Answers

Answer 1

Answer:

x-6y+4z

Step-by-step explanation:

8x+y-9x+3z+2x-7y+z

Answer 2
8x+y-9x+3z+2x-7y+z

So first you wanna group the ones that are the same so 8x-9x+2x so that will give you 1x

Then you do y-7y then that gives you -6y

Then you do 3z+z and that gives you 4z


So the answers is 1x-6y+4z

Evaluate the expression y2 when y=2.5

Answers

Answer:

5

Step-by-step explanation:

if u wouldnt mind giving me brainliest, just tryna rank up

The value of the expression at y = 2.5 is 6.25.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

y²

Substitute y = 2.5

= y²

= 2.5²

= 2.5 x 2.5

= 6.25

Thus,

The value is 6.25.

Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.

Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?

Select one:
A. f(x)=(34)^(x)+9
B. f(x)=0.45(1.9)^(x)
C. f(x)=(65)^(x)−6
