Answer:

  see attached

Step-by-step explanation:

To plot the line through the point, plot the point. Then find another point that has the given "rise" and "run". Draw the line through the two points.

__

The given point is (-7, -4). Locate that on the graph.

The slope is given as -2/3. This is the ratio of "rise" to "run", so it means the "rise" will be -2 for each "run" of 3. (rise/run = -2/3)

The rise is the vertical change. So, you want your second point to be 2 units below the given point. Its y-coordinate will be -4-2 = -6.

The run is the horizontal change. Your second point will be 3 units to the right of the given point, so its x-coordinate will be -7+3 = -4. Now, you can plot the point (-4, -6) and draw your graph through these two points.

Hi!
Alrighty, so there are 5 sets of 50 in 250 (250 divided by 50), so just take 50 times 12 and get 60! Hope that helped :)

If x - 12y = -210 and x - 6y = 90, then x =
Annette [7]
X=-198(substitute the value of x into the equation)
x-6y=90

-198-6y=90(solve the equation)

y=-48(a possible solution is)

(x,y)=(198,-48). (check yhe solution)

-198-12= 210(simplify)
-198-6(-48)=90

-210=-210( the ordered pair is a solution)
90=90

(x,y)=(198,-48)
is the answer

&lt;B<br>Round your answer to the nearest hundredth.<br>2<br>А<br>3<br>?<br>B​
Svet_ta [14]

Answer:

∠ B ≈ 41.81°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin B = \frac{opposite}{hypotenuse} = \frac{AC}{AB} = \frac{2}{3} , thus

B = sin^{-1}(\frac{2}{3} ) ≈ 41.81° ( to the nearest hundredth )

morpeh [17]

35% are in display cases which means 65% are on the wall.


this means 195 cars is 65% of the collection.


to get total number of cars in the collection divide 195 by 65%

195/0.65 = 300

Solve simultaneous equations 3x-2y=17 +2x-2y=10
Zarrin [17]

Answer:

(7;2)

Step-by-step explanation:

3x - 2y  = 17 \\  - 2y = 17 - 3x \\ 2x + 17 - 3x = 10 \\ 2x - 3x = 10 - 17 \\  - x =  - 7 \\ x = 7 \\  - 2y = 17 - 21 \\  - 2y =  - 4 \\ y = 2
