1 answer:

7 0

Y = 4x - 1
y = 2x - 5

4x - 1 = 2x - 5
4x - 2x = -5 + 1
2x = -4
x = -4/2
x = -2

y = 4x - 1
y = 4(-2) - 1
y = -8 - 1
y = -9

solution is : -2,-9)

Which equation shows an example of the associative property of addition? (–7 i) 7i = –7 (i 7i) (–7 i) 7i = 7i (–7i i) 7i × (–7i

mr Goodwill [35]

The equation which shows the associative property of addition is; (–7 + i) +7i = –7 (i +7i).

<h3>What is the associative property of addition?</h3>

Associative property of addition postulates that Changing the grouping of addends does not change the sum of the numbers. As an instance, ( 5 + 3 ) + 4 = 5 + ( 3 + 4 )

Consequently, the equation which shows the associative property of addition is; (–7 + i) +7i = –7 (i +7i)

Write the explicit<br> rule for the nth term.<br> Then find a71.<br> {O, -8, -16, -24 ...}

yulyashka [42]

Answer:

Step-by-step explanation:

{0, -8, -16, -24,...} here you add -8 each time so the rule is

$a_{1} = 0, a_{n} = a_{n-1} -8$

the 71 term is

$a_{71} = 0 + (71 - 1) * (-8) = 70 * (-8) = -560$
