Hey there! :)

Answer:

(30, 0).

Step-by-step explanation:

Solve for the x-intercept, or zero of the equation by setting the equation equal to 0:

y = -2/5x + 12 becomes:

0 = -2/5x + 12

Subtract both sides by 12:

-12 = -2/5x

Divide both sides by -2/5:

-12 (-5/2) = -2/5x (-5/2)

30 = x.

Therefore, the x-intercept is at (30, 0).

Answer:

(30,0)

Step-by-step explanation:

y=0

2x=12*5

2x=60

x=60/2

x=30

A bag contains 19 red,15 yellow and 14 blue marbles. what is the probability of pulling out a blue marble, followed by a red mar

irina1246 [14]

Answer:

133/1152

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

19+15+14 = 48 marbles

Of which 19 are red, 15 are yellow and 14 are blue.

What is the probability of pulling out a blue marble, followed by a red marble, if you replace the blue marble first

Blue marble

48 marbles, of which 14 are blue.

So $P_{A} = \frac{14}{48} = \frac{7}{24}$

Red marble

48 marbles, of which 19 are red.

So $P_{B} = \frac{19}{48}$

Both:

$P = P_{A} \times P_{B} = \frac{7}{24} \times \frac{19}{48} = \frac{133}{1152}$

So the correct answer is:

133/1152

kvasek [131]

5x + 7 = 27

5x = 27 - 7
5x = 20
x = 20 ÷ 5
x = 4

2p - 15 = 35

2p = 35 + 15
2p = 50
p = 50/2
p = 25

Answer:

Step-by-step explanation:

a number expressed in standard form is

a × $10^{n}$ : 1 ≤ a < 10 and n is an integer

given

(7.5 × $10^{7}$ )(2 × 10³)

= 7.5 × 2 × $10^{(7+3)}$

= 15 × $10^{10}$

= 1.5 × $10^{1}$ × $10^{10}$

= 1.5 × $10^{(1+10)}$

= 1.5 × $10^{11}$
