<h3>Answer: Choice 2) sin(B) = cos(90-B)</h3>

Explanation:

The rule is that

sin(A) = cos(B)

if and only if A+B = 90.

Solving for A gets A = 90-B

So we end up with

sin(90-B) = cos(B)

which is the same as

cos(B) = sin(90-B)

4x-5y=-15 <br> 7x-2y=21 <br> X=<br> Y=

Helen [10]

Answer:

The values of x and y to the given equations are x=5 and y=7

Step-by-step explanation:

Given equations are $4x-5y=-15\hfill (1)$

$7x-2y=21\hfill (2)$

To solve the given equations by elimination method :

Multiply the equation (1) into 2 we get

$8x-10y=-30\hfill (3)$

Multiply the equation (2) into 5 we get

$35x-10y=105\hfill (4)$

Now subtracting the equations (3) and (4) we get

$8x-10y=-30$

$35x-10y=105$

_________________

$-27x=-135$

$x=\frac{135}{27}$

Therefore x=5

Now substitute the value of x=5 in equation (1) we get

4(5)-5y=-15

20-5y=-15

-5y=-15-20

-5y=-35

$y=\frac{35}{5}$

Therefore y=7

The values are x=5 and y=7

F(x)x^2-2x and g(x)=6x+4 for which value of x does (f+g)(x)=0

Papessa [141]

Answer:

(f+g)(x)

Step-by-step explanation:

(f+g)(x)=

${x}^{2} - 2x + 6x + 4 = {x}^{2} + 4x + 4$

$(x + 2)(x + 2) = 0$

$(x + 2) = 0 \\ x = - 2$
