Y=2x-1 Graph the equation? (steps please thanks!)

Answers

Answer 1

Answer: $y=2x-1\n\ny-intercept\ (x=0)\n\ny=2\cdot0-1=-1\to(0;-1)\n\nx-intercept\ (y=0)\n\n2x-1=0\n2x=1\nx=0.5\to(0.5;\ 0)$

Answer 2

Answer: There are many ways to graph this equation.
Here's one that you should be able to manage:

-- Pick any number at all for 'x'.
[ y = 2x - 1 ], so double your number and subtract 1 to find 'y'.
Mark a point on your graph at (x, y) .

-- Pick any different number at all for 'x'.
[ y = 2x - 1 ], so double your number and subtract 1 to find 'y'.
Mark a point on your graph at (x, y) .

-- Using your pencil and ruler, connect the two points that you have marked
on your graph. Without moving the ruler, you may extend the line as far as you
want in each direction.

What is quadratic equation?

" Quadratic equation is defined as the polynomial whose highest degree of the given variable is equals to 2."

According to the question,

Given equations,

$x-2y=3$

⇒ $x=3 + 2y$ ____(1)

Quadratic equation,

$3x^(2) -5xy-16y=24$ ____(2)

Substitute the value of 'x' from (1) in (2) quadratic equation we get,

$3(3+2y)^(2) -5(3+2y)y-16y=24$

⇒ $3(9+12y+4y^(2) )-5y(3+2y) -16y-24=0$

⇒ $27+36y+12y^(2) -15y-10y^(2) -16y-24=0$

⇒ $2y^(2) +5y+3=0$

⇒ $2y^(2) +2y+3y+3=0$

⇒ $2y(y+1)+3(y+1)=0$

⇒ $(2y+3)(y+1)=0$

⇒ $(2y+3)=0 or (y+1)=0$

⇒ $y=(-3)/(2) or y = -1$

Substitute in (1) to get the value of 'x' ,

$x= 3+ 2((-3)/(2)) or x = 3 + 2 (-1)$

⇒ $x = 0 or x = 1$

Hence, value of x = 0 or 1 and value of y = $(-3)/(2)$ or -1 for the given quadratic equation.

x-2y=3 ⇒y=(x-3)/2
3x²-5xy-16y=24

We can suggest this system of equations by substitution method.
y=(x-3)/2

3x²-5x(x-3)/2-16(x-3)/2=24
least common multiple=2
6x²-5x(x-3)-16(x-3)=48
6x²-5x²+15x-16x+48=48
x²-x=0
x(x-1)=0
Now, we solve two equations:
1)x=0 ⇒y=(0-3)/2=-3/2
2)x-1=0
x=1 ⇒y=(1-3)/2=-1

Answer: we can two solutions:
solution1: x=0; y=-3/2
solution2: x=1, y=-1

The best strategy when shopping for life insurance is option (c): Figure out how much coverage you need, then comparison shop using the Web and other resources.

Choosing life insurance is an important decision that impacts your loved ones' financial security in the future. Rather than solely relying on an agent's recommendations or employer-provided coverage, it's crucial to assess your specific needs and financial situation. Take the time to determine the appropriate amount of coverage based on factors like family expenses, outstanding debts, and future financial goals.

Once you have a clear understanding of your needs, comparison shopping allows you to explore various insurance providers, their policy features, and premiums. This enables you to find the best policy that meets your requirements and provides value for your money. Making an informed decision ensures you have the right life insurance coverage to protect your loved ones in the long run.

A rectangular room is four times as long as it is wide, and its perimeter is 70 meters. Find the width of the room.

Answers

W=3/4L
P=2L=2W
70=2L+2(3/4L)
70=2L+6L/4
70=2L+1.5L
70=3.5L
L=70/3.5
L=20 FT. ANS. FOR THE LENGTH.
W=4/4*20=15 ANS. FOR THE WIDTH

i think.

2(4w) + 2w = 70
8w + 2w = 70
10w = 70
W= 7 m

Again, you just have to learn to make the equations. :)

(Help me) been try to solve for three days! !!!!!!!!!!!!!! does anybody knows this answer !!!!! please !!!!! -Circles very difficult for me thank you !!!

Answers

Given:
diameter = 12 ft

Area = π r²

r = radius. It is 1/2 of the diameter.
r = 12 ft / 2 = 6 ft.

Area = 3.14 * (6ft)²
A = 3.14 * 36ft²
A = 113.04 ft² or 113.0 ft² rounded to the nearest tenth.
