Answer:

If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.

Step-by-step explanation:

Answer:

1) no, because a solution must be an ordered triple pair (x,y,z)

2) { x+y+z=5    

   { 2x-3y+z=7      

   { x+2y-4z=2

3) infinity many solutions

4) use equations (1) and (2) to eliminate y

5) solve one equation for one of its variables

Answer:

(2,-17) should be the minimum.

Step-by-step explanation:

The minimum of a quadratic function occurs at [tex]x=-\frac{b}{2a}[/tex] . If a is positive, the minimum value of the function is [tex]f(-\frac{b}{2a})[/tex]

[tex]f_{min}x=ax^2+bx+c[/tex] occurs at [tex]x=-\frac{b}{2a}[/tex]

Find the value of [tex]x=-\frac{b}{2a}[/tex]

x = 2

evaluate f(2).

replace the variable x with 2 in the expression.

[tex]f(2)=5(2)^2-20(2)+3[/tex]

simplify the result.

[tex]f(2)=5(4)-20(2)+3[/tex]

[tex]f(2)=20-40+3[/tex]

[tex]f(2)=-17[/tex]

The final answer is -17

Use the x and y values to find where the minimum occurs.

Answer:

1.3(x + 2) = 12

2.3x + 6 = 12

Answer:no

Step-by-step explanation:

Step-by-step explanation:

-2y = 6x + 6

y = -3x - 3.

Since (1/3)(-3) = -1, the 2 lines are perpendicular to each other

Answer:

B

Step-by-step explanation:

When you simplify the second equation

-2y = 6x + 6

you divide both sides by -2

y = -3x - 3

notice equation 1's slope is 1/3 and equation 2's slope is -3, for the second, it is negative and a reciprocal of the first, that suggests they are perpendicular to one another.

Answer:

3/5

Step-by-step explanation:

From the above question,

Fraction of used coupons = 2/5

Let us assume the total number of coupons sent = 1

The Fraction of unused coupons =

1 - 2/5

= 3/5

Therefore, the fraction of unused coupons = 3/5

Answer:

Let's factor x2+3x−18

x2+3x−18

The middle number is 3 and the last number is -18.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 3

Multiply together to get -18

Can you think of the two numbers?

Try -3 and 6:

-3+6 = 3

-3*6 = -18

Fill in the blanks in

(x+_)(x+_)

with -3 and 6 to get...

(x-3)(x+6)

Answer:

(x−3)(x+6)

Step-by-step explanation:

The solution to the equation (x - 3)² + 2(x - 3) - 8 = 0 is,

B) x= - 1 and x = 5.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

Given, A quadratic equation of the form (x - 3)² + 2(x - 3) - 8 = 0.

Substituting, U = (x - 3).

(U)² + 2(U) - 8 = 0.

U² + 4U - 2U - 8 = 0.

U(U + 4) - 2(U + 4) = 0.

(U + 4)(U - 2) = 0.

U = - 4, 2.

x - 3 = - 4, 2.

x = - 4 + 3, 2 + 3.

x = - 1, 5.

So, The solution to the equation is - 1, 5.

Answer:

a= 12

Step-by-step explanation:

Use pythagorean theorem

a^2 + b^2 = c^2 where c is the hypotenuse

so 9^2 + a^2 = 15^2

81 + a^2 = 225

a^2 = 144

square root both sides to get a = 12

Hi there.

The answer is (x-2y-8)(x-2y-4)

Explanation:

[tex](x - 2y)^{2} - 12(x - 2y) + 32[/tex]

Let (x-2y) = x

[tex] {x}^{2} - 12x + 32[/tex]

Then factor the quadratic polynomial by 2 brackets factoring.

[tex](x - 8)(x - 4)[/tex]

Then convert x to (x-2y)

[tex](x - 2y - 8)(x - 2y - 4)[/tex]

Answer:

122

Step-by-step explanation:

11x-65+58=180. The 58 comes from adding 29+29=58. You do this because there are two 29 due to it being an isosceles triangle meaning there are two sides equal.

Add your a like terms

11x-7=180

11x=180+7

11x=187

x=17

Plug the 17 in for 11x-65

11*17-65=122

You can change yourself by adding 29+29+122=180. You know this right because all triangles add to 180. '

That might be the answer sorry if im wrong

Answer:

Please check the explanation

Step-by-step explanation:

Given the function

[tex]f\left(x\right)\:=\:\left(x-5\right)^3-1[/tex]

Given that the output = -3

i.e. y = -3

now substituting the value y=-3 and solve for x to determine the input 'x'

[tex]\:\:y=\:\left(x-5\right)^3-1[/tex]

[tex]-3\:=\:\left(x-5\right)^3-1\:\:\:[/tex]

switch sides

[tex]\left(x-5\right)^3-1=-3[/tex]

Add 1 to both sides

[tex]\left(x-5\right)^3-1+1=-3+1[/tex]

[tex]\left(x-5\right)^3=-2[/tex]

[tex]\mathrm{For\:}g^3\left(x\right)=f\left(a\right)\mathrm{\:the\:solutions\:are\:}g\left(x\right)=\sqrt[3]{f\left(a\right)},\:\sqrt[3]{f\left(a\right)}\frac{-1-\sqrt{3}i}{2},\:\sqrt[3]{f\left(a\right)}\frac{-1+\sqrt{3}i}{2}[/tex]

Thus, the input values are:

[tex]x=-\sqrt[3]{2}+5,\:x=\frac{\sqrt[3]{2}\left(1+5\cdot \:2^{\frac{2}{3}}\right)}{2}-i\frac{\sqrt[3]{2}\sqrt{3}}{2},\:x=\frac{\sqrt[3]{2}\left(1+5\cdot \:2^{\frac{2}{3}}\right)}{2}+i\frac{\sqrt[3]{2}\sqrt{3}}{2}[/tex]

And the real input is:

[tex]x=-\sqrt[3]{2}+5[/tex]
