When determining intercepts algebraically what does it mean if you get an imaginary solution?

mr_godi [17]

When determining intercepts algebraically and you get an imaginary solution, this would mean that the graph of the function does not pass through the x or the y axis. X-intercept is the value of x when y would be equal is zero or the value x when the graph passes/ intersects the x-axis. On the other hand, the y-intercept is the value of y when x is zero or the value of y when the plot intersects the y-axis. Therefore, the value of these intercepts should be real values and not imaginary numbers or else these intercepts do not exist. The plot of the equation would not cross any of the axes in the coordinate.

Question 2 of 10<br> How many solutions are there to the equation below?<br> 11x + 25 = 7x + 15

Irina18 [472]

One solution
11x + 25 = 7x+15
-7x -7x

4x+25=15
-25 -25

4x= -10
————
4

x= -10/4

-10/4 simplified is -5/2

so there is one solution where x=-5/2

(b) The treatment group is the group that exercises 2 times a week, whereas the control group is the group that does not exercise.

The blocking variables are 18-30-year-olds, 31-40-year-olds, and 41-55year olds.

(d) No, the study under consideration did not make use of blinding because the patients know if they are in the group that exercises or the one that doesn’t.

nlexa [21]

Answer:

The price of one pound of coffee is 32 pesos

The price of one pound of sugar is 7 pesos

Step-by-step explanation:

The question in English is

6 pounds of coffee and 5 pounds of sugar cost 227 pesos and 5 pounds of coffee and 4 pounds of sugar (at the same prices) cost 188 pesos Find the price of one pound of coffee and one pound of sugar.

Let

x-----> the price of one pound of coffee

y-----> the price of one pound of sugar

we know that

6x+5y=227 -----> equation A

5x+4y=188 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution is the point (32,7)

see the attached figure

therefore

The price of one pound of coffee is 32 pesos

The price of one pound of sugar is 7 pesos
