Answers
Answer:
The correct answers are:
- The system has one solution.
- The lines intersect.
Step-by-step explanation:
We are given system of linear equations as:
y=x-4--------(1)
and 3 y-x= -7----------(2)
on substituting the value of 'y' from equation (1) into equation (2) we have:
3(x-4)-x=-7
⇒ 3x-3×4-x=-7
⇒ 3x-x= -7+12
⇒ 2x=5
⇒
also putting the value of x into equation (1) we have:
- Hence, we get a unique value of x and y on solving the system of linear equations.
Hence, the system has one solution.
- the slope for line y=x-4 is 1 ( since on comparing the equation with y=mx+c; where m denotes the slope of line and c is the y-intercept)
y-intercept is -4
but the slope of line 3y-x = -7 i.e.
hence the slope of second line is: .
and y-intercept is .
- They represent different lines.
- the lines intersect at the point

80%
Ummm bro the explanation is simple he keeps 8/10 and he saves 2/10 sooo
8/10 x 10 = 80/100 spends 80%
2/10 x 10 = 20/100 saves 20%
Easy peasy...
Final answer:
Glen saves $2 out of every $10 he earns, which is 20%. Therefore, he spends 80% of his earnings. That's the percentage of the money he gets to spend.
Explanation:
To figure out what percent of his earnings Glen gets to spend, you need to look at the portion that he is not required to save. If he earns $10 and is required to save $2, he gets to spend $7 out of every $10.
This means Glen gets to keep 80% of his earnings. The reasoning here is simple: for every $10, he saves $2 (which is 20% of $10) and the rest, which is $8, he gets to spend. Therefore, the percentage of his money that he gets to spend is $8/$10*100 which equals to 80%.

0=-16t^2+24
factor out -8
0=-8(2t^2-3)
we know that
0=2t^2-3 since factors have to multiply to 0
add 3 to both sides
3=2t^2
divide both sides by 2
1.5=t^2
sqrt both sides

Final answer:
To solve the given pair of linear equations y = -x + 5 and y = 2x - 7, you can use the elimination method. Multiply the second equation by -1, add the equations together to eliminate y, solve for x, and substitute the value of x back into either equation to find y. The solution is x = 4 and y = 1.
Explanation:
To solve the given pair of linear equations:
y = -x + 5
y = 2x - 7
You can use the method of substitution or elimination. Let's use the elimination method:
Step 1: Multiply the second equation by -1 to make the coefficient of y in both equations the same:
y = -x + 5
-y = -2x + 7
Step 2: Add the equations together to eliminate y:
0 = -3x + 12
Step 3: Solve for x:
3x = 12
x = 4
Step 4: Substitute the value of x back into either equation to find y:
y = -4 + 5
y = 1
So, the solution to the given pair of linear equations is x = 4 and y = 1.

The complete question is given below:
Solve the given pair of linear equation in two variable.
y = -x + 5
y = 2x - 7
Answer: x=4, y=1
Step-by-step explanation:
Because y=y, you can make an equation that is -x+5=2x-7. Then add the x to the right side, so it would be 5=3x-7. Then add the 7 to the left side to get all of the numbers in one place. So it would be 12=3x. Divide by 3 on both sides and you get x=4. Then plug x into either one of the original equations. Both equations should get you the same answer for y. Y=-4+5. Y=1. And the other equation. Y=2x-7, y=8-7. Y=1
