Write the equation of a line that passes through the points (−3, 7) and (3, 3)
y=−2/3x+5

y=2/3x+1

y=−2/3x+9

y=2/3x+9

Answers

Step-by-step explanation:

You can write an equation of a line conveniently by point-slope form. It's in the form of [tex]y -a = m(x -b)[/tex] where [tex](b,a)[/tex] is the coordinates of a point that's on the line and [tex]m[/tex] is the slope of the line.

Now choose a point (It doesn't really matter which one) and plug that in the equation. I'll choose [tex](-3,7)[/tex] where [tex]a = 7[/tex] and [tex]b = -3[/tex]

[tex]y -a = m(x -b) \\ y -7 = m(x -(-3)) \\ y -7 = m(x +3)[/tex]

The next thing we have to do now is finding the slope, [tex]m[/tex], where it's equal to [tex]\frac{y_{2} -y_{1}}{x_{2} -x_{1}}\\[/tex]. I'll make [tex](-3,7)[/tex] point 1 and [tex](3,3)[/tex] point 2.

[tex]m = \frac{3 - 7}{3 -(-3)} \\ m = \frac{3 - 7}{3 +3} \\ m = \frac{-4}{6} \\ m = -\frac{2}{3}[/tex]

Now let's plug that to our equation.

[tex]y -7 = m(x +3) \\ y -7 = -\frac{2}{3}(x +3)[/tex]

Now we have the equation but out of all the choices it seemed that all of them are in slope-intercept form all you have to do now is make our equation rewrite it in slope-intercept form.

[tex]y -7 = -\frac{2}{3}(x +3)\\ y -7 = -\frac{2}{3}x -\frac{2}{3}(3) \\ y - 7 = -\frac{2}{3}x -2\\ y = -\frac{2}{3}x +5[/tex]

Answer:

[tex]y = -\frac{2}{3}x +5\\[/tex] is your equation.

how can i reduce -8/-3

Answers

Answer: there are really too many options...

Step-by-step explanation:

If you just want to keep it in simplest fraction form, the negatives cancel, giving you 8/3

But if you want to make it a mixed number, the negatives still cancel and since three goes into eight twice, with two leftover, you get 2 2/3

But if you want to make it a decimal, eight divided by three gives you 2.6666 repeating

Which angle is an exterior angle of the triangle? Triangle L M N. Angle L is 1, angle M is 2, angle N is 3. Side M N extends to form angle 4. 1 2 3 4

Answers

Answer: Angle 4

See the diagram below. The angles 1,2, and 3 are interior angles as they are inside the triangle. The exterior angle is outside the triangle, formed by extending one side out.

Angle 4 is an exterior angle of the triangle. So Option D is correct

What is an angle ?

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

Given that,

The triangle LMN,

Angle L is 1,

Angle M is 2,

Angle N is 3

It can be seen in the diagram.

The angles 1,2, and 3 are interior angles as they are inside the triangle. The exterior angle is outside the triangle, formed by extending one side out.

Hence, the exterior angle is 4

A box has a volume of 30 cubic cm. the box is filled with unit cubes, with no gaps or overlaps. each unit cube measures 1 cm in length, 1 cm in width, and 1 cm in height. how many unit cubes fill the box A:90
B:10
C:30
D:33

Answers

Answer:

C. 30.

Step-by-step explanation:

Each cube has a volume  of 1 * 1* 1 = 1 cu cm.

The answer is 30 unit cubes because 30 *1 = 30.

The box is filled with 30 unit cubes.

The formula to calculate the volume of a cube: -

For a cube with side length 'a' volume V is,

[tex]V=a^{3}[/tex] cubic units

In this question, a box has a volume of 30 cubic cm.

The box is filled with unit cubes, with each unit cube measures 1 cm in length, 1 cm in width, and 1 cm in height.

Let [tex]V_{s}[/tex] represents  the volume of each unit cube and [tex]V[/tex] represent the volume of the box.

The length of each side of a unit cube is 1 cm.

So, [tex]V_{s}=(1)^{3}[/tex]

⇒ [tex]V_{s}=1[/tex] cubic cm

Let there are n unit cubes filled in the box.

⇒ [tex]V=n\times V_{s}[/tex]

⇒ [tex]30=n\times 1[/tex]

⇒[tex]n=30[/tex]

Therefore, 30 unit cubes are filled in the box.

Hence, option C. 30 is the correct answer.

What is the equation of a line that

y = 2x + 4
c
y=-3x-2
Dy = 2x + 8
B
a
A
b
B

Answers

Answer:

B. y = 2x + 4

Step-by-step explanation:

Parallel lines will share the same slope: therefore, A and C are out ( they are the negative reciprocals of the equation's slope. The y-value from the point given is 4, meaning the y-intercept for the equation of the parallel line has to be 4 to match the criteria given in the question. So the answer is B.

We want to get a line parallel to y = 2x + 7 that passes through the point (-2, 4). We will see that the correct option is D.

Parallel lines

We define general linear equations as:

y = a*x + b

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

We know that two lines are parallel if and only if they have the same slope and different y-intercept.

So if we want to have a line parallel to y = 2*x + 7, then our line must also have a slope equal to 2, so we have:

y = 2*x + b

To find the value of b we use the fact that the line passes through (-2, 4), replacing the values of the point in the equation we get:

4 = 2*(-2) + b

4 = -4 + b

4 + 4 = b

8 = b

Then the equation for our line is:

y = 2*x + 8

Then the correct option is D.

x = 8

The value of x would be equal to 8.

We know that equation is an expression that shows the relationship between two or more numbers, variables, and a mathematical equation is a statement with two equal sides and an equal sign in between.

We are given the equation as;

3x + 10+ 2x =50

Now solve for x;
