Answer:

y=-2x-3

Step-by-step explanation:

Since the slope is -2, we can make an equation : y=-2x+b

Now plug in the point given to find b.

1=-2(-2)+b

1=4+b

b=-3

so, the equation is y=-2x-3

A ball is tossed between three friends. The first toss is 8.6 feet, the second is 5.8 feet, and the third toss is 7.5 feet, whic

Answer:

The angles are 79.45, 59.02 and 41.53 degrees to the nearest hundredth.

Step-by-step explanation:

We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.

Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:

cos X = (8.6^2 - 5.8^2 - 7.5^2) / ( -2*5.8*7.5)

= 0.18310

X = 79.45 degrees.

We can now find another angle using the sine rule:

8.6 / sin 79.45 = 7.5/ sin Y

sin Y = (7.5 * sin 79.45) / 8.6

Y = 59.02 degrees

So the third angle = 180 - 79.45 - 59.02

= 41.53 degrees.

Simon must maintain an average grade of 80% or better in his math class to be eligible to play sports.His math grade so far are

Sophie [7]

Answer:

Let x be the percentage score he got in fifth test,

According to the question,

His score in first, second, third and fourth test are 80%, 84%, 76% and 77% respectively,

Thus, the average of his total score in the five test,

= $\frac{80+84+76+77+x}{5}$

But, Again according to the question,

The average of the five grades as greater than or equal to 80%

That is,

$\frac{80+84+76+77+x}{5}\geq 80$

⇒ $\frac{317+x}{5}\geq 80$

⇒ $317 + x \geq 400$

⇒ $x\geq 83$

Thus, the least score he can get in the fifth test is 83.
