Answer: (19,520-1,478) x 8
Answer:
First one
Step-by-step explanation:
First one, because one x-value can't have two y-values.
A function always outputs one y-value. But it can have two x-values for one y-value.
Hope this cleared things up for you!
Answer:
The equation of the line would be y = -1/4x + 2
Step-by-step explanation:
In order to solve this, start by finding the slope of the original line. You can do this by solving for y.
28x - 7y = 9
-7y = -28x + 9
y = 4x - 9/7
Now that we have a slope of 4, we know that the perpendicular slope is -1/4 (since perpendicular lines have opposite and reciprocal slopes). We can use this and the new point in point-slope form to find the equation.
y - y1 = m(x - x1)
y - 1 = -1/4(x - 4)
y - 1 = 1/4x + 1
y = -1/4x + 2
Answer: 9
Step-by-step explanation: 7, 9, 11, 13 are the consecutive odd numbers that equal 40 as you can tell i put the numbers in order so you know what number is what so your answer is 9. If this helps reply back.
