Answer:
For the function 
the average rate change from x is equal 1 to x is equal 2 is 4 .
Step-by-step explanation:
A function is given f(x)=4x-3.
It is required to find the average rate change of the function from x is 1 to x is 2 . simplify.
Step 1 of 2
A function f(x)=4 x-3 is given.
Determine the function 
by putting the value of x=1 in the given function.
Determine the function by putting the value of x is 2 in the given function.
Step 2 of 2
According to the formula of average rate change of the equation 
Substitute the value of with, with 
with 2 and 
with 1 .
Given that ∠B ≅ ∠C.
to prove that the sides AB = AC
This can be done by the method of contradiction.
If possible let AB 
=AC
Then either AB>AC or AB<AC
Case i: If AB>AC, then by triangle axiom, Angle C > angle B.
But since angle C = angle B, we get AB cannot be greater than AC
Case ii: If AB<AC, then by triangle axiom, Angle C < angle B.
But since angle C = angle B, we get AB cannot be less than AC
Conclusion:
Since AB cannot be greater than AC nor less than AC, we have only one possibility. that is AB =AC
Hence if angle B = angle C it follows that
AB = AC, and AB ≅ AC.

Step-by-step explanation:
Answer:
he should buy 128 oz of milk for 6.49
Step-by-step explanation:
2.49 divided by 32 equals 7 cents unless your rounding which would be 8 cents
4.99 divided by 64 is 7 cents too 8 if rounding
6.49 divided buy 128 oz would equal 5 cents so it is the cheapest.
Rewrite the equation:
-2x^2 - 3x + 8 = 0
2x^2 + 3x -8 =0
Where a=2, b=3 and c=-8
Then b^2 - 4ac = 3^2 - 4(2)(-8) = 9 + 64 = 73
A positive discriminant implies that the equation has two different real solutions.
Answer: the discriminant is 73, so the equation has 2 real solution
