A and E both solve at point (3,6)
For this case we have the following equation:
Applying distributive property to the terms within the parentheses on the left side of the equation we have:
Subtracting "x" on both sides of the equation we have:
Subtracting 4 on both sides of the equation we have:
Answer:
Answer:
Choice B. sin(B)=cos(90-B)
Step-by-step explanation:
That cofunction identity is the one you looking for...choice B.
If you aren't convinced or don't know that identity, then maybe this will help:
90-B is actually the same thing as saying A for this right triangle since A+B=90.
So choice B basically says sin(B)=cos(A)
Well let's find both sin(B) and cos(A)
sin(B)=b/c
cos(A)=b/c
Those are the same ratios!
So they are equal!
X over 2 = -7 comes out to
x
---- = -7. Mult. both sides by 2 to eliminate the fraction:
2
x = 2(-7) = - 14 (answer)
One number is six times as large as a certain smaller number.
i.e., Y = 6x
Answer is 6x
