I think not fpr sure though
Answer:
x = 2
Step-by-step explanation:
<em>Here's</em><em> your</em><em> solution</em>
=> we know that tangents from a point to a common circle are equal
=> so, ST = SU
=> 7x - 3 = 5x + 1
=> 7x - 5x = 1 + 3
=> 2x = 4
=> x = 4/2
=> x = 2
hope it helps
Step-by-step explanation:
the products is the 2 parts of the segment lines are the same.
so,
5×8 = 4x
is correct (the second option).
which means
40 = 4x
x = 10
Answer:
-17
Step-by-step explanation:
8x -2y= 12
<em>Divide</em><em> </em><em>the</em><em> </em><em>whole</em><em> </em><em>equation</em><em> </em><em>by</em><em> </em><em>2</em><em>:</em>
4x -y= 6
<em>Rewrite the equation into the slope-intercept form (y=mx+c, where m is the gradient while c is the y-intercept).</em>
-y= -4x +6
y= 4x -6
Thus, gradient of given line= 4.
Since parallel lines have the same gradient, gradient of line= 4.
y= 4x +c
<em>To find the y-intercept of the lone, substitute a pair of coordinates.</em>
When x=5, y=3,
3= 4(5) +c
3= 20 +c
c= 3 -20
c= -17
Thus, the y-intercept of the line is -17.
