Which expression gives the distance between the points (4, 6) and (7, -3)?
Ugo [173]
The distance formula is
\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}.  In the ordered pair (4, 6), 4 is the <em /><em>x</em>-coordinate and 6 is the <em /><em>y</em>-coordinate.  In the ordered pair (7, -3), 7 is the <em>x</em>-coordinate and -3 is the <em>y</em>-coordinate.  Substituting those values in gives us
\sqrt{(4-7)^2+(6--3)^2}.  Since subtracting a negative is the same as adding a positive, we now have

Solve the equation 2/5x-1=9. Complete each step of the solution and check your solution
Fofino [41]

Answer:

x = 25

Step-by-step explanation:

2/5x - 1 = 9

Add 1 to both sides

2/5x = 10

Multiply by 5 on both sides

2x = 50

Divide by 2 on both sides

x = 25

Check the answer:

Plug in 25 for x

2/5(25) - 1 = 9

10 - 1 = 9

9 = 9

The answer is correct.

Pls help me im confused! <br> angle #1 = x = ?<br><br> angle #2 = X + 30 = ?
sasho [114]

When the sum of two angles measures up to 90° then these angles are known as complementary angles of each other. The measure of ∠1 is 30°, while the measure of ∠2 is 60°.

<h3>What are Complementary Angles?</h3>

When the sum of two angles measures up to 90° then these angles are known as complementary angles of each other.

for example, ∠x + ∠y = 90°, therefore, the ∠x and ∠y are the complementary angles of each other.

Since the two angles together form a 90° angle. The angles are complementary to each other, therefore, we can write,

∠1 + ∠2 = 90°

x + x + 30 = 90°

2x = 60°

x = 30°

Thus, the measure of the angles can be written as,

∠1 = x = 30°

∠2 = x+30° = 60°

Hence, the measure of ∠1 is 30°, while the measure of ∠2 is 60°.
