Answer:
Step-by-step explanation:
1) Reagrupar términos.
3(5x + 1) = 15x^3
2) Divide ambos lados por tres.
5x + 1 = 5x^3
3) Mueva todos los términos a un lado.
5x + 1 - 5x^3 = 0
4) No se encontró ninguna raíz algebraicamente. Sin embargo, las siguientes raíces se encontraron por métodos numéricos.
x=−0.878886,−0.209148,1.088033
73
73 * 19 = 1,387
Hope I helped you!
Answer:
Step-by-step explanation:
Pythagorean theorem is:
If we have two points;
A(x₁,y₁)
B(x₂,y₂)
m=slope
m=(y₂-y₁) / (x₂-x₁)
Therefore:
(6,7)
(9,2)
m=(2-7) / (9-6)=-5/3.
Solution₁= the solpe of the line that passes through the poitns (6,7) and (9,2) is m=-5/3.
(17,9)
(5,29)
m=(29-9) / (5-17)=20/-12=-5/3
Solution ₂: the slope of the line that passes through the parir of points (17,9) and (5,29) is m=-5/3
Therefore, both lines have the same slope.
Answer:
448.23
Step-by-step explanation:
Sales tax is addition to the original price
The original price is 100%
First we find 1% of this, which is 415.99 / 100 = 4.1599
Then multiply this by 7.75 = 32.239225
Add this to the original price = 415.99 + 32.239225 = 448.229225
You have to round this to an appropriate number as the question uses two decimal places I think this will suffice = 448.23
