Answer:
Greatest number of hours = 3
Step-by-step explanation:
Given that:
Initial charges = $10
Per hour charges = $5
Number of hours = h
Equation;
t = 10 + 5h
For finding the hours for $25, we will put t=25 in the equation
25 = 10 + 5h
25 - 10 = 5h
5h = 15
Dividing both sides by 5
Hence,
Greatest number of hours = 3
It's c. PQRS is not rectangle because is has only 2 right angles.
One ∠PRQ and the other one is ∠SPR.
In order to be rectangle all 4 angles needs to be right angles.
1/24 or 4%
There is a total of 24 outcomes
4 letters • 6 numbers = 24 possible outcomes
There are 6 different outcomes when it comes to each letter.
(a1, a2, b1, b2 etc)
so getting a5 is a 1/24 chance because there 24 outcomes and only one of them is a5
Answer: Y = - 4 & x = 1
Step-by-step explanation:
Systems of linear equations: We will solve this using substitution but you can use 2 more ways.
7x + 2y = -1
2x - 4y = 19
Leave X alone first: -------------------
10x - 2y = 18
10x/10 = 18 + 2y/10
x = 9/5 + y/5
Solve for y:
7(9/5 + y/5) + 2y = -1
63/5 + 7y/5 + 2y - 1
63/5 + 7y/5 = 10y/5 = -1
63/5 + 17y/5 = -1 (-5/5)
17y/5 = -68/5 (cancel the 5)
y = -68/17
y = - 4 (Your Answer)
7x + 2(- 4) = -1
7x + (-8) = -1
7x = 7
x = 1
CHECK=
7(1) + 2(-4) = -1
7+ (-8) = -1.
-1=-1
26 ⋅ 26^8
Multiply by adding the exponents:
Raise 26 to the power of 1 to get:
26^1 * 26^8
Now when you multiply the same number raised to different powers, you add the powers together:
26^1 * 26^8 = 26^(8+1) = 26^9
So 26 * 26^8 simplifies is 26^9
