If 3x + 4y = 10 and 2x + 3y = 6, then x + y = ?
zavuch27 [327]

Answer:

x + y = 4

Step-by-step explanation:

Given the 2 equations

3x + 4y = 10 → (1)

2x + 3y = 6 → (2)

Subtract (2) from (1) term by term on both sides

x + y = 4

Copy DEF to the line so that S is the vertex. This task will be complete when you have constructed an angle with vertex S that i
tino4ka555 [31]

Explanation:

There are numerous videos and web sites that can show you the process of copying an angle. Some are animated. The best we can do here is show you a diagram with instructions. Of course, your curriculum materials already provide that.

__

1. Set the compass to a convenient radius. Use that to draw an arc through rays ED and EF, using point E as the center.

2. Without changing the compass setting, draw a similar arc using S as the center, making sure it crosses the line containing S and extends far enough to accommodate the following steps. (In the attached, we show a full circle, because the tool we used won't draw an arc with a specific radius.)

3. Mark the points where the arc crosses ED as G, and where it crosses EF as H. Mark the point where the arc crosses the line containing S as I.

4. Set the compass radius to the distance GH. Using I as the center draw an arc with that radius so that it crosses the one made in step 2. Call that intersection point J. (Again, we have shown a circle because of the limitations of the tool being used for our diagram.)

5. Draw ray SJ to complete the angle copy.

Match each graph with the correct slope of the line. drag and drop the answer
OLEGan [10]

Answer/Step-by-step explanation:

✔️Slope of the first graph:

Using two points on the line, (0, 1) and (3, 2),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{3 - 0} = \frac{1}{3}

Slope = ⅓

✔️Slope of the second graph:

Using two points on the line, (0, 0) and (1, 1),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 0}{1 - 0} = \frac{1}{1} = 1

Slope = 1

✔️Slope of the third graph:

Using two points on the line, (0, 1) and (2, 2),

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{2 - 0} = \frac{1}{2}

Slope = ½

Which ordered pairs are solutions to the inequality 2x+3y≥−1 ?
Pavlova-9 [17]
There are many pairs that are solutions to this inequality. You can find them all by graphic this on a coordinate plane and then shading the region. 

You can also plug any of the ordered pairs that they give you into the equation and see if they produce a true statement.
