Answer: SECOND OPTION

Step-by-step explanation:

You must find the ratio of the sides of the triangle, as following:

r=\frac{30}{42}=\frac{5}{7}

Therefore, the ratio of the areas is:

r_A=(\frac{5}{7})^{2}\\\\r_A=\frac{25}{49}

Now you must multiply the area of the larger triangle by the ratio obtained above, therefore, you have that the result is:

A_s=(382ft^{2})(\frac{25}{49})=194.89ft^{2}≈195ft^{2}

Explain why a graph that fails the vertical-line test does not represent a function. Be sure to use the definition of a function
ArbitrLikvidat [17]

Explanation:

A function is a relationship where any one x-value/input only has <u>one </u>corresponding y-value/output. (note: a y-value can have multiple x-values).

> This can be called "assigning one y-value to every x element".

The vertical line test places a line that would connect all y-values of an x-value (that is, if it were to have multiple y-values). If multiple points can be found along the vertical line, it is, therefore, by the definition of a function, not a function. (Because an x-value will have more than one y-value).

So, a graph that fails the vertical-line test does not represent a function because an x-value will correspond with more than one y-value.

hope this helps!!

What is the solution to the system of equations below? -4x+6y=-18 and y=-2x+21
Verdich [7]

Answer:

x=9 and y=3

Step-by-step explanation:

Let's solve your system by substitution.

−4x+6y=−18 and y=−2x+21

Rewrite equations:

y=−2x+21;−4x+6y=−18

Step: Solve  y=−2x+21for y:

y=−2x+21

Step: Substitute−2x+21foryin−4x+6y=−18:

−4x+6y=−18

−4x+6(−2x+21)=−18

−16x+126=−18(Simplify both sides of the equation)

−16x+126+−126=−18+−126(Add -126 to both sides)

−16x=−144

−16x

−16

=

−144

−16

(Divide both sides by -16)

x=9

Step: Substitute9forxiny=−2x+21:

y=−2x+21

y=(−2)(9)+21

y=3(Simplify both sides of the equation)

Answer:

x=9 and y=3

The hocky team won 63 out of 84 games what percent of the games did the team win?​
Ronch [10]

Answer:

75%

Step-by-step explanation:

To find how much percent of the team won, you have the event over the sample space.

So n(E)/n(S) = 63/84 = 3/4 = 0.75 = 75%

Feel free to comment if you have any questions! :D
