<u>Algebra I</u>
- Terms/Coefficients
- Coordinates (x, y)
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 2x - 7
y = -x + 5
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 2x - 7 = -x + 5
- [Addition Property of Equality] Isolate <em>x</em> terms: 3x - 7 = 5
- [Addition Property of Equality] Isolate <em>x</em> term: 3x = 12
- [Division Property of Equality] Isolate <em>x</em>: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = -x + 5
- Substitute in <em>x</em>: y = -4 + 5
- Add: y = 1
Answer: AOB
This is because angle AOB on top adds with BOC down below to get the largest angle AOC. See the diagram below.
Answer:
x<-3
The graph in the attached figure
Step-by-step explanation:
<u><em>The correct question is</em></u>
Solve the inequality. Graph the solution.
x+5<2
we have
Solve for x
Subtract 5 both sides
The solution is the interval (-∞,-3)
All real numbers less than -3
In a number line, the solution is the shaded area at left of x=-3 (open circle)
The number x=-3 is not included in the solution
The graph in the attached figure
I think the answer would be 1,000
10x10= 100 (power of 2)
10x10x10= 1,000 (power of 3)
Hopefully this helps :) You can ask any questions if you don’t understand
