The line with slope m that contains the point (x1, y1) can be described by the equation

y − y1 = m(x − x1). In a real-world linear situation, you may have information that represents two points on the line. You can write an equation in point-slope form that represents the situation and use that equation to solve a problem.

Let x represent the number of days since the ship left port and y represent the number of gallons of water.

Two points on the line are (8,3240) and (1, 3555).

m =  

3555 − 3240

1 − 8

 =  

315

−7

 = −45

y − y1 = m(x − x1) Point-slope form.

y − 3555 = −45(x − 1) or y − 3240 = −45(x − 8)

y − 3555 = −45(60 − 1) Substitute for x.

y − 3555 = −2655 Simplify the right side.

y = 900 Solve for y.

900 gallons of water will be left after 60 days.

Hope this helped! (I didn't do it sooner cause I just did the quiz lol)

The equation of the function, in point-slope form, is given by:

[tex]y - 3555 = -45(x - 1)[/tex]

The amount of water left in the ship after 60 days is of 900 cubic units.

A line, in point-slope form, is represented by the following equation:

[tex]y - y_0 = m(x - x_0)[/tex]

In which:

We have two points: (1, 3555) and (8,3240).

[tex]m = \frac{3240 - 3555}{8 - 1} = -45[/tex]

Then

[tex]y - y_0 = m(x - x_0)[/tex]

[tex]y - 3555 = -45(x - 1)[/tex]

The amount after 60 days is y when x = 60, thus:

[tex]y - 3555 = -45(60 - 1)[/tex]

[tex]y = 900[/tex]

The amount of water left in the ship after 60 days is of 900 cubic units.

Answer:

y-9=-1(x+3)

Step-by-step explanation:

The formula for point slope is y2-y1=m(x2-x1). So, we can use the values of the given points to solve the equation for m, or, the slope. We get an equation with the result of 2-9=m(4+3), which gives us the slope as -1. Now, substitute your xy values back in, to get the equation

Answer:

thirteen hundredths=13/100

one hundred thirty thousandths=130/1000

cancelling by 10 this is =13/100

hence the question

Step-by-step explanation:

13/100 is equivalent to 130/1000 because if you simplify 130/1000 it becomes 13/100.

You simplify 130/1000 by dividing both sides by 10. 130 divided by 10 is 13, and 1000 divided by 10 is 100.

Answer:

B

Step-by-step explanation:

Expanding the factors using FOIL

A

(x - 3)(x + 4)

= x² + 4x - 3x - 12

= x² + x - 12 ← a trinomial

B

(x + 3)(x - 3)

= x² - 3x + 3x - 9

= x² - 9 ← a binomial

C

(x - 3)² = (x - 3)(x - 3) = x² - 6x + 9 ← a trinomial

Number of drink

Computation:

Assume;

Number of drink = x

So,

4.25x ≤ 50

x ≤ 11.76

so,

Number of drink = 11

Hope This Helps :)

Answer:

x = 4

Step-by-step explanation:

Step 1: Write equation

-3x + 20 = 8

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

-3(4) + 20 = 8

-12 + 20 = 8

8 = 8

Given:

Four equations are

[tex] 7 x + 1 = 7 x+ 1[/tex]

[tex]3 x + 2 = 3 x-2[/tex]

[tex]4 x + 1 = 3 x + 8[/tex]

[tex]-2x-1 = -2 x-1[/tex]

To find:

Without solving which equation has no solution.

Solution:

We know that, in an equation

1. No solution : When variable terms are same but constants are different.

2. Unique solution : When variable terms are different.

3. infinitely many solution : When variable terms and constants are same.

In first and fourth equations, terms on left sides are equal to the terms on the right side. So, LHS = RHS for any value of x.

Therefore, these two equations (first and fourth) have infinitely many solutions.

In second equation, variable terms are same on both sides, but the constants are difference. So, LHS ≠ RHS for any value of x.

Therefore, the second has no solutions.

In third equation, coefficient of x are difference on both sides.

So, this equation has unique solution.

Therefore, Jubal's equations [tex]3 x + 2 = 3 x-2[/tex] has no solution. Hence, the correct option is B.
