3. Mrs.Galicia bought 3 tacos and 2 sodas and paid $9.75. The next day she went back and bought 5 tacos and 1 soda and paid $12.

andrey2020 [161]

Answer:

a) 3x + 2y = 9.75, 5x + y = 12.75 is the required system of equations.

b) The cost of 1 soda = $1. 5

c) The cost of 1 taco = $2.25

Step-by-step explanation:

Let the cost of each taco = $x

Let the cost of each soda = $y

Now, according to the question:

3x + 2y = $9.75

5x + y = $12.75 are the required system of equations.

Now, substituting the value of y = 12.75 - 5x in (1).

⇒The equation 3x + 2y = 9.75 becomes 3x + 2(12.75 -5x) = 9.75

or, 3x - 10x + 25.5 = 9.75

or, -7x = -15.75

⇒ x = 15.75/7 = 2.25

Hence, the cost of 1 taco = $x = $2.25

Now, y = 12.75 - 5x

= 12.75 - 5(2.25) = 12.75 - 11.25 = = 1.5

or, y = $1.5.

Hence, the cost of 1 soda = $y = $1.5

The table shows linear relashonsips between x and y write an equation in slope intercept form for this relashonsip!!!!!!!!!!!!!!

Alchen [17]

Answer:

$y=-2x+6$

Step-by-step explanation:

Slope-intercept form is given as $y=mx+b$ , where $m$ is slope and $b$ is the y-intercept.

To find the slope of a line that passes through two points $(x_1, x_2)$ and $(y_1, y_2)$ , use the slope formula:

$m=\frac{\Delta y}{\Delta x}=\frac{y_2-y_1}{x_2-x_1}$

Let:

$(x_1, y_1)\implies (1, 4)\\(x_2, y_2)\implies (0, 6)$

The slope of the line that passes through these two points is:

$m=\frac{6-4}{0-1}=\frac{2}{-1}=-2$

Now substitute $m=-2$ and any point to solve for $b$ :

$y=mx+b,\\6=-2(0)+b,\\6=0+b,\\b=6$

Therefore, the slope-intercept form of a line that is represented by the table is $\boxed{y=-2x+6}$
