Answer:
B(-10)=-6
Step-by-step explanation:
we have
B(x)=x+4
we know that
B(-10) is the value of the function B(x) for the value of x=-10
so
substitute the value of x=-10 in the function
B(-10)=-10+4=-6
therefore
B(-10)=-6
Answer:
![y> \frac{2x}{3} -7](https://tex.z-dn.net/?f=y%3E%20%5Cfrac%7B2x%7D%7B3%7D%20-7)
Step-by-step explanation:
The equation of the straight line passing through the points (0,-7) and (3,-5) will be
⇒
⇒
......... (1).
Now, the inequality shades the upper portion of the straight line.
Therefore, the y value for the inequality will be more than y value for the equation corresponding to a fixed value of x.
Hence, the inequality equation will be

Answer:
Correct choice is A
Step-by-step explanation:
Natalia bought 30 kg of apples that cost 75 zl. Then
of apples costed
![\dfrac{2}{5}\cdot 75=2\cdot 15=30\ zl.](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%2075%3D2%5Ccdot%2015%3D30%5C%20zl.)
Natalia bought 16 kg of cucumbers that cost 104 zl. Then
of cucmbers costed
![\dfrac{2}{5}\cdot 104=2\cdot 20.8=41.6\ zl.](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B5%7D%5Ccdot%20104%3D2%5Ccdot%2020.8%3D41.6%5C%20zl.)
Then the total cost is
![30+41.6=71.6\ zl.=71\ zl\ 60\ gr.](https://tex.z-dn.net/?f=30%2B41.6%3D71.6%5C%20zl.%3D71%5C%20zl%5C%2060%5C%20gr.)
