No because 18 don't have a n or m
<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:
By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
A.) it's a 90° angle
90=6x+4x+10
90=10x+10
-10 -10
80=10x
divide both sides by 10, x=8
B.) it's a 180° angle
180=5x+13+3x+7
180=8x+20
-20 -20
160=8x
divide both sides by 8, x=20
C.) it's a 180° angle
180=3x+5+2x+18+2x+17
180=7x+40
-40 -40
140=7x
divide both sides by 7, x=20
D.) it's a 180° angle
180=90+30+x
180=120+x
-120 -120
60=x
Answer:
is this even real what's the actual question?
Answer: -2
Step-by-step explanation: The average rate of a function f(x) from x=a to x=b is given as:
Clearly we are asked to find the average rate of change from x=0 to x=2.
i.e. a=0 and b=2
Also, from the graph it could be observed that:
f(0)=1
and f(2)=-3
Hence, the average rate of change is calculated as:
Hence, the average rate of change for this quadratic function for the interval from x = 0 to x = 2 is:
-2
