Answer:

1st Option.

Step-by-step explanation:

f(0) = g(0) is correct because both f(0) = -2 and g(0) = -2; they both intersect at that point and therefore the y-value is the same.

The other answer choices don't work because the y-value outputs don't match each other.

Chester Boles reviewed his credit card's monthly statement. It shows a $2,376.10 previous balance and this month's new purchases

ss7ja [257]

Initial balance, I = $2376.10 .

Total amount of purchase made, A = $( 875.22+65.75+45.22+21.23 ) = $1007.42 .

Total amount credit, c = $875.22 .

Fine, f = $45.30 .

Another purchase, $a=\dfrac{2376.10\times 2.5}{100}=\$ 59.4025$ .

So, balance left is :

B = I - A - f - a + c

B = 2376.10 - 1007.42 - 45.30 - 59.4025 + 875.22

B = $2139.1975

Hence, this is the required solution.

(14-3x)2 simplified using the distributive property.

ivolga24 [154]

Answer: 28-6x

This is the same as -6x+28

===============================

To get that answer, you multiply each term inside the parenthesis by the outer term 2

14 * 2 = 28

-3x * 2 = -6x

So,

(14-3x)*2 = 14*2 - 3x*2 = 28-6x

----------

The distribution rule says

a(b-c) = ab-ac

which is the same as saying

(b-c)a = ba-ca

We can flip things around because we can multiply in any order.

Help with this math question

Ulleksa [173]

Answer:

$-\frac{13\sqrt{x} }{x}$

Step-by-step explanation:

We have been given the following expression;

-13/√x

In order to rationalize the denominator, we multiply the numerator and the denominator by √x;

$-\frac{13}{\sqrt{x}}=-\frac{13\sqrt{x} }{\sqrt{x}\sqrt{x}}\\ \\-\frac{13\sqrt{x} }{\sqrt{x^{2} } }\\\\-\frac{13\sqrt{x} }{x}$

Rewrite as a simplified fraction.

Mnenie [13.5K]

Answer:

$\bold{x = \dfrac{8}{9}}$

Step-by-step explanation:

We have to rewrite the below as simplified fraction.

$\large{0.\overline{8} = {?}}$

Solution:

Let $x =0.\overline 8$ which means $x =0.888888.......$

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite $x$ as:

$x =0.8\overline8$ ......(1)

Now, let us multiply the above with 10.

$10x = 0.8\overline 8 \times 10\\\Rightarrow 10 x= 8.\overline8$ ....... (2)

Now, let us subtract (1) from (2):

$10x-x=8.\overline8 - 0.\overline8\\\Rightarrow 9x = 8\\\Rightarrow \bold{x = \dfrac{8}{9}}$

So, in simplified fractions:

$\large{0.\overline{8} = \bold{\dfrac{8}{9}}}$
