Answer: -5
Step-by-step explanation:
For each question Sandra answered incorrectly her overall score was changed by -1 point.
Her overall score was -4 before she attempted her last question incorrectly. Since a wrong answer gives her -1 point and her overall is -4
We add her overall and her point from last question which sums up to -5.
So sandras final score is -5
39.37 in you would do 100 divided by 2.54
ANSWER
![- 5x - 3y = 0](https://tex.z-dn.net/?f=-%205x%20%20-%203y%20%3D%200)
EXPLANATION
The line that passes through the origin has equation of the form:
y=mx
Where m is the slope.
Since the line is parallel to the line through A(-3, 0) and B(-6, 5), they have the same slope.
The slope is given by:
![m = \frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%20)
![m = \frac{5 - 0}{ - 6 - - 3} = - \frac{5}{3}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B5%20-%200%7D%7B%20-%206%20-%20%20-%203%7D%20%20%3D%20%20-%20%20%5Cfrac%7B5%7D%7B3%7D%20)
Hence the required equation is:
![y = - \frac{5}{3} x](https://tex.z-dn.net/?f=y%20%3D%20%20%20-%20%5Cfrac%7B5%7D%7B3%7D%20x)
Multiply through by 3,
![3y = - 5x](https://tex.z-dn.net/?f=3y%20%3D%20%20-%205x)
In standard form, the equation is
![- 5x - 3y = 0](https://tex.z-dn.net/?f=%20-%205x%20%20-%203y%20%3D%200)
Answer:
y=2 x=5
Step-by-step explanation:
3x-2y=11
2x-3y=4
you multiply both equations to cancel one variable out. in this case you multiply the first equation by 2 and the second by -3
6x-4y=22
+ -6x-9y=12
--------------------------
0x+5y=10
y=2
you plug that in either equation
3x-2(2)=11
3x-4=11
3x=15
x=5
Answer:
A is the correct answer because this is true :D
