6 0

Answer:

No solution

Step-by-step explanation:

Replace occurrences of y in 4x - 2y = 14 with 2x - 6

y = 2x - 6

4x - 2 (2x - 6) = 14

Simplify left side

y = 2x - 6

12 = 14

Since 12 is not equals to 14, There is no solution

What are the values of a and b? (500 + ax)(50 - bx) pls hurry

gregori [183]

Answer:

Step-by-step explanation:

Perform the indicated multiplication first:

25000 - 500bx + 50ax - abx²

It would seem that this should be part of an equation, and that the other part is missing; without another part, there's no way to determine the values of a and b. Please ensure you have copied this problem down completely.

Angles θ and φ are angles in standard position such that:

BartSMP [9]

When $\theta$ terminates in quadrant III, both $\cos\theta$ and $\sin\theta$ are negative, and

$\sin^2\theta+\cos^2\theta=1\implies\cos\theta=-\sqrt{1-\sin^2\theta}=-\dfrac{12}{13}$

When $\varphi$ terminates in quadrant II, $\cos\varphi$ is negative and $\sin\varphi$ is positive, so

$1+\tan^2\varphi=\sec^2\varphi\implies\sec\varphi=-\dfrac{17}{15}$

which gives

$\cos\varphi=\dfrac1{-\frac{17}{15}}=-\dfrac{15}{17}$

$\tan\varphi=\dfrac{\sin\varphi}{\cos\varphi}=-\dfrac8{15}\implies\sin\varphi=\dfrac8{17}$

Now,

$\sin(\theta+\varphi)=\sin\theta\cos\varphi+\cos\theta\sin\varphi=-\dfrac{21}{221}$
