PLEASE HELP! Explain your answer, THANK YOU!

Misha Larkins [42]

Answer:

-2/-3

Step-by-step explanation:

(75, 60) (45, 40)

75 60 since 75 is larger than 45, we subtract = -30

45 40 since 60 is larger than 40, we subtract = -20

= -20/-30

reduce

= -2/-3

2x²-5x-12=0 (simplify solution set)

Arada [10]

Answer:

x = 4 or x = -3/2

Step-by-step explanation:

To simplify and solve this, let's use the quadratic formula.

So the format of a quadratic equation is supposed look like this:

$ax^2+bx+c=0$

Let's find a, b, c:

a is the coefficient of x^2
b is the coefficient of x
c is the constant term

Now let's solve the equation.

Let's solve your equation step-by-step.

2x^2−5x−12=0

For this equation: a=2, b=-5, c=-12

2x^2+−5x+−12=0

Step 1: Use quadratic formula with a=2, b=-5, c=-12.

$x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

$x=\frac{-(-5)\pm\sqrt{(-5)^2-4(2)(-12)} }{2(2)}$

$x=\frac{5\pm\sqrt{121} }{4}$

$x=4$ or $x=\frac{-3}{2}$

<u>Answer:</u>

x = 4 or x = -3/2

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 8% each week. The following function represents t

dybincka [34]

The function is f(x) = 86(1.01)^7x; grows approximately at a rate of 1% daily

<h3>How to rewrite the function?</h3>

The function is given as:

f(x) = 86(1.08)^x

There are 7 days in a week.

This means that:

1 day = 1/7 week

So, x days is

x day = x/7 week

Substitute x/7 for x in

f(x) = 86(1.08)^(x/7)

Rewrite as:

f(x) = 86(1.08^1/7)^x

Evaluate

f(x) = 86(1.01)^x

In the above, we have:

r = 1.01 - 1

Evaluate

r = 0.01

Express as percentage

r = 1%

Hence, the function is f(x) = 86(1.01)^7x; grows approximately at a rate of 1% daily

A rectangular garden has an area of 24 square meters. The width is 8 meters less than twice the length. Find the dimensions of t

OLEGan [10]

Answer:

Length: 6 m

Width: 4 m

Step-by-step explanation:

Area: 24 $m^{2}$

Width: 2L - 8 m

Length: ?

Formula: A = W * L

Replace the variables:

24 = (2L - 8) * L

24 = 2 $L^{2}$ - 8L

0 = 2 $L^{2}$ - 8L - 24

or

2 $L^{2}$ - 8L - 24 = 0

Solve; if you don't know how to solve it using this method, let me know. It's the expression $Ax^{2} +Bx+C$

1. $2 (\frac{(2L^2 - 8L - 24)}{2})$

2. $\frac{(2L)^2 - 8(2L) - 48}{2}$

3. $\frac{(2L - 12)(2L + 4)}{2}$

4. $2(\frac{(L - 6)(2L + 4)}{2})$

5. (L-6) (2L+4)

6. L-6 = 0 AND 2L+4 = 0

L - 6 =0

L = 6

---------------------------------

2L = -4

L = $\frac{-4}{2}$

L = -2

Since the length cannot be negative, the only real value is 6.

Area: 24 $m^{2}$

Width: 2L - 8 m

Length: 6 m

Calculate width:

W = 2L - 8

W = 2(6) - 8

W = 12 - 8

W = 4 m
