A=\frac{a+b}{2} h
A - area
h - height
a+b - sum of its top and bottom sides

20=\frac{a+b}{2} \cdot 5 \\
4 = \frac{a+b}{2} \\
a+b=8

The sum of its top and bottom sides is 8 cm.

how do you write a linear equation when given a graph or table? and how do you analyze key features of a function when given its
Agata [3.3K]
When given a graph or table, you first want to figure out the slope. Look at the graph or table, and see how much does y change when x change in a certain amount? You want it as a rise/run so if x increases 2 when y increases 3 then the slope would be 3/2.

Next, you want to find the y intercept.
Look at the y value when x is 0. If the y is -2 when x=0, then b=-2.

When given its graph, find a y value when x is 0. If the y is 4 when x=0 then b=4

If you shift the absolute value parent function, F(x) = |x|, left 4 units, what is the equation of the new function?
san4es73 [151]

Answer:

The equation of new function is: G(x)=|x+4|

Step-by-step explanation:

We are given:

If you shift the absolute value parent function, F(x) = |x|, left 4 units,

We need to find:

the equation of the new function

We know that: If we have parent function f(x) and g(x)=f(x+c) there will be horizontal translation left c units.

We are parent function, F(x) = |x|

So, Our function went translation of 4 units left

So, the new function will be:

G(x)=|x+4|

So, The equation of new function is: G(x)=|x+4|
