Answer:

(7,0) ---> (x = 7) and (y = 0)

Step-by-step explanation:

2x – 9y = 14

x= -6y +7     <-- (Substitute for x to above equation)

---------------------------------------------------------------------------------------------------------

2(-6y +7)– 9y = 14

-12y + 14 - 9y = 14    <-- combine like terms

-21y + 14 = 14  

        -14 = -14   <-- inverse operation on both sides

      -21y = 0     <-- Divide

          y = 0  <--- Substitute for y to get x  ↓

-------------------------------------------------------------------------------------------------------

2x – 9y = 14

2x – 9(0) = 14     <-- Substituted y from above

          2x = 14     <-- Divide

            x = 7

Answer:65

Step-by-step explanation:

Answer:

65

Step-by-step explanation:

Hey There!

So where the given angles are is in a triangle called an isosceles triangle

In isosceles triangles to of the angles are congruent

The congruent angles are near the letters Q and R

we are given that angle 1 =50

so to find the missing angles we subtract 180 from 50 and divide by 2

180-50=130

130/2=65

so angle 2 = 65

It looks like you have

tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = cot(x) + tan(x) + 1

but this is not an identity.

Take for instance x = 3π/4. Then

tan(3π/4) = -1

cot(3π/4) = -1

so that

tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = 0

while

cot(x) + tan(x) + 1 = -1

and of course 0 ≠ -1.

Answer:

Step-by-step explanation:

a right triangle is half of a rectangle and the area of a rectangle is

                 area of rectangle = length × width

Area of a triangle is one half times the length times the width

                 area of triangle =  1/2 × length × width

in this case

                length is the number of the y units  

                width is the number of x axis unit      

    area of triangle =  1/2 × length × width  

    area of triangle =  1/2 × (y units) × (x units)       you need to count and insert

                                                                                the number of units into the

                                                                                equation

                                                                                       and see if you get one of

Answer:C

Step-by-step explanation:

Answer:

A) 252pi

Step-by-step explanation:

The volume of a sphere is [tex]\frac{4}{3}\pi r^{3}[/tex]

First, let's find the diameter of the large sphere.

If D=12, then R=6

[tex]\frac{4}{3}\pi 6^{3}=288\pi[/tex]

Then, we need to find the volume of the smaller sphere

[tex]\frac{4}{3}\pi 3^{3}=36\pi[/tex]

[tex]288\pi -36\pi =252\pi[/tex]

Hope this helps :)

The central angle is twice the inscribed angle (same arc).

The inscribed angle forms a supplementary angle with the missing one (opposite angles of the cyclic quadrilateral).

The missing angle is:

Answer:

[tex] - 12[/tex]

Step-by-step explanation:

1) Simplify 5 - 3 to 2.

[tex](1 - 2) \times 2 + 5 \times - 2[/tex]

2) Simplify 1 - 2 to -1.

Answer:

D

Step-by-step explanation:

To find:

Any two quadratic equations​.

Solution:

The general form of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

[tex]1x^2+1x+1=0[/tex]

[tex]x^2+x+1=0[/tex]

One quadratic equation is [tex]x^2+x+1=0[/tex].

For a=3,b=-1,c=5, we get

[tex]3x^2+(-1)x+5=0[/tex]

[tex]3x^2-x+5=0[/tex]

Therefore, the two quadratic equations are [tex]x^2+x+1=0[/tex] and [tex]3x^2-x+5=0[/tex].

The error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

The SSA congruence theorem only exist and holds true, only if the congruence non-included angles in both triangles are either obtuse or right angles and have two pairs of congruent sides.

Thus:

The two triangles given have a pair of non-included congruent angles that are less than 90 degrees.

Therefore, the error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.
