C. - 2
D. 2

Answer:

1.0.73

2.0.05

you are welcome

Answer:

1 and 2

Step-by-step explanation:

slope is 1

y intercept is 2

basically base it off the equation y = mx + b

the m is the slope, but since in this case there is no number before x, you just put 1, since 1 times x is just x and thats why its left out

the b is the y intercept, so in this case its 2

Answer:

28

Step-by-step explanation:

Well we know that in a day there are 24 hrs so in 4 days there will be 96 hrs

so the car travelled 2686 miles in 96 hours

2686/96= 27.9791666667

So the car's average speed is about 28

Answer:

6.3

Step-by-step explanation:

8.5 - (-4.8)

Let's focus on - (-4.8)

if a negative number is subtracted, it reverses itself

In other words, if a negative number is being subtracted, it is the same as being added as a positive number

So we change the equation to

8.5 + 4.8 = 13.3

Now we subtract 7 from 13.3

Since positive 7 is being subtracted, the rule for -4.8 does not apply to it

13.3 - 7 = 6.3

Answer:

2.36 * 10^13 miles

Step-by-step explanation:

Given that :

Proxima centauri is at a distance of 4.24 light years away from the sun.

Distance in miles of Proxima centauri from the sun ;

1 light year = 5.9 * 10^12 miles

Number of light years from the sun * 5.9 * 10^12

= 4 * (5.9 * 10^12)

= 23.6 * 10^12 miles

= 2.36 * 10^13 miles

Answer:

-9°F

Step-by-step explanation:

If we have a horizontal line in which the zero is in the middle, the positive numbers are on the right and the negative numbers are on the right, we would see that -9°F is further than 6°F. Even though -9°F is a smaller temperature, it is still further away from the zero.

Answer: -6

Step-by-step explanation: 7 + -6 = 1

:\

Answer:

x= -6

Step-by-step explanation:

x+7=1

1-7= - 6

SO , -6+7= 1

First you add 3x+x because they are like terms.

3x+x-7=10  

Your New Simplified Equation:

4x-7=10  

Now, you have to take out the -7 by adding a positive 7. Also you                          have to add +7 on the other side so add 7 to 10.

Your New Simplified Equation:

4x=17      Now, you divide both sides by 4.

Your New Simplified Equation:

x= 17/4 So, that's your answer :)

Answer:

Tn = 8n - 2

Step-by-step explanation:

Given the arithmetic sequence

6, 14, 22, 30, 38

The nth term is expressed as;

Tn = a +(n-1)d

a is the first term = 6

d is the common difference = 14 - 6 = 22 - 14 = 8

Substitute into the formula;

Tn = 6 + (n-1)(8)

Tn = 6 + 8n-8

Tn = 8n - 2

Hence the nth term of the sequence is 8n-2

Answer:

y =3 x

Step-by-step explanation:

The standard equation of a line in point slope form is expressed as;

y -y0 = m(x-x0)

m is the slope

(x0, y0) is the point on the line

Given the line 3x - y = 5

Get the slope

- y = -3x + 5

y = 3x - 5

Slope m  = 3

Substitute m = 3 and (-1, -5) into the given formula

y - (-5) = 3(x-(-1))

y+5 = 3(x+1)

y + 3 = 3x+3

y = 3x + 3 - 3

y = 3x

Hence the equation in slope intercept form is y =3 x

Answer:

right triangle it is because if u make a graph and put the points u would get a right isosclses triangle

Step-by-step explanation:

The triangle ABC with verticies A(3, 3), B(6, 9) and C(6, -3) is an isosceles triangle.

If a² + b² < c² then it is an acute angle triangle.

If a² + b² = c² then it is a right-angle triangle.

If a² + b² ≥ c² then it is an obtuse angle triangle.

Given, A ΔABC with verticies A(3, 3), B(6, 9) and C(6, -3).

We know the distance formula [tex]D = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2[/tex].

From this we find AB = √45 units, BC = 12 units and AC = √45 units.

Now, this is an isosceles triangle with two equal sides of √45 units.
