L = large pumpkin
m = medium pumpkin
Write a system of equations:
1) L + m = 20
2) m = L - 6
3) $3L + $2m = $53
Substitute L - 6 for m in equation 1:
L + (L - 6) = 20
Add 6 to both sides:
2L = 26
(L + L = 2L)
Divide two on both sides:
L = 13
Julie bought 13 large pumpkins.
Check (use equation 3):
$3(13) + $2(7) = 53
(m = 7 because 20 - 13 = 7)
Multiply:
$39 + $14 = $53 :)
Range bar graphs represents the dependent variable as interval data. The bars rather than starting at a common zero point, begin at first dependent variable value for that particular bar. Just as with simple bar graphs, range bar graphs can be either horizontal or vertica
Answer:
-5
Step-by-step explanation:
First, distribute the 2 to the 3, -9, and 5. You will get 6 + 6 - 18 + 10 + (-9). Then, you can start from the beginning and work through combining the terms. The original equation is in bold after every step.
6 + 6 - 18 + 10 + (-9)
6+6 = 12
12 - 18 + 10 + (-9)
12-18 = -6
- 6 + 10 + (-9)
-6 + 10 = 4
4 + (-9)
4 - 9 = -5
Answer: -5
The domain and the range of an <em>exponential parent</em> function, that is, y = eˣ are equal to all <em>real</em> numbers and <em>non-negative</em> numbers, respectively. (Correct choice: C)
<h3>How to determine the domain and range of an exponential function</h3>
In this problem we should determine what an <em>exponential parent</em> function is. The most common <em>exponential</em> functions have the following form:
(1)
(1) is an <em>exponential parent</em> function for A = 1, B = 1 and C = 0.
All functions are relations with a domain and range, the domain is an <em>input</em> set related to the range, that is, an <em>output</em> set. In the case of an <em>exponential parent</em> function, the domain and the range of the expression are 
and y ≥ 0, respectively. (Correct choice: C)
