Answer:

The correct equation form for finding the price of a sandwich is 5x + 1.25 = 38.75 and the cost of each sandwich was $ 7.50

Step-by-step explanation:

1. Let's check all the information given for solving this question:

Cost of bag of chips = $ 1.25

Cost of sandwich = x

Cost of total order = $ 38.75

2. The formula for find the cost of sandwich (x) is this:

5x + 1.25 = 38.75 (Joaquin ordered 5 sandwiches and a bag of chips)

5x = 37.50 (Subtracting 1.25 at both sides)

5x/5 = 37.50/5 (Dividing by 5 at both sides)

x = 7.50

The cost of each sandwich was $ 7.50

4 = 2/4u

Multiply both sides by 4u

16u = 2

Divide both sides by 16, and simplify.

u = 1/8

y^2 = 30

y = 5.5

x/5 = 17/x

x^2 = 85

x = 9.2

Write an equation in slope intercept form that goes through (-1,6) and (3,-2)

pochemuha

<h2>Answer:</h2>

First, we need to use slope formula* to find the slope.

$m = \frac{-2 - 6}{3 - (-1)} = \frac{-8}{4} = -2$

Second, we use the slope we found and ONE of the 2 points listed and plug it into slope-intercept form** to solve for b.

Here is what we have so far:

$m = -2$

I'm going to use this point:

$x = 3$

$y = -2$

Here is how to find b:

$-2 = -2(3) + b\\\\-2 = -6 + b\\\\4 = b$

Finally, we put all of it together and we have our equation.

$y = -2x + b$

*Slope formula: m = y₂ - y₁/x₂ - x₁

**Slope-intercept form: y = mx + b
