Answer: i dont know
Step-by-step explanation:
Hi!
30 = x
f(x) = -1/5x - 14 find x when f (x) = -8
Set the equation equal to -8
-8 = -1/5x - 14
Add 14 to both sides.
6 = -1/5x
Multiply both sides by -5.
30 = x
Hope this helps! :D
Answer:
Step-by-step explanation:
a) Meal price | Remaining
$15 | $37.75
$21 | $30.85
$24 | $27.40
$30 | $20.50
b) (20.5 - 27.4)/(30-24) = -6.9/6
f(m) = 55 - 1.15m = -1.15m + 55
c) Use a graphing utility
Answer:
Step-by-step explanation:
Step 1: rewrite the equation of the given line in to slope-intercept form by solving for y
3y + 5x = 6
3y = -5x + 6 (subtract 5x from both sides)
y = -(5/3)x + 2 (divide both sides by 3)
Step 2: Our line is parallel to this line, so it has the same slope, and a
y-intercept of 4, so we have...
y = -(5/3)x + 4
*slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept,
Answer:
a
Step-by-step explanation:
it has to have to same slope as the first equation so you have y=5x+b then what you do is plug in the points and solve for b. which gives you 2. so your final equation is y=5x+2
7=5+b
-5 -5
2=b
