F(x)=6x+7, evaluate f(x)=49

Mathematics
1 answer:
elixir [45]3 years ago
6 0

Answer:

X=7

Step-by-step explanation:

Since we have the function F(x)=6x+7, and we are given f(x)=49, we know that 6x+7=49.

Thus, solve for x

6x+7=49

6x=42

x=42/6

x=7

Hope this helps :)

You roll two fair dice, one green and one red. (a) Are the outcomes on the dice independent? Yes No (b) Find P(1 on green die an
ASHA 777 [7]

Answer:

a

  Yes

b

 P(1 \& 5) = \frac{1}{36}

c

 P(5 \& 1) = \frac{1}{36}

d

 P(5 \& 1 | 1\& 5  ) = \frac{1}{18}

Step-by-step explanation:

From the question we are told that

     Two fair dice, one green and one red were rolled

Generally the  outcomes on the dice independent because the outcome on the first dice is not affected by the second die

Generally the  probability of getting a 1  on a dice rolled is  P(1) =  \frac{1}{6}

the  probability of getting a 5 on a dice rolled is  P(5) =  \frac{1}{6}

Generally the probability of P(1 on green die and 5 on red die) is mathematically represented as

         P(1 \& 5) = \frac{1}{6}  *\frac{1}{6}

         P(1 \& 5) = \frac{1}{36}

Generally the probability of P(5 on green die and 1 on red die) is mathematically represented as

          P(5 \& 1) = \frac{1}{6}  *\frac{1}{6}

         P(5 \& 1) = \frac{1}{36}

Generally the probability of P((1 on green die and 5 on red die) or (5 on green die and 1 on red die)) is mathematically represented as

          P(5 \& 1 | 1\& 5  ) = \frac{1}{36} + \frac{1}{36}

         P(5 \& 1 | 1\& 5  ) = \frac{1}{18}

The sum of two numbers is 200 and the two numbers are in a ratio of 4:6 find the larger number
devlian [24]
X = 1st number
y = 2nd number

x + y = 200
x : y = 4 : 6

ok! let's substitute numbers!

4 * 10 : 6 * 10

40 : 60

40 + 60 = 200

100 ≠ 200

Too small!

That is exactly two times smaller than 200 so let's try 2 times greater than multiplying by 10

4 * 20 : 6 * 20
80 : 120

80 + 120 = 200

200 = 200

Now it says to find the larger number. Which is y.

x :y = 4 : 6 = 80 : 120

so, y is 120

y = 120

Answer : y = 120. The larger number is 120.
