Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)

Answers

Answer: y = -3.5x - 4.5

suppose: the equation of the line is y = ax + b ( a ≠ 0 )

because the line passes through (-2;2.5) => 2.5 = -2a + b

the line passes though (0;-4.5) => -4.5 = b

=> b = -4.5

   2.5 = -2a + b

=> a = -3.5

    b = -4.5

=> the equation of the line is y = -3.5x - 4.5

Step-by-step explanation:

The equation Of the line is y =-3.5x-4.5

Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour

Answers

Answer:

Mario's unit rate is 5/1

Step-by-step explanation:

We know that Mario walks 5/6 miles per 10 minutes.

We need to find out how many miles Mario walks in 60 minutes (1 hour).

10 * 6 = 60. Which means that we must multiply 5/6 by 6.

[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]

30/6 = 5

Mario walks 5 miles per hour.

To put this in to a unit rate we must put this is a fraction:

[tex]\frac{Miles}{Hour}[/tex]

Substitute:

5/1

Answer:

Mario's unit rate is given by 900 miles/hour

Step-by-step explanation:

We have been given that Mario walked at a rate of 2/3 miles every 10 minutes

We have the relation between speed, time and distance, which is given by

speed = distance/Time

we have,

distance = 2/3 miles

Time = 10 minutes

On substituting these values in above formula, we got

speed 2/3 /10

speed 2/10.3

We have to find the unit rate in mile per hour, so we need to multiply it by 60

Thus, unit rate is given by

1/15 X 60

= 4 miles/hour

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

5x - 2w + t = 0

Solve for x.

5x - 2w + t = 0

5x = 2w - t

x = (2w - t)/5

Solve for w.

5x - 2w + t = 0

5x + t = 2w

w = (5x + t)/2

Solve for t.

5x - 2w + t = 0

t = 2w - 5x

Thus,

The value of x, w, and t is given above.

It takes Austin 8 hours longer than Elliott to construct a wooden chair in shop class. When the classmates work together, they can complete one chair in 3 hours. This situation can be represented by this expression, where t is the amount of time, in hours, it takes Elliott to complete a chair on his own.

Answers

The equivalent expression obtained using the least common multiple concept is [tex] \frac{6t + 24}{t^{2} +8}[/tex]

To solve, we need to obtain the L. C. M of the denominator values :

The L. C. M of t and t + 8 = [tex] t^{2} + 8t[/tex]

Hence,

[tex]\frac{3}{t} + \frac{3}{t+8} = \frac{6t + 24}{t^{2} +8}[/tex]

This table represents the number of ounces, u, a kitten grows after w, weeks. When graphed, all of the points in the table lie on the same line. What is the slope and y-intercept of the line? slope=−23, y-intercept=−0.2 slope=32, y-intercept = 3 slope=23, y-intercept=−0.2 slope=−32, y-intercept = 3

Answers

Using the slope and intercept formula, the slope and y - intercept values of the graphed data are 3/2 and 3 respectively

Given the data :

Weeks, w ___ Weight in ounces, u

0 __________ 3

3 _________ 7.5

6 __________12

9 _________16.5

The y - intercept :

This is the value of y when the value of x = 0

From the table given, the initial weight of the kitten (weight at week 0) = 3 ounces

Hence, the intercept is 3 ounces.

2.)

The slope :

Slope = Rise / Run

Rise = y2 - y1 = (16.5 - 3) = 13.5

Run = x2 - x1 = 9 - 0 = 9

Slope = 13.5 / 9 = 1.5

Therefore, the slope is 1.5
