Answer: i took the test and got it right
D (0.55,0.75)
Step-by-step explanation:
Given:
The ratio of red and blue cubes is 4:7.
After adding 10 more red cubes the ratio of red and blue cubes is 6:7.
To find:
The number of blue cubes.
Solution:
The ratio of red and blue cubes is 4:7.
Let the number of red and blue cubes be 4x and 7x respectively.
After adding 10 more red cubes.
Number of red cubes = 4x+10
Then, the ratio of red and blue cubes is 6:7.





Divide both sides by 14.

Now,
Number of blue cubes in the bag is

Therefore, the number of blue cubes is 35.
The answer is 30
because (2)(10) + 10
20+10=30
the 10 came from the m!!
✦ Explanation <span>✦
</span><span>☛ We know that (-1,-3) is the vertex.
</span>☛ Set up the parabola as y = k(x+1)²-3
☛ 1 = k(0+1)²-3
☛ k = 4
☛ y = 4(x+1)²-3 is the equation
