Answers
Answer:
SSimplifying
2x + -3y = 19
Solving
2x + -3y = 19
Solving for variable 'x'.tep-by-step explanation:
Simplifying
2x + -3y = 19
Solving
2x + -3y = 19
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
2x + -3y + 3y = 19 + 3y
Combine like terms: -3y + 3y = 0
2x + 0 = 19 + 3y
2x = 19 + 3y
Divide each side by '2'.
x = 9.5 + 1.5y
Simplifying
x = 9.5 + 1.5y

Answers
Answer:Liquid assets
Step-by-step explanation: Can be valued as cash
When paying for higher education, scholarships and grants can be considered liquid assets. Hence, option A is correct.
What is liquid assets?Liquid assets are assets that can be quickly converted into cash. Although while your assets are valuable possessions that may be traded for cash, not all of them can be sold immediately away for cash or without suffering a loss. A common liquid asset is cash.
Liquid assets include cash on hand, cash stored in a bank, and possessions that can be quickly and readily converted into cash. Common liquid assets include shares, bonds, certificates of deposit, and stocks.
No, an automobile is not considered to be a liquid asset. A car is regarded as a tangible asset that depreciates over time, is more difficult to sell, and is more subject to market swings. It is also challenging to make a quick turn.
Thus, option A is correct.

How many times larger than 2x10^3 is 6x10^6?
Answers
Answer: 5,998,000
Step-by-step explanation:
2x10^3= 2,000
6x10^6= 6,000,000
In translation, Use 1 x The Initial SIG FIGS, or first numbers. 10x10 is 100, and notice how 10 and 10 have 2 zeros, so 1x1 = 1 +00 is a way to construct the number.
In this case, the 10^x, the x can represent the number of zeros after our first value.
So, 6 + six zeros, or 6,000,000
and, 2 + 3 zeros, or 2,000
To find the difference, subtract the numbers from eachother and extract the absolute value, (meaning the final answer won't be negative).
So, 6,000,000 - 2,000 = 5,998,000, which is the answer to the prompt!

(2, 9) is the solution of the system of equations.
y = x + 7
y = 2x + 5
true or false
Answers
Answer:
True! Since if you replace x and y with 2 and 9, you will get 9 = 2 + 7 or 9 = 2 x 2 + 5 which makes the equation true.
Answer:
Yes it's TRUE that ( 2 , 9 ) is the solution of given equations .Step-by-step explanation:
In the question it is given that whether ( 2 , 9 ) is solution of system of equations that are y = x + 7 and y = 2x + 5 .
And we have to tell that it is true or false.
Solution : -
As in the question we're provided with ( 2 , 9 ) . So , Here :
Value of x is 2Value of y is 9( 1 )
[tex] \longmapsto \qquad \:y = x + 7[/tex]
Substituting value of x and y in equation :
[tex] \longmapsto \qquad \: 9 = 2 + 7[/tex]
[tex] \longmapsto \qquad \: \boxed{\bf{9 = 9}}[/tex]
As we see that left side is equal to right side .
Therefore ( 2 , 9 ) is the solution of y = x + 7 .( 2 )
[tex] \longmapsto \qquad \: y = 2x + 5[/tex]
Substituting value of x and y in equation :
[tex] \longmapsto \qquad \: 9 = 2(2) + 5[/tex]
[tex] \longmapsto \qquad \: 9 = 4 + 5[/tex]
[tex] \longmapsto \qquad \: \boxed{ \bf{9 = 9}}[/tex]
As we see that left side is equal to right side .
Therefore ( 2 , 9 ) is the solution of y = 2(x) + 5 .#Keep LearningA triangle has sides of lengths 12, 14, and 19. Is it a right triangle? Explain.

[tex](\frac{16}{3},- \frac{1}{9} )[/tex] or [tex]x=\frac{16}{3}, y=- \frac{1}{9}[/tex]
Step-by-step explanation:
Hello again!
We are given these two systems:
4x+1=5(x-3y)-6
3(x+6y)+4=9y+19
And we want to solve them for x and y.
First, let's do the distributive property to expand out what is in the parentheses.
4x+1=5(x-3y)-6 --> 4x+1=5x-15y-6
Now simplify 4x+1=5x-15y-6
Subtract 5x from both sides
4x+1=5x-15y-6
-5x -5x
__________
-x+1=-15y-6
Now add 15y to both sides
-x+1=-15y-6
+15y +15y
___________
-x+15y+1=-6
Subtract 1 from both sides
-x+15y=-7
Now for 3(x+6y)+4=9y+19:
3x + 18y + 4 = 9y + 19
Subtract 9y from both sides
3x + 9y + 4 = 19
Subtract 4 from both sides
3x + 9y = 15
Here is our system now:
-x+15y=-7
3x+9y=15
On 3x+9y=15, because all of the values are multiples of 3, we can actually divide it by 3.
3x+9y=15
÷3 ÷3
x + 3y = 5
So here it is again:
-x+15y=-7
x+3y=5
These equations can actually be solved using elimination! We will be adding these equations together to clear out a variable, solve for the uncleared variable, and then use the value of the uncleared variable to find the value of the cleared variable
So, add -x+15y=-7 and x+3y=5 together.
-x+15y=-7
+
x+3y=5
_____
18y=-2
Divide both sides by 18
y=[tex]-\frac{1}{9}[/tex]
Now substitute -1/9 as y into either -x+15y=7 or x+3y=5
Taking x+3y=5 for example,
x+3(-1/9)=5
multiply
x-1/3+5
Add 1/3 to both sides
x=5+1/3=16/3
So the answer is [tex]x=\frac{16}{3} , y=-\frac{1}{9}[/tex], or as a point, [tex](\frac{16}{3},- \frac{1}{9} )[/tex]
Hope this helps!
