Answer:
BK=39/7
Step-by-step explanation:
because NQZ~CBK
so BK/QZ = TZ/KF
(4x+1)/(2x+7) = 27/45 = 3/5
5(4x+1) = 3(2x+7)
20x + 5 = 6x + 21
14x = 16
x = 8/7
=> BK = 4(8/7)+1 = 39/7
Answer:
y = 9
Step-by-step explanation:
We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.
Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
×
= 
Given
×
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
