YALL HELP plz give me a fraction problem that contains division and multiplication !!

Luba_88 [7]

Answer:

This one is a bit easy, so if you need a harder one, just let me know.

((32/48) x (4/6)) / (2/5)

Step-by-step explanation:

1) You can simplify both (32/48) and (4/6) to (2/3).

2) Multiply (2/3) by itself, giving (4/9).

3) Dividing by a fraction is equivalent to multiplying by its reciprocal, or opposite. In this example, the reciprocal of (2/5) is (5/2). Thus, (4/9) x (5/2) = (20/18).

4) Simplify your answer, to (10/9) or 1 and 1/9 (as a mixed fraction).

Consider the quadratic function:

Mice21 [21]

Answer:

vertex is (4,-25)

Step-by-step explanation:

$f(x) = x^2 - 8x - 9$

To find out the vertex we use formula

$x=\frac{-b}{2a}$

From the given f(x), the value of a=1, b=-8 and c=-9

Plug in the values in the formula

$x=\frac{-(-8)}{2(1)}$

x=4

Now find the value of y

plug in 4 for x in f(x)

$f(4) = 4^2 - 8(4)- 9=-25$

The value of y is -25

The vertex is (4,-25)

A rectangle has a length of x and a width of 5x^3+4-x^2. What is the polynomial that models the perimeter of the rectangle

sveticcg [70]

Answer:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

$P= 2L +2W$

And replacing we got:

$P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2$

And symplifying we got:

$P(x)= 10x^3 -2x^2 +2x+8$

Step-by-step explanation:

For this problem we know that the lenght of the rectangle is given by:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

$P= 2L +2W$

And replacing we got:

$P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2$

Identify an equation in slope-intercept from for the line parallel to y=-3x + 7 that passes through (2, -4)

alexandr1967 [171]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

The parallel lines have the same slope.

We have y = -3x + 7 → m = -3. Therefore y = -3x + b.

Put the coordinates of the point (2, -4) to the equation of a line:

$-4=-3(2)+b$

$-4=-6+b$ add 6 to both sides

$2=b\to b=2$

<h3>Answer: y = -3x + 2</h3>
