Answer:

the answer is A or the first one

Step-by-step explanation:

this is because the "x" cannot have the same number. As you can see, all the other pairs have two numbers that are the same in the "x" spot. So this concludes that the top one is the answer. Sorry for the bad explanation.

An arithmetic series a consists of consecutive integers that are multiples of 4 what is the sum of the first 9 terms of this seq

frez [133]

<h3>Answer: 144</h3><h3>Step-by-step explanation:</h3><h3 />

Since, the first 9 multiple of 4 starts from 0 are,

0, 4, 8, 12, 16, 20, ................

Which is an AP,

Having the first term, $a_1 = 0$

And, the successive difference, d = 4,

Since, the sum of the n term of an AP,

$S_n = \frac{n}{2}[2a + (n-1)d]$

Hence the sum of 9 term of the above AP,

$S_9 = \frac{9}{2}[2\times 0 + (9-1)\times 4]$

$S_9 = \frac{9}{2}(0 + 8\times 4)$

$S_9 = \frac{9}{2}(32)$

$S_9 = \frac{288}{2}=144$

How do you equations like these? help a bro out pls

icang [17]

First solve for y

3x-y-2=1

subtract 3x from each side

-y-2=-3x+1

add 2 to both sides

-y=-3x+3

divide each side by -1

y=3x-3

To graph you could make a table:

x y

0 -3

graph that.... point and use rise over run for slope 3/1 and graph.

Write an equation in standard form of the line that passes through (3, 1) and has a y intercept of -2

aleksandr82 [10.1K]

Step-by-step explanation:

First of all, use substitution to find slope

(1) = m(3) - 2

3 = m3

m = 1

With both the slope and y int, you can write it in y int form

y = 1x - 2

Convert that to standard form

-x + y = -2
