1. m=2/5 point= (3,9)

y - 9 = 2/5(x - 3)

2. m= -5 point= (-6,8)

y - 8 = -5(x + 6)

3. m= 0.5 point= (-3,-3)

y + 3 = 0.5(x + 3)

4. m= -4 point= (1,2)

y - 2 = -4(x -1)

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "11.3" was replaced by "(113/10)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

b-((113/10))>0

Rewriting the whole as an Equivalent Fraction

2.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using 10 as the denominator :

b b • 10

b = — = ——————

1 10

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

b • 10 - (113) 10b - 113

—————————————— = —————————

10 10

Equation at the end of step

10b - 113

————————— > 0

STEP

3.1 Multiply both sides by 10

3.2 Divide both sides by 10

b-(113/10) > 0

Solve Basic Inequality :

3.3 Add 113/10 to both sides

b > 113/10

Inequality Plot :

3.4 Inequality plot for

b - 11.300 > 0

One solution was found :

b > 113/10

Which number is a solution of the inequality?

b > 11.3

If the 7th of an AP is equal to 11 times the 11th term, find the 18th term

Zina [86]

Answer:

-33 or 33

Step-by-step explanation:

The seventh term of an AP is written as:

$a + 6d$

The eleventh term of an AP is written as:

$a + 10d$

If the 7th term is 11 times the 11th term, then;

$a + 6d = 11(a + 10d)$

Expand to get:

$a + 6d = 11a + 110d$

$11a - a = 6d - 110d$

$10a = - 104d$

$\frac{a}{d} = - \frac{104}{10}$

$\frac{a}{d} = - \frac{52}{5}$

We must have a=-52 and d=5

a=52 and d=-5

For the first case, the 18th term is :

$- 52 + 5 \times 17 = 33$

For the second case,

$52 - 5 \times17 = - 33$

Use the graph below to answer the following question: List the integer value(s) of x in the open interval from –2 to 5 where the

DedPeter [7]

To start off, the wording of this question is pretty technical. Let's reword the question to make it a bit easier to understand.

From the open interval from -2 to 5 (meaning between but not including those integers), list every integer for x at which x approaches a defined y point on the curve, regardless of whether it actually takes that y value at that point.

Let's start with the first eligible integer, -1.
The limit, from both sides, as x approaches -1 is y=-1.
However, y = -2 at this point.

At 0, x continuous and defined on the curve where you would expect it, and therefore the limit at x=0 is its y value at that point, 0.

x=1 is not eligible, because its left-side limit (when approaching from the left) and right-side limit (when approaching from the right), are distinct.

x=2 has a clear defined limit. It is continuous and defined at that point. The limit looks to be around y= 1.8

x=3 does not feature a clearly defined, finite value, since the limit at x=3 is
-∞

x=4, like x=0 and x=2, has a clear and finite limit, since it is continuous at that point.

Answers are x=-1, x=0, x=2, and x=4
or
{-1, 0, 2, 4}

Jorge walked 25 steps north. then he walked 75 steps south what is Jorges final position

serious [3.7K]

Answer:

If Jorge goes up 25 (positive) and then goes 75 steps south (negative). Then you have to calculate 25-75. This equals -50. We know negative distance is south so he's final position will be 50 steps south.
