3) if the cost of 1 pen is Rs.10, find the cost of 5 pen
Answer: 5 pens cost Rs.50
Explanation: Since 1 pen costs Rs.10, you will need to multiply the number of pens (1) and the cost of that number of pens (Rs.10) by the amount of pens you must find the cost for (5). Since 10 times 5 is 50, that means that 50 is the cost of 5 pens.
I hope this helps!

Find two linear functions p(x) and q(x) such that (p (f(q(x)))) (x) = x^2 for any x is a member of R?
Let p(x)=kpx+dp and q(x)=kqx+dq than
f(q(x))=−2(kqx+dq)2+3(kqx+dq)−7=−2(kqx)2−4kqx−2d2q+3kqx+3dq−7=−2(kqx)2−kqx−2d2q+3dq−7
p(f(q(x))=−2kp(kqx)2−kpkqx−2kpd2p+3kpdq−7
(p(f(q(x)))(x)=−2kpk2qx3−kpkqx2−x(2kpd2p−3kpdq+7)
So you want:
−2kpk2q=0
and
kpkq=−1
and
2kpd2p−3kpdq+7=0
Now I amfraid this doesn’t work as −2kpk2q=0 that either kp or kq is zero but than their product can’t be anything but 0 not −1 .
Answer: there are no such linear functions.

Determine if the sequence 0.2 comma 1 comma 5 comma 25 comma... is arithmetic or geometric. Then identify the next term in the sequence.
A
geometric; 125
B
arithmetic; 75
C
arithmetic; 125
D
geometric; 75
Answer:
The answer would be C.

4200. If the sale price is 5/6 of
the original Price . How much did
trey pay for the computer?
Answer:
3500
Step-by-step explanation:
To find a fraction of something just keep in mind that "of" means to multiply (when dealing with fractions and percents). In this case we want to know what 5/6 of 4200 is. So do (5/6)*4200 and that equal 3500.

→ [tex]-4 \frac{4}{35}[/tex]
Step-by-step explanation:
[tex]3\frac{2}{7} - 7\frac{6}{15}[/tex]
[tex]=\frac{23}{7} - 7\frac{6}{15}[/tex]
[tex]=\frac{23}{7} - 7\frac{2}{5}[/tex]
[tex]=\frac{23}{7} - 7\frac{37}{5}[/tex]
[tex]=\frac{-144}{35}[/tex]
[tex]=-4 \frac{4}{35}[/tex]
Therefore, [tex]-4 \frac{4}{35}[/tex] is your answer.

Which best describes the graph of the function f(x) = 4(1.5)x?
Answer:
B

Answer:
-5x-2=11
+2
-5x=9
÷-5
x=1.8
Step-by-step explanation:
Answer:
x = -2.6
or x=-2 and 3/5
Step-by-step explanation:
Simplifying
11 = -5x + -2
Reorder the terms:
11 = -2 + -5x
Solving
11 = -2 + -5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5x' to each side of the equation.
11 + 5x = -2 + -5x + 5x
Combine like terms: -5x + 5x = 0
11 + 5x = -2 + 0
11 + 5x = -2
Add '-11' to each side of the equation.
11 + -11 + 5x = -2 + -11
Combine like terms: 11 + -11 = 0
0 + 5x = -2 + -11
5x = -2 + -11
Combine like terms: -2 + -11 = -13
5x = -13
Divide each side by '5'.
x = -2.6
Simplifying
x = -2.6
