Answer:

y > -7

Step-by-step explanation:

multiply both sides by -1, remember to reverse the inequality when multiplying (or dividing by -1 on both sides

Hence:

-y (-1) > 7(-1) -----> remember to reverse inequality

y > -7 (answer)

If y varies directly as z and inversely as x and y = –18 and z = 3 when x = 6, find y when x = 5 and z = –5.

JulijaS [17]

Answer:

y = 36

Step-by-step explanation:

Given y varies directly as z and inversely as x then the equation relating them is

y = $\frac{kz}{x}$ ← k is the constant of variation

To find k use the condition y = - 18, z = 3 when x = 6 , then

- 18 = $\frac{3k}{6}$ ( multiply both sides by 6 )

- 108 = 3k ( divide both sides by 3 )

- 36 = k

y = $\frac{-36z}{x}$ ← equation of variation

When x = 5 and z = - 5, then

y = $\frac{-36(-5)}{5}$ = $\frac{180}{5}$ = 36

Find the value for the following determinant.<br><br><br><br> -32<br> -42<br> 42

hjlf

Using the rule for 2x2 matrices,

$\begin{vmatrix}a&b\\c&d\end{vmatrix}=ad-bc$

the determinant for your matrix is

$\begin{vmatrix}5&-4\\8&2\end{vmatrix}=5\times2-(-4)\times8=42$

I to the exponent of 65

larisa86 [58]

Answer:

Step-by-step explanation:

A= 1 * 1 = 2

A2 = 1 * (1 * 1)

A2 = 1 * 1

A2 = 1

a3 = 1 * 1 * (1 * 1)

a3 = 1 *1 * 1

a3 = 1 * (1*1)

a3 = 1* 1

a3 = 1

You keep on going in this manner until you hit 1^65 = 1

The only thing you have to accept is that (1 * 1) = 1

What is the minimum number of 60 passenger buses needed to transport 200 students?

astraxan [27]

The answer is 4. 3 busses would carry 180, so you gotta have that one extra bus. The question is set up to kind of throw you off but it's quite simple
