Answer: a = 22
Step-by-step explanation: First isolate a/3 by adding 7 to both sides of the equation. That gives you a/3 = 22.
From here since <em>a</em> is being divided by 3, multiply both sides of the equation by 3 so <em>a</em> <em>= 66</em>. We can check our answer by substituting a 66 back in for <em>a</em> in the original equation and we have 
or 22 - 7 = 15 or 15 = 15. Since this is a true statement, our answer checks.

Answer: 9.3
Step-by-step explanation:
Y int at (0,4).....thru points (4,1)
slope = (1 - 4) / (4 - 0) = -3/4
initial value 4, slope(rate of change) is -3/4 <==
=======================
y = 22,000x + 40,000
=======================
y = 12x + 48
slope(rate of change) = 12
=======================
(1,10)(2,8)
slope = (8-10) / (2-1) = -2/1 = -2
y = mx + b
8 = -2(2) + b
8 = -4 + b
8 + 4 = b
12 = b
slope(rate of change) = -2
initial value = 12
I am not getting any of ur answer choices ...
======================
y = x + 6
initial value = 6
Answer:
Ix - 950°C I ≤ 250°C
Step-by-step explanation:
We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.
And that this temperature is x.
This means that the minimum value of x is 700°C while maximum of x is 1200 °C
Let's find the average of the two temperature limits given:
x_avg = (700 + 1200)/2 =
x_avg = 1900/2
x_avg = 950 °C
Now let's find the distance between the average and either maximum or minimum.
d_avg = (1200 - 700)/2
d_avg = 500/2
d_avg = 250°C.
Now absolute value equation will be in the form of;
Ix - x_avgI ≤ d_avg
Thus;
Ix - 950°C I ≤ 250°C
