Step-by-step explanation:
m = y2 - y1/ x2 - x1
= 16 - 12 / 16 - 4
= 4/12 = 1/3
formula = y - y1 = m2 ( x - x1)
y - 12 = 1/3 ( x - 4)
y -12 = 1x/3 -4/3
y = 1x / 3 -4/3+12
= 1x/3 + 32/ 3
y = 1x/3 + 32/3
4.25 years old. or 4.3 years if you're rounding up
Answer:
<h3>16</h3>
Step-by-step explanation:
Given the equation y = 8x
From the table, we are to find the value of y when x = 2
when x = 2;
y = 8(2)
y = 8 * 2
y = 16
Hence the value that completes the table is 16
X^5 = 1024 = 4^5
Therefore, x = 4.
Given, (-1/7)^-x = -1/343
(1/7)^-x = 1/343
(1/7)^-x = (1/7)^3
-x = 3
x = -3
