Answer: B.
Step-by-step explanation:
Answer:
- 150 short-sleeved shirts
- 100 long-sleeved shirts
Step-by-step explanation:
Let S and L represent the numbers of short- and long-sleeved shirts ordered.
The expected earnings were ...
5S +10L = 1750
The number sold was ...
(1/3)S + (1/2)L = 100
We can multiply the first equation by 1/5 and the second equation by 6 to put the equations into standard form:
Subtracting the second equation from twice the first gives ...
2(S +2L) -(2S +3L) = 2(350) -(600)
L = 100 . . . . . . simplify
2S +3(100) = 600
S = 150
150 short-sleeved and 100 long-sleeved shirts were ordered.
First we distribute the negative throughout the last polynomial:
Combine like terms:
Answer:
y = - 9x + 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 )
here m = - 9, hence
y = - 9x + c ← is the partial equation
To find c substitute (1 , - 8) into the partial equation
- 8 = - 9 + c ⇒ c = - 8 + 9 = 1
y = - 9x + 1 ← equation of line
Answer:
Step-by-step explanation:
All you gotta do is subtract - b + c from both sides then simplify.
