Answer: Current will reduce by half
Step-by-step explanation:
The formula for Current is;
Current = Voltage/ Resistance
Say for instance that Voltage is 5 volts and Resistance is 2 ohms. Current will be;
= 5/2
= 2.5 amps
If Voltage is decreased by one half to 2.5 while resistance is held constant, current becomes;
= 2.5/2
= 1.25 amps
Current went from 2.5 to 1.25 amps.
This shows that current will reduce by half if the voltage is decreased by one half while the resistance is held constant.

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]

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

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.
I need this ASAP, I will give as many points as possible on a question like this and give brainliest! I need a bit of work for it just to show my work!
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

In triangle XYZ, m∠Z > m∠X + m∠Y. Which must be true about △XYZ?
m∠X + m∠Z 90°
∠X and∠Y are complementary
m∠X + m∠Y < 90°
Answer:
m < X + m < Y < 90
Step-by-step explanation:
For the triangle XYZ, m∠Z > m∠X + m∠Y we see that because the total internal angles of a triangle is 180,m∠X + m∠Y < 90° is a true assertion
Option C is correct
What must be true about triangle XYZ?Generally, A triangle's major feature is its total internal angles as 180
Therefore
if m∠Z > m∠X + m∠Y this means that m<z must be greater than 90 degrees
This goes to show us that
m<X + m<Y < 90 because as we earlier mentioned the total internal angles of a triangle is 180 .
In conclusion, For the triangle XYZ
m∠X + m∠Y < 90° is a true assertion

Write an equation passing through the point and parallel to the given line
(4,7); y = 3x + 6
Thank you!
Answer:
Step-by-step explanation:
y=3x+6
slope is 3, so y=3x+[unknown].
We insert the point (4,7) into the equation.
7=3*4+[unknown]
7=12+[-5]
so the answer is
y=3x-5
Answer:
y = 3x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 6 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes, thus
y = 3x + c ← is the partial equation
To find c substitute (4, 7) into the partial equation
7 = 12 + c ⇒ c = 7 - 12 = - 5
y = 3x - 5 ← equation of parallel line
you need to write equally fraction but the catch is the denominators have to be the same for 1/4
