Answer:

x=16⁰

Step-by-step explanation:

I AM NOT QUITE SURE OF THE ANSWER, but they are vertically opposite angles which in turn means that they are equal.

so you can equate the two sums they have given.

3x-3 = 2x+13

Take the numerical terms onto the right hand side and the 'x-terms' to the left hand side.

3x-2x = 13+3

That would leave you with,

x=16⁰

Answer: 18 and 99 degrees

Step-by-step explanation:

The sum of the measures of the other 2 angles is 360 - 219 - 24 = 117 degrees.

So the other two angles measure (2/13)(117)=18 degrees and (11/13)(117)=99 degrees

Answer:

-5/3

Step-by-step explanation:

We have two points on the line  ( 0,2) and ( 3, -3) so we can use the slope formula to find the slope

m = ( y2 -y1)/(x2-x1)

    = ( -3 -2)/(3-0)

   = -5/3

Answer:

(4x -25), (2x + 11)

Step-by-step explanation:

STEP1: Equation at the end of step 1

(23x2 - 6x) - 275

STEP2: Trying to factor by splitting the middle term

 2.1     Factoring  8x2-6x-275 

The first term is,  8x2  its coefficient is  8 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -275 

Step-1 : Multiply the coefficient of the first term by the constant   8 • -275 = -2200 

Step-2 : Find two factors of  -2200  whose sum equals the coefficient of the middle term, which is   -6 .

     -2200   +   1   =   -2199     -1100   +   2   =   -1098     -550   +   4   =   -546     -440   +   5   =   -435     -275   +   8   =   -267     -220   +   10   =   -210     -200   +   11   =   -189     -110   +   20   =   -90     -100   +   22   =   -78     -88   +   25   =   -63     -55   +   40   =   -15     -50   +   44   =   -6   That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -50  and  44 

                     8x2 - 50x + 44x - 275

Step-4 : Add up the first 2 terms, pulling out like factors :

                    2x • (4x-25)

              Add up the last 2 terms, pulling out common factors :

                    11 • (4x-25)

Step-5 : Add up the four terms of step 4 :

                    (2x+11)  •  (4x-25)

             Which is the desired factorization

Final result :

(4x - 25) (2x + 11)

Answer:

you look at the sequence in which the pattern is moving

The function [tex]f(x)=\left(x-5\right)\left(x+1\right)[/tex] has a vertex at (2, -9).

The quadratic function can be represented by a quadratic equation in the Standard form: [tex]ax^2+bx+c[/tex] where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero ([tex]a\neq 0[/tex]) and the degree of the function must be equal to 2.

For solving this question, you should find the vertex of quadratic equation (h,k). Where, [tex]h=-\frac{b}{2a}[/tex] . On the other hand, the value of the k-coordinate will be found when you replace the value of h in the equation of your question.

     1.  [tex]f(x)=-(x-3)^2[/tex]

        Write this equation in Standard form:

                          [tex]f(x)=-(x^2-6x+9)\\ \\ f(x)=-x^2+6x-9[/tex]

        Find h, using the formula  [tex]h=-\frac{b}{2a}[/tex]

             [tex]h=-\frac{b}{2a} =-\frac{6}{2*(-1)} =-\frac{6}{-2}=-(-3)=3[/tex]

        Find k, replacing x for the value of h

         [tex]-x^2+6x-9\\ \\ -(3)^2+6*3-9=-9+18-9=-18+18=0[/tex]

      The vertex of quadratic equation is (3,0). Incorrect Option.

     2.  [tex]f(x)=(x+8)^2[/tex]

        Write this equation in Standard form:

                          [tex]f(x)=x^2+16x+64[/tex]

        Find h, using the formula  [tex]h=-\frac{b}{2a}[/tex]

             [tex]h=-\frac{b}{2a} =-\frac{16}{2*1} =-\frac{16}{2}=-8[/tex]

        Find k, replacing x for the value of h

         [tex]x^2+16x+64\\ \\ (-8)^2+16*(-8)+64=64-128+64=128-128=0[/tex]

  The vertex of quadratic equation is (-8,0). Incorrect Option.

   3.  [tex]f(x)=\left(x-5\right)\left(x+1\right)[/tex]

        Write this equation in Standard form:

                          [tex]f(x)=(x^2+x-5x-5)\\ \\ f(x)=(x^2-4x-5)[/tex]

        Find h, using the formula  [tex]h=-\frac{b}{2a}[/tex]

             [tex]h=-\frac{b}{2a} =-\frac{-4}{2*1} =-\frac{-4}{2}=-(-2)=2[/tex]

        Find k, replacing x for the value of h

         [tex]x^2-4x-5\\ \\ 2^2-4*2-5=4-8-5=-4-5=-9[/tex]

   The vertex of quadratic equation is (2,-9). Correct Option.

   4.  [tex]f(x)=-\left(x-1\right)\left(x-5\right)[/tex]

        Write this equation in Standard form:

                          [tex]f(x)=-\left(x-1\right)\left(x-5\right)\\ \\ f(x)=-(x^2-5x-x+5)\\ \\ f(x)=-(x^2-6x+5)\\ \\ f(x)=-x^2+6x-5[/tex]

        Find h, using the formula  [tex]h=-\frac{b}{2a}[/tex]

             [tex]h=-\frac{b}{2a} =-\frac{6}{2*(-1)} =-\frac{6}{-2}=-(-3)=3[/tex]

        Find k, replacing x for the value of h

         [tex]-x^2+6x-5\\ \\ -(3)^2+6*3-5=-9+18-5=18-14=4[/tex]

The vertex of quadratic equation is (3,4). Incorrect Option.

[tex]\frac{64}{27}[/tex]

Step-by-step explanation:

We can use the "keep-change-flip" method to divide fractions

   Keep: [tex]\frac{8}{9}/\frac{3}{8}[/tex]

Change: [tex]\frac{8}{9}*\frac{3}{8}[/tex]

      Flip: [tex]\frac{8}{9}*\frac{8}{3}[/tex]

Answer:

The angles are 54 2/3 degrees and 115 1/3 degrees

Step-by-step explanation:

make an equation for the angles x being one angle and y being the other

16+ 2x =y

Supplementary angles add to 180

x + y = 180

Fill in y with the first equation

x + 16 +2x =180

simplify

3x +16 =180

subtract 16 from both sides

3x = 164

divide both sides by 3

x = 54 2/3

Insert the value of x into the first equation then simplify

16 + 2(54 2/3) =y

16 + 109 1/3 =y

115 1/3 =y
