Answer:
57, 58, 75, 78, 85, 87 (no repeats)
add 55, 77, 88 to the above list if repeats are allowed.
Step-by-step explanation:
With no repeating digits, there are 3 ways to choose the first digit, and 2 ways to choose the second digit, for a total of 3×2 = 6 possible numbers
57, 58, 75, 78, 85, 87
If the digits can be repeated, than you can add 55, 77, 88 to that list:
55, 57, 58, 75, 77, 78, 85, 87, 88
Answer:
y = 4/5x - 9/5
Step-by-step explanation:
4x - 5y = 9 to solve for y you get it by itself.
-4x -4x minus 4x from both sides
-5y = - 4x + 9
/-5 /-5 Divide both sides by 5
y = 4/5x - 9/5 because -4/-5 is 4/5 and 9/-5 is - 9/5
Length (L): 2w + 3
width (w): w
border (b): 
Area (A) = (L + b) * (w + b) <em>NOTE: This is assuming the width also has a border</em>
= (2w + 3 + ) * (w + )
=

Answer:
-2
Step-by-step explanation:
m=-(5/4)
From left to right, (1,3) is first and then comes (5,-2). Always remember when finding slopes without equations, the rule is RISE over RUN, to the numerator and denominator, respectively.
The y value of the second coordinates becomes negative which is unlike the y value in the first coordinates, which means our slope is downward, meaning it has a negative sign in front.
In every slope, there’s a numerator, being the rise, and a denominator, being the run.
To find the rise, we must look at the y values. Starting at 3 going to -2 has a space of 5 units, making that our numerator.
To find the run, the first x value is 1 and the second is 5, making a space of 4, which is out denominator.
With these two numbers and the negative sign, we get -(5/4) as our slope.
