Answer:
The horizontal line is the x-axis and the vertical line is the y-axis.
Step-by-step explanation:
The horizontal line is the x-axis and the vertical line is the y-axis. It's a fact. You can graph the lines by inserting the equations using the graphing calculator, which is the tab next to the one you have right now ;)
F(-1)=81+3e-.7(-1)
enter into scientific/ graphing calculator
f(-1)=89.85
It's 360,000 because the ten thousands place is the 6 and number to the right is less than 5
Answer:
200 pencils and 120 pens
Step-by-step explanation:
Let the number of pencils be x while pens be y.
Considering the cost of whole purchase then, we get the equation
0.5x+y=220
Considering the number of items bought, then the equation is
x-y=80
Adding the two equations then we have
1.5x=300
x=300/1.5=200
Consideeing that x-y=80 and x is 200 then
200-y=80
y=200-80=120
Therefore, the pencils were 200 and pens 120 pieces
The correct answer is: 3) " <span>20w⁵ </span>" .
__________________________________________
Explanation:
_________________________________________
(10w³)²<span>/ (5w) =
[ 10</span>² * w⁽³*²)<span> ] / [5w] =
(100* w</span>⁶) / 5w =
(100/5) * w⁽⁶⁻¹⁾ =
20 * w⁵ =
20w⁵ ; which is: Answer choice: 3) " <span>20w⁵ </span>" .
