Find the y and the x intercepts of the graph of the equation of y=3x+1

BaLLatris [955]

Answer:

x-intercept ⇨ -1/3

y-intercept ⇨ 1

Step-by-step explanation:

⟺ Finding the x-intercept, substitute y = 0

$y=3x+1\\0=3x+1\\3x+1=0\\$

Move 1 to subtract the another side.

$3x=-1$

Then move 3 to divide -1, leaving only x as a subject since we want to find the x-intercept.

$x=-\frac{1}{3}$ #

⟺ Finding the y-intercept, substitute x = 0

$y=3x+1\\y=3(0)+1\\y=0+1$

$y=1$ #

Tips:

Here's the tips about finding the intercepts of the graph.

⟺ For x-intercept, It's like solving an equation to find the x-term.

⟺ For y-intercept, It's like using the constant to answer.

As for y = mx+b where m = slope and b = y-intercept.

For a linear function, It's not necessary to substitute x = 0 just to find y-intercept as we can answer the constant as our y-intercept.

On a certain route, an airline carries 8000 passengers per month, each paying $70.A market survey indicates that for each $1

son4ous [18]

Answer:

The maximum revenue is $661,250.

Step-by-step explanation:

The total revenue (R) is the product between the number of passengers (N) and the price of each ticket (P), so the inicial revenue is:

R = N * P = 8000 * 70 = $560,000

For each 1$ increase in the ticket, the airline loses 50 passengers, so if we call "x" the increase in the ticket price, we have that the revenue equation will be:

R = (8000-50*x) * (70+x) = 560000 + 8000*x - 50*70*x -50x2

R = -50*x2 + 4500*x + 560000

The value of x that gives the maximum value of a quadratic function is found using the formula:

x = -b/2a

where a and b are coefficients of the quadratic equation (in our case, a = -50 and b = 4500)

So the value of x that gives the maximum revenue is:

x = -4500 / (-100) = 45

Using this value in the revenue equation, we have that the maximum R is:

R = -50*45^2 + 4500*45 + 560000 = $661,250

(To get this revenue, the ticket will cost 70+45 = $115 and there will be 8000-50*45 = 5750 passengers)

Help I don’t understand this

Ganezh [65]

Answer:

Step-by-step explanation:

they are opposite angles, so we put them equal to each other.

25.

6a+10= 130

6a=120 a=20 so now we plug it in 6(20) +10= 130

26. 4a-4=2a+30

2a=34 a=17 sso now we plug in 4(17)-4= 64 2(17)+30= 64

27. 6y+1=4y+9 2x-5=x+7

2y=8 x=2

y=4

now plug in 6(4)+1=25 4(4)+9=25 2(2)-5= -1 (2)+7=9
