One of these equations can be simplified to slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

You have 2y = 14 - 2x and y = -x + 7. Divide 2y = 14 - 2x by 2 to get it in slope-intercept form.

(2y)/2 = (14 - 2x)/2
y = 7 - x
y = -x + 7

After dividing 2y = 14 - 2x by 2, we see that the two equations are the same; this means their graphs are the same. Since they share infinitely many points (being the same line), this system of equations has infinitely many solutions.

What is the multiplication and division property of exponets?

Alexandra [31]

Mult
$(x^m)(x^n)=x^{m+n}$

div
$\frac{x^m}{x^n} =x^{m-n}$

baseically, x is the base, and m and n are bases

you can only use this property if bases are same

baseically
multiply means add powers
divide means subtract bottom power from top

Is the product of 3√ and 2.8 is a rational number acquisition?

svetlana [45]

Answer:

It is not rational

Step-by-step explanation:

Given

$\sqrt 3 * 2.8$

Required

Rational or Irrational

$\sqrt 3 * 2.8$

$\sqrt 3 =1.73205$

So, we have:

$\sqrt 3 * 2.8 = 1.73205 * 2.8$

$\sqrt 3 * 2.8 = 4.84974$

<em>The result of the product: 4.84974 is not rational because it can not be represented as a fraction of two integers.</em>

What is a formula for the nth term of the given sequence? 48, 72, 108

WITCHER [35]

Answer:

$a_n=48*1.5^{n-1}$

Step-by-step explanation:

<u>Geometric Sequence</u>

In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

48, 72, 108, ...

The common ratio is found by dividing the second term by the first term:

$r=\frac{72}{48}=1.5$

To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.

Now we are sure this is a geometric sequence, we use the general term formula:

$a_n=a_1*r^{n-1}$

Where a1=48 and r=1.5

$\boxed{a_n=48*1.5^{n-1}}$

For example, to find the 5th term:

$a_5=48*1.5^{5-1}=48*1.5^{4}=243$
