Written as a power of ten is 256.×10^0 or 2.56×10^1
Question 1:
F(x) and g(x) are like variables, just plug into the equation.
f(x) + g(x) = (x + 6) + (12x - 7)
x+6+12x-7 = 13x-1
Question 2: f(3) + g(-1)
You plug in the x-values into the equation, and then take the answer and add them together.
f(3) = 3+4
g(-1) = 12(-1)-6
f(3) = 7
g(-1) = -18
7 + (-18) = -11
Question 3:
This is similar to question 1, plug in the variables and simplify.
9x - (7x+3)
Remember to distribute the "-"
9x - 7x - 3
2x - 3
Answer:
1/4 -or- 4
Step-by-step explanation:
take the x-axis value 16 and divide by the other x-axis value, 4.
Answer:
2.a)11.355 b)0.94625
3. divide 6 by 4
4. 0.8kg, 800g
Step-by-step explanation:
To convert one measurement to another you need to set it up so that the old measurement gets cancelled out when you multiply the conversion ratio.
2a)
the gallons on top and bottom get cancelled out leaving you with the measurement that you want
2b) ![\frac{1quart}{1} *\frac{1 gallon}{4 quarts} *\frac{3.785 milliliters}{1 gallon} = 0.94625 milliliters](https://tex.z-dn.net/?f=%5Cfrac%7B1quart%7D%7B1%7D%20%2A%5Cfrac%7B1%20gallon%7D%7B4%20quarts%7D%20%2A%5Cfrac%7B3.785%20milliliters%7D%7B1%20gallon%7D%20%3D%200.94625%20milliliters)
3) ![\frac{x}{y} \frac{6 quarts}{1} *\frac{1 gallon}{4 quarts} = 1.5 gallons](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7By%7D%20%5Cfrac%7B6%20quarts%7D%7B1%7D%20%2A%5Cfrac%7B1%20gallon%7D%7B4%20quarts%7D%20%3D%201.5%20gallons)
4) ![\frac{28 ounces}{1} *\frac{1 kilogram}{35 ounces} = 0.8 kilograms](https://tex.z-dn.net/?f=%5Cfrac%7B28%20ounces%7D%7B1%7D%20%2A%5Cfrac%7B1%20kilogram%7D%7B35%20ounces%7D%20%3D%200.8%20kilograms)
![\frac{0.8 kilograms}{1} *\frac{1000 grams}{1 kilogram} = 800 grams](https://tex.z-dn.net/?f=%5Cfrac%7B0.8%20kilograms%7D%7B1%7D%20%2A%5Cfrac%7B1000%20grams%7D%7B1%20kilogram%7D%20%3D%20800%20grams)
