Answer:
3.) 63=3x+7y
4.) Y-intercept is 9
Step-by-step explanation:
(For 3) For every time a person gets a touchdown, x represents that
for every time a person person scored a successful extra-point attempt, y represents that.
And they team scores 63, so....
the equation would look like this
63=3x+7y
(For 4) You find the y-intercept by turning the standard form equatio into the slop intercept form
(Helper's note, multiplying by its reciprocal is the same as dividing it by a whole number, in the case dividing the number by 7 is the save as multiplying the number by )
Then plugging x=0 and solve for y, which in this case, y=9
(For the graphing) Turn 63=3x+7y into a slope intercept form, which is and graph from there
Answer:
Step-by-step explanation:
We are trying to evaluate this integral.
The first thing that we have to do is understand this region in the plane.
If you graph it looks something like the photo I join.
Now we need to describe that same region in polar coordinates.
That same region in polar coordinates would be
Now remember that when we do the polar transformation we use the following formula
Then our integral would be
Answer: 18/5
Step-by-step explanation: hope this helps pls mark me brainliest
there are nine ducks and 3 swans
sqrt of 9 equals 3
3 + 9 = 12
It would now cost $11. 45% of 20 is 9, therefore, you would subtract 9 from 20 (since it is getting marked down).
