Answer:
80%
Step-by-step explanation:
(54-30)/30 *100 = 80%
D it's store d, it's the cheapest
61 = 3b + 7
3b + 7 = 61
3b = 61 - 7
3b = 54
b = 54/3
b = 18.
Answer:
(-1,-9)
Step-by-step explanation:
(5,-2)
-5 -4 -3 -2 <em><u>-1</u></em> 0 1 2 3 4 <u>5</u>
starting at 5, move 6 units to the left, your new x-coordinate is -1
<u>-2</u>
-3
-4
-5
-6
-7
-8
<em><u>-9</u></em>
starting at -2, move 7 units down, your new y-coordinate is -9
The new point after the translation will be (-1,-9)
Answer:
There are infinite solutions that solve the system
Step-by-step explanation:
- The solution can be expressed as (there are infinite solutions that solve the system). This results from rearranging terms in the first or second equation.
- This is because the first equation is a linear combination of the second one (this is, the first equation equals (-1) times the second equation). This means that the second equation does not add any information about x and y: it says exactly the same as the first equation about the relationship between x and y.
- Then, in terms of solving the system, you have one unique expression (not repeated) that shows the relationship between y and x. This means that, any pair of (x,y) that meet the requirements expressed by , will solve the system. Then we have infinite solutions.
