Answer:
2
Step-by-step explanation:
If he uses 1 hour to practice harmonica, one our on homework, and another hour doing chores. He will be spending twice as much time practicing harmonica and doing homework than he would spend on chores.
Since x is the length, then x+7 has to be the width.
The area of a rectangle can be found via the formula :
A = length * width
So if we replace the area with the given number (170) and the length, and width, with what we assumed, we get..
170 = x * (x+7)
[which is.. ]
170 = x^2 +7x
0 = x^2 +7x - 170
And that is the answer.
Answer:
The answer would be 5/5 or 1
Step-by-step explanation:
since they have the same denominator the its pretty simple add the numerators(the top numbers) together to get 5/5 or 1 whole.
Answer:
Option C) y = -2x - 6
Step-by-step explanation:
<u><em>The correct question is</em></u>
In the xy coordinate plane the slope of line p is 1/2 and its x-intercept is -3. Find the equation of a line that is perpendicular to p and intersects p at is x-intercept.
step 1
Find the slope of a line that is perpendicular to p
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)
we have
----> slope of line p
substitute
----> slope of the line perpendicular to p
step 2
Find the equation of the line that is perpendicular to p and intersects p at is x-intercept
we have
Find the equation of the line in point slope form
substitute
Answer:
315
Step-by-step explanation:
Area = Length x Width
Area = 21 x 15
Area = 315
