f(x)=-7x2+8x+2 how many x-intercepts does the graph of f have

Answer:

13

Step-by-step explanation:

44=3x+5

44-5=39

39/3=13

Answer:

13 miles driven

Step-by-step explanation:

y = 3x + 5

Y is the amount we paid, so we insert 44 into the equation.

44 = 3x + 5

Any thing you do to one side of the equation, you do to the other side, so -5 from both sides.

44-5 = 39

5-5 = 0

So you are left with:

39 = 3x + 0    (So you can ignore the 0)

Like I said earlier, anything you do to one side of the equation you do to the other so divide both sides by 3:

39 divided by 3 = 13

3 divided by 3 = 1

So now you have:

13 = 1x

So x = 13 and that is how many miles you drove.

Answer:

Step-by-step explanation:

Length L = 3 + W

Perimeter P = 42 in

Perimeter = 2L + 2W

plugin values:

42 = 2(3 + W) + 2W

42 = 6 + 2W + 2W

42-6 = 4W

W = 36 / 4

W = 9  

solve L by substituting the value of W=9 into the equation:

L = 3 + W

L = 3 + 9

L = 12

therefore, the dimensions of the rectangle:

                Length = 9 in

                Width = 12 in

The dimensions for the rectangle are 12 in and 9 in if the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.

It is defined as the two-dimensional geometry in which the angle between the adjacent sides are 90 degree. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.

Let l be the length and w  be the width of the rectangle.

Length l = 3 + w

Perimeter P = 42 in

Perimeter = 2l + 2w

42 = 2(3 + w) + 2w

w = 36/4

w = 9 in

solve for l by substituting the value of w = 9 into the equation:

l = 3 + w

l = 3 + 9

l = 12 in

Thus, the dimensions for the rectangle are 12 in and 9 in if the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches.

Answer:

Given problems:

    Line parallel that passes through (2,3);

Solution:

To solve this problem, we need to first understand what parallel lines are.

A parallel line is any two line that does not meet at any point.

In order to achieve this, both lines must have the same slope.

 So, we find the slope of the given line and write in the form for a straight line.

 Slope of line  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

      let   x₁, y₁ = (-2, -1)

              x₂, y₂ = (2 , -3)

Now input the parameters and solve for the slope;

            Slope of line = [tex]\frac{-3-(-1)}{2- (-1)}[/tex]   = [tex]\frac{-2}{3}[/tex]

Any line that would be parallel to this must have the same slope.

 Equation of a straight line;

                  y  = mx + c;

      y and x are the coordinates;

      m is the slope

      c is the y-axis intercept;

       From  (2, 3);

        y = 3 and x = 2; m = [tex]\frac{-2}{3}[/tex]

     3 = [tex]\frac{-2}{3}[/tex] x 2 + C

     3 = [tex]-\frac{4}{3}[/tex] + C

       C = [tex]\frac{13}{3}[/tex]

 So the equation of the line is;

               y = [tex]\frac{-2}{3} x[/tex]  + [tex]\frac{13}{3}[/tex]

 Multiply through by 3;

              3y = -2x + 13

The equation of the line is 3y = -2x + 13

Separate the constants and variables

3d=8−2

Add or subtract the numbers

3d=6

Answer:

A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. ... Moving the function down works the same way; f (x) – b is f (x) moved down b units.

Answer:

438,800,000

Step-by-step explanation:

The number 438 million comes first, so put 438 and then a comma.

The number 800 thousand is next, so put 800 and then a comma.

There is no number for the hundreds, tens, and ones place, so put 000 with no comma after, like this.

==================================================

The graphs cross at this point. Intersection points are solutions to systems of equations.

Put another way, (1,4) is on the blue line and on the red line simultaneously.

A point on the red line is a solution to the red equation. A point on the blue line is a solution to the blue equation.

-----------------

Checking the answer:

y = x+3

4 = 1+3 ... plug in x = 1 and y = 4 into the blue equation

4 = 4 .... solution works for the blue equation

y = 3x+1

4 = 3(1)+1 ... plug in x = 1 and y = 4 into the red equation

4 = 3+1

4 = 4 ... solution also works for the red equation

This fully confirms the solution
