The solution is x = 4 and y = -1

Step-by-step explanation:

The system of equation is:

  • y = \frac{1}{2} x - 3
  • y = x - 5

To solve it using the elimination method do that

∵ y = \frac{1}{2} x - 3 ⇒ (1)

∵ y = x - 5 ⇒ (2)

- Subtract equation (1) from equation (2) to eliminate y

∵ y - y = (x - \frac{1}{2} x) - 5 - (-3)

- Remember (-)(-) = (+)

∴ 0 = \frac{1}{2} x - 5 + 3

∴ 0 = \frac{1}{2} x - 2

- Add 2 to both sides

∴ 2 = \frac{1}{2} x

- Multiply both sides by 2

∴ 4 = x

∴ x = 4

- Substitute the value of x in equation (1) or (2) to find y

∵ y = 4 - 5

∴ y = -1

The solution is x = 4 and y = -1

Write your answer with no spaces and any fraction with “/“
Archy [21]

Answer:

The slope is 1/2

Step-by-step explanation:

Hi!

Disclaimer: Just for this response, I'm going to write it the same way you write a fraction out on paper just so it's easier to see.

First, you plot the two coordinates on the graph:

(0,0) and (2,1)

The formula for slope is \frac{y1 - y2}{x1 - x2}

Now we plug in numbers accordingly:

\frac{0 - 1}{0 - 2}

Simplify:

\frac{-1}{-2} \\

Simplify:

\frac{1}{2}

Which of the following represents the zeros of f(x) = 6x3 + 25x2 − 24x + 5?
cestrela7 [59]
F(-5) = 6(-5)^3 + 24(-5)^2 - 24(-5) + 5 =  0
so x = -5 is one zero.

Suppose four students miss an exam. They tell their instructor that they were carpooling to school together on the day of the ex
tia_tia [17]

Answer:

The probability they each indicate the same tire is \frac{1}{64}=0.02

Step-by-step explanation:

There will be 4 cases involved as there are 4 tires.

Probability of choosing front left tire is \frac{1}{4} as there are a total of 4 tires and we need to choose 1.

Now, if all the four students chose the front left tire then the probability is the product of individual probabilities.

Therefore, probability that all 4 students chooses front left tire is:

P(fl)=(\frac{1}{4})^4

Similarly, the probabilities of choosing the remaining 3 tires by all the students would be:

P(fr)=(\frac{1}{4})^4, P(rl)=(\frac{1}{4})^4, P(rr)=(\frac{1}{4})^4

Therefore, the probability that they indicate the same tire is the sum of all these probabilities.

P(\textrm{same tire by all})=P(fl)+P(fr)+P(rl)+P(rr)\\ P(\textrm{same tire by all})=(\frac{1}{4})^4\times 4\\ P(\textrm{same tire by all})=\frac{4}{4^4}=\frac{1}{4^3}=\frac{1}{64}=0.02
