Convert 3 1/2 to a improper fraction:
3 1/2 = 7/2
Divide 7/2 by 1/4:
7/2 ÷ 1/4
7/2 × 4/1
28 / 2
= 14

Answer:
Move all terms to the left side of the equation and simplify.
3x²−12x−21=0
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=3, b=−12, and c=−21 into the quadratic formula and solve for x.
(12±√(−12)²−4⋅(3⋅−21)0/2⋅3 Simplify => x=2±√11
The result can be shown in multiple forms.
Exact Form: x=2±√11
Decimal Form: x=5.31662479…,−1.31662479…

Answer:
Michael needs to purchase 1 5/8 feet more of metal flashing.
Step-by-step explanation:
To have the same denominator in both fractions, you can multiply 4 by 2. This will turn out to be 8, resulting in 8 being our common denominator. To achieve this, multiply:
<u>7</u> x <u>2</u> = <u>14</u> or 1 6/8
4 2 8
We next add both fractions together, resulting in:
3 1/8 + 1 6/8 = 4 7/8
The fraction 6 1/2 can also be expressed as 6 4/8, so to find out how much metal Michael still needs to purchase, subtract 4 7/8 from 6 4/8.
The change in average height of the trees on the farm with respect to the number of years since the trees were planted is = 7ft/yr.
<h3>What is the linear relationship?</h3>
- A statistical word used to express a straight-line relationship between two variables is a linear relationship (or linear association).
- Graphs and mathematical equations of the form y = mx + b can both be used to represent linear relationships.
- In everyday life, linear relationships are quite prevalent.
The midpoint of the axis is=
In the intercept form-
- y= mx+b
- y= mx+3
- y= mx +3
- 10 =m(1) + 3
subtracting 3 from both sides-
Hence, the rate of change is 7ft/yrs.
