The base of a 14-foot ladder is 5 feet from a building, If the ladder reaches the flat roof, how tall is the building?

Answer:

[tex]15 - 10c = 13 \\ 10c = 15 - 13 \\ 10c = 2 \\ c = \frac{2}{10} \\ c = \frac{1}{5} [/tex]

Answer:

x+y>=3

Step-by-step explanation:

values of x and y are all greater than or equal to 3

Answer:

3 times - 2,times 8-13

You solve the ones in the bracket first

(the rule of BODMAS)

So 8-13 first, then

-2times 8-13,then

Then you get your answer

Answer:

100

Step-by-step explanation:

Because Jasmine plus 9 friends equal to 10. And each person gives away 10 free samples. 10 times 10 equals to 100. Hope it helps and I’m so sorry if I’m wrong.

Answer:

Its 100

Step-by-step explanation:

because 10x10 equals 100 (PLUS JASMINE) you have to add jasmine or else it would be incorrect.

Answer:

-5 x -5 = 25

7 x 5 = 28

53 + 2 = 55

D. 55

There it is my dear friend.

Answer:

28 words.

Step-by-step explanation:

You already know that he types at a rate of 14 words per minute.

To find how many words he types in 2 minutes, just multiply 14 by 2.

You get 28, which tells you how many words Reuben can type in 2 minutes.

Answer :

The answer is 28.

Answer:

20 units

Step-by-step explanation:

to solve this equation you need the pythagorean theorem: a^2 + b^2 = c^2

2^2 + 7^2 = 53; square root of 53 is 7.28010989; or about 7.3 units (line AC)

2^2 + 6^2 = 40; square root of 40 is 6.32455532; or about 6.3 units (line BC)

4^2 + 5^2 = 41; square root of 41 is 6.40312424; or about 6.4 units (line AB)

7.3 + 6.3 + 6.4 = 20

20 units

C.) [tex]e^3r^3t^3[/tex]

Step-by-step explanation:

The least common multiple (LCM) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.

The required equation is D = 5n + 200 and the amount deposited after 8 months is $240

Given the amount that steven deposited every month as $200

Let n be the number of months

D = 200 + 5n = 5n + 200

In order to get the amount deposited after 8 months, we will replace n by 8 to have:

D = 200 + 5(n)

D = 200 + 5(8)

D = 200 + 40

D = 240

Hence the required equation is D = 5n + 200 and the amount deposited after 8 months is $240

How to calculate axis of symmetry:

Plug your numbers into the axis of symmetry formula. To calculate the axis of symmetry for a 2nd order polynomial in the form ax 2 + bx +c (a parabola), use the basic formula x = -b / 2a. In the example above, a = 2 b = 3, and c = -1. Insert these values into your formula, and you will get:

How to calculate vertex:

The vertex form of a quadratic is given by

y = a(x – h)2 + k, where (h, k) is the vertex.

The "a" in the vertex form is the same "a" as

in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down. Think of it this way: A positive "a" draws a smiley, and a negative "a" draws a frowny. (Yes, it's a silly picture to have in your head, but it makes is very easy to remember how the leading coefficient works.)

In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.

Suppose that "a" is positive, so a(x – h)2 is zero or positive and, whatever x-value you choose, you're always taking k and adding a(x – h)2 to it. That is, the smallest value y can be is just k; otherwise y will equal k plus something positive. When does y equal only k? When x – h, the squared part, is zero; in other words, when x = h. So the lowest value that y can have, y = k, will only happen if x = h. And the lowest point on a positive quadratic is of course the vertex.

If, on the other hand, you suppose that "a" is negative, the exact same reasoning holds, except that you're always taking k and subtracting the squared part from it, so the highest value y can achieve is y = k at x = h. And the highest point on a negative quadratic is of course the vertex.

Answer:

[tex]x=1[/tex]

Step-by-step explanation:

Because vertical angles are always equal, we want to solve [tex]50x+10=70x-10[/tex].

We can add 10 to both sides to get [tex]50x+20=70x[/tex].

We can subtract [tex]50x[/tex] from both sides to get [tex]20=20x[/tex].

Lastly, we divide both sides by 20 to get [tex]1=x[/tex].

So, [tex]\boxed{x=1}[/tex] and we're done!

The check is left as an exercise to the reader.

Answer:

x= 1

Step-by-step explanation:

TO solve you can use the equation 50x+10=70x-10.

First, subtract 10 from both sides:

50x= 70x-20

Then subtract 70x from both sides:

-20x=-20

Then divide by -20:

x=1

Check your work:

50(1)+10=70(1)-10

50+10=70-10

60=60

Answer:

You work for x hours and earn $20 for each hour. You get paid $60 before you come in each day. What is y when you work for x hours?

Step-by-step explanation:

x is the independent variable and can vary. You have to add the $60 in there, too. Adding them together gets you to y = 20x + 60 and this real life scenario works.

Step-by-step explanation:

You didn't show the triangle, but we suppose the coordinate of B is (x,y)

when it reflect over the line x=-1, (x , y) - > (- (x - (-1)) , y) ==>  (- (x+1) , y)

then translate (x+2,y-5) : (-(x+1) , y) -> - (-(x+1)+2 , y-5) ==>  (-x+1 , y-5)

such as (5,3) -> (-6,3) -> (-4 , -2)
