Answer:

The answer is below

Step-by-step explanation:

a) To complete the table of values for y = 3x - 1, we substitute the value of x into the equation and find y.

For x = -2, y = 3(-2) - 1 = -7; For x = -1, y = 3(-1) - 1 = -4

For x = 0, y = 3(0) - 1 = -1;    For x = 1, y = 3(1) - 1 = 2

For x = 2, y = 3(2) - 1 = 5;    For x = 3, y = 3(3) - 1 = 8

x:    -2      -1        0        1         2       3

y:    -7      -4       -1        2         5      8

b) The graph is drawn using geogebra online graphing calculator.

c) From the graph, When x = 2.5, y = 6.5

At a concession stan,one hot dog and one hamburger cost $2.75, one hot dog and seven hamburgers cost $11.75. Find the cost of on
lawyer [7]
Variables:
cost of 1 hot dog = x
cost of 1 hamburger = y

Set up a system of equations and use substitution

x + y = 2.75
x + 7y = 11.75

x + y = 2.75 can be rewritten as y = -x + 2.75

x + 7 (-x + 2.75) = 11.25

-6x + 19.25 = 11.25

-6x = -8

x = .75

plug x back into other equation to find y

y = -.75 + 2.75

y = 2.00

1 hot dog = $0.75
1 hamburger = $2.00

PLS HELP ASAP!
ddd [48]

Answer:

Step-by-step explanation:

either way works, but I would suggest adding 4x to each side so that the "x" value stays postive. Keeping the "x" positive when possible always helps me.

it becomes:

10x=4

x=4/10

x=2/5

{ \qquad\qquad\huge\underline{{\sf Answer}}}

Let's solve ~

\qquad \sf  \dashrightarrow \: 3(x + 2) =  - 5 - 2(x - 3)

\qquad \sf  \dashrightarrow \: 3x + 6 =  - 5 - (2x - 6)

\qquad \sf  \dashrightarrow \: 3x + 6 =  - 5 - 2x + 6

\qquad \sf  \dashrightarrow \: 3x  + 6 =   - 2x + 1

\qquad \sf  \dashrightarrow \: 3x + 2x = 1 - 6

\qquad \sf  \dashrightarrow \: 5x =  - 5

\qquad \sf  \dashrightarrow \: x =  - 5 \div 5

\qquad \sf  \dashrightarrow \: x =  - 1
