What is the solution to this system?

Answers

Answer: There is no solution

Step-by-step explanation:

The system of a systems of equations on a graph is the coordinate where the 2 lines intersect, or come together. In this picture, the 2 lines don't intersect at a point, so there is no solution. Here are some rules for systems of equations on a graph:

How to know if it has 'infinite' solutions: If it has infinite solutions, the 2 lines share the same points. In other words, they are basically just on top of each other, or in the exact same spot.

How to know if there are 'no solutions': The 2 lines never come together (intersect). This is true in this graph because they are always apart.

How to know if there is 'one solutioin': The 2 lines cross each other, come together, or intersect (all the same meaning), at 1 point .

Hope this helps :)) Also brainliest would be appreciated :D

Xavier surveyed a random sample of the grade levels of the Spanish Club members in the county. The bar graph shows the results of his survey.

The bar graph is titled Random Sample of Spanish Club Members. The horizontal axis is labeled Grade level and lists four grades: ninth to twelfth. The vertical axis is labeled Number of members from zero to fourteen by twos. Ninth, eight. Tenth, fourteen. Eleventh, five. Twelfth, three.

Of the 300 students in the Spanish Club in the county, predict how many are 9th graders

Answers

Answer:

80

Step-by-step explanation:

If you add each value it equals 30.

30x10=300 so 8 (value of the 9th grade bar) times 10 equals 80.

I'm so sorry if this isn't right

Answer:

C. 50 (.20) + 20

Step-by-step explanation:

50 is the numbers of cookies so in order to find the total cost of JUST cookies we multiply 50 by .2 which is each cookies cost.

Then we add an additional 20 for the box.

So we get 50 (.2) + 20.

*BONUS* The total cost for one box is $30
