X represents the number of books you have. If you say to a friend "I have more than 25 books" then you can write "x > 25" which says "x is greater than 25"

Something like x = 50 will make x > 25 since 50 is larger than 25. In contrast, a value like x = 20 is going to make x > 25 false because 20 > 25 is false (20 is smaller than 25, not larger)

Solve and show your work please!x+7=2(3x-4)

Brrunno [24]

x + 7 = 2(3x - 4) Remove the brackets

x + 7 = 2*3x - 4*2

x + 7 = 6x - 8 Subtract 7 from both sides.

x + 7 - 7 = 6x - 8 - 7

x = 6x - 15 Subtract 6x from both sides

x - 6x = - 15

-5x = - 15 Divide by -5

-5x/-5 = -15/-5

x = 3

I am going to guess you want to find a line which passes through the points (0,4) and (2,10)...

y₂-y₁ / x₂-x₁
10 - 4 / 2 - 0
6 / 2
3....slope
(0,4) .....b

y = 3x + 4

3. A kite is aloft at the end of a 1500 foot string. The string make an angle of 43° with the

sineoko [7]

Answer:

$h= 1500\,*\,sin(43^o)$

Step-by-step explanation:

Notice that there is a right angle triangle formed with sides as follows:

hypotenuse is the actual 1500 ft string. The acute angle 43 degrees is opposite to the segment that represents the height of the kite from the ground. Therefore, the trigonometric ratio that we can use to find that opposite side to the given angle, is the sine function as shown below:

$sin(43^o) = \frac{opposite}{hypotenuse} \\sin(43^o) = \frac{opposite}{1500}\\opposite = 1500\,*\,sin(43^o)\\h= 1500\,*\,sin(43^o)$
