The equation of the line that is parallel to the given line and passes through the point (–2, 2) is: B. y = 1/5(x) + 12/5

In order to determine the equation of this line, we would first of all calculate its slope. Mathematically, the slope of any straight line can be calculated by using this formula;

[tex]Slope,\;m = \frac{Change\;in\;y\;axis}{Change\;in\;x\;axis}\\\\Slope\;,m = \frac{y_2\;-\;y_1}{x_2\;-\;x_1}[/tex]

By critically observing the graph of the line, we can logically deduce the following points:

Point (x, y) = (0, -3)

Point (x, y) = (-5, -4)

Substituting the given points into the formula, we have;

Slope = (-4 - (-3))/(-5 - 0)

Slope = (-4 + 3)/(-5)

Slope = -1/-5

Slope = 1/5

In Geometry, two (2) lines are parallel under the following conditions:

m₁ = m₂

Note: m represents the slope.

Mathematically, the point-slope form of a line is given by this equation:

y - y₁ = m(x - x₁)

Where:

At point (-2, 2), we have:

y - 2 = 1/5(x - (-2))

y - 2 = 1/5(x + 2)

y - 2 = x/5 + 2/5

y = x/5 + 2/5 + 2

y = x/5 + 12/5

y = 1/5(x) + 12/5

The evaluated functions are as follows:

The functions can be evaluated as follows:

Therefore,

f(x) = (1 / 4)⁻ˣ

For we to evaluate the function we have to substitute each value of x in the function.

Hence, let's evaluate the following:

we will replace x in the function by -2

f(-2) = (1 / 4)⁻⁽⁻²⁾

f(-2) = (1 / 4)²

f(-2) =  1 / 16

we will replace x in the function by 1

f(1) = (1 / 4)⁻¹

f(1) = 4

we will replace x in the function by 2.

Answer:  -4.667/2.000 = -2.333

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :    y-(-7/3*x+5/2)=0

Simplify   [tex]\frac{5}{2}[/tex]

Equation at the end of step : y -  ((0 -  ([tex]\frac{7}{3}[/tex] • x)) +  [tex]\frac{5}{2}[/tex])  = 0

The left denominator is : 3  The right denominator is : 2

Least Common Multiple:      6

 y - [tex]\frac{(15-14x)}{6}[/tex]   = 0

y • 6 - [tex]\frac{(15-14x)}{6}[/tex] [tex]\frac{6y + 14x - 15}{6}[/tex]

[tex]\frac{ 6y + 14x - 15}{6}[/tex]

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 2.500 and for x=2.000, the value of y is -2.167. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of -2.167 - 2.500 = -4.667 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

Slope = -4.667/2.000 = -2.333

 x-intercept = 15/14 = 1.07143

 y-intercept = 15/6 = 5/2 = 2.50000

The inequality to represent the acceptable length of the lumber is 11 ≥ x ≤ 61.

The minimum and maximum length is 11 and 61 inches.

Inequalities are created through the connection of two expressions. It should be noted that the expressions in an inequality aren't always equal. Inequalities implies that the expressions are not equal. They are denoted by the symbols ≥ < > ≤.

The minimum length will be:

= 36 - 25

= 11 inches

The maximum length will be:

= 36 + 25

= 61 inches

Therefore, the inequality is 11 ≥ x ≤ 61.

The integer solutions in the inequality expression given as − 2 ≤ x < 3 are -2, -1, 0, 1 and 2

Inequalities are expressions that do not have equal value

As a general rule, inequalities are represented by the unequal symbols

The inequality expression is given as

− 2 ≤ x < 3

The above inequality implies that

The values in the range or domain are values greater than -2, but less than 3

This means that

-2 is inclusive of the range, while 3 is not inclusive of the range

Using the above as a guide, the values in the range are

-2, -1, 0, 1 and 2

Answer:

12, 14

Step-by-step explanation:

Let x = smaller positive even integer.

Then x + 2 is the next greater even integer.

Add the squares of the numbers.

x² + (x + 2)²

Set the sum equal to 340.

x² + (x + 2)² = 340

x² + x² + 4x + 4 = 340

2x² + 4x - 336 = 0

x² + 2x - 168 = 0

We need to factor the left side. We need 2 factors of -168 that add to 2.

168 = 2³ × 3 × 7

2² × 3 = 12

2 × 7 = 14

14 × (-12) = -168

14 + (-12) = 2

The factors are 14 and -12.

x² + 2x - 168 = 0

(x - 12)(x + 14) = 0

x - 12 = 0  or  x + 14 = 0

x = 12  or  x = -14

x = 12

x + 2 = 12 + 2 = 14

The fundamental principle of multiplication

To calculate the sum of two or more numbers, utilize the mathematical operation of multiplication. If an event can happen in m different ways and a second event can happen in n different ways after it, then the two events that happen in succession can happen in m n distinct ways.

Given that 5 backpacks can fit in the trailer for every 3 people.

Then 3 people = 5 backpacks

1 people = [tex]\frac{5}{3}[/tex] backpacks

therefore  If 9 people are going on the trip, then;

b) Add the answer from previous step 4 to the numerator 1. New numerator is 4 + 1 = 5

c) Write a previous answer (new numerator 5) over the denominator 2.

Subtract: 5/2

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 2) = 2. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 2 = 4. In the following intermediate step, cancel by a common factor of 2 gives 1/1.

In other words - five halfs minus three halfs is one.

We have the inequality:

-4 < (3x - 2)/5 ≤ 6

We multiply all the sides by 5:

-4*5 < 5*(3x - 2)/5 ≤ 6*5

-20 < 3x - 2 ≤ 30

Now, we add 2 to all the sides of the inequality:

-20 + 2 < 3x - 2 + 2 ≤ 30 + 2

-18 < 3x ≤ 32

Finally, we divide by 3:

-18/3 < 3x/3 ≤ 32/3

-6 < x < 32/3

Now, using interval notation:

x = (-6, 32/3]

This means that x takes all the values greater than -6 and less or equal to 32/3. Graphically, this is:
