Answer: -20n^2 - 39n - 15

Step-by-step explanation:

first, we remove the parenthesis (multiply everything out).

-20n^2 - 24n - 15 - 15n

then, we simply collect like terms.

-20n^2 - 39n - 15

Answer:

-20n^2-39n-15

Step-by-step explanation:

Given: -4n(5n+6)-5(3+3n)

Use the distributive property: -20n^2-24n-15-15n

Combine like terms: -20n^2-39n-15

Your simplified expression is -20n^2-39n-15

Answer:

1.) slope = 2

2.) slope = [tex]-2\frac{2}{3}[/tex]

3.) slope = [tex]\frac{2}{3}[/tex]

4.) slope = [tex]\frac{1}{4}[/tex]

5.) slope = [tex]1\frac{8}{9}[/tex]

6.) slope = -2

7.) slope = -3

Step-by-step explanation:

In order to find the slope we have to divide they "y" value (the number of units by which the piece of antler goes up) by the "x" value the number of units by which the piece of antler goes to the side). Notice the if the antler moves to the left as it foes up then the "x" value is negative.

Now as I said before we know this......

Let "m" be the slope, then....

[tex]m = \frac{y}{x}[/tex]

So now we just have to plug in the y and x values for each antler and we will get the slopes for each one of them.

1.)

[tex]m = \frac{y}{x}[/tex]

[tex]m= \frac{4}{2}[/tex]

[tex]m = 2[/tex]

2.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{4}{-1.5}[/tex]

[tex]m = -2\frac{2}{3}[/tex]

3.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{2}{3}[/tex]

4.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{1}{4}[/tex]

5.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{8.5}{4.5}[/tex]

[tex]m = 1\frac{8}{9}[/tex]

6.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{2}{-1}[/tex]

[tex]m= -2[/tex]

7.)

[tex]m = \frac{y}{x}[/tex]

[tex]m = \frac{3}{-1}[/tex]

[tex]m = -3[/tex]

Answer:

The relation represented by diagram 4 is NOT a function.

Step-by-step explanation:

To tell if a relation is not a function, pay attention to the x-intercepts. If there is more than one y-intercept with the same x-intercept, then it is not a function, because a function can only have one output (y-value) for each input (x-value).

According to the fourth diagram, the domains include 1, 2, and 3 while the range includes A, B, and C. Also, the ordered pairs would go as follows according to the arrows:

(1, A), (2, A), (2, B), (3, C)

While the y-values, A and B, are different, they share the same input, 2. Therefore, the relation represented by the 4th diagram is NOT a function.

Hope this helps!

Answer:

f^-1 (x)= x/5

Step-by-step explanation:

Answer:

4,1

Step-by-step explanation:

x+y=5 2x-y=7

x=5-y 2(5-y)-y=7

10-2y-y=7

10-3y=7

10-7=3y

3=3y

1=y

substitutes y=1 in x+y=5

x+1=5

x=5-1

x=4

(4,1)

check:

x+y=5

4+1=5

Answer:

The answer will be 40.397.

Step-by-step explanation:

Since the equation of your best fit line is y= 0.404x - 0.003 and they want you to calculate how high the line will be when x=100, plug in 100 in x which will be y= 0.404(100) - 0.003 and you'll get an answer of 40.397.

Answer:

40.397

Step-by-step explanation:

0.404(100)-0.003=40.397

Just plug in the X value for X in the equation and solve. it gives you your answer.

Answer:

7/10ths

Step-by-step explanation:

There are ten blocks all together, which is where the 10 comes from, there is 7 shaded that is where the 7 comes from.

Answer:

The percentage is 70%.

Step-by-step explanation:

There are 10 spaces total, and 7 are shaded in. 7 divided by 10 is 0.7.

0.7 as a percentage is 70%.

So 70% of the block is shaded in.

Answer:

75% increase

Step-by-step explanation:

First we need to figure out how many new records she got this year...

7-4 = 3 new records.

Now, we need to know how many times 4 goes into 100%....

100 ÷ 4 = 25%

This tells us that a single record this year is a 25% increase.

Now, we multiply 25% by 3 to get 75% as our final answer

Answer:

[tex]f(-10)=186[/tex]

Step-by-step explanation:

We can use substitution to find the value of [tex]f(-10)[/tex].

[tex]f(x) = 2x^2+x-4[/tex]

[tex]f(-10) = 2(-10)^2-10-4[/tex]

[tex]=200-10-4[/tex]

[tex]=186[/tex]

∴ [tex]f(-10) =186[/tex]

Hope this helps :)

Answer:

The value of f(-10) is equal to 186.

Step-by-step explanation:

We are given the function:

[tex]f(x) = 2x^2 + x - 4[/tex]

We are told to find the value of:

[tex]f(-10)[/tex]

If we pay close attention, we can see a transition between:

[tex]f(x) \rightarrow f(-10)[/tex]

We have turned x into -10, making x = -10.

Therefore, we can change the value of x in the entire function to -10.

[tex]f(-10)=2(-10)^2+(-10) - 4\\\\f(-10) = 200 - 10 - 4\\\\f(-10) = 186[/tex]

Therefore, f(-10) = 186.

Answer:

The height of the triangle is 5.2 inches

Step-by-step explanation:

we know that An equiangular triangle is a triangle where all three interior angles are equal in measure, so an equiangular triangle is an equilateral triangle. The measures of the interior angle of an equilateral triangle is equal to 60 degrees. Applying the Pythagoras Theorem find out the height of triangle

Answer:

Geometric sequence

.Step-by-step explanation:

Geometric sequences are defined by an initial value and a common ratio . If a sequence does not have a common ratio or a common difference, it is neither an arithmetic nor a geometric sequence. You should still try to figure out the pattern and come up with a formula that describes it.
