-6 + 7 = 1 and -6*7 = -42

So f(x) = (x + 7)(x - 6)

sergejj [24]

Answer:

X = 15

Step-by-step explanation:

We move all terms to the left:

x+8+2x-(2x+13)=0

We add all the numbers together, and all the variables:

3x-(2x+13)+8=0

We get rid of parentheses:

3x-2x-13+8=0

We add all the numbers together, and all the variables:

x-5=0

We move all terms containing x to the left, all other terms to the right:

x=5

If John is driving 70 mi/hr and Jim is driving 50 ft/min, who is driving faster?

lapo4ka [179]

Answer:

John

Step-by-step explanation:

70 mi/(60 min) ≈ 1 1/6 mi/min.

1 1/6 miles is significantly farther than 50 ft, so John is driving (much) faster.

Determine the values of k and p so that the solution is "All Reals" when solving for y:

Angelina_Jolie [31]

Answer:

The value of k is $\pm 9$ and The value of p is - 23

Step-by-step explanation:

Given equation as :

81 y - 17 = k² y + 6 + p

The equation has real solution ,

Now for real solution the equation have no solution

∵ The equation has no solution the ,

The coefficient of y must be equal

I.e 81 = k²

Or, k = $\sqrt{81}$

∴ k = $\pm 9$

Again , If the coefficient of y is same then the equation is written as

6 + p = - 17

or, p = - 17 - 6

or, p = - 23

Hence The value of k is $\pm 9$ and The value of p is - 23 Answer
