Answer:
y = -4x + 10
Step-by-step explanation:
The proper formula is:
y = mx + b
It's the slope of the secant line to <em>f(x)</em> through the points (-3, <em>f</em> (-3)) and (9, <em>f</em> (9)),
Answer:
x= -6 twice
Step-by-step explanation:
x^2-3x-10/x^2+12x+36
By using undefined fraction we only take the denominator and equate it to 0
x^2+12x+36=0
x^2+6x+6x+36=0
(x^2+6x)+(6x+36)=0
x(x+6)+6(x+6)=0
(x+6)(x+6)=0
x+6=0 or x+6=0
x= -6 or x= -6
therefore x= -6 twice
Answer:
The barge can carry up to 94 railroad cars.
Step-by-step explanation:
Create an inequality to represent the weight of the barge to the max weight.
24 + 4r ≤ 400
Solve for r:
4r ≤ 400 - 24
4r ≤ 376
4r ≤ 376/4
r ≤ 94
I hope this helps you
-3x+2y= -10
3x-2y=14
-3x+2y+3x-2y= -10+14
0+0= 6
0=6 false it's not inconsistent
