Answer:
2x² + 6 = 34x
Step-by-step explanation:
2x² - 10x + 6 = 24x
Collect like terms
2x² + 6 = 24x + 10x
2x² + 6 = 34x
Answer:
Kendra should have multiplied the x-values by 75 to get the y-values
Step-by-step explanation:
Given
Table
X|| Y
1 || 75
2 || 150
3 || 225
4 || 300
5 || 375
Given that Kendra multiply x by 7.5 to get y
The relationship of x and y can be calculated as thus;
y = rx
Where y and x are the values at the y and x column respectively and r is the constant of proportionality
When y = 75, x = 1.
Plug in these values in the above formula
y = rx becomes
75 = r * 1
75 = r
r = 75
When y = 150, x = 2
150 = r * 2
Multiply both sides by ½
150 * ½ = r * 2 * ½
75 = r
r = 75
When y = 225, x = 3
225 = r * 3
Multiply both sides by ⅓
225 * ⅓ = r * 3 * ⅓
75 = r
r = 75
Notice that r remains 75 and the difference between y values is 75
If you apply these formula on when y = 300 or 375 and when x = 4 or 5, the constant of proportionality will remain The value of 75.
Hence, Kendra mistake is that; Kendra should have multiplied the x-values by 75 to get the y-values
For example, a mix number like 1 ½ basically equals to a whole and a half and in this case the whole would be 2 and the half of 2 is 1. hence, the improper fraction of 1 ½ is 3/2.
15x.25=3.75
15-3.75=11.25.
The answer is $11.25
Answer:
x=5
Step-by-step explanation:
Ok so put them equal to each other
2x+12=3x+7
subtract 12 from both sides
2x=3x-5
subtract 3x from both sides
-x=-5
divide both sides by -1
x=5
