How many solutions does the equation 5x+17=4(3x−1) have?
Stella [2.4K]

<u>Answer:</u>

one solution = 3

<u>Step-by-step explanation:</u>

Let's solve your equation step-by-step.

5x+17=4(3x−1)

Step 1: Simplify both sides of the equation.

5x+17=4(3x−1)

5x+17=(4)(3x)+(4)(−1)(Distribute)

5x+17=12x+−4

5x+17=12x−4

Step 2: Subtract 12x from both sides.

5x+17−12x=12x−4−12x

−7x+17=−4

Step 3: Subtract 17 from both sides.

−7x+17−17=−4−17

−7x=−21

Step 4: Divide both sides by -7

-7x/-7 = -21/-7 = 3

Find an equation of the plane through the point (−1,−5,−2)(−1,−5,−2) with normal vector n=⟨−5,−4,−1⟩n=⟨−5,−4,−1⟩.
Ostrovityanka [42]
Consider this option:
1. given: n(A;B;C)=n(-5;-4;-1) and A(-1;-5;-2)=A(x₀;y₀;z₀).
Common view of equation for a plane is Ax+By+Cz+D=0, where A,B,C,D - numbers.
2. from another side using coordinates of A and normal vector it is possible to make up the equation: A(x-x₀)+B(y-y₀)+C(z-z₀)=0 ⇒ -5(x+1)-4(y+5)-(z+2)=0; ⇒ -5x-4y-z-27=0 or 5x+4y+z+27=0.

G(r)=−(r+11)(r+14)
Oduvanchick [21]

Answer:

The zeros are

Larger r=-11

Smaller r=-14

2)The vertex is (-12.5,-2.25)

Step-by-step explanation:

The given function is:

g(r)=(r+11)(r+14)

This function is already in the factored form therefore it is easy to find the zeros,

(r+11)(r+14)=0

Either (r+11)=0 or (r+14)=0

The zeros are r=-14 or r=-11

b) The expanded form of the given function is:

g(r)=r^2+25r+154

We obtain the vertex form by completing the square:

g(r)=r^2+25r+(\frac{25}{2})^2+154-(\frac{25}{2})^2

The vertex form is:

g(r)=(r+\frac{25}{2})^2-(\frac{9}{4}

Therefore the vertex is (-12.5,-2.25)
