Show that a/(b+1) - a/(b+1)^2 can be written as ab/(b+1)^2
Step-by-step explanation:
[tex] \dfrac{a}{b+1} - \dfrac{a}{(b+1)^2} = [/tex]
[tex] = \dfrac{b + 1}{b + 1} \times \dfrac{a}{b+1} - \dfrac{a}{(b+1)^2} [/tex]
[tex] = \dfrac{a(b + 1)}{(b+1)^2} - \dfrac{a}{(b+1)^2} [/tex]
[tex] = \dfrac{ab + a}{(b+1)^2} - \dfrac{a}{(b+1)^2} [/tex]
[tex] = \dfrac{ab + a - a}{(b+1)^2} [/tex]
[tex] = \dfrac{ab}{(b+1)^2} [/tex]
Answer:
Proof
Step-by-step explanation:
[tex] \frac{a}{(b + 1)} - \frac{a}{ {(b + 1)}^{2} } [/tex]
Multiply the first fraction (the numerator and the denominator) by
[tex](b + 1) \\[/tex]
In order to get common denominators for both fractions
[tex] \frac{a(b + 1)}{ {(b + 1)}^{2} } - \frac{a}{ {(b + 1)}^{2} } [/tex]
Then expand the first fraction's numerator and subtract fractions to get your answer
[tex] \frac{ab + a}{ {(b + 1)}^{2} } - \frac{a}{ {(b + 1)}^{2} } = \frac{ab}{ {(b + 1)}^{2} } [/tex]

What is the equation of the line?
oy-- 1 2x + 7/10
O y=-3x+ 1
Oy - - 1 3 x 1
o y = -1 3 x - 4
Answer:
The answer is y=-1/4x+11/16
Step-by-step explanation:
y-y=m(x-x1)
y-1=-1/4(x-(-5/4))
y-1=-1/4x-5/16
+1 +1
y=-1/4x+11/16

Two - step equations:
1) x/2 + 9 = 8
2) 10= -4 + 2/3x
Equations with variables on both sides:
1) 3x + 7 = 2x
2) 3 + 9x + 8 = 6x - 4
3) 3(x + 7) = 15x
4) 2 + 9(x - 2) = 6x + 2

Let me know if you need explanation.
Answer:
y = 4/3x+4
Step-by-step explanation:
First, we must find the slope. (m=y2-y1/x2-x1)
Once you subsitute the numbers, you'll get 12/9. Reduce that to 4/3
After that, replace y = mx +b with the any of the ordered pairs. I chose 3 and 8.
So. 8=4/3(3)+b (b is the y intercept) 3/4 is our slope, 8 is the y, and 3 is the x.
So, multiply 3/4 by 3. You'll get 4.
Then, subtract 4 on both sides (8-4) which gets you 4.
Therefore, b (y intercept) = 4.
y = mx+b
y=4/3x+4.

Answer:
29.) y = -1.5x - 20
30.) y = 6 - 3x
Step-by-step explanation:
29.) For parallel lines; M1 = M2
put the equation in the form y = mx + c
the equation becomes 2y = 14 - 3x
therefore y = 7 - 1.5x.
For the points, introduce another point; (x,y) and the initial (-6,-11)
(y - - 11) ÷ ( x - - 6) = -1.5
y+11 = -1.5x - 9
y= -1.5x - 20
30.) still following the same procedure, only that M1 × M2 = -1
M1 = 1/3, M2 = -3
(y + 9)/(x - 5) = -3
y + 9 = 15 - 3x
y = 6 - 3x

Deena deposited $48 in a new bank account. After buying groceries, she had $19 left in the account. Then she paid her cell phone bill, which was $31. Select all the true statements about Deena’s account.
To start, Deena had a positive balance.
In this situation, 0 represents an empty bank account.
After paying for groceries, Deena had a negative balance.
After paying her cell phone bill, Deena had –$12 in the account.
The smallest balance in the account was $19.
Step-by-step explanation:
Step one:
given data
amount deposited=$48
after the purchase of groceries
account balance= $19
cell phone bill, which= $31
Step two:
The account balance after paying for groceries will be
=19-31= $-12
she will have a deficit of $12, hence a negative account balance
To start, Deena had a positive balance. -------True
In this situation, 0 represents an empty bank account. -----True
After paying for groceries, Deena had a negative balance. ---True
After paying her cell phone bill, Deena had –$12 in the account. ...True
