Use the linear combination method to solve the system of equations. Explain each step of your solution.

Vika [28.1K]

Answer:

1)y=-3+5x

2)y=5/2-1/2x

Step-by-step explanation:

for both equations

1) get your y by it self (subtract -5x and your new equation is now -y=-5x+3)

2)(reminder y can't be negative if it is negative) then you divide by -1 of both sides

3) your equation should now be y=5x-3

James surveyed people at school and asked whether they bring their lunch to school or buy their lunch at school more often. The

Brrunno [24]

Answer:

The correct option is 4.

Step-by-step explanation:

Given information:

Bring lunch : 46 males, 254 females

Buy lunch : 176 males, 264 females

Total number of peoples is

$46+254+176+264=740$

Total number of males is

$46+176=222$

The probability of male is

$P(Male)=\frac{Males}{Total}=\frac{222}{740} =0.3$

Since probability of males is 0.3, therefore options A and C are incorrect.

Total number of persons who buys lunch is

$176+264=440$

The probability of persons who buys lunch is

$P(\text{Buys lunch})=\frac{\text{Buys lunch}}{Total}=\frac{440}{740} =\frac{22}{37}$

We need to find the probability of P(male | buys lunch).

According to the conditional probability, we get

$P(\frac{A}{B})=\frac{P(A\cap B)}{P(B)}$

P(male | buys lunch) $=\frac{P(\text{male }\cap \text{ buys lunch})}{P(\text{buys lunch})}$

P(male | buys lunch) $=\frac{\frac{176}{740}}{\frac{22}{37}}$

P(male | buys lunch) $=\frac{2}{5}=0.4$

Therefore the correct option is 4.

Let f= {(-5,1).( - 4,0).(0,6)} Find f(0) f(0)=

sweet [91]

Given:

It is given that the coordinates of the function are $f=\{(-5,1),(-4,0),(0,6)\}$

We need to determine the value of f(0)

Value of f(0):

The value of f(0) is the value of the function when the input is 0.

We need to determine the value of f(0) when the input is x = 0

Thus, from the coordinates of the function $f=\{(-5,1),(-4,0),(0,6)\}$ , it is obvious that the input value of the function is x = 0 , then the value of the function f(0) = 6.

Thus, when the input value x = 0, the output is f(0) = 6.

Therefore, the value of f(0) = 6.
