Answer:
1, 4, and 5
Step-by-step explanation:
1 is correct because 5*5=25*4=100
2 is incorrect because 5*5=25*5=125
3 is incorrect because 5*4=20*4=80
4 is correct because 5*20=100*1=100
5 is correct because 5*2=10*10=100
6 is incorrect because 5*10=50*10=500
4x + 12x = 320
16x = 320
x = 20
Answer:
option C is correct

Answer:
Graph # 3
Step-by-step explanation:
-2x + 5y > 15 Let x = 0 solve for y
-2(0) + 5y = 15 change the > to an =
5y = 15
y =3 Point (0, 5) is on the graph
Graph # 3 is correct because the y-intercept is 5
x y
0 3 -2(0) + 5y = 15; 5y = 15
5 5 -2(5) + 5y = 15; -10 + 5y = 15; 5y = 25; y = 5
10 7 -2(10) + 5y = 15; -20 + 5y = 15; 5y = 35; y = 7
The graph > the line is dotted and you will shade above the line
<span>×^2+5×-24=0
(x+8)(x-3) = 0
x+8 = 0, x = -8
x - 3 = 0, x = 3
answer: </span>x = -8 and x =3
