The given expression becomes undefined when y=5 or y = -3. The answer is option D.
Step-by-step explanation:
The value of the given expression becomes undefined when the denominator equals 0.
Hence to find the value of y which makes the expression undefined, we can equate the value of the denominator to zero and solve it .
Step 1
Equate the denominator to 0.
y^{2} - 2y -15 = 0
Step 2
Solve the above equation to get the value of y.
y^{2} - 2y -15 = 0
=> (y-5)(y+3) =0 [ Roots of the quadratic equation]
=> y = 5 or y = -3.
Hence when y = 5 or y = -3 the denominator becomes 0, which makes the expression (2y+7)/0 and hence it is undefined.
Answer:
<u>Question 19</u>: 4(x+5)+3 = 4·x+4·5+3 (second option).
<u>Question 20</u>: (117.50-83.50)+6(22.50+3) = 34+6(25.50) --> (last option).
<u>Third question</u>:
375=x-28
x= 375+28
x= 403
<u>Fourth question</u>:
0.57, 0.66, 0.75, 0.84,...
0.66-0.57= 0.09 and 0.75-0.66= 0.09 and 0.84-0.75= 0.09
So, the next three terms are: 0.93, 1.02, 1.11
Answer:
an =7+4(n-1)
Step-by-step explanation:
an =a1+ d(n-1) is the equation for an arithmetic sequence
When n=4 an =19
19 =a1 + d(4-1)
19 =a1 + d(3)
When n =6 an =27
27 = a1 +d*(6-1)
27 = a1 +d*5
Now we have 2 equations and 2 unknowns
19 =a1 + d(3)
27 = a1 +d*5
Subtract them to eliminate a1
27 = a1 +d*5
-19 =a1 + d(3)
-----------------------
8 = 2d
Divide by 2
8/2 = 2d/2
4 =d
The common difference is 4
Now we need to find a1
27 = a1 +d*5
27 = a1 + (4) *5
27 = a1+ 20
Subtract 20 from each side
27-20 =a1 +20-20
7 =a1
The initial term is 7
an = a1+ d(n-1)
an =7+4(n-1)
