3. Rewrite the expression as simply as you can: 3x + 11y - 2x - 4y

vfiekz [6]

Answer:

x+7y

Step-by-step explanation:

First off, lets split the question into both x and y.

3x - 2x for the x

11y - 4y for the y

You can solve both of them to get x + 7y

3x - 2x = x

11y - 4y = 7y

Then, add them back up and get x + 7y

You are preparing a community garden with your youth group to have enough room for the spots for all the people who already sign

Annette [7]

Answer:

92 feet.

Step-by-step explanation:

Given:

The length of the garden needs to be 22 feet longer than the width of the garden.

The perimeter of the fence is a total of 324 feet

Question asked:

What will the length be of garden ?

Solution:

As length of the garden needs to be 22 feet longer than the width,

Let width = $x$

Then, length will be = $x+22$

As here perimeter of the fence is given, we can find length and width of garden by using:

Perimeter of rectangle = $2(length+width)$

$324=2(x+22+x)\\324=2(2x+22)\\324=4x+44\\$

Subtracting both sides by 44

$324-44=4x+44-44\\280=4x\\$

Dividing both sides by 4

$70=x$

Width = $x$ = 70 feet

Then, length will be = $x+22$ = 70 + 22 = 92 feet

Therefore, the length of the garden will be 92 feet.

When you find f(2) for a given function f, you are finding the y value associated with x= 2

sveticcg [70]

Answer:

The provided statement is TRUE.

Step-by-step explanation:

The function f is an expression in variable x.

The entire expression can either be denoted by f (x) or y.

For instance consider the quadratic expression:

f (x) = ax² + bx + c

≡ y = ax² + bx + c

So, on computing the value of f (2), it implies that we are computing the value of y for x = 2.

Thus, the provided statement is TRUE.
