The lines y = -4x and y = x are neither parallel nor perpendicular.

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.

The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.

The given equations of line are,

y = -4x and y = x,

The graph of the equations y = -4x and y = x are shown below.

Since, the slope of the line y = -4x is = -4.

And the slope of the line y = x is 1

For the parallel lines, the slope should be equal.

And for the perpendicular lines, the multiplication of slopes should be equal to -1.

In the given equations of line, the slope is neither same nor multiplication is -1.

Therefore, the lines are neither parallel nor perpendicular.

Answer:

[tex] \sf \: a) \: 60[/tex]

Step-by-step explanation:

Now we have to,

The equation is,

→ t - 72 = -12

Then the value of t will be,

Hence, the value of t is 60.

The function 4x+7 does not have a horizontal asymptote.

The horizontal asymptote of a function is a horizontal line that the graph of the function approaches as the x-values get larger or smaller.

In this case, the function 4x+7 does not have a horizontal asymptote. This is because the function is a linear function (a function of the form y = mx + b) and all linear functions have a slope (in this case, the slope is 4) but no horizontal asymptotes.

If you are given the graph of a function and you want to find its horizontal asymptotes, you can look at the degree of the function (the highest exponent of the variable). If the degree of the function is less than the degree of the denominator of the function, then the function will have a horizontal asymptote at y = 0.

If the degree of the function is equal to the degree of the denominator, then the function will have a slant asymptote (a line that the graph approaches as the x-values get larger or smaller). If the degree of the function is greater than the degree of the denominator, then the function will not have any horizontal or slant asymptotes.

Answer:

The coordinate of the midpoint is (\frac{11}{2},\frac{-13}{2}  )\\ with endpoints B(9,−8) and C(2,−5)

Step-by-step explanation:

The expression given in question can be written in an equation form and hence, we determine the unknown variable x.

An expression is a combination of terms and operator. The terms contain two or more numbers or both numbers and variables. An expression describes a mathematical concept or system of mathematical operation in a symbolic form. The expression which has an equal sign to express the equality among the terms is called equation. So, the only difference between equation and expression is the equal sign =.

The above is a mathematical expression that contains two numbers 1,3 and one variable x along with a subtraction sign, -.

The number 1 is called constant number and number 3 is called the coefficient of x.

In order to do the problem, we can put any real value of x such as x= 0, 1, 2, 3, 4, 5, 6, 7 or -1, -2, -3, -4, 5 and so on.

For each value of x, we get a result either positive or negative.

3×0 -1, when x=0

-1

3×1 -1, when x=1

the result is 2

We can also write the expression in the form of equation by putting an equal sign such as 3x-1 = 0

from the equation, we can easily get the value of x.

3x -1 =0

3x = 1

x =1/3

this is the result.

Answer:

Step-by-step explanation:

You want to know how many mL of medicine is needed for 5 days when the dose is 0.1 mg/kg per day and the concentration is 1.5 mg/mL. The dose on the first day is double that for the rest of the days.

The dose on the first day is equivalent to the dose for 2 days, so we can simply add 1 day to the time period: 5 +1 = 6 days of 0.1 mg/kg/day.

The total amount required will be ...

  (0.1 mg/kg/day) × (10 kg) × (6 days) = 6.0 mg

At a concentration of 1.5 mg/mL, the quantity required is ...

  (6.0 mg)/(1.5 mg/mL) = 4.0 mL

For 5 days, the dog will need 4.0 mL of medicine.

The factor of 6x² 11x 3 is 6x(x + 3).

The factor is a number that can be multiplied by itself to produce a specific result. It is used in mathematics and science to determine the relationship between two or more variables. For example, the factor of 4 is 2 because 2 multiplied by 2 is 4. Factors can also be used to determine the probability of an event occurring or the likelihood of a given outcome. In these cases, the factor is a measure of the degree of influence that one variable has on the other.

The factor of 6x² 11x 3 is 6x(x + 3).

This can be determined by factoring out the greatest common factor (GCF) of the expression.

The GCF of 6x² 11x 3 is 6x, and the remaining factors are x + 3.
