Bring all the equation from the right side to the left.
2x² - 2 = - 5x - 1
2x² + 5x - 2 + 1 = 0 (take note that as you bring the number over you also have to flip the sign)
Therefore,
2x² + 5x + 1 = 0 (shown)
( this ans is similar to the form of ax² + bx + c = 0 )
The equation below written in the form ax² + bx +c= 0 is 2x² + 5x + 1 = 0
What is Quadratic equation?In algebra, a quadratic equation is any equation that can be rearranged in standard form as where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no ax² term.
Examples of quadratic equations are: 6x² + 11x – 35 = 0, 2x² – 4x – 2 = 0, 2x² – 64 = 0, x² – 16 = 0, x² – 7x = 0, 2x² + 8x = 0 etc.
given:
2x² - 2 = - 5x - 1
2x² + 5x + 1 = 0.
Here, the above equation is in standard form as ax² + bx +c= 0.

Step-by-step explanation:
Hannah has 3 places to hang pictures on her wall.she has 6 possible pictures all together. How many possible arrangements of pictures can she hang?
The number of possible arrangements of pictures she can hang on her wall is 120.
How many possible arrangements of pictures can she hang?
The number of possible arrangements can be determined by dividing the factorial of 6 by the factorial of 3.
Number of possible arrangements = 6! / 3!
( 6 x 5 x 4 x 3 x 2 x 1) / (3 x 2 x 1) = 6 x 5 x 4 = 120

Given the graph, find the distance of GH. Round to the nearest tenth.
Answer:
GH = 6.3 units
Step-by-step explanation:
Assuming that 1 box represents 1 unit, the coordinate pair of G = (-2, -3), while H = (0, 3).
Distance between G and H = [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] G(-2, -3) = (x_1, y_1) [/tex]
[tex] H(0, 3) = (x_2, y_2) [/tex]
[tex] GH = \sqrt{(0 - (-2))^2 + (3 - (-3))^2} [/tex]
[tex] GH = \sqrt{(2)^2 + (6)^2} [/tex]
[tex] GH = \sqrt{4 + 36} = \sqrt{40} [/tex]
[tex] GH = 6.3 units [/tex] (nearest tenth)
11(15g-13)=-6 help please
Answer:
g = 0.83
Step-by-step explanation:
11(15g-13) =-6
165g - 143 = -6
165g = 137
165 165
g = 0.83
The solution of the given equation 11(15g-13) = -6 is g = 0.83
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
11(15g-13) = -6
To solve the above equation following steps are taken,
Divide both the side of the equation by 11
11(15g-13)/11 = -6/11
Solving them we get,
15g - 13 = -6/11
Adding 13 both the sides,
15g - 13 + 13 = -6/11 + 13
So we obtain,
15g = -6/11 + 13
Solving the numbers right hand side,we get
15g = 137/11
Dividing both the sides by 15 we get,
g = 137/165
or, g = 0.83
Hence,The solution of the given equation 11(15g-13) = -6 is g = 0.83

Find the general solution of the following equation: y'(t) = 3y -5
Answer:
The general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
Step-by-step explanation:
Since the differential equation is given as y'(t) = 3y -5
The differential equation is re-written as
dy/dt = 3y - 5
separating the variables, we have
dy/(3y - 5) = dt
dy/(3y - 5) = dt
integrating both sides, we have
∫dy/(3y - 5) = ∫dt
∫3dy/[3(3y - 5)] = ∫dt
(1/3)∫3dy/(3y - 5) = ∫dt
(1/3)㏑(3y - 5) = t + C
㏑(3y - 5) = 3t + 3C
taking exponents of both sides, we have
exp[㏑(3y - 5)] = exp(3t + 3C)
3y - 5 = [tex]e^{3t}e^{3C}[/tex]
3y - 5 = [tex]Ae^{3t}[/tex] [tex]A = e^{3C}[/tex]
3y = [tex]Ae^{3t}[/tex] + 5
dividing through by 3, we have
y = [tex]\frac{A}{3}e^{3t}[/tex] + 5
So, the general solution of the equation is y = [tex]\frac{A}{3}e^{3t}[/tex] + 5

What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
Your car can drive 300 miles on a tank of 15 gallons
300 miles → 15 gallons
Let x be the number of miles or distance a car travel in 40 gallons
x → 40 gallons
300/x = 15/40
x = (300×40)/15
x = 800 miles
Thus, the car travels 800 miles in 40 gallons if the car can drive 300 miles on a tank of 15 gallons.

Write an equation in slope-intercept form for the line described. Slope 9/2, passes through (0,-13/2)
Use slope-intercept equation form: [tex]y=mx+b[/tex]
We know that the slope is 9/2
[tex]y=\frac{9}{2}[/tex]
[tex]y=\frac{9}{2}x+b[/tex]
To solve for b, we can plug in the point given, since it's on the line.
[tex]-\frac{13}{2}=\frac{9}{2}(0)+b[/tex]
[tex]b=-\frac{13}{2}[/tex]
