Answer:

slope = - [tex]\frac{2}{3}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

2x + 3y = - 12 ( subtract 2x from both sides )

3y = - 2x - 12 ( divide all terms by 3 )

y = - [tex]\frac{2}{3}[/tex] x - 4 ← in slope- intercept form

with slope m = - [tex]\frac{2}{3}[/tex]

Answer: x = 7

Step-by-step explanation:

5x + 7 = 42

We then take 7 away from both sides:

5x = 35

Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.

x = 7

Answer is 3 m/s.

The ostrich ran at a constant velocity, so it's velocity was :

[tex]velocity = \frac{distance}{time} [/tex]

It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :

[tex]distance = \frac{960 \: metres}{time} [/tex]

[tex]distance = 480 \: metres[/tex]

And the velocity is :-

[tex]velocity = \frac{480 \: metres}{160 \: seconds} [/tex]

[tex]velocity = 3 \: m/s[/tex]

Therefore, the ostrich ran at a velocity of 3 m/s .

Answer:

x = 7

Step-by-step explanation:

y = 14

14 x 2 = 28

Therefore:

3.5 x 2 = 7

Value of y is 112 when value of x is 28

Given that;

Value of y is 14 when x = 3.5

Find:

Value of y when value of x = 28

Computation:

We know that, y is directly proportional to x

So,

[tex]Value\ of\ y = 14[\frac{28}{3.5} ] \\\\Value\ of\ y = 14[8]\\\\Value\ of\ y = 112[/tex]

The bat weighs 10kg.

Two equations can be gotten from the question:

5a + 4b = 58 equation 1

4a + 5b = 50 equation 2

Where:

a = weight of bats

b = weight of balls

The two equations are simultaneous equations and would be solved using the elimination method.

In order to determine the weight of balls, take the following steps:

Multiply equation 1 by 4 and equation 2 by 5

20a + 16b = 232 equation 3

20a + 25b = 250 equation 4

Subtract equation 3 from 4

18 = 9b

Divide both sides of the equation by 9

b = 2kg

In order to determine the weight of bats, take the following steps:

Replace for b in equation 1

5a + 4(2) = 58

5a + 8 = 58

5a = 58 - 8

5a = 50

Divide both sides of the equation by 5

a = 10kg

[tex]slop = \frac{y2 - y1}{x2 - x1} = \frac{ - 4 - 1}{ - 4 - 0} = \frac{ - 5}{ - 4} = 1.25[/tex]

We are given a line and a point, I assume that we want to see if the point is on the line or not.

We will see that the point does not belong to the line.

First, let's find the equation of the line.

A general line can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through points (x₁, y₁) and (x₂, y₂), then the slope can be computed as:

[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here we know that our line passes through the points (-2, 4) and (1, -9). Then the slope is:

[tex]a = \frac{4 - (-9)}{-2 - 1} = \frac{13}{-3} = -\frac{13}{3}[/tex]

Then our line is something like:

[tex]y = -\frac{13}{3} *x + b[/tex]

To find the value of b, we can use one of the two points that we know that are on the line.

For example, the point (-2, 4) means that when x = -2, we must have y = 4.

Replacing that in the equation we get:

[tex]4 = -\frac{13}{3} *(-2) + b\\\\4 = \frac{26}{3} + b\\\\4 - \frac{26}{3} = b\\\\\frac{-14}{3} = b[/tex]

Now we can write the line equation as:

[tex]y = -\frac{13}{3} *x - \frac{14}{3}[/tex]

Now we need to see if the point (14, -6) belongs to the line.

To see this, we evaluate the line in x = 14.

[tex]y = -\frac{13}{3} *14 - \frac{14}{3} = -\frac{196}{3}[/tex]

This is different than -6, so the point does not belong to the line.

Amtrak: 80 miles in 5 hours

Metra: 30 miles in 2 hours

Which train is faster? How do you know?

[tex]\textbf{Amtrak is correct}[/tex]

Step-by-step explanation:

So First we have to figure out Has fast the trains  go in 1 hour so we are going to divide...

30 ÷ 2 =  15 Miles  (Metra can go 15 Miles in one hour)

80 ÷ by 5 = 16  (Amtrak Can go 16 Miles in one hour)

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

→ x + x + 4 = 50

→ 2x + 4 = 50

→ 2x = 50 - 4 = 46

→ x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!

Step-by-step explanation:

x + y = 50

x - y = 4

x = y + 4

let's use that as substitute in the first equation

y + 4 + y = 50

2y = 46

y = 46/2 = 23

=>

x = y + 4 = 23 + 4 = 27

the 2 numbers are 23 and 27.
