No, the coordinates doesn’t make the equation a true statement, therefore it can’t be a solution.

A problem states that Ursala earns $9 per hour to write an expression that tells how much money ursala earns for h hours joshua

kap26 [50]

Sarah's expression is correct because for every hour you get 9 dollars so 9(1) is 9 dollars for one hour. Then for two Hours it would be 9(2) which equals 18.

HELP ASAP PLEASE AND SHOW WORK!!! Write the vertex form of the following equation. y= x^2+6x-5

valkas [14]

Answer:

<h3> $\boxed{\bold{y=(x+3)^2-14}}$ </h3>

Step-by-step explanation:

y= x²+6x-5

completing the square: a²+2ab+b² = (a+b)² where a²=x² (so a=x) and 2ab=6x (so b would be 3):

$y=x^2+6x-5\\\\y=\underline{x^2+2\cdot x\cdot3+3^2}-3^2-5\\\\y=(x+3)^2-9-5\\\\\underline{y=(x+3)^2-14}\\\\\\vertex:\ \ (-3,\,-14)$

Nine less than three times a number is greater than forty

pentagon [3]

Start with an equation.
Nine less... so -9
3 times a number = 3x
Greater than 40 is >40

So put together is 3x-9>40
When solving I imaging the greater than sign as an equal sign. Less confusing.
3x-9=40
3x=49
x>49/3
