GrogVix [38]

Answer:

<u>System of equations</u>

x + y = 5

y - 2x = -4

(x,y) = (3,2) --- solution

See attachment for graph

Step-by-step explanation:

Solving (a): Linear equations with 1 solution

The only condition to this is that, the system must have 1 solution.

Other than that, there is no other condition.

A linear equation is represented as:

ax + by= c

For the equation to have 1 solution;

a_1 * b_2 \ne a_2 * b_1

And example of such equation is:

x + y = 5

y - 2x = -4

Solving (b): The graph

See attachment for graph

The solution is the point of intersection of both lines of the graph. So, we have:

(x,y) = (3,2)

oee [108]

Answer:

The markup rate on each box=41%

Step-by-step explanation:

The markup rate is the additional price that a good is sold at expressed as a percentage. This can be expressed as;

R={(S-C)/C}×100

where;

R=markup rate

S=selling price

C=cost

In our case;

R=unknown

S=$20.50

C=$14.50

replacing;

R={(20.5-14.5)/14.5}×100

R=(6/14.5)×100

R=41.38% rounded off=41%

The markup rate on each box=41%

For function one, the slope is already in mx+b form. The coefficient to x is the slope, so it is four in this case. For the second function we calculate the slope using rise over run. The rise is change in y and run is change in x, so 4/2= 2 slope. Four is greater than two so it has the greater rate of change. The answer is B
