The solution to the system of equations is (0,2) since the solution is the point of intersection where two or more solid lines meet.

Answer:

The solution is (0,2)

Step-by-step explanation:

We have more than one way to solve a system of linear equations.

In this case, we have to linears (red and blue) given in their graphic form, so, we have to know that when we are solving a system of equations, we are looking for points in the plane where the functions have points in common. Then, we can see in the graphic that the red and blue linears match at x=0 and y= 2, so the answer to this system is (0,2).

Solve each system using SUBSTITUTION. Remember to check!

Annette [7]

Answer:

$\left \{ {{x=3} \atop {y=-7}} \right.$

Step-by-step explanation:

We can directly substitute y of the first equation to the second equation.

-2x - 1 = 3x - 16

5x = 15

x = 3

Substituting back to any of the two equations, we get y = -2(3)-1 = -7. If you check with the second equation, y = 3(3)-16 = -7 as well.

Therefore $\left \{ {{x=3} \atop {y=-7}} \right.$ .

All employees at three stores of a large retail chain were asked to fill out a survey.a. Is it random b. Systematic c. Stratifie

aleksandrvk [35]

Answer:

d. Cluster

Step-by-step explanation:

Random: Random is asking a group of people from a population. For example, to estimate the proportion of Buffalo residents who are Bills fans, you ask 100 Buffalo residents and estimate to the entire population.

Systematic: Similar to random. For example, you want to estimate something about a population, and your sample is every 5th people you see on the street.

Cluster:Divides the population into groups, with geographic characteristics.. Each element is the groups is used. Suppose you want to study the voting choices of Buffalo Bills players. You can divide into offense, defense and special teams, and ask each player of these 3 groups.

Stratified: Done on a group of clusters, that is, from each cluster(group), a number of people are selected.

In this problem, we have that:

All employees at three stores of a large retail chain were asked to fill out a survey.

Divided by clusters(stores).

So the orrect answer is:

d. Cluster

galina1969 [7]

Answer:

Step-by-step explanation:

Ok let start by putting a set amount of hats, let start with 12, 8 times 12 equals 96, 200-96 is 104… I would subtract 8 until you get a number you can divide equally by 10, 104-8=96, 96-8 =88 , 88-8=80, there is 80 dollars left! Ok 80 divide by 10 = 8 so

8 shirts and we’ll we started at 12 and then we add how many more time we subtracted 8 so 15 total,

So, in total 8 shirts and 15 hats!!!
