1 feet is 12 inches and there is 6 segments in one feet then in 12 feet there is 72 segments
To find the intersection points, you take x^2 - 4x + 9 = -2x + 17
This gives x^2 - 2x - 8 = 0,
which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2
From the graph, we can see that x is positive, meaning x = 4, so a = 4.
Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.
a + b = 4 + 9 = 13. The answer is B.
y = 3x - 4 answer x = 11/3
4x + 3y = 1 answer -3/4y + 1/4
2-3x = y answer -1/3y + 2/3
Answer:
x-3
Step-by-step explanation:
You can factor out a 3 from both terms of 3x^2 - 9x to get
3(x^2 - 3x)
Answer:
The answer is the option B
Step-by-step explanation:
we know that
The sum of the internal angles of the polygon is equal to
where n is the number of sides
In this problem
so
substitute
Step 1
Find the value of y
-------> by supplementary angles
Solve for y
Step 2
Find the value of x
The sum of the internal angles of the polygon is equal to 
so
Solve for x
