- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
4x + y = 2
y = x - 3
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: 4x + (x - 3) = 2
- Combine like terms: 5x - 3 = 2
- Isolate <em>x</em> term: 5x = 5
- Isolate <em>x</em>: x = 1
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: y = x - 3
- Substitute in <em>x</em>: y = 1 - 3
- Subtract: y = -2
Answer:
to what??????
Step-by-step explanation: ???????
I would make a table and plug in values for "x" in the equation to find f(x) or y
x = 0
(there is a rule that when the exponent is 0, the result is 1)
f(0) = 2 (0,2)
x = 1
f(1) = 6 (1,6)
You could do more points.
But these two points shows that the y-intercept (the y value when x = 0 or (0,y)) is 2, and that the graph is increasing.
Your answer is B
Answer:
a=18
Step-by-step explanation:
-2a-10+a=-28
-1a-10=-28
+10 +10
-1a=-18
divide by -1
a=18
