For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
The slope is found using the following formula:
According to the graph we have the following points:
Substituting we have:
Therefore, the line is of the form:
We find "b" replacing the coordinate "y" of a point:
Thus, the equation is:
Answer:
Answer:
$32.6
Step-by-step explanation:
$5.20 x 3 = $15.6
$4.90 x 4 = $19.6
$19.6 + $15.6 = $35.2
Answer:
Equation: y = x²
Equation: f(x) = 2(x + 1)² - 1
Step-by-step explanation:
Equation: y = x²
- when x = -2, y = (-2)² = 4 ⇒ (-2, 4)
- when x = 0, y = (0)² = 0 ⇒ (0, 0)
- when x = 2, y = (2)² = 4 ⇒ (2, 4)
Equation: f(x) = 2(x + 1)² - 1
f(-2) = 2(-2 + 1)² - 1
= 2(-1)² - 1
=2(1) - 1
= 1
Therefore, (-2, 1)
f(0) = 2(0 + 1)² - 1
= 2(1)² - 1
=2(1) - 1
= 1
Therefore, (0, 1)
f(2) = 2(2 + 1)² - 1
= 2(3)² - 1
=2(9) - 1
= 17
Therefore, (2, 17)
I would take the 82 cm and then divide it by the 1 stay with me.Then you will take the answer of that part and then you will use the parcile products of that problem and then boom you have your answer!
Hope this helps!;)
