Answer:

C. 43.11°

Step-by-step explanation:

The formula to use in finding m<BCD = ½ the difference of the intercepted arcs AE and BD

Thus:

m<BCD = ½(AE - BD)

m<BCD = ½(112.54 - 26.32)

m<BCD = ½(86.22)

m<BCD = 43.11°

The total of two numbers is 28. Four times the smaller number is 7 more than three times the larger number.
navik [9.2K]
Let's define:
x \ \textless \ y

So, you can set up a system of equations:
x + y = 28
4x = 7 + 3y

Now, to solve for both of those values, solve the system of equations:
x = 28 - y
4(28-y) = 7+3y
122-4y=7+3y
115 -4y = 3y
115 = 7y
y = 16.43

Now, plug that y-value into the first equation to solve for x:
x + 16.43=28
x = 11.57

Now, we have both the values. The smaller value (x) = 11.57 and the bigger value (y) = 16.43.

Please help, I can't figure this out for the life of me!

B≠1
constant a = 25

If b was 1, then it would not be exponential. The f(x) would stay as a, which is the starting number, or number at an x of 0. In the table, this would be 25.

f(x) = 4 X 3 + 3 X 2 + 5x + 7

It can be represented as follow: x² X 3 + 3 X 2 + 5x + 7

3x² + 6 + 5x + 7

3x² + 5x + 13

EASY PLEASE HELP WILL GIVE BRAINLIEST
kenny6666 [7]

Answer: 5h+4=A

Step-by-step explanation:

She gets five dollars an hour so for one hour she gets five dollars, for two hours she gets 2 times 5 dollars (10 dollars), for three hours she gets 3 times 5 dollars (15 dollars) etc...

Now replace the 1,2,3... with the variable representing the hour. In this case it would be h. So 5h=five dollars per hour. Because you only put the kid to bed once, you add four at the end
