Hey, I’m pretty sure the answer is y=1/2x + 0.
To explain, we can plug the x value into the equation for all of the x values, and we will get our y value.
So the first one,
y=1/2(1) + 0 —> 1/2
The second one,
y=1/2(2) + 0 —> 1
And so forth, the rest of the equations will be correct. I hope that helps ! :D
Answer:
see the explanation
Step-by-step explanation:
we know that
To calculate the slope we need to take two points from data in a table
point 1 (x1,y1) and point 2(x2,y2)
The formula to calculate the slope between two points is equal to
substitute the values and solve for m

Let "the number" = x
3x - 6 = 45 is your equation
Solve for x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
Isolate the x. First, add 6 to both sides
3x - 6 (+6) = 45 (+6)
3x = 51
Isolate the x. Divide 3 from both sides
3x/3 = 51/3
x = 51/3
x = 17
17 is your answer for "a number".

Answer:
7 cm, 16 cm, 19 cm
Step-by-step explanation:
Let s represent the length of the shortest side in cm. The longest side is 3s-2, and the other side is 2s+2. The perimeter is the sum of the side lengths.
P = s + (3s -2) +(2s +2)
42 = 6s . . . . . simplify, use the given value of perimeter
7 = s . . . . . . . divide by 6
2s+2 = 16
3s -2 = 19
The side lengths are 7 cm, 16 cm, and 19 cm.
