1 whole can be written as 12/12 and 12/12- 7/12= 5/12
Answer:
0.98
Step-by-step explanation:
Explanation
The investment of $10,000 decreases by 2% every year. So the following year is usually (100 - 2)=98% of the previous year. This is a geometric progression.
In this case the first term = 10000
The second term = 98% × 10000 = 9800.
The common ratio = 9800/10000=49/50
The multiplicative rate of change that should be in Hal’s function = 49/50=0.98.
The equation of the exponential rate would be;
10,000ₓ0.98ⁿ.
where n is the number years.
Answer:
Area: 12x + 66
Perimeter: 2x + 35
Step-by-step explanation:
Area is the base and the height multiplied, 12(x) + 12(5.5), which is simplified to 12x + 66.
Perimeter is all the sides added together, (x + 5.5) + (x + 5.5) + 12 + 12, which is grouped to be 2x + 11 + 24, then simplified to 2x + 35.

Answer:
top down: ∞, 0, 1, 0, ∞
Step-by-step explanation:
The equation will have infinite solutions when the left side and right side simplify to the same expression. This is the case for the first and last expressions listed.
2(x -5) = 2(x -5) . . . . expressions are already identical
x +2(x -5) = 3(x -2) -4 ⇒ 3x -10 = 3x -10 . . . the same simplified expression
__
The equation will have no solutions when the x-coefficients are the same, but there are different added constants.
5(x +4) = 5(x -6) ⇒ x +4 = x -6 . . . not true for any x
4(x -2) = 4(x +2) ⇒ x -2 = x +2 . . . not true for any x
__
The equation will have one solution when coefficients of x are different.
5(x +4) = 3(x -6) ⇒ 2x = -38 ⇒ x = -19
Answer:
The slope is 2
Points are (0,-3), (3/2,0)(5,7)(-1,-5)
