Use the equation y+4=3x
to fill in the missing values in the table below. (Type in the numbers for your answers, do not spell the number out, or it will count it wrong.)
X side in order: -7, blank, 0, blank
Y side in order: blank, 8, blank, -34
Using the equation y + 4 = 3x, we can calculate the missing values in the table:
For the first blank on the X side:
-7 + 4 = 3x
-3 = 3x
x = -1
For the second blank on the X side:
0 + 4 = 3x
4 = 3x
x = 4/3
For the first blank on the Y side:
y + 4 = 3(-7)
y + 4 = -21
y = -25
For the second blank on the Y side:
y + 4 = 3(0)
y + 4 = 0
y = -4
Filling in the values in the table, we have:
X side in order: -7, -1, 0, 4/3
Y side in order: -25, 8, -4, -34
To fill in the missing values in the table using the equation y+4=3x, we can substitute the given x values into the equation and solve for y.
First, let's find the missing value of x. We already have x=-7 and x=0. To find the second missing value of x, we can substitute the first y value into the equation.
For the first y value (blank) when x=-7:
y + 4 = 3(-7)
y + 4 = -21
y = -21 - 4
y = -25
So, the missing value in the x column is -25.
Now, let's find the missing value of y. We already have y=8. To find the second missing value of y, we can substitute the second x value into the equation.
For the second y value (8) when x=-25:
y + 4 = 3(-25)
y + 4 = -75
y = -75 - 4
y = -79
So, the missing value in the y column is -79.
Now we have the complete table:
X side in order: -7, -25, 0, blank
Y side in order: -25, 8, -79, -34
To fill in the missing values in the table, we can substitute the given values of y and x into the equation y + 4 = 3x.
Let's calculate the missing values step by step:
For the first missing x value, we can rearrange the equation to isolate x:
y + 4 = 3x
3x = y + 4
x = (y + 4)/3
We are given that y is -34, so let's substitute that in:
x = (-34 + 4)/3
x = -30/3
x = -10
For the second missing y value, we can substitute the given x value of 0 into the equation:
y + 4 = 3(0)
y + 4 = 0
y = 0 - 4
y = -4
So, the filled-in table would look like this:
X side in order: -7, -10, 0, blank
Y side in order: -4, 8, blank, -34
