Zero-Exponent Rule: a0 = 1, this says that anything raised to the zero power is 1. ... Negative Exponent Rule: , this says that negative exponents in the numerator get moved to the denominator and become positive exponents. Negative exponents in the denominator get moved to the numerator and become positive exponents.
Answer:
<h2>
y = -¹/₄x - 1</h2>
Step-by-step explanation:
If two lines are perpendicular then the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 4x - 2 ⇒ m₁=4
4×m₂ = -1 ⇒ m₂ = -¹/₄
The line y=-¹/₄x+b passes through point (4, -2) so the equation:
-2 = -¹/₄×4 + b must be true
-2 = -1 + b
b = -1
Therefore equation in slope-intercept form:
y = -¹/₄x - 1

<u>Answer:</u>
- In 8 hours, Michael can drive 48 miles.
<u>Step-by-step explanation:</u>
<u>Let's write our equation.</u>
- 30 miles = 5 hours
- => 30/5 miles = 1 hour
- => 6 miles = 1 hour
- => 6 x 8 miles = 1 x 8 hours
- => 48 miles = 8 hours
Hence, <u>in 8 hours, Michael can drive 48 miles.</u>
Hoped this helped.
Answer:
A rectangle doesn't has a diameter
________________________________
But if you are asking about perimeter.
Step-by-step explanation:
Perimeter = 2(l + b)
l = 9cm
b = 5cm
Perimeter = 2(l + b)
= 2(9 + 5)
= 18 + 10
= 28cm
