Y = number of songs she can still download
y + 8 ≤ 11
- 8 -8
------------
y ≤ 3
She can only download 3 more songs
No way to know what reasons you're supposed to choose from...
By definition of tangent,
The angle sum identities give
, so we can cancel those terms to get
as required.
Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = = = -
The y- intercept is where the line crosses the y- axis
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
(b)
y = - x + 3 ← equation of line
Only 1 solution : when u calculate it the only answer you get is -1. Hope this helps
Answer:
<u>SOLUTION
</u>
<u>GIVEN:</u>
Two straight lines have equations y=px+4 and py=qx−7, where p and q are constants.
The two lines meet at the point (3,1)
<u />
<u>TO DETERMINE</u>
The value of q
<u>EVALUATION</u>
Here the given equation of the lines are
Now the two lines meet at the point (3,1)
Since equation (1) passes through the point (3,1)
Again Equation (2) passes through the point (3,1)
<em>FINAL ANSWER</em>
Hence the required value of q = 2
