Answer:

Step-by-step explanation:

Simplified expression:

3x^3 -x^3 +5x^3-9x^3

2x^3 +5x^3-9x^3

7x^3 -9x^3

-2x^3

If x = -1, the value of the expression is:

-2x^3

-2(-1^3)

-2(-1)

2

Hope this helps!

1. What is the area of the triangle below?<br> 10 in.<br> 7 in.
Alex787 [66]

Hi

<u>The area of a triangle is </u>

\cfrac{base*height}{2}

If we plug in the given values, we get:

\frac{10*7}{2}

Multiply in the numerator:

\frac{70}{2}

Divide:

35

Therefore, the area of the triangle is 35 inches squared.

lord [1]
This can be factored into (x+9)(x+5)/(x+9)(x+1)
once simplified, it's (x+5)/(x+1)
The denominator cannot be negative, so x≠-1

Therefore, the answer is C.

What is the experamental probability that the coin lands on heads?
sammy [17]

Answer:

The experamental probability that the coin lands on head is 50 %

Step-by-step explanation:

Given:

Experiment:

A coin is Toss

Let the Sample Space be 'S' that is total number of outcomes for a coin has been tossed = { Head, Tail }

∴ n ( S ) =  2

Let A be the event of getting a Head on tossing a coin i.e  { Head }

∴ n( A ) = 1

Now,

\textrm{Probability} =\frac{\textrm{outcomes for the experiment}}{\textrm{total number of outcomes}}

Substituting the values we get

P(A) = \frac{n(A)}{n(S)} \\\\P(A) = \frac{1}{2} \\\\P(A) = 0.5\\\\P(A) = 50\%

The experamental probability that the coin lands on head is 50 %

Write an equation of the line in slope-intercept form.<br><br><br><br> The equation is y= <br> .
aivan3 [116]

Answer:

y = x + 2

Step-by-step explanation:

     Slope-intercept form is y = mx + b where m is the slope and b is the y-intercept. Here, b is equal to 2 because the line crosses the y-axis at 2. THe slope is rise over run, or the change in y divided by the change in x. From the two points given, we get 3/3 which is equal to 1. 1x equals x, so this gives us "no slope." Putting it together gives us y = x + 2.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
