What is the equation of the following line? Be sure to scroll down first to see all answer options. (0,3) (3,0) A. y = -x + 3 B.

qaws [65]

The correct answer is Choice A.

If you plot the points on a graph, you will see that there is a slope of -1 and the y-intercept is (0, 3).

This matches the equation of y = -x + 3 in Choice A.

Using law of cosines, what is angle X to the nearest degree

Monica [59]

Answer:

$X=68\°$

Step-by-step explanation:

we know that

Applying the law of cosines to the triangle of the figure

$yz^2=xy^2+xz^2-2(xy)(xz)cos(X)$

substitute the given values

$9^2=8^2+8^2-2(8)(8)cos(X)$

Solve for X

$81=64+64-128cos(X)$

$81=128-128cos(X)$

$128cos(X)=128-81$

$128cos(X)=47$

$cos(X)=\frac{47}{128}$

using a calculator

$X=cos^{-1}(\frac{47}{128})$

$X=68\°$

suddenly the number of math problems mathletes had to solve increased by 60%! to keep on track the mathletes try to go faster bu

Natali [406]

9514 1404 393

Answer:

28%

Step-by-step explanation:

If x represents the fractional increase in the number of mathletes, and if problem-solving speed is jointly proportional to their speed and their number, we want ...

(1 +25%)(1 +x) = (1 +60%)

1 +x = 1.60/1.25 = 1.28

x = 0.28 = 28%

The team size must increase by 28% to solve all of the problems on time.
