Answer:

2

Step-by-step explanation:

The graph in question is a quadratic graph that has been translated by some units, say, a units. In the transformation language, we say that the graph has been stretched by the factor of 2 like this:

y = 2 (x-3)^{2} -1

It means that the graph of x^{2} has been moved by 3 units to the right, stretched by the stretch factor of 2 and moved downwards on y-axis by 1 unit.

Answer:

93°

Step-by-step explanation:

By exterior angle theorem:

(4x + 9)° = 2x° + (3x - 12)°

(4x + 9)° = (2x + 3x - 12)°

(4x + 9)° = (5x - 12)°

4x + 9 = 5x - 12

4x - 5x = - 12 - 9

-x = - 21

x = 21

Measure of exterior angle

= (4x + 9)°

= (4*21 + 9)°

= (84 + 9)°

= 93°

Nina [5.8K]

John has borrowed $6.50 from his friends and $11.75 from his sister. To find how much money he needs to repay you can just add up the amount of money he has borrowed.

Make an equation to solve for this, where x = amount of money John needs to repay. Make the amount of money John borrowed add up to x. Your equation should look like:

$6.50 + $11.75 = x

Combine like terms (add 6.50 and 11.75).

$18.25 = x

After solving the equation, you have figured out that John need to repay $18.25 in total.
