3 can be squared twice to get the value of 9. 3x3=9
Answer:
v=8
Step-by-step explanation:
Let's solve your equation step-by-step.
16v−9v=56
Step 1: Simplify both sides of the equation.
16v−9v=56
16v+−9v=56
(16v+−9v)=56(Combine Like Terms)
7v=56
7v=56
Step 2: Divide both sides by 7.
7v
7
=
56
7
v=8

Answer:
y = -5/7x - 55/7
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Step 1: Define
Slope <em>m</em> = -5/7
Random point (-4, -5)
y = -5/7x + b
Step 2: Find y-intercept <em>b</em>
-5 = -5/7(-4) + b
-5 = 20/7 + b
b = -55/7
Step 3: Write linear equation
y = -5/7x - 55/7

Answer:</h3>
-y³ -6y²x +30
<h3>
Step-by-step explanation:</h3>
When parentheses are eliminated and the y variable placed first in each term, the expression simplifies to ...
... 15 -7y²x -y³ +y²x +15
Arranging like terms together, we have ...
... -y³ +y²x(-7 +1) +(15 +15)
... -y³ -6y²x +30
_____
The two different 3rd-degree terms can be expressed in either order. I have chosen to list the term with the largest exponent first. The expression could also be written with the same-degree terms in "lexicographical order", meaning the expression would be written ...
... -6xy² -y³ +30
Answer:
y = - 5x - 1
Step-by-step explanation:
The first thing to do (always) is pay attention to x =0. That at least gives you a partial answer. y = y' - 1. when you put 0 in for whatever y' is you get 0. What about the other numbers? How did they come about.
We have another clue. Whenever you put in a positive number for x, you get a negative answer for y. That's interesting. So y' has a minus sign associated with it.
y = -ax - 1 Make a>0 so there is only 1 minus sign. x cannot have an even power, because an even power would make everything positive except the -1.
So we'll start with y= - ax - 1 We'll also make the assumption that a = 1
y = - x - 1 That won't work. a >1 otherwise x = 2 won't give - 11
y = -ax - 1
let x = 2
let y = - 11 Solve for a
y = - ax - 1
- 11 = -a*-2 - 1 add 1 to both sides
-11 + 1 = - a(-2) - 1 + 1
- 10 = -2a Divide by - 2
- 10/-2 = -2a/-2
a = 5
Answer: y = - 5x - 1
