What are the intercepts of x-4y=4

Mathematics
1 answer:
navik [9.2K]3 years ago
4 0

x - 4y = 4

x-intercept for y = 0

substitute y = 0:

x - 4(0) = 4

x - 0 = 4

x = 4 → (4, 0)

y-intercept for x = 0

substitute x = 0:

0 - 4y = 4

-4y = 4     <em>divide both sides by (-4)</em>

y = -1 → (0, -1)

Answer:

2) 45

3) 25

4) 50%

5) 33.3%

6) 17.6

7) 500

8) 35%

9) 60

10) 87.5%

11) 2.64

12) 25%

13) 5.7

14) 85%

16) 75%

Step-by-step explanation:

2) 9 = 20% of x

9 * 5 = 45

3) 8% of x = 2

12.5 * 2 = 25

4) 39 = x(78)

39/78 = 1/2 = 50%

5) x(36) = 12

12/36 = 1/3 = 33.3...%

6) x = 0.8(22)

22/10 = 2.2

2.2* 8 = 16 + 1.6 = 17.6

7) 55 = 0.11(x)

55/11 = 5

5 * 100 = 500

8) 7/20 = 35/100 = 35%

9) 27 = 0.45(x)

27/45 = 3/5

3/5 * 100 = 300/5 = 60

10) . 49/56 = 7/8 = 0.875 = 87.5%

11) 6/100 = 0.06

0.06 * 44 = 2.64

12) 48/192 = 6/24 = 1/4 = 25%

13) 95/100 = 0.95

0.95 * 6 = 5.40 + 0.3 = 5.7

14) 68/80 = 34/40 = 17/20 = 85%

16) 108/144 = 9/12 = 0.75 = 75%

If my answer is incorrect, pls correct me!

20=8+v i dont know how to do this
Tasya [4]
20 = 8 + v equals v = 12.

First,  subtract 8 from both sides. Your problem should look like: 20 - 8 = v
Second,  simplify 20 - 8 to get 12. Your problem should look like: 12 = v.
Third, switch sides to get v = 12, which is the correct answer.

Answer:

1. The probability that the T-shirt will be grey :-

=》

\frac{2}{20}

=》

\frac{1}{10}

=》

0.1

hence, the probability of grey t-shirt is 0.1

2. The probability that the T-shirt will not be red :-

=》

1 -  \frac{4}{20}

=》

1 -  \frac{2}{10}

=》

1 - 0.2

=》

0.8

The probability that the T-shirt will not be red is

0.8

3. He takes one of his blue T-shirts at random.

What is the probability that the T-shirt is light blue

total blue t-shirts = 5

so, the probability of choosing light blue t-shirt is

=》

\frac{1}{5}

=》

\frac{2}{10}

=》

0.2

hence, the probability of choosing light blue t-shirt is 0.2
