Evaluate the expression for a =-4 5s+14

Find the product of both functions: y= 2x - 1 y = -x + 2

nata0808 [166]

Answer:

0.375

Step-by-step explanation:

1.y=2x-1

2.y=-x+2

using substitution method

1.y=2x-1

y+1=2x

the other equation where there is an x will be replaced by a the first equation

so

2.y=-(y+1)+2

y=-y-1+2

y=-y+1

y+y=1

2y=1

2y/2=1/2

y=0.5

the value of y is 0.5 the value of x would be found by taking the y and replacing it with 0.5 in any of questions one and two.

1.y(0.5)=2x-1

0.5=2x-1

0.5+1=2x

1.5=2x

1.5/2=2x/2

0.75=x

the value of y is 0.5 and x is 0.75

0.5*0.75=0.375

=0.375

Please explain how to solve step by step. Thank you.

3x-2 = 5x-14

Subtract 3x from each side:

-2 = 2x -14

Add 14 to each side:

12 = 2x

Divide both sides by 2:

x = 12/2

x = 6

The probability that a randomly selected student from the class has brown eyes , given they are male

$P(\frac{B}{M} ) = 0.3030$

Step-by-step explanation:

Explanation:-

Given data

Brown Blue Hazel Green

Females 13 4 6 9

Males 10 2 9 12

Let 'B' be the event of brown eyes

Total number of males n(M) = 33

Let B/M be the event of randomly selected student from the class has brown eyes given they are male

The probability that a randomly selected student from the class has brown eyes , given they are male

$P(\frac{B}{M} ) = \frac{n(B)}{n(M)}$

From table the brown eyes from males = 10

$P(\frac{B}{M} ) = \frac{10}{33}$

$P(\frac{B}{M} ) = 0.3030$

Final answer:-

The probability that a randomly selected student from the class has brown eyes , given they are male

$P(\frac{B}{M} ) = 0.3030$
