Answer:
josh vendió 17 libros recaudando 306 dolares .
jessica vendió 255 libros recaudando 4590 dolares.
Step-by-step explanation:
Sustituimos por variables :
libros que vendió Jessica = x
libros que vendió Josh = y
entonces:
x + y = 272
Jessica vendió 15 veces mas libros que josh:
x = 15y
Reemplazamos en la anteriior ecuacion:
15y +y = 272
16y = 272
y = 17
Reemplazamos en la primela ecuacion :
x + 17 = 272
x = 255
Answer:
infinite solutions
Step-by-step explanation:
3x+15=3(x+5)
distribute
3x+15=3x+15
infinite solutions
So prime factorization is what it seems, <u>finding the prime factors of a number.</u> Using prime factorization, we can break down 254 as such:
Since 2 and 127 are prime,<u> the prime factorization of 254 is 2 × 127.</u>
Answer:
Correct answer: sa · sb = 2/3 · (- 3/2) = - 1
Step-by-step explanation:
Given:
line A - (x₁, y₁) = (3, -4) and (x₂, y₂) = (6, -2)
line B - (x₁, y₁) = (-1, 5) and (x₂, y₂) = (1, 2)
The slope is calculated using the following formula:
s = (y₂ - y₁) / (x₂ - x₁)
sa = (-2 - (-4)) / (6 - 3) = (-2 + 4) / 3 = 2 / 3
sa = 2 / 3
sb = (2 - 5) / (1 - (-1)) = -3 / 2
when lines are perpendicular to each other then the slopes are in the next relationship:
sa · sb = - 1
we will check:
sa · sb = 2/3 · (- 3/2) = - 1
