Answer is b
4000/12 = 333
333+80 = 413
413*20= 8260 they have enough
400/12=333
333*22= 7326 not enough
Answer:
y=-3
x=1
(1,-3)
Step-by-step explanation:
5x+4y=-7
-5x-2y=1
Cancel +5x - 5
2y=-6
y=-3
5x-12=-7 or -5x+6=1
5x=5 -5x=-5
x=1 x=1
you would add 4x-3 to 6x-6 and equal it to 180° which is 6x+4x-6-3=180° which is 10x-9=180° then use inverse operation to solve it.
Answer: 18.9
Answer:
Step-by-step explanation:
Tables show linear functions.
The slope-intercept form of an equation of a line:
<em>m</em> - slope
<em>b</em> - y-intercept → (0, b)
The formula of a slope:
===================================================
Table 1:
(0, 1) → b = 1, (1, 5)
Table 2:
(4, 1), (6, 2)
Put the coordinateso f the point (4, 1) to the equation of a line:
<em>subtract 2 from both sides</em>
