<br><br> CHECK ATTACHED

23. not equivalent because the first row 3x-9y=5 then if you multiplied this equation by 2 it will be 2(3x-9y) = 2(5) so 6x-18y= 10 not 6x-9y=10


24.equivalent because the second row 2y-6x=8 multiplied by 2 is 2(2y-6x)= 2(8) so 4y-12x=16

25. equivalent because the first row 5x+3y=19 multiplied by 2 is 2(5x+3y) = 2(19) SO 10X+6Y=38 and the second row 2x+4y=20 multiplied by 5 is 5(2x+4y)= 5(20) so 10x+20y=100

What exponential function is the best fit for the data in the table?
Nonamiya [84]

Answer:

   f(x)=1/4(4)^(x-1) -4

Step-by-step explanation:

The negative value for x=2 tells you that the vertical offset cannot be positive. That rules out the 1st and 3rd choices.

You can try x=2 in the remaining functions to see which works:

  f(2) = 4(4^(2-1)) -4 = 12 ≠ -3 . . . . . . . . the 2nd choice does not work

  f(2) = (1/4)(4^(2-1) -4 = -3 . . . . . . . . . . the 4th choice matches the table

Anyone know this?!? ​
Darina [25.2K]

Answer:

C

Step-by-step explanation:

The answer simply has no solution. A solution of a system of equations is determined by how many times they intersect (with lines it will only ever have one or zero solution) and unless the angle is unnecessarily small in this question, its safe to say those line, no matter how far you go, will never have a solution.
