Answer:
a = -5
Step-by-step explanation:
negative (5 minus (a + 1)) = 9 minus (5 minus (2a minus 3)) can be expressed mathematically as follows.
- (5 - (a + 1)) = 9 - (5 - (2a - 3))
using the principle of PEMDAS, all the parenthesis values are first solved
- (5 - a - 1) = 9 - (5 - 2a + 3)
-5 + a + 1 = 9 - 5 + 2a - 3
collect like terms
-5 + 1 - 9 + 5 + 3 = 2a - a
-5 = a Therefore,
a = -5
A. Erica gets 6 dollars per hour.
B. She would get 48 dollars for 8 hours.
C. I would say 5 and a half hours. Maybe 5 hours and 45 minutes.
Answer:
<em>please see attached image</em>
Step-by-step explanation:
This function's graph can be achieved by plugging in different coordinates. Because this can be time consuming, just have a graph provided by Desmos for reference(see attachment)
The line slightly to the right has no y-intercept and an x-intercept of (2.732, 0).
The line slightly to the left has an y-intercept of (0,1), and an x-intercept of (-2,732, 0)
From the graph, we can determine this function has multiple solutions.
Hope this helps!
Answer:
A and D and E
Step-by-step explanation:
Substitute the variable(in this case) <em>t</em> for 3, then use the order of operations to simplify(PEMDAS), which will give you 33 for both expressions. To see if two expressions are equivalent, you need to substitute the variable for an odd number AND an even number, so next, substitute the variable <em>t </em>for the number 6, which will give you 51 for both expressions. That means the expressions are equivalent
Hope this helps :)
