For a red marble you have 4 points and a blue you have 7, therefore the R(number of red marble) and B( blue marbles)
the answer is gonna be :{4r+7b}
Hope this help
Answer:
-2
Step-by-step explanation:
2(x+3)=2
Divide both sides by 2:
x+3=1
Subtract 3 from both sides:
x=-2
Hope this helps!
Ratio of 2 complementary angles = 4:5
Let first angle be 4x
Let second angle be 5x
Sum of two complementary angles = 90
4x + 5x = 90
9x = 90
x = 90/9 = 10
First angle = 4x = 4*10 = 40
Second angle = 5x = 5*10 = 50
I hope it is helpful...
The first thing you should do is use the fact that the area of the triangle is:
A = b * h * (1/2).
From there you clear the height as a function of "c"
Then you will have a polynomial division which you must make to find the height of the triangle.
I attach the solution.
Answer:
Domain: all reals
Range: 4 ≤y <∞
Step-by-step explanation:
The domain is the possible input values(x)
From the arrows at the left and right ends on the graph, the inputs can be all reals
The range is the possible output values (y)
Y goes from 4 to infinity
4 ≤y <∞
