x = the first number
(x/2)² = 14
Hope this helps!
Can I get brainliest? thanks.
The solution to the system is (-2,-8)
Answer:
From the given graph , The equation y = x² - 3 x has x-intercept of 3 , 0
Step-by-step explanation:
Given as :
Let The standard equation of line
y = m x + c
where m is the slope of line and c is y-intercept
For, x-intercept , put y = 0
For y-intercept , put x = 0
A) y = x + 3
for x-intercept , y = 0
So, 0 = x + 3
i.e x = - 3
B) y = x² + 3 x
for x-intercept , y = 0
So, 0 = x² + 3 x
i.e 0 = x² + 3 x
Or, x ( x + 3) = 0
Or, x = 0 , x = - 3
C) y = x² - 3 x
for x-intercept , y = 0
So, 0 = x² - 3 x
i.e 0 = x² - 3 x
Or, x ( x - 3) = 0
Or, x = 0 , x = 3
D) x = y² - 3 y
for x-intercept , y = 0
So, x = 0 - 0
i.e x = 0
Hence, From the given graph , The equation y = x² - 3 x has x-intercept of 3 , 0 Answer
Answer:
9.75 feet
Step-by-step explanation:
You use the pythagorean theorem to solve. A is the unknown, while b is 7 feet, and c is 12 feet
A^2 + 7^2 = 12^2
A^2 + 49 = 144
Subtract 49 from both sides to get
A^2 = 95
then take the square root of both sides to get
A (the height) = 9.74679434481
I usually round to 2 decimal points to get the answer 9.75 feet.
