Answer:
13
Step-by-step explanation:
Take any two corresponding values, say (3,7) and (9,16)
Calculate the gradient of the linear function
Gradient=[16-7]/[9-3]=9/6=3/2
find the equation or rule of the linear mapping
y-7=(3/2)(x-3)
y=3x-9+7
y=(3/2)x+5/2
Answer: No, No, Yes, Yes, Yes
<u>Step-by-step explanation:</u>
At 2:15 the temperature is 7°
It decreases 3° every 15 minutes ⇒ -3
Here is a table:
time | temperature
2:15 | 7
2:30 | 7 - 3 = 4
2:45 | 7 - 3 - 3 = 1
3:00 | 7 - 3 - 3 - 3 = -2
3:15 | 7 - 3 - 3 - 3 - 3 = -5
3:30 | 7 - 3 - 3 - 3 - 3 - 3 = -8
Do you see a pattern? This can be written as:
7 + (-3) + (-3) + (-3) + (-3) + (-3) + (-3)
7 - (3)(5)
7 + 5(-3)
Answer: -6/3+1/3
Step-by-step explanation: Just solve all the problems until you find one that is not the same answer :)
Answer:
7z
Step-by-step explanation:
subtracting a negative is like adding
Answer:
7/9+1/6+2/3+6/18=28/36+6/36+24/36+12/36
=70/36
=1/34/36
