Answer:
x^4 + 5x^3 - 12x^2 + 5x + 1
Question:
The relationship between t and r is expressed by the equation 2t+3r+6 = 0. If r increases by 4, which of the following statements about t must be true?
Answer:
The value of t is reduced by 6 when the value of r is increased by 4
Step-by-step explanation:
Given
Required
What happens when r is increased by 4
<em>-------- Equation 1</em>
Subtract 2t from both sides
--- <em>Equation 2</em>
When r is increased by 4, equation 1 becomes
Note that the increment of r also affects the value of t; hence, the new value of t is represented by T
Open bracket
Rearrange
<em>Substitutr -2t for 3r + 6 [From equation 2]</em>
Make T the subject of formula
Divide both sides by 2
This means that the value of t is reduced by 6 when the value of r is increased by 4
Answer:
44
Step-by-step explanation:
The absolute value of a number tells us how far the number is from 0 on a number line. Because 44 is 44 places away from 0, the absolute value of 44 is 44.
The absolute value of -44 would also be 44 because it's also 44 places away from 0.
I hope this helps!
X/5 + 12 =25
First, the quotient of x and 4 is simply put into a division as x/4.
Then, 12 more is on the right side of x/4 because my teacher taught me that when it says 12 more, it’s on the right side.
Is equal to means = 25
Answer:
r - 5 = 2c
r = 75
Step-by-step explanation:
To write an equation for the problem, we first need do declare the value of the number of apps cora has.
Let c = Cora's apps
r - 5 = 2c
r - 5 is used to indicate that Rita deleted 5 apps.
2c is used to represent the twice the number of apps Cora has.
Now you said that Cora had 35 apps.
Let's plug that into the equation.
r - 5 = 2c
r - 5 = 2(35)
r - 5 = 70
Now we transpose the -5 to the other side to leave r.
r = 70 + 5
r = 75
So if Cora has 35 apps, then Rita will have 75 apps.
