These tiles represent the expression 2(5x–3)–9x. Which expression is equivalent to 2(5x–3)–9x?

Answer:

6±√10

Step-by-step explanation:

x^2-12x+26=0

x= ± √10  +6

6±√10

The solutions of the given quadratic equation  [tex]x^2 - 12x + 26 = 0[/tex] are;

x = 6 + √10 and x = 6 - √10.

To solve the quadratic equation [tex]x^2 - 12x + 26 = 0[/tex]

using completing the square method, follow the steps below.

Move the constant term to the right side of the equation

[tex]x^2 - 12x = -26[/tex]

To find the value that completes the square, divide the coefficient of x by 2 and square it.

[tex](-12/2)^2 = 36[/tex]

Add and subtract the value obtained in step 2 to the left side of the equation

[tex]x^2 - 12x + 36 - 36 = -26[/tex]

Simplify the left side of the equation by factoring the perfect square trinomial

[tex](x - 6)^2 - 36 = -26[/tex]

Add 36 to both sides of the equation to isolate the perfect square trinomial

[tex](x - 6)^2 = 10[/tex]

To Take the square root of both sides of the equation

x - 6 = ±√10

Solve for x

x = 6 ± √10

So, the solutions of the given quadratic equation  [tex]x^2 - 12x + 26 = 0[/tex] are x = 6 + √10 and x = 6 - √10.

Answer:

No because of the 3xy term. For an equation to be considered linear there has to be one y value for every x value given

The answer is 3xy + 8 = 4y  is not a linear equation.

Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.

Given here: 3xy + 8 = 4y

The degree of this equation is 2 and thus the graph of this equation is not linear.

Hence, 3xy + 8 = 4y  is not a linear equation

Answer:

150

Step-by-step explanation:

its 150 without taxes

Answer:

350

Step-by-step explanation:

Assumung that the $500 is before taxes, Jamel would have to pay $350.

$500 = price before discount

30% = discount

This means that Jamel would be paying 70% of the orginal price, because 30% of it is already taken off.

0.7*500=350

Answer: $350

Answer:

y-1 = 5(x+8)

Step-by-step explanation:

The standard equation of a line in point slope form is expressed as;

y-y0 = m(x-x0)

m is the slope

(x0, y0) is the point

Given

Slope m = 5 (assumed value)

Point (-8,1)

Substitute the given data's into the formula

y -1 = 5(x-(-8))

y-1 = 5(x+8)

Hence the required equation is y-1 = 5(x+8)

Answer:

(8, -22)

Step-by-step explanation:

If you solve to find the slope of the first table on the left you get -4x +10 and the second table you get -3x+2. You can find their intersection on the calculator and get (8, -22)

Answer:

A.) This system has no solutions.

Step-by-step explanation:

y = 1/2x + 4

-1/2x + y = -5

-1/2x + (1/2x + 4) = -5

4 = -5

The system has no solutions, if we graph it, we get that it has the same slope with two different y-intercepts, these two are parallel. These two points will never meet at a point.

Answer:

use the relationship between coefficients of a pair of linear equations for no solutions i.e. a1/a2 equal to b1/b2 not equal to c1/c2 .

Here, a is coefficient of x and b is coefficient of y and c is constant term in both equation but make sure that you put the values of a1,a2,b1,b2,c1 and c2 after converting both equation in the form ax+by+c=0 with proper sign and here y=1/2(x) +4 is equation 1 and other is equation 2

Answer:

I haven't learned this but I think it's D.

Step-by-step explanation:

Answer:  

X + Y = 5.678

X - Y = 9.876

The two numbers: X = 7.777   Y = -2.099

Step-by-step explanation: solve by elimination

X + Y = 5.678

X - Y = 9.876 . Add the two equations so the y cancels. Solve for x

2x = 15.554 .  Divide both sides by 2

X = 7.777    Substitute in the original equations to find Y

7.777 + y = 5.678 . Subtract 7.777 from both sides

Y = - 2.099

check in the second equation:

7.777 -(-2.099) = 9.876

7.777 + 2.099 = 9.876 True

The two numbers is X = 7.777 and Y = -2.099.

And, the two equation is X + Y = 5.678  and X - Y = 9.876.

Given that,

Based on the above information, the calculation is as follows:

X + Y = 5.678

X - Y = 9.876

2x = 15.554  

X = 7.777    

Now  

7.777 + Y = 5.678  

Y = - 2.099

Therefore, the above should be the answers.
