- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-2x - y = 0
10x + y = -8
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: 8x = -8
- Isolate <em>x</em>: x = -1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -2x - y = 0
- Substitute in <em>x</em>: -2(-1) - y = 0
- Multiply: 2 - y = 0
- Isolate <em>y</em> term: -y = -2
- Isolate <em>y</em>: y = 2
Distance divided by time is speed. To find the rate of speed, divide 40 yards by 4.24 seconds which is approximately 9.43 yards per second. 9.43 yards per second is the rate of speed.
