This is a bit of a hard, one. So please ask questions.
------
Please use the rule a/b x c/d = ac/bd while solving.
After using that equation, it should look like this:
2 x -5 x -3 / 7 x -8
Simplify 2 x -5 to -10.
Now, it should look like -10 x -3 / 7 x -8
30/7 x -8
30/-56
- 30/56 (the negative is front of the WHOLE equation.)
-15/28 is our final answer.
Answer:
C) cos A=sin B
Step-by-step explanation:
A is complement of B: A+B=90⁰
Sin(A)=sin(90-B)=cos(B)
Cos(A)=cos(90-B)=sin(B)
So c)
Answer:
y+21 = -4(x-7)
Step-by-step explanation:
well first you need to find slope what is y2-y1 over x2-x1
23-(-21) ----> 23+21 = 44
-4 - 7 ---> -4 + -7 = -11
so it 44/-11 = -4 is the slope
now choose one pair of points like 7 , -21 and plug them in
y-y1 = m(slope)(x-x1)
so it be y+21 = -4(x-7)
also remember two negatives = a postitive
Answer: 2.4x−4.4
Step-by-step explanation:
0.3(4x – 8) – 0.5(–2.4x + 4)
1.2x−2.4−0.5(−2.4x+4)
1.2x−2.4−(−1.2x+2)
1.2x−2.4+1.2x−2
(1.2x+1.2x)+(−2.4−2)
2.4x−4.4
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

Reflexive Property=For all real number X,X=X
A number equals itself
Addition Property=For all real number X,y & Z,. if
X=Y then X+y=y+Z
Subtraction Property=For all real number X,Y And Z if X=y then X-Z=y-Z.
