Answer:
D. Infinite solutions.
Step-by-step explanation:
Since they give us the equation for (y) we just implement that equation in place of (y) in the second equation
15x+3y=27 now becomes
15x+3(-5x+9)=27
Distribute the 3
15x-15x+27=27
15x and -15x cancel out
27=27
Infinite solutions since both sides are exactly equal.

Answer:
Given that,
In right triangle ABC, C is the right angle.
sin A=0.4
To find cos B,
we get the triangle as,
we know that,
Hypotenuse of the triangle is AB
For the angle A, opposite side is CB
For the angle B, adjacent side is CB
From the definition of sine and cosine we get,
Also,
Comparing both we get,
It is given that sinA=0.4
Hence we get, cosB=0.4
Answer is: 0.4
Answer:
(x+1)(x+10)
Step-by-step explanation:
You must find two numbers that multiply to make 10 and add to make 11. In this case those numbers are 1 and 10 (1×10=10, 1+10=11)
