Answer:
-8b^3ax^2
Step-by-step explanation:
The graph of
... y = 3/4 - 2
is a horizontal line at y = -1.25.
The graph of
... y = (3/4)x - 2
is an upward-sloping line with a rise of 3 for every 4 units to the right. It intercepts the y-axis at y = -2.
Answer:
1.you use a "carrot" it looks like this ^ so you put 6^3 an that is saying 6 to the power of 3
2. you can also use the symbols option and there is shows little numbers but only gives you the option for the power of 2 and 3
example: 6³
3. click equation option and put the x^2 and then delete the x and put the number or variable and then within the brackets put what the power should be.
Step-by-step explanation:
Total costs of sending
0,37+0,23=0,6 $
3,04:0,6= 5 2/3 but since you can’t send 2/3 of a letter you can only send 5
Answer:
2x^2 = 6x - 5.
-x^2 - 10x = 34.
These have only complex roots/
Step-by-step explanation:
3x^2 - 5x = -8
3x^2 - 5x + 8 = 0
There are complex roots if the discriminant 9b^2 - 4ac) is negative.
Here the discriminant D = (-5)^2 - 4*-5*8 = 25 + 160
This is positive so the roots are real.
2x^2 = 6x - 5
2x^2 - 6x + 5 = 0
D = (-6)^2 - 4*2*5 = 36 - 40 = -4
So this has no real roots only complex ones.
12x = 9x^2 + 4
9x^2 - 12x + 4 = 0
D = (-12)^2 - 4*9 * 4 = 144 - 144 = 0.
- Real roots.
-x^2 - 10x = 34
x^2 + 10x + 34 = 0
D = (10)^2 - 4*1*34 = 100 - 136 = -36.
No real roots = only complex roots.
