Step-by-step explanation:

1-

(9 - 2) ^{2}  - (2 ^{2}  - 3 ^{2} ) + 2

calculate the powers behind the brackets from left to right

2-

(49) ^  - (4 - 9 ) + 2

Calculate the powers (a power squared means the number times itself so 2 squared equals 4)

3-

49 - - 5+2

Calculate the sum ( minus minus equals plus so for example 4- -5= 4+5=9)

4- 49+5+2= 56

Answer: 56

Step-by-step explanation:

First we have to do whats in the parenthesis/ brackets, so lets rewrite the equation after we solve them.

(7)^2 - [4-9] + 2

We can simplify this even further

49 - [-5] + 2

54 + 2

56

For the function Y=5x, what would happen if the value 5 was changed to 3
Daniel [21]

Answer:

y = 3 * x

Step-by-step explanation:

We have the function y = 5 * x, they ask us what would happen if we change the 5 by the 3. thus:

y = 3 * x

the constant that accompanies x in this case is an increase or slope constant, that is, now x will not increase by a ratio of 5, but by a ratio of 3. For example:

If x were worth 10

the value before was 50 and now it will be 30.

I do not increase 5 times but 3 times.
