Hi:) I need help with part 9(ii) ? Thanks :)!
Goshia [24]

Answer:

see explanation

Step-by-step explanation:

Given

2BD = 7BT , then

2(d - b ) = 7(t - b) ← distribute both sides

2d - 2b = 7t - 7b ( add 7b to both sides )

2d + 5b = 7t, thus

2\left[\begin{array}{ccc}10.5\\10\\\end{array}\right] + 5\left[\begin{array}{ccc}0\\3\\\end{array}\right] = 7t

\left[\begin{array}{ccc}21\\20\\\end{array}\right] + \left[\begin{array}{ccc}0\\15\\\end{array}\right] = 7t

\left[\begin{array}{ccc}21\\35\\\end{array}\right] = 7t , thus

t = \frac{1}{7}\left[\begin{array}{ccc}21\\35\\\end{array}\right] = \left[\begin{array}{ccc}3\\5\\\end{array}\right]

Hence T = (3, 5 )

How do you solve z/-4&lt;2
ohaa [14]
Z / -4 < 2....multiply both sides by -4, cancelling out the -4 on the left. And dont forget to change the inequality sign because of multiplying by a negative.

z > 2 * -4
z > -8
