Value of x

For an isosceles triangle two sides are equal
AB=BC
7x-3=9x-11.
11-3=9x-7x
8=2x
2x=8
x=8/2
x=4

AB =7x-3=7(4)-3=25 units

BC=9x-11=9(4)-11=25 units

AC=4x+1=4(4)+1=17 units

Write the algebraic expression that matches each graph.

goldfiish [28.3K]

Answer:

f(x) = |x - 2| - 2

Step-by-step explanation:

Based on the shape of the graph, it's an absolute value function.

so the template for it is f(x) = |x|

From there, you can make some additions to show how much the graph has shifted from the template equation

since the graph went over to the left by 2 units and down by 2 units, this is added into the equation as follows:

f(x) = |x - 2| - 2

Describe how to draw a line that passes through the origin and has a slope of -2/3

Bas_tet [7]

Place a dot on the origin.
A line that has a slope of $\frac{-2}{3}$ goes by this formula:
$\frac{rise}{run}$
So "rise -2" and "run 3."
Rise -2 is basically go down 2, so go down 2 units from the origin. Run 3 means go right 3 units from (0, -2).
Draw a line through (3, -2) and (0, 0).
