Solve the system using substitution. y= -6x+54 5y-x+9=0

1 answer:

8 0

Y=-6x+54

5y-x+9=0

5(-6x+54)-x+9=0

Distribute the 5 to the -6x and 54.

-30x+270-x+9=0

Then simply.

-31x+279=0

Subtract 279 from both sides.

-31x=279

x=-9

F(x) = x^2-5 g(x) = 4x - 4 Find (f-g) (5)

Tresset [83]

Answer:

The correct answer option is: 4.

Step-by-step explanation:

We are given the following two functions and we are to find the value of $( f - g ) ( 5 )$ :

$f(x) = x^2 - 5$

$g(x) = 4x - 4$

Finding $( f - g ) ( x )$ :

$( f - g ) ( x )$ $= (x^2-5)-(4x-4) = x^2-4x-5+4$

$( f - g ) ( x ) = x^2-4x-1$

So, $( f - g ) ( 5 ) = (5)^2-4(5)-1 = 4$

Fifty-five percent of the members of the junior varsity swim team wear glasses. Of the team memebers who do not wear glasses, 30

GarryVolchara [31]

the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade is 14%.

Given, the members of the junior varsity swim team wear glasses is 55%.

And the members of junior varsity swim team who do not wear glasses and in 10th grade is 30%.

Let the total no. of members be x.

So, the members of the junior varsity swim team wear glasses (55%),will be

$0.55x$ .

The total number of members not wearing glasses, will be

$x - 0.55 x = 0.45 x$ .

Now, the no. of members not wearing glasses and in 10th grade will be,

$\frac{0.45x\times30}{100} =0.135x$

We know that the probability of an event E, P(E) will be,

$P(E)=\frac{No.\ of Favourable\ outcomes}{total \ no. \ of \ outcomes}$

So, the probability for no. of members not wearing glasses and in 10th grade will be,

$P(E)=\dfrac{0.135x}{x}$

$P(E)=0.135\\\\P(E)=13.5 \%$

Hence the nearest whole percent of probability is 14%.
