Answer:

3/2

Step-by-step explanation:

My reasoning is that the sum of the numbers in the left is equal to the sum of the numbers in the right.

Therefore 6=2y+3

2y=6-3

2y=3

y=1.5 or 1and a half which is equivalent to 3/2

What’s different about solving inequalities when you have to multiply or divide by a negative number? Can you explain why a spec

Sergeu [11.5K]

Alright, let's take an example. 1 is less than 2, so we can write it as 1<2. However, if we multiplied both sides by -1 without changing anything else, we get -1<-2, but -1 is greater than -2 because it is less negative, so the correct way of writing it would be -1>-2. Therefore, since a number that is less positive than another becomes less negative (and therefore higher) when both are multiplied by -1, we have to change the side of the inequality

How many terms of the arithmetic progression 2,5,8..Must be taken to get a sum of 392?

AveGali [126]

Answer:

Number of term = 48

Step-by-step explanation:

GIven:

Arithmetic progression

2,5,8..

Total sum of Arithmetic progression is 392

Find:

Number of term

Computation:

First term a = 2

Difference d = 5 - 2 = 3

Sn = [n/2][2a + (n-1)d]

392 = [n/2][2(2) + (n-1)3]

392 = [n/2][4 + 3n - 3]

784 = [n][1 + 3n]

784 = n + 3n²

3n² + n - 784

n = 48 , n = -49

Number of term = 48

Write the slope-intercept form of the equation that fits the conditions.

LenaWriter [7]

Answer:

y = 3x - 17

Step-by-step explanation:

Here is the point-slope form of the equation of a line.

$y - y_1 = m(x - x_1)$

If you are given a slope, m, and a point on the line, (x1, y1), you just plug in the values into the equation above, and you get the equation of the line.

In your problem, you are given a point on the line, (5, -2). Now you need the slope of the line. Your line is perpendicular to the given line. The slopes of perpendicular lines are negative reciprocals. If you know the slope of a line, the slope of its perpendicular is found by flipping the fraction and changing the sign.

The given line has slope -1/3.

Flip -1/3 to get -3.

Now change the sign to get 3.

The slope of the line you need is 3. The line passes through point (5, -2).

Now we use the point-slope equation and we plug in the values we have.

$y - y_1 = m(x - x_1)$

$y - (-2) = 3(x - 5)$

$y + 2 = 3x - 15$

$y = 3x - 17$
