Answer:
{x = -19
, y = 25
Step-by-step explanation: System solved by elimination
Solve the following system:
{6 x + 5 y = 11 | (equation 1)
{x + y = 6 | (equation 2)
Subtract 1/6 × (equation 1) from equation 2:
{6 x + 5 y = 11 | (equation 1)
{0 x+y/6 = 25/6 | (equation 2)
Multiply equation 2 by 6:
{6 x + 5 y = 11 | (equation 1)
{0 x+y = 25 | (equation 2)
Subtract 5 × (equation 2) from equation 1:
{6 x+0 y = -114 | (equation 1)
{0 x+y = 25 | (equation 2)
Divide equation 1 by 6:
{x+0 y = -19 | (equation 1)
{0 x+y = 25 | (equation 2)
Collect results:
Answer: {x = -19
, y = 25
Hi there! Your answer is -1/9
Please see an explanation for a better and clear understanding to your problem.
Any questions about my answer and explanation can be asked through comments!:)
Step-by-step explanation:
The formula above is slope formula. We will be using this to find a slope of a line.
From the graph, there are two points which are (4,0) and (-5,1).
You can either let (4,0) = (x1, y1) or (x2, y2) but I will be letting (-5,1) =(x2, y2)
Substitute the coordinate points in.
Hence, the slope is - 1/9. If you are curious where m-term comes from, it comes from y = mx+b where m = slope and b = y-intercept.
If Benny is 12 right now, that means that he is twice his sisters age because he is 200% of or 2 times his sister's age. His sister right now is 6 years old then.
After 4 years, Benny will be 16 (add 4 to 12) and his sister will be 10.
To find the percentage,divide his age by his sister's age and make it a percentage.
16/10=1.6=160%
Hope this helps.
One way is that an inequality can have a dotted or solid line and another way is that you shade one side of the on an inequality.
