x+1
Step-by-step explanation:
3x -(2x+4)+5
3x-2x-4+5
[3x-2x]+[-4+5]
x+1
Your answer is D for your purposes
Work:
Multiply b and 5
Multiply b and 1
The b just gets copied along.
5*b evaluates to 5b
Multiply b and 6
Multiply b and 1
6*b evaluates to 6b
6*b-10 evaluates to 6b-10
Multiply 5b by 6b-10
Multiply 5b by each term in 6b-10 term by term.
This is the distributive property of multiplication.
Multiply 5b and 6b
Multiply the b and b
Multiply b and b
Combine the b and b by adding the exponents, and keeping the b, to get b²
5b × 6b =
Multiply 5b and -10
Multiply b and 1
5b × -10 = -50b
5*b*(6*b-10)
***The final answer is 30b²-50b***
Answer:
The given function is
Which is a parabola concave down with vertex at the origin of the coordinate system.
If the width of the arch is 800 feet, that means 400 feet on negative side and 400 feet and positive.
The image attached shows the graph of this parabola, where you can see the points for each extreme of the arch.
Notice that each point of the base of the arch is at y = -200, that means the height of the arc is 200 feet.
Now, the domain for this function is all real numbers. The range for this function is all number least or equal than zero.
Answer:
19/35
Step-by-step explanation:
1/7 + 2/5
you need to make both of the denominators equal. to make them equal, multiple 1/7 by 5 to make 5/35 and multiple 2/5 by 7 to make 14/35.
then add the numerators
5/35 + 14/35 = 19/35
