your answer is option 3.

you can also deduce it by option.

as in graph one line is dotted and one is solid that means 1 equation must have equality sign for solid line and one equation should not have equal sign for dotted line.

using this we can see only 3rd option has that.

your school sold 456 tickets for a high school play. An adult ticket cost $3.50. A student ticket cost $1. Total to ket sales eq

Svet_ta [14]

A + s = 456........a = 456 - s
3.5a + s = 1131

3.5(456 - s) + s = 1131
1596 - 3.5s + s = 1131
-3.5s + s = 1131 - 1596
-2.5s = - 465
s = -465/-2.5
s = 186 <====== student tickets sold

a + s = 456
a + 186 = 456
a = 456 - 186
a = 270 <==== adult tickets sold

noname [10]

Answer:

T = total #

T = 5 (to the aunt) + 1/2 (T - 5) (to his friends) + 1 (to his sister) + 4 (left)

T = 5 + 1/2 (T - 5) + 1 + 4

T = 10 + 1/2 (T - 5)

2T = 20 + (T - 5)

2T = 20 + T - 5

2T = 15 + T

T = 15

Which of the following represents the zeros of f(x) = 6x3 + 25x2 − 24x + 5?

cestrela7 [59]

F(-5) = 6(-5)^3 + 24(-5)^2 - 24(-5) + 5 = 0
so x = -5 is one zero.
