How many solutions does the system have?
amid [387]

Answer:

A; infinitely many solutions

Step-by-step explanation:

first, let's simplify the first equation to make it simpler.

divide both sides by 5

y=3x-8

new system

y=3x-8

y=3x-8

as you can see, they are the same.

not mandatory but useful!⬇⬇⬇⬇

just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.

3x-8=3x-8

add 8 to both sides; subtract 3x from one side

0=0

the answer is A, Infinitely many solutions.

hope this helped <3333333

The middle side of a triangle is half of 3 times the length of the shortest side. The longest side is 2 centimeters longer than
USPshnik [31]

<u>Answer:</u>  

The difference between the longest and shortest sides of the triangle is 4 cm.

<u>Explanation:</u>

<em>Step Number One:</em>

Let the shortest side of the triangle have a length of x.

The middle side of the triangle has a length that is half of 3 times the length of the shortest side. This can be written as 1/2*3x, which equals 3/2x.

The longest side of the triangle has a length that is 2 centimeters longer than the length of the middle side. This can be written as 3/2x + 2.

<em>Step Number Two: </em>

The perimeter of the triangle, which can be found by adding the lengths of all of the sides of the triangle, is 18 centimeters. This can be shown by the following equations:

Shortest Side + Middle Side + Longest Side = Perimeter

x + 3/2x + 3/2x + 2 = 18

4x + 2 = 18

4x = 16

x = 16/4

x = 4

<em>Step Number Three: </em>

This means that the shortest side of the triangle has a length of 4 centimeters and the longest side of the triangle has a length of 8 centimeters.

8 cm - 4 cm = 4 cm

Complete the table of inputs for the given function.
Alecsey [184]

Answer:

a. x = \frac{3}{8}

b. g(0) = 3

c. x = 1

d. g(3) = -21

Step-by-step explanation:

Given

g(x) = 3 - 8x

Solving (a): When g(x) = 0

Substitute 0 for g(x)

g(x) = 3 - 8x

0 = 3 - 8x

Solve for 8x

8x = 3

Solve for x

x = \frac{3}{8}

Solving (b): when x = 0

Substitute 0 for x

g(x) = 3 - 8x

g(0) = 3 - 8 * 0

g(0) = 3 - 0

g(0) = 3

Solving (c): When g(x) = -5

Substitute -5 for g(x)

g(x) = 3 - 8x

-5 = 3 - 8x

Solve for 8x

8x = 3 + 5

8x = 8

Solve for x

x = \frac{8}{8}

x = 1

Solving (d): When x = 3

Substitute 3 for x

g(x) = 3 - 8x

g(3) = 3 - 8 * 3

g(3) = 3 - 24

g(3) = -21
