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
8000/ 2 = x/16
cross multiply
2x = 8000 * 16
2x = 128000
x = 128000/2
x = 64000 crocus flowers
Answer:
A. 1.4 times more
Step-by-step explanation:
In this kind of exponential function, you multiply by a factor. In this case that factor is 1.4.
Please see the attachment.
Answer: See the figure attached.
Step-by-step explanation:
Observe the figure attached. The vertices of the triangle ABC have the following coordinates:
A(2,5); B(6,2) and C(3,-5)
To graph the image (in this case we can identify it as A'B'C'), you must use the rule
→
.
Then, you have to subtract 6 units from the x-coordinate of each vertex and subtract 4 units from the y-coordinate of each vertex.
Therefore, you get:
Vertex A'→ ![(2-6,5-4)=(-4,1)](https://tex.z-dn.net/?f=%282-6%2C5-4%29%3D%28-4%2C1%29)
Vertex B'→ ![(6-6,2-4)=(0,-2)](https://tex.z-dn.net/?f=%286-6%2C2-4%29%3D%280%2C-2%29)
Vertex C'→ ![(3-6,-5-4)=(-3,-9)](https://tex.z-dn.net/?f=%283-6%2C-5-4%29%3D%28-3%2C-9%29)
Having the vertices of the image A'B'C', you can graph it (See the figure attached).
I believe the answer would be c
