Answer:
first option
Step-by-step explanation:
Given
y = 2(x - 3)² + 1
Rearrange making x the subject
Subtract 1 from both sides
y - 1 = 2(x - 3)² ( divide both sides by 2 )
= (x - 3)² ( take the square root of both sides )
± = x - 3 ( add 3 to both sides )
± + 3 = x
Change y into terms of x with x being the inverse, that is
(x) = ± + 3
Answer:
$2.37
Step-by-step explanation:
if you 13 from 32 and then divide that by 8 you get 2 dollars and 37 cents
Answer:
x = 1
Step-by-step explanation:
8 -(x+5) = 5x - 3
-(x+5) ---> -1 (x +5) = -x - 5
8 - x - 5 = 5x -3 8 - 5 = 3
-x + 3 = 5x - 3
+x +x
3 = 6x - 3
+3 +3
6 = 6x
/6 /6
<u>x = 1</u>
Answer:
-3/2x + y = 11
Step-by-step explanation:
Standard Form of an equation is written typically like this: Ax + By = C
If that's the case, we have to get all the x's and y's to the same side.
Here's how I do it:
y - 5 = 3/2(x + 4) Distribute the 3/2 to the terms in the parenthesis.
y - 5 = 3/2x + 6 Subtract 3/2x from both sides
y - 5 - 3/2x = 6 Add 5 to both sides
y - 3/2x = 6 + 5 Rearranging and simplifying terms.
Ax + By = C --> -3/2x + (1)y = 11
