Answer:y= 4/2x +1
Step-by-step explanation:
Slope is 4/2. Y-intercept is 1.
Answer:
y = 3x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 5 ← is in slope- intercept form
with slope m = 3
Parallel lines have equal slopes , then
y = 3x + c ← is the partial equation
To find c substitute (- 2, - 7 ) into the partial equation
- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1
y = 3x - 1 ← equation of parallel line
Answer:
-7x-3
Step-by-step explanation:
The second statement is correct. x represents the hours logged, so there were four hours logged. y represents the number of laptops built, so there would be 15 built.
(x, y) ——> (4, 15)
Answer:
17 1/2 months or rounded up to 18
Step-by-step explanation:
so first you need to set up an equation,
lets do company Q first..
because the monthly fee is 3 bucks thats gonna be the number that goes hand in hand with x so lets put that down
Q - 3x
now we have to add our one time fee of 25 dollars
Q - 3x + 25 .. bam thats our first equation
lets do the same thing for our next company
W - x + 60
( because the fee is one dollar, theres no reason to put 1x, its not mathematically correct, so we just leave it as x )
so now we have to set up the equation together, and because we are trying to find when the two will meet and have an EQUAL cost we make them equal to each other
so
3x + 25 = x + 60
if you solve it...
2x + 25 = 60
2x + 35
x = 17.5
