9.2 - B
-2.9 - A
-1.4 - D
4.1 - C
Explanation: the opposite of a number is the same number with the sign flipped
Answer:
60 °F
Step-by-step explanation:
The function can be put into vertex form:
T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms
Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.
T(x) = 0.264(x² -18x +81) +81 -0.264·81
T(x) = 0.264(x -9)² +59.616
The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
Answer:
you have to use the quadratic equation to find the zeros
Step-by-step explanation:
The answer to this question is 0.05
The equation shown on the graph is y = 2x + 3. The correct answer is C. y = 2x +3
<h3>Equation of a line </h3>
From the question, we are to determine the equation that represent the given line
To determine the equation, we will pick two points on the line and determine the equation of the line
Picking the points (0, 3) and (3, 9)
Using the formula for the finding the equation of a line with two given points
(y - y₁)/(x - x₁) = (y₂ - y₁)/(x₂ - x₁)
x₁ = 0
y₁ = 3
x₂ = 3
y₂ = 9
Then,
(y - 3)/(x - 0) = (9 - 3)/(3 - 0)
(y - 3)/x= 6/3
(y - 3)/x= 2
y - 3 = 2x
y = 2x + 3
Hence, the equation shown on the graph is y = 2x + 3. The correct answer is C. y = 2x +3
