Answer: first can u answer mine Sara is playing a board game. The probability that Sara will score a point on her next turn is 1/3. Which statement describes the probability that Sara will score a point on her next turn? is it likely or unlikely
Step-by-step explanation:
Logb1=0 log b 1 = 0 . This follows from the fact that b0=1 b 0 = 1 .
logbb=1 log b b = 1 . This follows from the fact that b1=b b 1 = b .
logbbx=x log b b x = x . This can be generalized out to logbbf(x)=f(x) log b b f ( x ) = f ( x ) .
Answer:
(-2, -8)
x = -2
y = -8
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define systems</u>
13x - 6y = 22
x = y + 6
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Substitution</em>
- Substitute in <em>x</em>: 13(y + 6) - 6y = 22
- Distribute 13: 13y + 78 - 6y = 22
- Combine like terms: 7y + 78 = 22
- Isolate <em>y</em> term: 7y = -56
- Isolate <em>y</em>: y = -8
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define original equation: x = y + 6
- Substitute in <em>y</em>: x = -8 + 6
- Add: x = -2
Answer:
Step-by-step explanation:
In exponential form, those look like this:
10⁵ × 10⁴
Those 10's are not just regular numbers, they're called bases. The rule for multiplying bases with exponents is that if you're multiplying like bases, you add the exponents. We do indeed have like bases, so we add the exponents 5 and 4 together (which is 9) so the solution to this simplification is 10⁹. If the bases are not like, this rule does not apply. In fact, no rule applies!!
