Answer:
y = -1/4x - 2
Step-by-step explanation:
Since the line has to be perpendicular, that means the new slope multiplied by the original should be -1. The original slope is 4, so the new one would be -1/4. Now our equation is y = -1/4x + z, z being the y intercept. We can find this by substituting the point in and finding the match. 1= -1/4(-12) + z. z has to equal -2, so the answer is y = -1/4x - 2
-6^2 - 28/4 + (-9)
Multiply -6 by it's exponent.
36 - 28/4 + (-9)
Divide 28 by 4
36 - 7 + (-9)
Subtract 7 from 36.
29 + (-9)
Add -9 to 29. This would be the same as subtracting 9 from 29(29-9).
Final Answer: 20
Answer:
the solution is 4.5
Step-by-step explanation:
The weight of the kitten will be no less than the weight of the puppy in 1.4 + 1.2x ≥ 2.8 + 0.5x week.
<h3>What is Inequality?</h3>
Statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.
Given:
A puppy weighs 2.8 pounds at birth and gained about 0.5 pounds per week.
A kitten weighs 1.4 pounds at birth and gains about 1.2 pounds per week.
puppy: 2.8 + 0.5x
Kitten: 1.4 + 1.2x
As, kitten is no less than puppy.
Kitten ≥ puppy
1.4 + 1.2x ≥ 2.8 + 0.5x
hence, the weight of the kitten will be no less than the weight of the puppy in 1.4 + 1.2x ≥ 2.8 + 0.5x week.
