A dfc is equal to bfc and that is a fact
Answer: negative
Step-by-step explanation:
With yx = zx, then by the Multiplicative Property of Equality, y = z. Since z is a negative integer, then y is also a negative integer. Since yx is positive, with y equal to a negative integer, then x is negative.
Answer:
96
Step-by-step explanation:
A=Area
Using the formulas
![A= 2A_{b} +(a+b+c)h\\A_{b} = \sqrt{s(s-8)(s-10)(s-6)} \\s= \frac{8+10+6}{2}](https://tex.z-dn.net/?f=A%3D%202A_%7Bb%7D%20%2B%28a%2Bb%2Bc%29h%5C%5CA_%7Bb%7D%20%3D%20%5Csqrt%7Bs%28s-8%29%28s-10%29%28s-6%29%7D%20%5C%5Cs%3D%20%5Cfrac%7B8%2B10%2B6%7D%7B2%7D)
Solving for A
![A=ah+bh+ch+\frac{1}{2}*\sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}](https://tex.z-dn.net/?f=A%3Dah%2Bbh%2Bch%2B%5Cfrac%7B1%7D%7B2%7D%2A%5Csqrt%7B-a%5E4%2B2%28ab%29%5E2%2B2%28ac%29%5E2-b%5E4%2B2%28bc%29%5E2-c%5E4%7D)
![A=8(2)+10(2)+6(2)+\frac{1}{2}*\sqrt{-8^{4} +2*(8*10)^{2} +2*(8*6)^{2}-10^{4} +2*(10*6)^{2}-6^{4} }](https://tex.z-dn.net/?f=A%3D8%282%29%2B10%282%29%2B6%282%29%2B%5Cfrac%7B1%7D%7B2%7D%2A%5Csqrt%7B-8%5E%7B4%7D%20%2B2%2A%288%2A10%29%5E%7B2%7D%20%2B2%2A%288%2A6%29%5E%7B2%7D-10%5E%7B4%7D%20%2B2%2A%2810%2A6%29%5E%7B2%7D-6%5E%7B4%7D%20%7D)
![A=96](https://tex.z-dn.net/?f=A%3D96)
Y= 1x+ 3
1x is the slope and 3 is the y intercept
I did rise over run to find the slope 3/3=1
Y is 3 because y intercept is when a line go through the y axis and it’s on 3
hope this helps!
A) Vertical angles are congruent: It is true. Vertical angles are called opposite angles, so they are congruent.
B) Angles with measures between 0- 90 degrees are complementary: It is false. Complementary angles are angles that the sum of their value is 90°
C) Straight angles are complementary: it is false. Straight angles are angles which value is 180°.
D) Angles with measure between 90 and 180 degrees are obtuse. This statement is true by definition
