First, you add 36 to both sides to get rid of -36. Then, the right side turns to 44 when add 8 and 36 together. Finally, your final answer is x<44
Answer:
True
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (- 4, - 9), thus
y = a(x + 4)² - 9
To find a substitute the coordinates of the zero (- 7, 0) into the equation.
0 = a(- 7 + 4)² - 9, that is
0 = 9a - 9 ( add 9 to both sides )
9a = 9 ( divide both sides by 9 )
a = 1, thus
y = (x + 4)² - 9 ← expand factor using FOIL
y = x² + 8x + 16 - 9
y = x² + 8x + 7
90% of "a" is 44.......turn ur percent into a decimal...." of " means multiply..." is " means equals...
0.90a = 44...divide both sides by 0.90
a = 44 / 0.90
a = 48.89.....this is rounded
what is 30% of 3a.....and we know that "a" is 48.89...
0.30(3 * 48.89) = 0.30(146.67) = 44 <=== ur answer
The domain of the third piece of the graph is contained in interval <u>B. (12, 20)</u>.
<h3>What is the domain of a graph?</h3>
The domain of a graph consists of all the input values shown on the x-axis.
The input values (domain) are shown on the x-axis, unlike the range, whose output values are shown on the y-axis.
Therefore, the domain comprises the independent variables or values, which can be determined using the function, y = f(x).
Thus, the domain of the third piece of the graph can be determined in interval <u>B. (12, 20)</u>.
