For this case we have the following system of equations:
$y = -0.25x + 4.7

y = 4.9x-1.64$
When solving the problem graphically we must take into account the following:
1) The solution of the system of equations is given by the intersection of both functions.
2) The solution is an ordered pair of the form (x, y)
For this case we observe that the solution is given by:
$(x, y) = (1.23, 4.39)
$
Note: see attached image.
Answer:
The approximate solution to the system is (1.23, 4.39)

Complete the pairs of corresponding parts if △ABD ≅ △EFC.

vovangra [49]

Answer:

We conclude that:

∠A = ∠ FEC

Step-by-step explanation:

Given

△ABD ≅ △EFC

To determine:

∠A =

△ABD ≅ △EFC

So the triangles △ABD and △EFC are congruent to each other.

We know that congruent triangles have equal corresponding parts.

Please check the attached graph.

From the graph, it is clear that ∠A is correspondent to ∠E.

∠A = ∠E

From the attached figure, it is clear that:

∠F can also be denoted by ∠ FEC

∠A = ∠E

∠A = ∠ FEC

Therefore, we conclude that:

∠A = ∠ FEC

Camden is working two summer jobs, making $10 per hour babysitting and making $18 per hour lifeguarding. In a given week, he can

nirvana33 [79]

Answer:

2 hours babysitting

Step-by-step explanation:

First you would multiply 14 by 9 and you would get 162

Then you would Subtract 180 by 162 and you would get 18

So than you would keep on multiplying 10 till you get 20 which would be 2

So therefore your answer would be 2

seven different gifts are to be distributed among 10 children. How many distinct results are possible if no child is to receive

Alik [6]

Answer:

120 distinct results are possible if no child is to receive more than one gifts.

Step-by-step explanation:

When the order is not important, we use the combination formula:

$C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

The order is said to be not important if for example, John receiving the Buffalo Bills jersey and then Laura receiving the Cleveland Browns jersey is the same as Laura receiving the Cleveland Browns jersey before John receives the Buffalo Bills jersey.

In this problem, we have that:

Combinations of 7 from a set of 10 elements. So

$C_{n,x} = \frac{n!}{x!(n-x)!}$

$C_{10,7} = \frac{10!}{7!(3)!} = 120$

120 distinct results are possible if no child is to receive more than one gifts.
