The slope of the line that is parallel to the line -7x-5y=-6 is -7/5

It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass.

Any two unique places along the line may be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the vertical change to the horizontal change in each case. We shall comprehend how to discover the slope in this piece, along with some of its uses.

Given, line is -7x-5y=-6

We have to write the given line in slope-intercept form

Then, y= (-7/5)x+(6/5)

The slope-intercept form is y= mx +c

By using the slope-intercept form,

Slope=(-7/5)

The lines that are parallel to y= (-7/5)x+(6/5) have the same slope of -7/5

Therefore, the slope of the line that is parallel to the line -7x-5y=-6 is -7/5

The graph that beast describes the slope of -2/3 passing through points (-1, 0) is in option c

Information given in the question include

a linear function graph

The data is plotted as a linear function

A linear function consists of functions where the variables has exponents of 1. The graph of linear functions is a straight line graph and the relationship is expressed in the form.

y = mx + c

The slope is represented as m, The slope by definition is the ratio change of the output values to the input values

the slope, m = -2/3

negative slopes slants from top left to bottom right as in a and c

from the graph, option c has points (-1, 0) and (0, -2/3)

m = (-2/3 - 0) / (0 - -1)

m = (-2/3) / (0 + 1)

m = -2/3

This matches with option C

Answer:  C.  174 + 10x - 6x = 102 + 10x

Each school give 12 correct answers

Step-by-step explanation:

174 + 10x - 6x = 102 + 10x

x =  number of correct answers AND,

x = number of incorrect answers

Solve for x:

174 - 102 = 10x + 6x -10x

72 = 6x

x = 12

Each school give 12 correct answers

The first table A shows the relationship between the number of sets of markers bought by the teacher and the total cost of the markers.

From given question, the cost per set of markers = $3

The teacher had a $2-off coupon to use toward the total cost of the markers bought.

It is given that the number of sets of markers bought by the teacher is x, and y is the total cost of the markers.

so, we get a linear equation as:

3x - 2 = y

From table A we can see that the data satisfied the given equation,

3x - 2 = y

when x = 3, y = 3(3) - 2 = $7

when x = 9, y = 3(9) - 2 = $25

when x = 12, y = 3(12) - 2 = $34

when x = 24, y = 3(24) - 2 = $70

Therefore, the first table A shows the relationship between the number of sets of markers bought by the teacher and the total cost of the markers.

The exponential function that can model the amount of medication in Austin's body, y, x hours is of: [tex]y = 180(0.9)^x[/tex]

The definition of the exponential function is presented as follows:

[tex]y = a(b)^x[/tex]

The parameters a and b are listed as follows:

a is the amount when x = 0.

b is the rate of change.

Given that the initial dose was of 180 micrograms, hence the parameter a is;

a = 180.

After one hour, the concentration was of 162 micrograms, hence the parameter b is;

b = 162/180 = 0.9.

Hence the equation is:

[tex]y = 180(0.9)^x[/tex]

After six hours, the concentration is given as;

According to the solving the Angle m = 124

An angle with something like a vertex point at 180 degrees is considered to be a straight angle in geometry. Basically, it produces a straight line with sides that are turned away from the vertex. "Flat angles" is another term for it.

A straight line appears to have a straight angle. Here's an illustration of a straight angle. a straight line that has a half circle in the middle and at the top to symbolize a straight angle.

The sum of all angles in triangle  = 180.

Angle A = 56

Angle B = 68

Angle C =

A + B + C = 180

56 + 68 + C = 180

124 + C = 180

C = 180 - 124

C = 56

if Angle C = 56

so we know the property of straight angle:

x + y = 130-i

x - y = 34-ii

Now,

Add i and ii,

x + y + x -y = 164

or, 2x = 164

so, x = 82

Now,

x -y = 34

or, 82 - y = 34

so, y = 48

The numbers are 82 and 48.

Let adults ticket be x and childs ticket be y.

x + y = 800

x = 800 - y - eqn i

4.5x + 6y = 4500

Substituting x's value from eqn i,

4.5(800-y) + 6y = 4500

or, 3600 - 4.5y + 6y = 4500

or, 1.5y = 900

so, y = 600

Now,

x + y = 800

or, x + 600 = 800

so, x = 200

Hence, 600 adult tickets were sold and 200 child tickets were sold.

If price p(x) =26(4)^{-x/5}, the revenue when 15 units are sold is equal to $6.09.

From the information provided, the amount of revenue with respect to price that's being generated in this scenario can be calculated by using the following function (expression):

R(x) = x × P(x)

Where:

Since the revenue function, we would simply substitute the value of the unit price and evaluate as follows:

Revenue, R(x) = x × 26(4)^{-x/5}

Substituting the given parameters into the formula, we have;

Revenue, R(x) = 15 × 26(4)^{-15/5}

Revenue, R(x) = 15 × 26(4)^{-3} or (15 × 26)/4³

The least number of items that can be produced so that the average cost is no more than $24 is 95.

According to the question,

We have the following information:

The function C(x)=−21x+2025 represents the cost to produce x items.

Cost should be no more than $24.

So, we have the following inequality to find the number of items:

-21x+2025 ≤24

Subtracting 2025 from both sides:

-21x≤24-2025

-21x ≤ -2001

Dividing both sides by -21:

x ≤ 2001/21

x ≤95.28

Hence, the least number of items that can be produced so that the average cost is no more than $24 is 95.
