Answer:

No x-intercept/Zero

Step-by-step explanation:

f(x)=3x(3/4)x-4

To find x-intercept/zero, substitute f(x)=0

0=3x(3/4)x-4

To raise a fraction to a power, raise the numerator and denominator to that power

0=3x 3 x-4/4 x-4

Calculate the product

0=3 x-3/4 x-4

Since the right-hand side is always positive, the statement is false for any value of x

Since there is no solution for f(x)=0, there is no x-intercept/Zero

Vince needed five eights of a package of marbles for each gift bag if he had to make five gift bags how many packages of marbles

Alenkasestr [34]

Answer:

$3\frac{1}{8}$ packages of marbles.

Step-by-step explanation:

We have been given that Vince needed five eights of a package of marbles for each gift bag. He had to make five gift bags. We are asked to find the number of packages of marbles that Vince needs.

To find the number of packages that Vince needs, we will multiply package needed for each gift with total number of gift packages.

$\text{Number of packages that Vince needs}=\frac{5}{8}\times 5$

$\text{Number of packages that Vince needs}=\frac{5\times 5}{8}$

$\text{Number of packages that Vince needs}=\frac{25}{8}$

$\text{Number of packages that Vince needs}=3\frac{1}{8}$

Therefore, Vince needs $3\frac{1}{8}$ packages of marbles.

The length of a rectangle is 5cm more than width. Find expression fo the perimeter of the rectangle in terms of the w

galina1969 [7]

Answer:

Perimeter $=4w+10$

Step-by-step explanation:

Let $w$ = width of the rectangle.

From the information "length of a rectangle is 5cm more than width", we can write:

Length = $w+5$

- - - -

Perimeter $= 2l+2w$ (formula for the perimeter of a rectangle)

$=2(w+5)+2w$

$=2w+10 + 2w$

$=4w+10$

∴ The expression of the perimeter of the rectangle in terms of $w$ is $4w+10$ .

Hope this helps :)
