Answer:

It is not a function.

Step-by-step explanation:

This is what we call a mapping;

Functions do not give multiple output values for a given input value;

As we can see, the input 2 produces an output of 20 and 40, therefore we can tell this is not a function.

Solve. -1/8c=2 a. 4 b. –16 c. –4 d. 16

kotykmax [81]

$\frac{-1}{8c} =2$
This requires that c ≠ 0 , meaning c≠0
$\frac{-1}{8c} =2$
Multiply by x to eliminate var in denominator
$\frac{ \not c*(-1)}{ 8 \not c} =c*2$
$\frac{-1}{8} =c*2$
Common denominator is 8
$\frac{\not 8(-1)}{\not 8} =8c*2$
$-1=8c*2$
$-1=16c$
$x=-16$
The answer is: b. -16

Need help answering this

torisob [31]

Hello,

The equation is written in point-slope form, and the formula is as follows: $y-y_{1} = m(x - x_{1})$ .

$x_{1}$ and $y_{1}$ are representing points on the graph.
$y_{1} = 5$ , and $x_{1} = 7$ .

So therefore, the final answer is B, (7, 5).

Solve the equation 2x^{2}-12x-14=x^{2}-8x2x 2 −12x−14=x 2 −8x to the nearest tenth

dlinn [17]

Answer:

x = 6.2 or -2.2

Step-by-step explanation:

Given:

2x² - 12x - 14 = x² - 8x

Collect like terms

2x² - x² - 12x + 8x - 14 = 0

x² - 4x - 14 = 0

a = 1

b = -4

c = -14

x = -b ± √b² - 4ac / 2a

= -(-4) ± √(-4)² - 4(1)(-14) / 2(1)

= 4 ± √16 -(-56) / 2

= 4 ± √16 + 56 / 2

= 4 ± √72 / 2

= 4 ± 6√2 /2

= 4/2 + 6√2/2 or 4/2 - 6√2/2

= 2 + 3√2 or 2 - 3√2

= 2 + 4.2426406871192 or 2 - 4.2426406871192

= 6.2426406871192 or -2.2426406871192

Approximately,

x = 6.2 or -2.2
