2x+8y = 6 15x + 20y = 15

Mathematics
1 answer:
Likurg_2 [28]3 years ago
4 0

Answer:

The solution is (0, 3/4)

Step-by-step explanation:

Please copy and share the instructions.  Here they are:  Solve the following system of linear equations.

Both of the equations can be reduced (simplified):

2x+8y = 6            =>  x + 4y = 3

15x + 20y = 15     => 3x + 4y = 3

Let's use the elimination by addition and subtraction method.  Multiply the first equation by -1, obtaining

                                 -x - 4y = -3

Add the second       3x + 4y = 3

equation to the

first.

We get:                       2x = 0.

Thus, x = 0.  Substituting 0 for x in the 1st original equation yields:

2(0) + 8y = 6.  Then y = 6/8, or y = 3/4.

The solution is (0, 3/4).

If g(x) = 4x - 3 and h(x) = -4x, what is g(5) + h(3)?
elena55 [62]

Answer:

g(5) + h(3) = 5

Step-by-step explanation:

g(5)

g(5) = 4(5) - 3\\\rule{150}{0.5}\\g(5) = 20 - 3\\\\\boxed{g(5)=17}

h(3)

h(3) = -4(3)\\\rule{150}{0.5}\\\boxed{h(3) = -12}

g(5) + h(3)

17 + -12\\\rule{150}{0.5}\\17 - 12\\\\\boxed{5}

Hope this helps.
