Answer:

EF = 13 units

Step-by-step explanation:

Points E and F are the ends of segment EF.

Coordinates of E → (-7, -5)

Coordinates of F → (-2, 7)

Since, length of a segment joining points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

Length of segment = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]

Length of segment EF = [tex]\sqrt{(-7+2)^2+(-5-7)^2}[/tex]

                                     = [tex]\sqrt{(-5)^2+(-12)^2}[/tex]

                                     = [tex]\sqrt{169}[/tex]

                                     = 13

Therefore, length of segment EF is 13 units.

Answer:

13 units.

Answer:

8.4

Step-by-step explanation:

51.24 ÷ 6.1 = 8.4

Although, if you were dividing 6.1 by 51.24, you would have a totally different answer, the answer to 6.1 ÷ 51.24 = 0.119047619047619.

Answer:

65°

Step-by-step explanation:

From the question,

The base angle of an isoceles triangle are equal.

Let the value of the base angles = x°

Sum of angle in a triangle = 180°

⇒ x°+x°+50° = 180°

⇒ 2x°+50° = 180°

⇒ 2x° = 180°-50°

⇒ 2x° = 130°

⇒ 2x°/2 = 130/2

⇒ x° = 65°.

Hence, the size of the other angles is 65°

Answer:

(5, -2)

Step-by-step explanation:

Let's solve the first equation for x:  If x + y = 3, and if we subtract y from both sides, we get x = 3 - y.  Next, substitute 3 - y for x in the second equation:

3(3 - y) + 2y = 11, or

9 - 3y + 2y = 11

Combining like terms:  -3y + 2y = 11 - 9, or

-y = 2, or y = -2.

Then, from the equation x = 3 - y, which we found earlier,

x = 3 - (-2) = 5

Then the solution is (5, -2)

36-14=22.

Conclusion: Devon had mad 22 party favors by that point.

Answer:

y=4

Step-by-step explanation:

First, you should simplify this equation. To do that, we need to multiply 3 by 4y and 3 by 7. This will make the equation 12y+21=69. Subtract 21 from both sides to isolate y. This will make the equation 12y=48. You want the y to be by itself so you have to divide 12 by each side to get y=4. Therefore, the answer is y=4.

Answer:

[tex]x = 3\pm 5i[/tex]

Step-by-step explanation:

Quadratic formula

[tex]x = \frac{6 \pm \sqrt{36-4(1)(34)}}{2(1)}[/tex]

There are no real solutions since the discriminant is negative.

Simplify this to get x = 3+5i, 3 -5i

The SOH CAO TOA identity is used to determine the acute angles of a right triangles. The terminal point of ø is (-1,0), what is tan ø is 0

Given the terminal point (-1, 0), the value of tanø is expressed as:

tanø = opposite/adjacent

tanø = y/x

From the coordinate given:

x = -1

y = 0

Substitute

tanø = 0/-1
tanø  = 0

Hence the terminal point of ø is (-1,0), what is tan ø is 0

Answer:

y = 5x - 8

Step-by-step explanation:

Here. we want to find the equation of the line

The general form is;

y = mx + b

where m is the slope and b is the y—intercept

To get the slope, we can pick any two points on the line

These are;

(2,2) and: (3,7)

we have the slope as follows;

m = (y2-y1)/)x2-x1) = (7-2)/3-2) = 5/1 =5

So we have;

y = 5x + b

To get b , use any point on the line and substitute its coordinates

using (3,7)

7 = 5(3) + b

7 = 15 + b

b = 7-15

b = -8

So the equation of the line is (

y = 5x - 8

Step-by-step explanation:

7x - -6x = 7x + 6x = 13x.

-10 - -8 = -10 + 8 = -2

13x - 2

Answer:

13x - 2

Step-by-step explanation:

( 7x - 10 ) - ( -6x - 8 )

First, distribute the minus sign outside of the second parenthesis. Multiply each term within the second parenthesis by the minus sign.

( 7x - 10 ) + ( (-1)(-6x) + (-1)( -8))

Simplify,

( 7x - 10 ) + ( 6x + 8 )

Remove parenthesis,

7x - 10 + 6x + 8

Simplify, combine like terms,

7x - 10 + 6x + 8

13x - 2
