Rhoda is asked to graph this system of equations: 5x - 6y = 4 3y + 2x = 7 How many times will the lines intersect? O A. The line

Daniel [21]

Answer:

C. The lines will intersect once, because this system has one solution

Step-by-step explanation:

System of equations:

5x - 6y = 4
3y + 2x = 7

The system of linear equations has one solution if the lines intersect, no solution if the lines are parallel, infinitely many solutions if lines are same

Let's put the lines into slope-intercept form to compare

Line1

5x - 6y = 4
6y = 5x - 4
y = 5/6x - 4/6

Line 2

3y + 2x = 7
3y = -2x + 7
y = -2/3x + 7/3

As we see lines have different slopes so they are different and they intersect once

This system has one solution

Suppose the linear regression line y = 4.009x - 77.531 predicts a pizza

fredd [130]

Answer:

Option C, 1225

Step-by-step explanation:

y=4.009x-77.531

selling 325 pizzas, so x=325, now putting the value of x in the equation,

y=4.009×325-77.531

or, y=1225.394

y = 1225.394, which is the profit, if we approximate it to the nearest value, it's $1225
