Answer:

Following equations represents a linear function:

y = 6x

y = 4x - √2

x – 4y = 6

Step-by-step explanation:

We know that a linear function is of the form

where m is the rate of change or slope and b is the y-intercept.

Please note that y = mx+b represents a straight line because the degree of a linear function is always 1.

Now, let us check whether the given functions represent the linear functions or not.

Checking y = 6x

y = 6x

gtnhenbr [62]

a + m = 30
a = m - 8

(m - 8) + m = 30
2m - 8 = 30
2m = 30 + 8
2m = 38
m = 38/2
m = 19

a = m - 8
a = 19 - 8
a = 11

so Amy has $11 and Maria has $ 19

a bag contains 5 red skittles, 3 purple skittles, and 2 orange skittles.A skittle is removed and not replaced, then another skit

dybincka [34]

The probability of two independant events $P_a$ and $P_b$ can be found by multiplying the individual probabilities like so:
$P_t=P_{a}*P_b$

For each individual probability we can find the answer via a simplfied representation:
$P_x = \frac{wanted}{total}$

For the first skittle (red) we have:
$P_{red} = \frac{red}{total}=\frac{5}{10}=0.5$

For the second skittle (orange) we have:
$P_{orange} = \frac{2}{9} = 0.2222...$
**(Notice that the total is now NINE since we didn't put the first red one back in the bag.)

So:
$P_{total} = P_{red} \times P_{orange}$
$P_{total} = \frac{5}{10} \times \frac{2}{9}$
$P_{total} = \frac{10}{90}=\frac{1}{9} \approx 0.1111 \approx 11.11\%$
