Answer:

y = 3x-3

Step-by-step explanation:

y = mx+b

m is your slope and b is your y-intercept

plug those numbers in

y = 3x-3

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have m = 3 and b = -3. Substitute:

To solve the inequality 12x+7<−11 OR 5x−8>40, isolate x in each equation. The solutions are x < -1.5 and x > 9.6.

To solve for the inequality 12x+7<−11 OR 5x−8>40, we first need to simplify each equation separately i.e isolate x in each separate equation.

For the inequality 12x + 7 < -11: Subtract 7 from both sides, which gives 12x < -18. Then divide by 12 which will yield x < -1.5.

For the inequality 5x - 8 > 40: Add 8 to both sides, which gives 5x > 48. Then dividing both sides by 5, we get x > 9.6.

Our answer is therefore x < -1.5 OR x > 9.6. This means that any x value satisfying either of these conditions will satisfy the original inequality.

Answer:

The image with 25, 144 and 169 represents proof of the Pythagorean Theorem.  

Step-by-step explanation:

The Pythagorean Theorem is used to find the missing side of a right triangle.  The formula is a^2 + b^2 = c^2, where 'a' and 'b' represent the legs of the triangle (the ones the form the 90 degree angle) and 'c' represents the hypotenuse (the diagonal across from the 90 degree angle).  In the case of the three squares, the area of each square is given.  The area of a square is simply the base multiplied by the height, which in the case of a square those dimensions are the same.  So, taking the square root of 25 = 5, the square root of 144 =12 and the square root of 169 = 13.  If we apply the Pythagorean Theorem formula, we get 5^2 + 12^2 = 13^2, or 25 + 144 = 169.  This image proves the Pythagorean Theorem holds true.  

Answer:

Values of n and m is; 45 and 9

Step-by-step explanation:

As per the given statement: The value of n is both 5 times as much as the value of m and 36 more than the value of m.

"value of n is 5 times as much as the value of m" means [tex]n = 5m[/tex]

"value of n is 36 more than the value of m" means [tex]n = 36 +m[/tex]

then we have an equation:

[tex]n = 5m[/tex]                          ......[1]

[tex]n = 36 +m[/tex]                     ......[2]

Substitute the value of n from equation [1] to [2] we get;

[tex]5m = 36 +m[/tex]

Subtract m from both sides we get;

5m -m = 36 + m -m

Simplify:

4m = 36

Divide both sides by 4 we get;

m = 9

Substitute the value of m=9 in equation [1];

n = 5(9)

n = 45

Therefore, the value of m = 9 and value of n =45

The value of n is 5 times the value of m and is also 36 more than the value of m. By solving two equations, we can find that the values of n and m are 45 and 9, respectively.

The value of n is 5 times the value of m and is also 36 more than the value of m. Let's represent the value of m as x. According to the given information, we can write two equations:

n = 5m

n = m + 36

Now we can solve these equations to find the values of n and m. Substituting the value of n from the first equation into the second equation, we get:

5m = m + 36

Subtracting m from both sides of the equation:

4m = 36

Dividing both sides of the equation by 4:

m = 9

Plugging the value of m back into the first equation, we get:

n = 5(9) = 45

Therefore, the values of n and m are 45 and 9, respectively.

Answer:

y = 125x+225

The programmer chargers a flat fee of 225 and then $125 per hour.

The charge for a 25 hour project is $3350

Step-by-step explanation:

To find the slope  (y2-y1)/(x2-x1)

          m = (1475-725)/(10-4)

             = 750/6

             =125

The slope is $125

Using the point slope form of the equation for a line

y-y1 = m(x-x1)

y-725 = 125(x-4)

Distribute the 125

y-725 =125x-500

Add 725 to each side

y-725+725 = 125x-500+725

y = 125x+225

The programmer chargers a flat fee of 225 and then $125 per hour.

If you have a 25 hour long project, let x =25

y = 125(25) + 225

y= 3125+225

y = 3350

For a y-intercept, the x-coordinate will always be 0.

The y-intercept is the point that a line or a function crosses the imaginary line of y, which is between x = -1 and x = 1.

This point is at x = 0, and every y-intercept will always have an x-value of 0, as that is what makes it a y-intercept.

The x-coordinate of any y-intercept is always 0. This is because the y-intercept is the point where the line crosses the y-axis, and along that axis, the x-coordinate never changes from 0.

The x-coordinate of any y-intercept is always 0. This is due to the definition of a y-intercept. A y-intercept is a point where the line crosses the y-axis. The x-axis and y-axis intersect at the point (0,0) and along the y-axis, the x-coordinate is always 0 regardless of where you are on that axis.

Imagine a horizontal line across any scatter plot. As this line moves up or down along the y-axis, the x-coordinate remains at 0, because it is not moving left or right along the x-axis. Therefore, this makes the x-coordinate of any y-intercept always 0.

Answer:

Russell:  40 pounds; Sarah:  100 pounds; and Terry:  160 pounds.

Step-by-step explanation:

The three different amounts of money are 2x, 5x and 8x, or 15x.

Terry gets 8x, whereas Russell gets 2x, and 8x - 2x = 120 pounds.

Solving for x, 6x = 120 pounds, and so x = 20 pounds.

Russell gets 2(20 pounds);  Sarah gets 5(20 pounds); and Terry gets 8(20 pounds), or 40 pounds, 100 pounds and 160 pounds.  Note that 40 pounds is 120 pounds less than 160 pounds, as required by the problem.

In this ratio problem, the total money is split into 15 portions. Each portion is worth 20 pounds. Russell gets 40 pounds, Sarah gets 100 pounds and Terry gets 160 pounds.

The subject of this question is ratios and its application to practical problems. In this problem, Russell, Sarah and Terry share money in the ratio 2:5:8, meaning the total money is shared in 15 portions (2+5+8). As we know that Russell gets 120 pound less than Terry, which would be 6 portions (8 portions for Terry - 2 portions for Russell).

Therefore, each portion of money is equal to 120 pound divided by 6, which is 20 pound. So, Russell receives 2 portions which equals 40 pound (2 x 20), Sarah receives 5 portions which equals 100 pound (5 x 20) and Terry receives 8 portions which equals 160 pound (8 x 20).

The equation of the given straight line in slope-intercept form is y = 3x + 9. The y-intercept or the point at which the line crosses the y-axis (0,9), and the rate of change or slope of the line is 3.

The equation of a line in slope-intercept form is expressed as y = mx + b where m represents the slope of the line, and b represents the y-intercept.

Given the information from the figure, the slope m is 3 and the y-intercept b is 9. Therefore, the equation of the line in slope-intercept form can be written as y = 3x + 9.

The line intersects the y-axis at (0,9) which is the y-intercept in coordinate form. The rate of change, represented by the slope, is 3, which means for every increase of 1 unit on the x-axis, the y-value increases by 3 units.

The equation representing the taxi company's charges is y = 2.50 + 1.10x. With $10, you can afford to travel approximately 6.82 miles.

The taxi company's charges can be represented by a simple linear equation. The basic charge of $2.50 is the y-intercept of the equation, which means it's the starting point before any miles are driven. The $1.10 per mile charge, on the other hand, is the slope of the line and represents the cost for each mile driven.

So the equation to represent this situation would be y = 2.50 + 1.10x where y is the total cost and x is the number of miles driven.

To find out how far you can travel with $10, you would set y to 10 and solve for x:

10 = 2.50 + 1.10x

To solve for x, subtract 2.50 from each side of the equation:

7.50 = 1.10x

So you could travel approximately 6.82 miles with $10.
