Answer:

y = - 5x + 3

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given

10x + 2y = - 2 ( subtract 10x from both sides )

2y = - 10x - 2 ( divide through by 2 )

y = - 5x - 1 ← in slope- intercept form

• Parallel lines have equal slopes , then

y = - 5x + c ← is the partial equation

to find c substitute (1, - 2 ) into the partial equation

- 2 = - 5 + c ⇒ c = - 2 + 5 = 3

y = - 5x + 3 ← equation of parallel line

Answer: y = - 5x + 3

Answer:

A) 3.5

Step-by-step explanation:

                4.3t + 6.8 = 8.4t - 7.55

         Subtract 8.4t from both sides,

              4.3t - 8.4t +6.8 = -7.55

        Combine like terms,

                      -4.1t  + 6.8 = -7.55

                  To isolate 't' first subtract 6.8 from both sides.

                   -4.1t  = -7.55 - 6.8

                   -4.1t  = -14.35

                Divide both sides by (-4.1)

                      t = -14.35 ÷ (-4.1)

                      t =  3.5

When the result of subtracting 13 from the sum of two consecutive numbers is 18. The numbers are 15 and 16. The correct option is d.

From the information, the result of subtracting 13 from the sum of two consecutive numbers is 18.

Let the numbers be x and x+1.

Therefore, (x + x + 1) - 13 = 18

2x + 1 - 13 = 18

2x - 12 = 18

2x = 18 + 12

2x = 30

Divide

x = 30/2

x = 15

Therefore, when the result of subtracting 13 from the sum of two consecutive numbers is 18. The numbers are 15 and 16. The correct option is d.

The width of the box whose height is given as 7 inches and length is three inches more than the width given a volume of 910 is; 10 inches.

It follows from the task content that the height of the box is; 7 inches.

Let, x = width of the box and;

x+ 3 = length of the box.

Therefore, since the volume of a box is given by the formula;

V = l × b × h

Therefore, we have;

910 = 7 (x) (x+3)

Divide both sides by; 7

130 = x² + 3x

x² + 3x -130 = 0.

(x+13) (x-10) = 0

Therefore, x = -13 or x = 10.

Ultimately, the possible values of the width are; -13 or 10.

Since the width cannot be a negative number, it follows that the width of the box in discuss is; 10 inches.

Step-by-step explanation:

Square root of 18 is equal to 3√2 in radical form and 4.24264068712 in decimal form.

The graph is a dashed line, shaded area below the boundary line since y is less than (3/4)x + 1).

Given the inequality in the question;

-3x + 4y < 4

First, rearrange the inequality in slope-intercept form ( y = mx + b )by solving for y.

-3x + 4y < 4

4y < 3x + 4

Divide each term by 4

4y/4 < 3x/4 + 4/4

y < (3/4)x + 1

Now, compare to the slope-intercept form ( y = mx + b )

y < (3/4)x + 1

Slope m = 3/4

b = 1 which gives the y-intercept: ( 0,1 ).

Now, graph a dashed line, then shade the area below the boundary line since y is less than (3/4)x + 1 ( y < (3/4)x + 1 ).

Answer: the correct answer is B.0. Step-by-step explanation: there is no value for x.

The total amount of coal delivered in these two months is equal to 6.35 tons.

A conversion factor can be defined as a number that is typically used to convert (change) a number in one (1) set of units to another, either by dividing or multiplying.

Generally speaking, an appropriate conversion factor to an equal value must be used when it is necessary to perform any mathematical conversion.

Conversion:

1 lbs = 0.0005 tons

1500 lbs = 0.75 tons

1200 lbs = 0.6 tons.

Now, we can determine the total amount of coal delivered in these two months:

Total amount of coal = 3 tons + 0.75 tons + 2 tons + 0.6 tons

Total amount of coal = 6.35 tons.

The slope of the line is equal to 1 and a point lying on the line with the given equation is (7, 3).

The equation of the line is given as y + 3 = x + 7. First, we write the equation of the line in proper form. It can be written in slope-intercept form as y = mx + c where m is known as the slope of the line and c is the intercept made by the line.

Now, according to the equation given in question.

y = x + 7 - 3

y = x + 4

If we compare this equation with the slope-intercept form of line, we get the slope equal to one.

y = mx + c

y = x + 4

=> m = 1 and c = 4.

A point which satisfies the equation y = x + 4 can be (7, 3) as

7 = 3 + 4

=> 7 = 7 (L.H.S. = R.H.S.)

Thus, slope of the line is equal to 1 and a point lying on the line with the given equation is (7, 3).

Using sine formula, the seat on a Ferris wheel is 50√3 feet closer to the ground after rotating 60°.

One of the 6 trigonometric functions is the sine function. Sine function can be described as the ratio of the length of the opposite side of the triangle to its hypotenuse.

sin x = (opposite side) / (hypotenuse)

where "opposite side" is the length of the side opposite to angle x

If the wheel rotates 60°, causing the height of the seat to decrease, using sin formula, solve for the vertical distance between the positions before and after the rotation.

sin x° = (opposite side) / (hypotenuse)

where x = 60

opposite side = vertical distance between the positions before and after the rotation

hypotenuse = radius = 200 feet/2 = 100 feet

sin 60° = opposite side / 100 feet

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube  roots, plus and minus.

Now the given expression is,

|8-40/4^3| 4^2 - 8

Solving the mod first,

Since 4^3 = 64 ; 4^2 = 16,

and 8 - 40 = -32

Therefore,

|8-40/4^3| 4^2 - 8 = |-32/64|16 - 8

Now solving

⇒ 32/64 = 1/2

Therefore we get,

|8-40/4^3| 4^2 - 8 = |-31/2| 16 - 8

Now since, |-a| = a

therefore, |-1/2| = 1/2

Therefore we get,

|8-40/4^3| 4^2 - 8 = (1/2) 16 - 8

Now, since (1/2) 16 = 8

Therefore we get

|8-40/4^3| 4^2 - 8 = 8 - 8

solving we get,

|8-40/4^3| 4^2 - 8 = 0

The subtraction of the expression 10√27 - 4√12 is 22√3.

Combining things and counting them as one big group is done through addition. In math, addition is the process of adding two or more integers together.

In mathematics, subtraction involves removing anything from a group or a number of objects. What is left in the group gets smaller when you subtract.

Consider the expression,

y = 3√20x + 8√45x - 4√5x

Now, the number in the root can also be written as:

20 = 2 × 2 × 5

45 = 5 × 3 × 3

Therefore,

y = 3√20x + 8√45x - 4√5x

y = 3( √[2 × 2 × 5] )x + 8( √[5 × 3 × 3] )x - 4√5x

y = 3 × 2√5x + 8 × 3√5x - 4√5x

y = √5x ( 3 × 2 + 8 × 3 - 4 )

y = √5x ( 6 + 24 - 4 )

The bone is approximately 16384 years old, as solved by basic algebra and logarithm.

The values of y and t can be: t = 16384, y = 16380(a). (as calculated by basic algebra and logarithm).

Let 'a' be the original amount of the object.

Then, according to question, for y = amount of carbon in the object, y = 0.14(a) (as the bone contains 14% of its original carbon-14).

We are also given that: y = a [tex]e^{-0.00012t}[/tex]

On substituting the value of y, we get: 0.14a = a [tex]e^{-0.00012t}[/tex]

By basic algebra, we can solve it as:

=> 0.14 = [tex]e^{-0.00012t}[/tex]

=> ln (0.14) = ln ([tex]e^{-0.00012t}[/tex]) (taking natural logarithm on both sides)

=> ln (0.14) = - 0.00012t (as [tex]log_b(a)^m=m(log_b(a))[/tex]; further:  [tex]log_e(e) = 1[/tex])

=> [tex]\frac{ln(0.14)}{-0.00012}[/tex] = t

=> t = 16384 years (approx.)

The values of y and t can be as follows: t = 16384, y = a (0.9998(16384)) = 16380(a).

Hence, the bone is approximately 16384 years old, as solved by basic algebra and logarithm; The values of y and t can be: t = 16384, y = 16380(a). (as calculated by basic algebra and logarithm).
