solve the system through elimination
Answer:
x=3
y=1
Step-by-step explanation:
-2x - 7y = -13
3x + 6y = 15
3(-2x - 7y = -13) = -6x - 21y = -39
2(3x + 6y = 15) = 6x + 12y = 30
-6x - 21y = -39
---------------------- The -6x and 6x cancel out, 12 - 21 is equal to 9, 30 - 39 = -9
6x + 12y = 30
Therefore, you can say that -9y = -9 so y = 1
FInally, plug that back into either one of the original equations:
3x + 6(1) =15
3x = 9
x = 3
State the slope and y-intercept of the graph of y = 1/5 x – 7

The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.
Step-by-step explanation:
The general equation of the circunferece is defined by the following formula:
[tex]x^{2}+y^{2}+A\cdot x + B\cdot y + C = 0[/tex] (1)
We can determine the value of the coefficients by knowing three distinct points: [tex](x_{1}, y_{1}) = (3,0)[/tex], [tex](x_{2},y_{2}) = (5,-2)[/tex], [tex](x_{3},y_{3}) = (1, -2)[/tex]
The system of linear equations is:
[tex]3\cdot A + C = -9[/tex] (2)
[tex]5\cdot A -2\cdot B + C = -29[/tex] (3)
[tex]A -2\cdot B + C = -5[/tex] (4)
The solution of this system is: [tex]A = -6[/tex], [tex]B = 4[/tex], [tex]C = 9[/tex].
The circunference is represented by the equation is [tex]x^{2}+y^{2}-6\cdot x +4\cdot y +9=0[/tex].
The graph of this function is presented in the attachment.

Find the volume of a cube with a side length of 14.4 m, to the nearest tenth of a cubic meter (if necessary).
Answer: 2,986 m³
Step-by-step explanation: to find the volume, you multiply the length, width , and height. since we're told this is a cube, we know that all sides are congruent, so you do 14.4 x 14.4 x 14.4 which equals about 2985.98. when rounding the solution to the nearest tenths, the answer becomes 2986 m³
If the edge length of the cube is 14.4 meters. Then the volume of the cube will be 2986 m³
What is a volume of a cube?Suppose that: The side length of the considered cube is L units. Then, we get:
Volume of that cube = L³ cubic units.
The edge length of the cube is 14.4 meters. Then the volume of the cube will be
Volume = 14.4³
Volume = 2985.98
Volume ≅ 2986 m³

What is the range of y = x 2 − 1 , given a domain of {–2, –1, 0, 1, 2}
The range of the function y = x² - 1 is {- 1, 0, 3}.
What is the domain and range of a function?Suppose we have an ordered pair (x, y) then the domain of the function is the set of values of x and the range is the set of values of y for which x is defined.
Given, A function y = x² - 1.
The set of domains is {- 2, - 1, 0, 1, 2}.
The set of co-domain is {3, 0, - 1, 0, 3}.
We know range ⊆ codomain.
Therefore, The range is {- 1, 0, 3}.
