What is the vertex of the graph of f(x) = |x – 13| + 11?

Answers

Hello,

the graph of f(x) is joint here.
It has a form of "V" with (13,11) like vertex;
It is a minimum.
It is composed of 2 half straight lines y=-x-2 (for x<13) and y=x+2 (for x>13)

Answer:

x>13

Kari and Julie are practicing for basketball tryouts. Kari makes 3 less than twice as many baskets as Julie. Write an expression with two terms for the number of baskets that Kari makes. Explain how you found your expression

Answers

Answer:

X= 2y - 3

Step-by-step explanation:

Kari makes X tryouts. She also makes 3 less than twice as many as Julie which would be X= 2y - 3

Julie makes y tryouts and twice would be 2y.

Describe how to determine the solution of a system of two linear equations by graphing.WEEELPP

Answers

Using the graphing you graph the two equations and then find the point where the two lines of the equation meet.

Hope this helps :)
1). Draw the graph of one equation.

2). On the same graph, draw the graph of the other equation.

3). If the two lines cross, the x and y at the point where they cross are the solution to the system of two equations.

4). If the two lines don't cross, then the system has no solution.

5). If they are the same line, then the two equations are the same equation, and every point on the line is a solution to it.

What is the slope of a line that is perpendicular to a line whose equation is −2y=3x+7 ?

Answers

The slope of a line that is perpendicular to a line whose equation is −2y = 3x + 7 is (2)/(3)

Solution:

Given that we have to find the slope of the line that is perpendicular to a line whose equation is −2y = 3x + 7

The slope intercept form is given as:

y = mx + c

Where "m" is the slope of line and "c" is the y - intercept

Given equation is:

-2y = 3x + 7\n\n-y = (3)/(2)x + (7)/(2)\n\ny = (-3)/(2)x - (7)/(2)

On comparing the above equation with slope intercept form,

m = (-3)/(2)

We know that product of slope of a line and slope of line perpendicular to it is -1

Therefore,

(-3)/(2) * \text{ slope of line perpendicular to it } = -1\n\n \text{ slope of line perpendicular to it } = (2)/(3)

Thus slope of line that is perpendicular to given line is (2)/(3)
