(9x - 7) - (5x + 10 )
2x - 15x
- 13x
Answer:
Step-by-step explanation:
Use Pythagorean theorem.
Hypotenuse² = base² + altitude²
5) x² = 12² + 6²
= 144 + 36
x² = 180
x = √180
x = 13.42 ft
6) 25² = x² + 19²
625 = x² + 361
625 - 361 = x²
x² = 264
x = √264
x = 16.25 m
7) x² = 7² + 576
= 49 + 576
= 625
x = √625
x = 25 in
8) 2.5² = 2²+ x²
6.25 = 4 + x²
6.25 - 4 = x²
x² = 2.25
x = √2.25
x = 1.5 yd
X=-3 or x=3 Because yo have to reverse the inequality sign
So this is going to be a linear equation, you can tell by seeing the growth being the same between days 15 and 20 & 33 and 38. We will be using the

format, where m = slope and b = y-intercept.
The equation to solve for the slope is

. You can use any two ordered pairs on this list. I'll be using 15 and 20.

45 is the slope.
To solve for the y-intercept, plug in 45 in the m variable and any ordered pair into the x and y variable spot. For this, I'll be using (15, 815)

Now putting the equation together (

) we can plug in 26 into the x variable and solve.
In short, the answer is B. 1,310 feet.
You divide 25 by 5, which is 5
