Answer: x = 9
Step-by-step explanation:
Step 1: Add 3 to both sides.
2x − 3 + 3 = 15 + 3
2x = 18
Step 2: Divide both sides by 2.
2x/2 = 18/2
x = 9
(2/5)^8 x (2/5)^-2 / (5/2)^-7
The required answer is ⅖¹³.
Step-by-step explanation:Given terms to us is :-
[tex]=\bf \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7}[/tex]
We can see here that two terms have same base that is ⅖ . And the other is 5/2. So for simplifing the expression we will use some laws of exponents , which are :-
a ^m + aⁿ = a^{m + n }a -ⁿ = ( 1/a )ⁿUsing these we have ,
[tex]\bf = \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{5}{2}^{-7} \\\\\bf= \dfrac{2}{5}^8 \times \dfrac{2}{5}^{-2}\times \dfrac{2}{5}^7 \\\\\bf= \bigg(\dfrac{2}{5}\bigg)^{(8+7-2)}\\\\\boxed{\red{\bf= \dfrac{2}{5}^{13}}}[/tex]

Step-by-step explanation:
You would basically just do the problem from left to right
(102-398) first
Then the answer you get (64) times 14
Then that answer (896) and divide it by 7 and get 128.
After that you do 128+162 and get 290

PLEASEEEE HELPP!!!! PLEASEE HELP NOW PLEASE!!
Answer:
7.19
Step-by-step explanation:
Answer
$7.20 if you round up. Not rounded is $7.198 or just $7.19
Step-by-step explanation
First, get original price which is $9 rounded.
Then, multiple by percent off which would be .20 or .2. Don't get this confused with 2% off which is .02.
After multiplying, you should get the answer of $1.80, this is 20% of $9.00. So if the product was 20% off, you would subtract. This gives you the final answer of $7.20
A thanks or good rating would be greatly appreciated :D

2. It is not a function since for input '4', there are two different outputs.
3. No, the graph does not represent a function. For x > -3, there are two different corresponding values of y on the graph.
Consider the following quadratic equation. f(x) = 9x^2
Part A: Write a function, g(x), the shifts f(x) down by 3 units.
Part B: Write a function, h(x), that vertically stretches f(x) by 6 units.
Part C: Write a function, m(x), that reflects f(x) about the x-axis.
Answer:
[tex]g(x) = 9x^{2} -3[/tex][tex]h(x) = 54x^{2}[/tex][tex]m(x) = -9x^{2}[/tex]Explanation:
[tex]f(x) = a(x-h)^{2} + k[/tex]
a:
Determines direction.Negative x reflects over x-axis.a < 1 --> vertically shrunk.a > 1 --> vertically streched.h:
Determines left and right.Sign of h flips...(x + h) goes left.(x - h) goes right.k:

Find the missing right triangle side lengths in the models of the Pythagorean Theorem below
Answer: 24, 10, 26 and 4.6, 5, 6.7
Step-by-step explanation: for the first triangle the square with the area 576 has side lengths of 24 because 24 is the square root of 576, the square with the area 676 has a side length of 26 because 26 is the square root of 576, and we already know the side lengths of the third triangle are 10 for the second triange we know the side length of the square with the area 21 is about 4.6 because √21 ≈ 4.6 and the square with the area 25 the side length is 5 because √25 = 5 and the last square the side length is 6.7 because √46 ≈ 6.7
