Solve for x in equation x-c/2=d

1 answer:

4 0

X-c/2 = d
Multiply by 2 on both sides. Leaves us with:
x-c = 2d
Add 2 to both sides. Leaves us with:
x = 2d + c
Unless you have values to substitute into the variables, this is your answer:
x = 2d + c

Jenna has already written 35 pages, and she expects to write 1 page for every additional hour spent writing. How many hours will

Julli [10]

Answer:

15 hours

Step-by-step explanation:

When reading the context it gives you two important numbers; the first one being (35).

Next important number is that she is going to spend (1) hour for each additional page she writes.

Third important number is that she needs a total of (50) pages.

Now lets arrange the numbers in an order we can find the solution to the problem at hand.

take 50-35=15. For her to have a total of 50 pages Jenna will need to write 15 more pages, if Jenna writes 15 more pages and each page takes an hour she will spend 15 hours total.

A cone shaped vase has a radius of 12 cm and a height of 45 cm. What is the exact value of the volume of the cone?

likoan [24]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=12\\ h=45 \end{cases}\implies V=\cfrac{\pi (12)^2(45)}{3}\implies V=2160\pi$

if the zeros of a quadratic formula function F are -2 and 4 what is the equation of the axis of symmetry F?

Vera_Pavlovna [14]

Option 2 is correct.

The axis of symmetry is, x= 3

Step-by-step explanation:

Given: The zeros of the quadratic function f are 1 and 5.

If the zeroes are at x =1 and at x =5, then,

the factor equations were x- 1=0 and x-5 = 0.

Then. the factors were x -1 and x-5 .

Any factorable quadratic is going to have just the two factors, so these are must be them.

Then, the original quadratic was :

[by distributive property ]

Combine like terms;

......[1]

A quadratic equation is of the form: ; where a, b, c are the coefficient ]

On comparing equation [1] with general equation we have;

the value of a = 1 , b = -6 and c =5

Axis of symmetry states that a parabola is a vertical line that divides the parabola into two congruent halves.

i,e

Then;

Axis of symmetry (x) =

Therefore, the equation of the axis of symmetry is; x = 3
