F is the variable. since f is equal to 6.1 you can plug it into the other equation. you multiply 2 and 6.1. this equals 12.2 then you add two. the final answer is 14.2

Plug in 6.1. It replaces f. Now multiply 2 times 6.1. That's 12.2. Now add 5. That's 17.2

There are 2 questions in one.

1)

<u>Roberta is 20 years older than Julian. In 4 years, Roberta's age will be twice Julian's age:</u>

  • r = j + 20
  • r + 4 = 2j

---------------------------

2)

<u>Roberta is twice as old as David. In 10 years, Roberta will be 8 less than three times David's present age:</u>

  • r = 2d
  • r + 10 = 3d - 8

Answer:

c^2 +17c -5

Step-by-step explanation:

I like to line them up vertically

2c^2 +7c - 1

- (c^2 -10c+4)

----------------------

Distribute the minus sign

2c^2 +7c - 1

- c^2 +10c-4

----------------------

c^2 +17c -5

G(1)=2.7 <br> g(n)=g(n-1)*6.1 <br> find an explicit formula for g(n)
Ksju [112]

By substitution,

g(2)=6.1g(1)

g(3)=6.1g(2)=6.1^2g(1)

g(4)=6.1g(3)=6.1^3g(1)

and so on, so that

[tex]g(n)=6.1^{n-1}g(1)=2.7\cdot6.1^{n-1}

Which is the equation of a parabola with vertex (0, 0), that opens to the left and has a focal width of 12?
sattari [20]

Answer:

\text{Equation of parabola is }y^2=-12x

Step-by-step explanation:

We need to find the equation of parabola using given information

  • Vertex: (0,0)
  • Open to the left
  • Focal width = 12

If parabola open left and passes through origin then equation is

y^2=-4ax

Focal width = 12

Focal width passes through focus and focus is mid point of focal width.

Focus of above parabola would be (-a,0)

Passing point on parabola (-a,6) and (-a,-6)

Now we put passing point into equation and solve for a

6^2=-4a(-a)

a=\pm 3

a can't be negative.

Therefore, a=3

Focus: (-3,0)

Equation of parabola:

y^2=-12x

Please see the attachment of parabola.

\text{Thus, Equation of parabola is }y^2=-12x
