Answer:
35
Step-by-step explanation:
x + 10 + 3x - 5 + x = 180
5x + 5 = 180
5x = 175
x = 35
The equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
Step-by-step explanation:
Step 1; We need to determine the equation relating the x to the f(x) values from the given coordinates. y is the dependent value whereas x is the independent value i.e. y's value depends on x's value.
Step 2; If we multiply the x value with 2 and add the resulting answer with 1 we get the y value.
y = 2x + 1 is the equation that relates the values in the table.
Step 3; Now we substitute the values in the equation to see if it's correct.
For x = 0, y = 2(0) + 1 = 0 + 1 = 1,
For x = 2, y = 2(2) + 1 = 4 + 1 = 5,
For x = 3, y = 2(3) + 1 = 6 + 1 = 7.
So the equation that gives the coordinates (0,1), (2,5), (3,7) is y =2x + 1.
Answer:
y=-3x-2
Step-by-step explanation:
y=mx+b
y=-3x+b
y=3x-2
m is the slope, b is the y intercept
