It is c = 48b.
2 x 48 = 96
4 x 48 = 192
9 x 48 = 432
Answer:
b. y-y1 = m(x-x1)
Step-by-step explanation:
It's a matter of definition. There are perhaps a dozen useful forms of equations for a line. Each has its own name (and use). Here are some of them.
- slope-intercept form: y = mx + b
- point-slope form: y -y1 = m(x -x1)
- two-point form: y = (y2-y1)/(x2-x1)(x -x1) +y1
- intercept form: x/a +y/b = 1
- standard form: ax +by = c
- general form: ax +by +c = 0
Adding y1 to the point-slope form puts it in an alternate form that is useful for getting to slope-intercept form faster: y = m(x -x1) +y1. I use this when asked to write the equation of a line with given slope through a point, with the result in slope-intercept form.
Slope-intercept:
y=mx+b
5x-y=9
5x=y+9
y+9=5x
y=5x-9
Slope-int: y=5x-9
Hello, we know there are 12 inches in one foot, so in 12 feet, there are 144 inches.
Answer:
x ≤ 1
Step-by-step explanation:
First, add 5 to both sides (we want to isolate x).
3x ≤ 3
Now, we divide by 3.
x ≤ 1
That's the answer! All values equal to or less than 1 are solutions of 3x - 5 ≤ -2.
Hope this helps
