<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-x + 4y = -8
-5x - 4y = -16
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine equations: -6x = -24
- Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -x + 4y = -8
- Substitute in <em>x</em>: -4 + 4y = -8
- Isolate <em>y</em> term: 4y = -4
- Isolate <em>y</em>: y = -1
Answer: The first one. a^2 +b^2 = c^2
Step-by-step explanation:
Answer:
y=mx+b
Step-by-step explanation:
The slope-intercepts formula, the y = y coordinate, m = slope, x = x coordinate, b = y intercept
D= sqrt( (6-4)^2 + (5sqrt2 - 3sqrt2)^2 )
It's d= 3,46 i think
Answer:
y=1x-4
Step-by-step explanation:
you should start using desmos trust me it will HELP U OUT
btw the slope of a perpendicular line is the opposit of the first line
