The points (3,2) and (-2,-3) are solutions to a system of two linear equations. What MUST be true about the two linear equations?
A. The equations create perpendicular line
B. The equations create the same line
C. The equations create parallel lines
D. The equations create horizontal lines
PLEASE HELP ♡
Answer:
B. The equations create the same line
Step-by-step explanation:
A system of two linear equations have either 0, 1 or infinite solutions.
Since you have 2 solutions, there have to be infinitely many more. That means you have written the same line twice. The solution is B.
Alternatively, you can think that given two points, there is one and only one line that passes through both.

Erica and Amy started biking in the opposite directions at the same time from the same place. Erica biked at a speed of 6 meters per second and Amy biked at a speed of 4 meters per second. How soon were they exactly 1km apart?
Answer:
Since they are moving in opposite directions, this is the same as Amy staying still and Erica biking at 10 meters per second away from her.To travel 1km = 1000m at 10 meters per second, you need 1000/10 = 100

Answer:
2, 14, 26Step-by-step explanation:
The rule is:
y = 6x - 4We have x- values of 1, 3, 10 and need to find the y-values.
Substitute the values of x into the rule to find the corresponding values of y:
y = 6*1 - 4 = 6 - 4 = 2y = 6*3 - 4 = 18 - 4 = 14y = 10*3 - 4 = 30 - 4 = 26We need y values of 1,3,10
y=6x-4#1
y=6(1)-4=6-4=2#3
y=6(3)-4=18-4=14#10
y=6(10)-4=60-4=56

17. Write an equation in slope-
intercept form of a line with no
slope and passes through the
point (4,-10).
Check the picture below.
the only equation form available to it is the one you see in the picture.
why it has no slope? well, if we pick any two points off of it to get its slope, we'll come back with "undefined", or namely a division by 0, and that's true for all vertical lines.
Enter the equation of the following using line in slope-intercept form. Two points on the line: (4, -2) and (-2, 4).
[tex](\stackrel{x_1}{4}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{-2}~,~\stackrel{y_2}{4}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{4}-\stackrel{y1}{(-2)}}}{\underset{run} {\underset{x_2}{-2}-\underset{x_1}{4}}}\implies \cfrac{4+2}{-6}\implies \cfrac{6}{-6}\implies -1[/tex]
[tex]\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-2)}=\stackrel{m}{-1}(x-\stackrel{x_1}{4}) \\\\\\ y+2=-x+4\implies y=-x+2[/tex]

The points (0,0), (3, 3), and (0,6) are three vertices of a square. What are the coordinates of the fourth vertex of the square?
O B. (2,3)
O A. (0, 3)
OD. (4,3)
O C. (3, 3)
Answer:
Step-by-step explanation:
let 4th vertex be (x,y)
midpoint of diagonal is same.
[tex]\frac{0+0}{2} =\frac{3+x}{2}\\\\3+x=0\\ x=-3\\\frac{0+6}{2} = \frac{3+y}{2} \\3+y=0+6\\y=6-3\\=3[/tex]
so 4th vertex is (-3,3)
Can the three numbers be the measures of the sides of a triangle? 8, 2, 8 *
Step-by-step explanation:
yes, it would be an isoceles triangle (with 2 sides being equally long).
it would be a reissue high and narrow triangle, with the very short side (2) connecting the 2 sides of 8.
in general, 3 lines can only make a triangle, if the sum of lengths of any pair of these lines is always longer than the third line.
in our case :
8+2 > 8 true
8+8 > 2 true
so, yes, they can be a triangle.
example for 3 sides not making a triangle :
2, 3, 6
as
2+3 < 6

Give your answer as an improper fraction in its simplest form.
Answer:
[tex]-\frac{13}{4}[/tex]
Step-by-step explanation:
r = 4x + 6y
11 = 4x + (6 x 4)
11 = 4x + 24
(im gonna flip it around because it looks better for me, you dont have to)
4x + 24 = 11 _(minus 24 from both sides)
4x = -13 _(divide both sides by 4)
x = [tex]-\frac{13}{4}[/tex]
Find the measure of the missing ANGLE.
35 degrees
40 degrees
52 degrees
55 degrees
Answer:
m<G = 55°
Step-by-step explanation:
m<G = (1/2)[m(arc)LE - m(arc)HF]
m<G = (1/2)[150° - 40°)
m<G = 110°/2
m<G = 55°

1 cube = 6 Faces
2 cubes = 10 Faces
7 cubes = 36 Faces
2÷7 = 3 × 10 = 30 + 6 = 36
The Answer is 36
Answer:
2 cubes = 10 faces
3 cubes = 14 faces
4 cubes = 18 faces
5 cubes = 22 faces
6 cubes = 26 faces
7 cubes = 30 faces
10 faces = 2 cubes
14 faces = 3 cubes
18 faces = 4 cubes
Step-by-step explanation:
We know that 1 cube shows 6 faces, and 2 cubes shows 10 faces. With 3 cubes, it shows 14 faces.
With this pattern, we can conclude that
f(x) = 2 + 4x
f(x) is a function for where f is the value of faces and x is the amount of cubes connected.
To find the amount of faces for the cubes used
f(2) = 2 + 4(2) = 2 + 8 = 10
f(3) = 2 + 4(3) = 2 + 12 = 14
f(4) = 2 + 4(4) = 2 + 16 = 18
f(5) = 2 + 4(5) = 2 + 20 = 22
f(6) = 2 + 4(6) = 2 + 24 = 26
f(7) = 2 + 4(7) = 2 + 28 = 30
For the amount of cubes used given the amount of faces
10 = 2 + 4x
-2 -2
8/4 = 4x/4
2 = x
x= 2
14 = 2 + 4x
-2 -2
12/4 = 4x/4
3 = x
x = 3
18 = 2 + 4x
-2 -2
16/4 = 4x/4
4 = x
x = 4
