x=2y-6;y=3x-7
substitution to solve systems of equations
As you said, we can solve this system for y by using substitution.
[tex]x = 2y - 6\\y = 3x - 7\\\\y = 3(2y - 6) - 7\\\\y = 6y - 18 - 7\\\\y = 6y - 25\\\\-5y = -25\\\\y = 5[/tex]
Now, using what we got for y, we plug it into one of the original equations to solve for x.
[tex]x = 2(5) - 6\\\\x = 10 - 6\\\\x = 4[/tex]
Now we have the solution of this system.

For the given equations x=2y-6 and y=3x-7 the value of x is 4 and the value of y is 5.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two equations are x=2y-6 and y=3x-7. The value of x and y will be calculated as,
x=2y-6
y=3x-7
Solve the above equations by substitution method,
x=2(3x-7)-6
x = 6x -14 - 6
6x - x = 20
5x = 20
x = 4
The value of y will be calculated as,
y=3x-7
y = ( 3 x 4) - 7
y = 12 - 7
y = 5

For 0° ≤ x < 360°, what are the solutions to sin(StartFraction x Over 2 EndFraction) + cos(x) – 1 = 0 ?
{30°, 150°}
{60°, 300°}
{120°, 240°}
{210°, 330°}
{60°, 300°}
Using the half angle identity:
[tex]\sin\left(\frac{x}{2}\right)+\cos\left(x\right)-1=0\\\sin\left(\frac{x}{2}\right)+1-2\sin^{2}\left(\frac{x}{2}\right)-1=0\\\sin\left(\frac{x}{2}\right)-2\sin^{2}\left(\frac{x}{2}\right)=0\\\sin\left(\frac{x}{2}\right)\left(1-2\sin\left(\frac{x}{2}\right)\right)=0\\[/tex]
Using zero product rule:
[tex]\sin\left(\frac{x}{2}\right)=0,\frac{1}{2}\\x=\frac{x}{2}=0,30,150,180\\x=0,60,300,360[/tex]
Since, 0° ≤ x < 360°, so, x=60,300

Answer:
m∠XYZ = 162°
Step-by-step explanation:
We can see that ∠XYZ is an exterior angle while ∠W and ∠X are the opposite interior angles.
We know that the exterior angle of triangle is equal to the sum of opposite interior angles
Given
m∠XYZ = (15x-18)°
m∠W = (5x+2)°
m∠X = (8x+4)°
Mathematically it can be written as:
m∠X+m∠W = m∠XYZ
[tex]8x+4+5x+2 = 15x-18\\13x+6 = 15x-18\\13x-15x = -18-6\\-2x = -24\\\frac{-2x}{-2} = \frac{-24}{-2}\\x = 12[/tex]
Putting x=12 in m∠XYZ
[tex]15x-18\\=15(12)-18\\=180-18=162[/tex]
Hence,
m∠XYZ = 162°
The perimeter of a rectangle is 42 inches inches if the width of the rectangle is 6 inches what is the length
Answer:
15 I think.
Step-by-step explanation:
If the perimeter is 42 inches and the width is 6 inches. That is only one side so you multiply.6 by 2 to get 12. Then 42 minus 12 is 30. Finally you split 30 into 2, to get the length. Since there are to sides. So 15.
