Answer:
y = 2x + 5
Step-by-step explanation:
First,
9-3 = 6
over
2-(-1) = 3
Then,
6 divided by 3 = 2
2 = slope
Next, using (-1,3), *you can use either ordered pair
y - 3 = 2 {x - (-1)}
y - 3 = 2x + 2
y = 2x + 5
Answer:
<u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Step-by-step explanation:
Given :
Divide throughout by 3 to simplify :
- 1/3 x (3x² - 24x + 12)
- x² - 8x + 4
Using the Quadratic Formula :
- x = -b ± √b² - 4ac / 2a
- x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
- x = 8 ± √64 - 16 / 2
- x = 8 ± √48 / 2
- x = 8 ± 4√3 / 2
- x = 4 ± 2√3
Factors are :
- <u>[x - (4 + 2√3)] and [x - (4 - 2√3)]</u>
Answer:
First do 6+7 (PEMDAS), plus 2 and then plus 54
2+(-11) is -9
Dividing means you subtract the exponents. Dividing by a number is the same as changing the sign on the exponent.
x⁰/x² = x⁻² = 1/x²
y⁻³/y⁻¹ = y⁻³⁻⁻¹ = y⁻² = 1/y²
together is 1/x²y², answer B
Answer:
Step-by-step explanation:Because many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.
