The table shows ordered pairs of the function . What is the value of y when ?

LiRa [457]

Answer:

(B) -8

Step-by-step explanation:

Given the 2-column table below:

$\left|\begin{array}{c|c}x&y\\--&--\\-3&14\\-1&10\\1&6\\4&0\\8&?\\10&-12\end{array}\right|$

Taking the pair (-3,14) and (-1,10)

$Slope, m=\dfrac{10-14}{-1-(-3)} =\dfrac{-4}{2} =-2$

Taking the pair (1,6) and (4,0)

Slope, $m=\dfrac{0-6}{4-1} =\dfrac{-6}{3} =-2$

Since the slope is constant, the table represents a linear function whose slope is -2. Therefore:

Taking the pair (8,y) and (4,0)

Slope, $m=\dfrac{0-y}{4-8} =-2$

$\dfrac{-y}{-4} =-2\\y=-2*4=-8$

Therefore, the value of ? on the y-column is -8.

Monica [59]

Answer: k = 27

Step-by-step explanation:

Here's the complete question:

Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.

An increase in k simply means that there's an addition. This will be:

k + 7 = 34

k = 34 - 7

k = 27

Therefore, the value of k is 27
