Which set of equations would have infinitely many solutions? JUSTIFY your answer in #4.

Mathematics

Ierofanga [76]2 years ago

Answer:

2nd option: 2y=6x+8 and y=3x+4

Step-by-step explanation:

If you divide the first by 2, you get the second equation.

This means that both equations plot an identical line (they lie on top of each other /also known as "coincide"). This means, that there are infinitely many solutions.

In 2D (x-y plane for example), straight lines can have no solutions if they have the same gradient/slope/ they are parallel and different y-intercepts, because they will never cross.

Here, they have same gradient and y-intercept so all points on the line are valid solutions to the equation

The pitchers for the home team had 12 strikeouts for 32 batters, while the pitchers for the visiting team had 15 strikeouts for
dimulka [17.4K]

Answer:

I disagree with the other answer.

Step-by-step explanation:

The reason for this is because if you have 12/32 for team 1, and 15/35 on team 2, then you do cross products(a type of shortcut).

12/32   15/35

1) Multiply 12 and 35= 420

2) Multiply 15 and 32= 480

3) Which number is greater?

<u>Answer</u>

<em>TEAM 2</em>..(or the visiting team)

Answer:

174 inches squared

Step-by-step explanation:

First, we have to remember what the area of a triangle is:

\frac{base*height}{2}

Since there are 4 of the same triangle, multiply the area of one triangle by 4:

\frac{10*8.7}{2}

\frac{87}{2}

43.5

43.5(4)=174
