If each unit on the grid represents 2.5 inches, find the height of the triangle.

Answer:

Times four then Minus 2

Step-by-step explanation:

1 times 4 is 4 then minus 2 is 2

Answer:

Step-by-step explanation:

To solve the system using elimination, first multiply the bottom equation by 2. Write the new system of equations. (1 point)

5x + 2y = 7

6x –2y = 4

Why is this multiplication allowed? (1 point)

Because the entire equation was multiplied by the same number, the equation remains the same.

What variable will be eliminated when the equations are combined after  the multiplication? (1 point)

The Y variable

Next, add the equations together. Your answer should be a single equation with one variable. (1 point)

11x = 11

Solve the equation for x. (1 point)

X = 1

What is the solution to the system of equations? (1 point)

X = 1 and Y = 1 so the answer is (1, 1)

(If you solve this again, but eliminate the X variable, you will still receive that answer 1, so Y = 1)

Sorry my first answer was wrong

Answer:

  3 : 1

Step-by-step explanation:

The ratio of coins is ...

  1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5

The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...

  5(3) : 5 = 3 : 1

The quarters have 3 times the dollar value of the nickels.

__

Additional comment

The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.

The dollar value of the quarters is 24($0.25) = $6.

The dollar value of the nickels is 40($0.05) = $2.

As above, the ratio of dollar values is 6:2 = 3 : 1.

There are a few different ways to compute the ratio of fractions. The one we used here may be a little unusual. All are equivalent.

Answer:

Correlation

Step-by-step explanation:

I think

The relationship between the two events is one of implication (Option D.), where achieving 12 consecutive strikes implies the occurrence of a perfect game, but it does not necessarily indicate a causal or universally correlated relationship.

The term that best describes the relationship between the two events described is implication.

In this context, the statement implies that when a bowler achieves 12 consecutive strikes in a game, it is an indication or implication that the bowler has bowled a perfect game. This means that if the first event (getting 12 consecutive strikes) occurs, it logically leads or implies the occurrence of the second event (bowling a perfect game). However, it does not necessarily mean that every perfect game is achieved through 12 consecutive strikes, as there can be alternate ways to achieve a perfect game.

Therefore, the relationship between the two events is one of implication, where the occurrence of the first event suggests or implies the occurrence of the second event, but they are not always causally linked or universally correlated.

Answer:

See below:

Step-by-step explanation:

Hello! I hope you are having a nice day.

We can solve this equation in a single step, we just need a bit of theory and a graph.

We can first see that its in [tex]y=mx+b[/tex] form. Which is also known as Slope-Intercept form.

This means that we know the following.

Since we know that, we can see that from our equation that the slope of the line is 3 and the y intercept is (0,-7).

Now that we've gotten that, we can start graphing.

The y intercept is -7 so we can plot (0,-7) as one of our points.

The slope of 3 means that we got up 3 units then right a single unit.

Therefore, another point could be (1,-4).

With our two points, we can create our graph by creating a straight line through those two points and therefore plotting our line.

Cheers!

Answer:

Step-by-step explanation:

y = 3x - 7 is a linear equation with y-intercept -7 (or    (0, -7)   ) and slope 3.  These two quantities are instantly readable from the equation.

There are several ways in which we may graph this equation.  One is to plot the y-intercept (0, -7)  Then choose an x-value, such as 3, and evaluate the function at that x value.  We see that y = 9 - 7, or y = 2, when x = 3. Then another point on the graph besides (0, -7) is (3, 2).  Plot (3, 2) and then draw a line through the two plotted points.

Here's another way:

The slope here is 3, or 3/1, which represents rise / run.  Plot (0, -7) as before.

Move your pencil from (0, -7) 1 space to the right and 7 spaces up.  Then plot a new point at that location.  Draw a line through (0, -7) and (1, 0).
