What is 2+x/5+x=7/8?

Answers

Answer 1
Answer:

Answer:

x = - (15)/(16)

Step-by-step explanation:

2 + (x)/(5) + x = (7)/(8)

Multiply through by 40 ( the LCM of 5 and 8 ) to clear the fractions

80 + 8x + 40x = 35

48x + 80 = 35 ( subtract 80 from both sides )

48x = - 45 ( divide both sides by 48 )

x = - (45)/(48) = - (15)/(16)

Which is a third degree polynomial with -3 and 2 as its only zeros?a. f(x)=x^3+x^2-8x-12
b. f(x)=x^3+2x^2-5x-6
c. f(x)=x^3+4x^2-3x-18
d. f(x)=x^2+x-6

Answers

Answer:b

Step-by-step explanation:

f(x)=x^3+2x^2-5x-6

Put x= -3 in the equation

f(-3)=-3^3+2*3^2-5*3-6

= -27+18+15-6= 0

f(2)= 2^3+2*2^2-5*2-6

=8+8-10-6= 0

Given a polynomial f(x), if (x - 2) is a factor, what else must be true?f(2) = 0

f(-2) = 0

f(0) = 2

f(0) = -2

Answers

If a number is a root of a polynomial, then we substitute the number to x of the polynomial, the answer or y is equal to zero. Hence, in this situation, if (x - 2) is a factor, the root is equal to 2. This means then that upon substituting 2 to the function, y is equal to zero. Answer then is A. f(2) = 0

One side of a triangular garden is x feet long. The other two sides of the garden are both 5 feet less than twice the length of the first side of the garden.Part A: Write a simpiflied expression for perimeter, in feet, of the garden.

A fence is placed along the entire perimeter of the triangular garden. The roll of fencing is 40 ft long.

Part B: Write a simplified expression to show the amount of fencing, in feet, which is left from the roll of fencing.

Answers

I think Part A is (X x 2)-5 and Part B is 40 x 3. I'm not so sure because I'm in 5th grade and I haven't learned this yet. I hope it helps a little bit and I hope it is right.

What value of k satifies the equation 7(7 - k) +3k = -2(9k + 4) + 15

Answers

To find the value of k that satisfies the equation 7(7 - k) + 3k = -2(9k + 4) + 15, you can follow these steps:

1. Distribute the constants and variables on both sides of the equation:

7 * 7 - 7 * k + 3k = -2 * 9k - 2 * 4 + 15

2. Simplify both sides:

49 - 7k + 3k = -18k - 8 + 15

3. Combine like terms on each side:

(49 - 8) - 4k = -18k + 15

41 - 4k = -18k + 15

4. Move the variable terms to one side and the constant terms to the other side by adding 18k and subtracting 41 from both sides:

41 - 4k + 18k = 15

14k - 41 = 15

5. Add 41 to both sides to isolate the variable term:

14k = 15 + 41

14k = 56

6. Finally, divide by 14 to solve for k:

k = 56 / 14

k = 4

So, the value of k that satisfies the equation is k = 4.
