The following equation defines f(x)=-3x-5 . If (-5,n) is an ordered pair of the function rule, what is the value of n?
ElenaW [278]

Given:

The function is

f(x)=-3x-5

(-5,n) is an ordered pair of the function rule.

To find:

The value of n.

Solution:

If (-5,n) is an ordered pair of the function rule, then the function must be satisfied by the point (-5,n). It means f(-5)=n.

Substitute x=-5 in the given function.

f(-5)=-3(-5)-5

f(-5)=15-5

f(-5)=10

We know that, f(-5)=n. So,

n=10

Therefore, the value of n is 10.

Rewrite as a cube: 64; −216; 0.008; 1/64; 4 17/27
alukav5142 [94]

64 = 4³

-216 = (-6)³

.008 = 0.2³ . . . . . . 1000 = 10³, 8 = 2³. This is 8/1000, so the cube of 2/10

1/64 = (1/4)³ . . . . . . the inverse of the first number

4 17/27 = 125/27 = (5/3)³

_____

You can see that it would be helpful to have memorized the cubes of small integers.

BartSMP [9]

Answer:

Step-by-step explanation:

x_{1,\:2}=\frac{-\left(-29\right)\pm \sqrt{\left(-29\right)^2-4\cdot \:14\left(-15\right)}}{2\cdot \:14}     so    x=\frac{5}{2}     x=-\frac{3}{7}
