Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 7x + 10
y = -4x - 23
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 7x + 10 = -4x - 23
- [Addition Property of Equality] Add 4x on both sides: 11x + 10 = -23
- [Subtraction Property of Equality] Subtract 10 on both sides: 11x = -33
- [Division Property of Equality] Divide 11 on both sides: x = -3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = 7x + 10
- Substitute in <em>x</em>: y = 7(-3) + 10
- Multiply: y = -21 + 10
- Add: y = -11
The area of the rectangle is 12 square foot because in or to determine the area you need to multiply the length times height.
Answer:
8 m/s^2
Step-by-step explanation:
You can use the equation a = v^2 / r
That is acceleration is equal to velocity squared divided by the radius which in this problem is the length of the string. The velocity is 4m/s and the r the radius is 2 m. Now you can square 4 m/s to get 16 m^2/s^2 THEN you divide by 2 m and the m^2 turns to just m and the 16 to an 8. So, that leaves you with acceleration or in this case centripetal acceleration equals 8 m/s^2.
a = 8 m/s^2 or 8 meters per second squared.
