If 3x-8=-2 fins the value of x-6
adell [148]

Steps to solve:

3x - 8 = -2; x - 6

~Substitute

3(x - 6) = -2

~Distribute left side

3x - 18 = -2

~Add 18 to both sides

3x = 16

~Divide 3 to both sides

x = 16/3

Best of Luck!

Find the sum of first 15 terms of an AP whose 4th and 9th t terms are -15 and -30 respectively.
Serga [27]

Answer:

Sum of the first 15 terms = -405

Step-by-step explanation:

a + 3d = -15 (1)

a + 8d = -30 (2)

Where,

a = first term

d = common difference

n = number of terms

Subtract (1) from (1)

8d - 3d = -30 - (-15)

5d = -30 + 15

5d = -15

d = -15/5

= -3

d = -3

Substitute d = -3 into (1)

a + 3d = -15

a + 3(-3) = -15

a - 9 = -15

a = -15 + 9

a = -6

Sum of the first 15 terms

S = n/2[2a + (n − 1) × d]

= 15/2 {2×-6 + (15-1)-3}

= 7.5{-12 + (14)-3}

= 7.5{ -12 - 42}

= 7.5{-54}

= -405

Sum of the first 15 terms = -405

a car generally depreciates 25% of its original value in the first year lonnoes car is worth $27300.00 after the first year. Wha
ivolga24 [154]
First, we convert the percentage to a decimal.
25% - 0.25

Next, we times this by the cars current value.
0.25 x $27,300
= $6,825

Lastly, we add this to our original cost to determine the starting value of the car.
$27,300 + $6,825
= $34,125
Cheers!

Natalija [7]

Answer:

Step-by-step explanation:

For problem #1 identify the coordinates of the point of intersection of the two lines.  This point is (4, 2), and this is the solution to #1.

In problem #2 the lines never cross, and thus we conclude that there is no solution.
