Point slope formula is y= mx+b. To find the slope, or m, you need to find the "rise over run". rise = y coordinates, run = x coordinates. And the slope equation is y1-y2/x1-x2. So let's say the first point is (x1,y1) and the second is (x2,y2). that would be 35-(-31)/5-(-6)= 66/11 or 6/1 aka up six, across one. That is your slope. So far you have y=6x+b, next plug (5,35) into that equation and solve for b (aka the y intercept). So: 35=6(5)+b. 35-30=b, b=5. So your final equation is y=6x+5.

5) Naomi is sewing some clothing. She has 53 yards of fabric to use. She

EleoNora [17]

The inequality that represents the number of each type of fabric that Naomi has is:

$9x+16y \leq 53$

Let the number of short-sleeved shirts she made be x

Let the number of long-sleeved shirts she made be y

Length of clothes used to make a short-sleeved shirt = 9 yards

Length of clothes used to make a long-sleeved shirt = 16 yards

Length of short-sleeved shirts made = 9x

Length of long-sleeved shirts made = 16y

Total length of fabric used = 53 yards

The inequality that represents the number of each type of fabric that Naomi has is:

$9x+16y \leq 53$

Mr. Bennet owns 4 restaurants. The mean number of tables is 30. What could happen to the mean if he buys two new restaurants, on

wariber [46]

Answer:

Final mean value = 24.

Mean value decreased by 6 finally.

Step-by-step explanation:

Total number of restaurant initially = 4

Mean number of tables in restaurants = 30

So, total number of tables in restaurants = 4×30 = 120

Now,

He buys 2 new restaurants with 15 tables and 9 tables .

So, final number of tables = 120 + 15 + 9 = 144.

And, final number of restaurants = 4 initially + 2 newly added = 6 restaurants.

Thus , final mean value of tables in restaurants = $\frac{144}{6}$ = 24.

Thus , mean value decreased by 6 finally

I need help quick, its super hard

faltersainse [42]

Answer:

Q

Step-by-step explanation:

The nearest perfect square of sqrt10 is sqrt9 and sqrt 16, representing a 3 and 4.

Thus, we can conclude that sqrt10 is between 3 and 4.

Notice sqrt 10 is very close with sqrt9 than sqrt16, it should be closer to 3 rather than 4.

The only point that fits the context is Q

If sin theta is negative and cot theta is positive, in which quadrant does theta terminate?

krok68 [10]

All you need to know is that:

In the first quadrant, both coordinates are positive
In the second quadrant, x is negative and y is positive
In the third quadrant, both coordinates are negative
In the fourth quadrant, x is positive and y is negative
The sine is the y coordinate of the points on the unit circle
The cosine is the x coordinate of the points on the unit circle
The cotangent function is defined as the ration between the cosine and the sine of an angle.

So, if sin theta is negative and cot theta is positive, you're saying that you're looking at a point with negative y coordinate and such that

$\dfrac{\cos(\theta)}{\sin(\theta)}>0$

The ratio of two numbers is positive if and only if they have the same sign, so the cosine must by negative as well.

Saying that an angle has negative sine and cosine is the same as saying that the angle identifies a point on the unit circle where both x and y coordinates are negative.

So, if you look at the bullet list at the beginning, you'll see that the point is in the third quadrant.
