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.

3x + 10+ 2x =50 isks
Answers
Answer:
x = 8Step-by-step explanation:
3x + 10+ 2x =50
5x = 50 - 10
x = 40/5
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;
3x + 10+ 2x =50
Combine like terms;
5x = 50 - 10
x = 40/5
x = 8
The solution will be 8.

What is the equation of a line that
is parallel to the line y = 2x + 7 and

A y=- 2x+3
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.

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.

Answers
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
