It would be 7(x+y)
It’s just pulling out the common factors in each set.
Answer:
0.84 kg
Step-by-step explanation:
Given that :
Weight per liter = 1.12kg per liter
That is 1 Litre weighs 1.12 kilogram
The weight of saline solution of 0.75 Litre will be :
1 Litre = 1.12 kg
0.75 Litre = x
Cross multiply :
1 * x = 1.12 * 0.75
x = 0.84 kg
Hence, 0.75 Litre weighs 0.84 kg
Answer:
C
Step-by-step explanation:
y = (x-1) (x+4)
when y=0
x=1 and x= -4
so select C
Answer:
The option d
Step-by-step explanation:
find the intersection with x and y
https://tex.z-dn.net/?f=x%3D0%0A
https://tex.z-dn.net/?f=0%2By%3D-9%20%5Clongrightarrow%20y%3D-9%0A
and https://tex.z-dn.net/?f=y%3D0%0A
https://tex.z-dn.net/?f=x%2B0%3D-9
we get the coordinates
https://tex.z-dn.net/?f=(0%2C-9)%2C%20(-9%2C0)
and the same process for another equation
https://tex.z-dn.net/?f=4*(0)%2By%3D-19%20%5Clongrightarrow%20y%3D-19%5C%5C%0A4*x%2B0%3D-19%20%5Clongrightarrow%20x%3D%5Cfrac%7B-19%7D%7B4%7D%20%5C%5C%5C%5C%0A(0%2C-19)%2C%20(%5Cfrac%7B-19%7D%7B4%7D%2C0)%20
and these coordinates are those expressed in the d graph
Answer: $17.50
Step-by-step explanation:
30 divided by 12 equals 2.5 therefor you would multiply 2.5 by the number of cans purchased, in this case 7.
