The answer is B: 1/6 because the probability will be 3/18. Simplified, it's 1/6. Hope this helped!
Let d = number of stamps from John (4 letters, d is 4th letter, etc)
<span>Let e = number of stamps from Johan </span>
<span>Let h = number of stamps from Jonathan </span>
<span>Johan and Jonathan have the same number of stamps, so: </span>
<span>e = h </span>
<span>2 times Johan's collection is 11 less than 5 times John's collection, so: </span>
<span>2e = 5d - 11 </span>
<span>3 times Jonathan's collection is 3 less than 7 times John's collection,so: </span>
<span>3h = 7d - 3 </span>
<span>Now we have three equations and three unknowns. You're asked for the number of stamps in John's collection, so you want the value to variable "d". </span>
<span>Since e = h, we can substitute "h" for "e" in the second equation. </span>
<span>2h = 5d - 11 </span>
<span>3h = 7d - 3 </span>
<span>now we have two equations and two unknowns. I'll use elimination, starting with multiplying the first equation by -3 and the second one by 2. </span>
<span>-6h = -15d + 33 </span>
<span>6h = 14d - 6 </span>
<span>now add both together and you have an equation with one unknown remaining: </span>
<span>0 = -d + 27 </span>
<span>d = 27 </span>
<span>So your answer is 27 stamps. If you want to know how many stamps the others have, you can work back and solve for e and h.</span>
Answer: See explanation
Step-by-step explanation:
You didn't give the expressions but here are some expressions
a. ✓4x²y^4. 1. 2x✓y
b. ✓8x²y. 2. 2y✓2x
c. ✓4x²y. 3. 2xy²
d. ✓16xy². 4. 2x✓2y
e. ✓8xy². 5. 4y✓x
a. ✓4x²y^4 = ✓4 × ✓x² × ✓y^4
= 2 × x × y²
= 2xy²
Therefore, ✓4x²y^4 = 2xy²
b. ✓8x²y = ✓8 × ✓x² × ✓y
= ✓4 × ✓2 × ✓x² × ✓y
= 2 × ✓2 × x × ✓y
= 2x✓2y
Therefore, ✓8x²y = 2x✓2y
c. ✓4x²y = ✓4 × ✓x² × ✓y
= 2 × x × ✓y
= 2x✓y
Therefore, ✓4x²y = 2x✓y
d. ✓16xy² = ✓16 × ✓x × ✓y²
= 4 × ✓x × y
= 4y✓x
Therefore, ✓16xy² = 4y✓x
e. ✓8xy² = ✓8 × ✓x × ✓y²
= ✓4 × ✓2 × ✓x × ✓y²
The independent variable influences the dependent variable
basically, make the equation equal to y
easy
y-6x-9=0
add 6x+9 to both sides
y=6x+9
f(x)=6x+9
