You can use substitution or elimination or graphing to solve the equation. Since both of the equations are in slope intercept form it will be easier to use substitution or to graph it and find the point of interception.

You can write (6x=10)=(-4x-20), because both expressions are equal to the same thing, so they're equal to each other. From that, you easily solve for 'x', and then write that number back into one of the original equations to find 'y' .

Answer:

(2,-7)

Step-by-step explanation:

Plug in the numbers to test and see if it gives you -17 and -8.

Option 1. 2(-4)+3(2)

= -8+6 = -2. Not it.

Option 2. 2(2)+3(-7)

4 - 21 = -17 Works. Try the second equation to make sure.

3(2)+2(-7)

6-14 = -8. Works.

(2,-7) is the answer.

In point b:

¬∀x∃yP (x, y)

∃x∀y ¬P(x,y)

In point c:

In point d:

¬∃y(∃xR(x, y) ∨ ∀xS(x, y))

∀y(∀x>R(x,y)) $\wedge$ ∃x>s(x,y))

In point e:

Write the given differential equation in the form L(y) = g(x), where L is a linear differential operator with constant coefficie

Greeley [361]

Answer:

The differential equation will be like the one shown below

Step-by-step explanation:

Data:

Let the equation be given as:

y(4) + 8y' = 6

The equation will be expressed linearly as follows:

y(4) + 8 $\frac{dy}{dx} = 6$

$8\frac{dy}{dx}+ 4y = 6$

This is the linear form of the differential equation.

If a(x)=2x-4 and b(x) =x+2, which of the following expressions produces a quadratic function?

ZanzabumX [31]

Answer:

$(ab)(x)$

Step-by-step explanation:

The complete question in the attached figure

we have

$a(x)=2x-4\\b(x)=x+2$

we know that

(ab)(x) is equal to the product of a(x) and b(x)

so

$(ab)(x)=(2x-4)(x+2)$

Applying distributive property

$(ab)(x)=2x(x)+2x(2)-4(x)-4(2)$

$(ab)(x)=2x^2+4x-4x-8$

$(ab)(x)=2x^2-8$

This is a quadratic equation

The other expressions not produce a quadratic equation
