1st use the Step! Please, Excuse, My, Dear, Aunt, Sally! Ehich also means (PEMDAS) Parenthesis (), Exponents ", Multiple ×, Division÷, Addition+, and Subtraction-. Than your going to solve! (3n+5)×9=n×7
27n+45=7n
27n-7n=-45
20n=-45
n=-45/20= -9/4

What are the approximate solutions of 2x2 − 7x = 3 rounded to the nearest hundredth?. . No real solutions. . x ≈ −0.77 and x ≈ 7
horrorfan [7]
 The solution to the problem is as follows:

2x² - 7x = 3 can be re-written as 2x² - 7x - 3 = 0 
<span>
Either by completing the square or using the quadratic formula this can be solved . </span>
<span>
Let's complete the square. </span>
<span>
2x² - 7x - 3 = 2(x² - 3.5x - 1.5) = 2(x - 1.75)² - 9.125....then we can put </span>
2(x - 1.75)² = 9.125 : (x - 1.75)² = 9.125/2 = 4.5625 
x - 1.75 = √4.5625 ≈ ± 2.14 
<span>x = 1.75 ± 2.14 .....thus x ≈ 3.89 and x ≈ - 0.39
</span>

The exponential function that represents the table is y =2\times 2^x

<h3>What is an exponential function?</h3>

An exponential function is any function that has its constant raised to the power of an argument.

An exponential function is represented as:

y = ab^x

Where:

  • a represents the initial value
  • b represents the rate

From the table we have the following ordered pair

(x,y) = {(0,2) (1,8)}

So, we have:

y = ab^x

2 = a \times b^0

a = 2

Also, we have:

y = ab^x

8 = 2 \times b^1

8 = 2 \times b

Divide both sides by 2

b =4

So, we have:

y = ab^x

y =2\times 2^x

Hence, the exponential function is:

y =2\times 2^x

These two Scalene triangles are similar with a scale of 5:2. What is true about these figures?
Ostrovityanka [42]

Answer:AC/DF =5/2

Step-by-step explanation: since triangle ABC and triangle DEF have a scale of 5/2 the side from the bigger triangle (ABC) would be 5 and the smaller triangle (DEF) would be 2.
