Answer:
Step-by-step explanation:
( -1 + 4)/(4 + 4)= 3/8
When 0 < a < 1, the amplitude of the graph decreases, causing the slopes of the graph to appear more "flat".
Answer:
x=1 and y= 5
Step-by-step explanation:
To solve this, lets take the first equation and find the x value.
Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.
5x+4y=16
-5x -5x
4y=-5x+16
÷4 ÷4 ÷4
y=
+4
or
y=-1+4
or
y= 5
Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:
5x+4(+4)=16
5x-5+16=16
5x+11=16
-11 -11
5x=5
÷5 ÷5
x=1 and y= 5
Answer:
Calico Crayfish has the largest range ⇒ The range = 9
Step-by-step explanation:
∵ The rang is the difference between the largest value
and the smallest value
In the Calico Crayfish the largest value is 10 and the smallest value is 1
∴ The range = 10 - 1 = 9
In the Zebra Mussel the largest value is 10 and the smallest value is 2
∴ The range = 10 - 2 = 8
In the Blue-back Herring the largest value is 10 and the smallest value is 4
∴ The range = 10 - 4 = 6
In the Shield Darter the largest value is 9 and the smallest value is 2
∴ The range = 9 - 2 = 7
∴ The largest range is 9 in Calico Crayfish
