Answer:
Two points on the line are (0, -6) and (1, -3)
Step-by-step explanation:
I have a graphing calculator
The answer is
the first one is x= 18.98
a^2+b^2=c^2
8 cm^2+17 cm^2= x^2
64+289=x^2
√x^2= √353
x=18.89
<span><span>the second one is x= 18.7
a^2+b^2=c^2
7 m^2+ x^2= 20 m^2
49 m+x^2=400 m
-49 -49
</span></span>√x^2=√352
<span><span>x= 18.7
Hope this helps!</span></span>
Answer:
see explanation
Step-by-step explanation:
Given a quadratic equation in standard form, ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant Δ = b² - 4ac informs us about the nature of the roots.
• If b² - 4ac > 0 then 2 real and distinct roots ( solutions )
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then roots are not real
Given
3x² - 6 = 2x ( subtract 2x from both sides )
3x² - 2x - 6 = 0 ← in standard form
with a = 3, b = - 2, c = - 6 , thus
b² - 4ac = (- 2)² - ( 4 × 3 × - 6) = 4 - (- 72) = 4 + 72 = 76
Since b² - 4ac > 0 then the solution is 2 real and distinct roots
Answer:
51
Step-by-step explanation:
4x12-3x3+12
48-9+12=51
we can think of this as the same as a deposit in a bank, so let's use the compound interest formula, since the book is increasing in value 12% per annum.
