Multiply first cause it’s in the parentheses. To multiply fractions you go straight across
1/2 x 3/8
1 x 3 = 3
2 x 8 = 16
So you get
3/16
When dividing fractions you have to flip the second fraction and multiply the same.
So 3/4 divided by 3/16
Flip 3/16 to 16/3
So now
3/4 x 16/3
16 x 3 = 48
4 x 3 = 12
48/12
Simplified is 4

Does x=5 satisfy the equation 3x + 2 +5x= 95 explain
Answer:
No
Step-by-step explanation:
3x + 2 +5x
if x=5
3(5)+2+5(5)
=15+2+25
=42 which is not equal to 95
No, it doesn't satisfy the equation
Step-by-step explanation:
3x + 2 +5x = 95
Now putting the value of x
3×5 + 2 + 5×5 = 95
15 + 2 + 25 = 95
42 ≠ 95
Hence, x = 5 doesn't satisfy the equation 3x + 2 +5x= 95

What two consecutive intergers dose the value below lie?
-√156
Answer: First we need to create an equation
x+x+2+x+4=156
3x+6=156
3x=156–6
3x=150
x=50
The answer is 50,52, and 54.
Check
50+(50+2)+(50+4)=156
50+52+54=156

At a store, a televisionset has a marked price of $25,000. However there is a vat of 17.5% paid on all purchases. How many will the customer pay in total for the tv set
Answer:
$29,375
Step-by-step explanation:
Find 17.5% of 25,000 and add it to 25,000 to get the total.
25,000x17.5% = 4,375
25,000 + 4,375 =
29,375.
How to determine values of a,b and c
(i) The graph of f is symmetric about the y-axis - this is another way of saying f is an even function, which means
[tex]f(x) = f(-x) \iff \dfrac{ax+b}{x^2-c} = \dfrac{-ax+b}{x^2-c}[/tex]
The denominator remains unchanged, so
ax + b = -ax + b
Solve for a :
ax = -ax
2ax = 0
a = 0
(The alternative is that x = 0, but if that were the case then there would be infinitely many choices for a.)
So
[tex]f(x) = \dfrac{b}{x^2-c}[/tex]
(ii) Since
[tex]\displaystyle \lim_{x\to2^+}f(x) = +\infty[/tex]
it follows that x - 2 must be a factor of the denominator. If that's true, then
x ² - c = (x - 2) (x - r )
for some other root r of x ² - c. Expanding the right side gives
x ² - c = x ² - (2 + r )x + 2r
so that
-(2 + r ) = 0 ===> r = -2
2r = -c ===> -c = -4 ===> c = 4
and so
[tex]f(x) = \dfrac{b}{x^2-4}[/tex]
(iii) Finally, we're given that f ' (1) = -2. Differentiating f gives
[tex]f'(x) = -\dfrac{2bx}{(x^2-4)^2}[/tex]
so that
[tex]f'(1) = -\dfrac{2b}{(1^2-4)^2} = -\dfrac{2b}{9}[/tex]
Then
-2b/9 = -2 ===> b = 9
and we find that
[tex]f(x) = \dfrac{9}{x^2-4}[/tex]
