help me please???????​

Answer:

<A = 76°

<B = 63°

<C = 41°

Plug in the value of x

<C = 34 + 7

<C = 41°

Step-by-step explanation:

[tex] 63 + (2x + 8) + (x + 7) = 180 [/tex] (sum of ∆)

Solve for x

[tex] 63 + 2x + 8 + x + 7 = 180 [/tex]

Add like terms

[tex] 78 + 3x = 180 [/tex]

Subtract 78 from each side

[tex] 78 + 3x - 78 = 180 - 78 [/tex]

[tex] 3x = 102 [/tex]

Divide both sides by 3

x = 34

<A = 2x + 8

Plug in the value of x

<A = 2(34) + 8 = 76°

<B = 63°

<C = x + 7

Plug in the value of x

<C = 34 + 7

<C = 41°

Answer:

Step-by-step explanation:

Simplifying

x2 + -9 = 0

Reorder the terms:

-9 + x2 = 0

Solving

-9 + x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9' to each side of the equation.

-9 + 9 + x2 = 0 + 9

Combine like terms: -9 + 9 = 0

0 + x2 = 0 + 9

x2 = 0 + 9

Combine like terms: 0 + 9 = 9

x2 = 9

Simplifying

x2 = 9

Take the square root of each side:

x = {-3, 3}

Answer:

3.) [tex]y = \frac{2}{5} x - 7.2[/tex]

4.) [tex]y = -3x - 1[/tex]

Step-by-step explanation:

You have to find the y-intercept in both questions to put it in point-slope form. The first step is to substitute y and x from the question into point slope-form. You get -6 = m(-3) + b. Then you substitute for the slope which is 2/5. You end up with -6 = [tex]\frac{2}{5}[/tex] (-3) + b. Solve for b which is -7.2 and put the slope and y-intercept into the final point-slope equation. You follow the same steps for question 4.

Answer:

[tex]y-1=\frac{1}{8}\left(x-7\right)[/tex] is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Step-by-step explanation:

The endpoints:

Calculating the Midpoint M of BC:

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]

The Midpoint M of BC [tex]=\left(\frac{8+6}{2},\:\frac{-7+9}{2}\right)[/tex]

                                     [tex]=\left(7,\:1\right)[/tex]

Calculating the slope of BC:

[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)[/tex]

[tex]m=\frac{-7-9}{8-6}[/tex]

[tex]m=-8[/tex]

Given a line with slope [tex]m[/tex] then the slope of a

line  perpendicular to it is:

[tex]m_{prependicular}=-\frac{1}{m}=-\frac{1}{-8}=\frac{1}{8}[/tex]

Equation of line using point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-1=\frac{1}{8}\left(x-7\right)[/tex]        

Therefore, [tex]y-1=\frac{1}{8}\left(x-7\right)[/tex] is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Answer:

1/8

Step-by-step explanation:

First, take 3/4 and make a common denominator with 3/8. You can make 3/4 into 6/8. Now, subtract 3/8 from 6/8 which is 3/8.

Second, find the common denominator between 3/8 and 1/2. You can make 1/2 into 4/8.

Third. Now subtract 3/8 from 4/8. You get 1/8.

The answer therefore is 1/8

In Sevilla in the year 1842, you are Miguel Cervantes de Navas y Colon, a captain in the Royal Spanish Army. The total number of cannonballs in the stack is 385.

Given that,

In Sevilla in the year 1842, you are Miguel Cervantes de Navas y Colon, a captain in the Royal Spanish Army.

A pile of cannonballs is seen outside the window of your barracks.

​The total number of cannonballs can be calculated using the steps below:

The following is a general formula to determine how many cannonballs are altogether in the stack:

Total number of cannonballs is n(n+1)(2n+1)/6

where "n" represents the overall number of layers.

Change the value of "n" in the formula above.

1st layer is stack of cannonballs is 1²=1 cannonball.

2nd layer is stack of cannonballs is 2²=4 cannonballs.

3rd layer is stack of cannonballs is 3²=9 cannonballs.

last layer is stack of cannonballs is 10²=100 cannonballs.

n is 10.

Substitute in the formula

=10(10+1)(2×10+1)/6

=10×11×21/6

=385

Therefore, the total number of cannonballs in the stack is 385.

Answer:

-43K+17

Step-by-step explanation:

(–9k3 + 12k2 + 9) – (10k3 + 3k2 + 4k – 8)

-9.3=-27                        10.3=30

Answer:

-19k³ + 9k² + 17

Step-by-step explanation:

Given expression;

         (-9k³ + 12k² + 9)  - (10k³ + 3k² + 4k - 8)

To simplify, expand the brackets.

In the second bracket, the negative sign multiplies through;

   = (-9k³ + 12k² + 9)  - 10k³ - 3k² - 4k + 8

     = -9k³ + 12k² + 9 - 10k³ - 3k² - 4k + 8

     = -9k³ - 10k³  + 12k² - 3k²+ 9+ 8

     = -19k³ + 9k² + 17

Answer:

(a) x + 3(x + 4) = 5(x + 2) - 5

(b) youngest: 7 years old

middle: 9 years old

oldest: 11 years old

Step-by-step explanation:

(a)

We know that x is the youngest child's age. Since the sisters' ages are consecutive odd integers, we know that the ages differ by 2. So, the middle sister's age is x + 2 and the oldest sister's age is x + 4.

Our equation to model the sentence "the sum of the age of the youngest and three times the age of the oldest is five less than five times the middle sister's age" would be:

x + 3 * (x + 4) = 5 * (x + 2) - 5

x + 3(x + 4) = 5(x + 2) - 5

(b)

Now, we can just solve the equation above:

x + 3(x + 4) = 5(x + 2) - 5

x + 3x + 12 = 5x + 10 - 5

4x + 12 = 5x + 5

x = 12 - 5 = 7

So, the youngest sister is 7 years old.

That means the middle sister is 7 + 2 = 9 years old, and the oldest sister is 9 + 2 = 11 years old.

The ages, then, are:

youngest: 7 years old

middle: 9 years old

oldest: 11 years old

Answer:436

Step-by-step explanation:

Since Colin scored 141 and Brian scored 154 more than Colin that would be (154+141). So Brian scored 295, so you add Brian's score and Colin's so 295+141, the total score is 436

Answer:

When you substitute 0 for the exponent x, the expression simplifies to a times 1, which is just a. This is because any number to the 0 power equals 1. Since the initial value is the value of the function for an input of 0, the initial value for any function of this form will always be the value of a
