Short side is about 3 1/2 squares so 3 1/2 feet
long side is 7 squares so 7 feet
perimeter = 7 + 7 + 3 1/2 + 3 1/2 = 21 feet
x² + 7x/10 = 1/7
x² + 7x/10 - 1/7 = 0
Δ = b² - 4.a.c
Δ = (7/10)² - 4 . 1 . (-1/7)
Δ = 0,48999999999999994 - 4. 1 . (-1/7)
Δ = 1,0614285714285714
Há 2 raízes reais.
x = (-b +- √Δ)/2a
x' = (-(7/10) + √1,0614285714285714)/2.1
x'' = (-(7/10) - √1,0614285714285714)/2.1
x' = 0,3302565561201596 / 2
x'' = -1,7302565561201595 / 2
x' = 0,1651282780600798
x'' = -0,8651282780600797
Rounding
x' = 0,17
x'' = -0,87
Answer:
8
Step-by-step explanation:
The formula for slope-intercept form is y=mx+b, m is the slope, b is the y intercept so you plug in -3 and (0,4) into the formula and you would get,
y=-3x+4
the point has an x and a y the x=0 and y=4
I hope this helped and was correct.
Step-by-step explanation:
x is greater than or equal to 10.
x ≤ 10 and x < 10 options are incorrect, x is not less than 10.
x > 10 is incorrect, x can be greater but x can be equal to 10 as well.
X ≥ 10 is correct. x is greater than or equal to 10.
<u>Key:</u>
> - Greater Than.
< - Less Than.
≥ - Greater Than or Equal to.
≤ - Less Than or Equal to.
