Answer:

h> 7

Step-by-step explanation:

you want to solve for h

to do so you need to divide both sides by -9

divideing by a negative swaps the sign < becomes >

h > -63/-9

Answer:

5 miles towards north

Step-by-step explanation:

Given that:

Desiree drove towards north.

Time for which Desiree drove north = 30 minutes

Speed while driving north = 50 miles per hour.

Then Desiree drove towards south.

Time for which Desiree drove south = 60 minutes

Speed while driving south = 20 miles per hour.

To find:

The distance and the direction in which Desiree is now from where she has started?

Solution:

Formula for distance traveled can be given as:

[tex]Distance = Speed \times Time[/tex]

Let us convert the given time in hours first.

While traveling north, time = 30 minutes = [tex]\frac{1}2[/tex] hours

Distance traveled towards north = 50 [tex]\times[/tex] [tex]\frac{1}2[/tex] = 25 miles

Then she started traveling south i.e. in the direction just opposite to earlier direction.

While traveling south, time = 60 minutes = 1 hour

Distance traveled towards south = 20 [tex]\times[/tex] 1  = 20 miles

So, the distance at which she is from the starting point = 25 miles towards north - 20 miles towards south = 5 miles towards north

Answer:

y = 9x - 5

Step-by-step explanation:

The slope is already given, so we just need to find the y-intercept.

Plug in 9 for m, 1 for x, and 4 for y in the equation y = mx + b.

4 = 9(1) + b

b = -5

Now that we know the y-intercept, we can construct the equation of the line.

y = 9x - 5

Step-by-step explanation:

Option B is correct as the y-intercept is 6.

Answer:

The exact value of sin A is opp/hyp = -12/13

Step-by-step explanation:

If A is in Quadrant IV then the "opposite side" is negative and the "adjacent side" is positive.  Since sec A = hyp / adj = 13 / 5 and since opp^2 + adj^2 must add up to hyp^2,   Therefore y = √(hyp^2 - adj^2), or

y = -√(13^2 - 25) = -√144 = 12.

The exact value of sin A is opp/hyp = -12/13

Answer:

y = 3x - 6

Step-by-step explanation:

The slopes of perpendicular lines are negative reciprocals. In other words, if you know one slope, flip it and change the sign to find the other slope.

slope f given line: -1/3

flip it to get -3/1 which is the same as -3.

Change the sign to get 3.

The perpendicular line has slope 3.

y = mx + b

y = 3x + b

Use point (5, 9) for x and y and solve for b.

9 = 3(5) + b

9 = 15 + b

b = -6

y = 3x - 6

Answer:

Because if it's proportional it will be on the origin

Answer:

-[tex]\frac{5}{7}[/tex]

Step-by-step explanation:

Slope = [tex]\frac{rise}{run}[/tex]

          = [tex]\frac{6-11}{5-(-2)}[/tex]

          = [tex]\frac{6-11}{5+2}[/tex]

          = [tex]\frac{-5}{7}[/tex]

          = -[tex]\frac{5}{7}[/tex]

Answer:

To calculate the slope, you can first substract the points to get the vector that join both, you may do it like this:

(-2, 11) - (5,6) = (-2 - 5, 11 - 6) = (-7, 5)

To get the slope when you get the vector (x,y), you will have to divide y be x:

5/-7

So the slope is 5/-7, [tex]-\frac{5}{7}[/tex]

Answer:

400 cupcakes

Step-by-step explanation:

So, 340 is 85%. 15% is chocolate.

340/x = 85/100

34000=85x

x=400

Total = 400 cupcakes.

Hope this helps!

Answer:

shade in 6 pieces

Step-by-step explanation:

Answer:

$57,600

Step-by-step explanation:

first: 20% of 40,000 = 8,000

second: add 40,000 + 8,000 = 48,000

third: 20% of 48,000 = 9,600

fourth: add 9,600 + 48,000 = 57,600

which is your answer

Answer: =28n+7

Step-by-step explanation:

Answer:

           d=7

Step-by-step explanation:

it is arithmetic sequence

so we will use this equation to get d (common difference)

a(n) = a1 +(n-1)d

we have the tenth term=67  and a1 =4

then

a(10) = 4 +(10-1)d=67

          4+10d-1d=67

          9d=67-4

          9d=63 dividing by 9

           d=7

hope this helps

Answer:

The had 8 drinks

Step-by-step explanation:

Here, we want to calculate the number of drinks they had

Let the total number of drinks be x

And the number of drinks they had be y

From the first part, we have that;

x-3(y) = 3

x -3y = 3

x = 3 + 3y •••••••(i)

Secondly

x-2(y) = 11

x = 11 + 2y •••••(ii)

We equate the two x

11 + 2y = 3y + 3

3y-2y = 11-3

y = 8

So what this mean is that they had 8 drinks

Answer:

the slope is 10 so false

Step-by-step explanation:

Answer:

FALSE

Step-by-step explanation:

This is slope-intercept form: y=mx+b

The m is the slope and here the m=10, so the slope is 10, not 6.
