F(x) = ax + b
f(x) = 5x - 2
So: a =5
tg α = a
tg α = 5
α ≈ 78,5 °
Answer:
<u>The length of the rectangle is 16 feet, the width of the rectangle is 8 feet.</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
Length of the rectangle = x
Width of the rectangle = x/2 ( half as long as the length)
Area of the rectangle = 128 square feet
2. Let's find the value of the length and the width
Area of the rectangle = Length of the rectangle * Width of the rectangle
128 = x * x/2
128 = x² /2 (x * x = x²)
256 = x² (Multiplying by 2 to both sides of the equation)
x² = 256
√x² = √ 256
<u>x = 16</u>
<u>The length of the rectangle is 16 feet.</u>
<u>Width of the rectangle = x/2 = 16/2 = 8 feet.</u>
<u>The length of the rectangle is 16 feet, the width of the rectangle is 8 feet.</u>
Answer:
- 2 1/10
Step-by-step explanation:
-2/5 -x -9/10
Let x = 4/5
-2/5 - 4/5 - 9/10
Combine like terms
-6/5 - 9/10
Get a common denominator of 10
-6/5 * 2/2 - 9/10
-12/10 - 9/10
-21/ 10
Change this to a mixed number
10 goes into 21 2 times with 1 left over
-2 1/10
Answer:
2
Step-by-step explanation:
{(-6, -4), (4, -8),(-6,9), (1, -3)}
These ordered pairs are not a function.
-6 has 2 outputs.
