Find X, AB, BC, AC if B is the midpoint of AC
Artemon [7]

Step-by-step explanation:

it all starts with the understanding that "midpoint" means that the line segments on both sides have the exact same length.

this is the same as "cut a pizza or a cake in half".

therefore, we know

10x + 1 = 8x + 13

2x + 1 = 13

2x = 12

x = 6

AB = 10x + 1 = 10×6 + 1 = 60 + 1 = 61

BC = AB but to control : 8×6 + 13 = 48+13 = 61

correct.

AC = AB + BC = 61 + 61 = 122

When the two equations are graphed on a coordinate plane, they intersect at two points.
Law Incorporation [45]

Answer:

(0,4) and (-2,0)

Step-by-step explanation:

y=3x²+4x+4

y = -2x +4

3x²+4x+4 = - 2x +4

3x²+6x=0

3x(x+2)=0

x=0, x= -2

x=0, y=-2x+4= -2*0 + 4 =4,   (0,4)

x= - 2, y = 2x + 4= 2*(-2) +4=0,    (-2,0)

The centre of the stained glass window is in the shape of a regular polygon. What are the measures of the interior angle of the
tester [92]

Answer:

67.5 - 67.5 - 45 °

Step-by-step explanation:

Sum of INTERIOR angles of a polygon

  (n-2) * 180      <====<u>ya just have to remember/know this !</u>

n is the number of sides     n = 8 in this case

(8-2)*180 = 1080 °     < === this is the SUM of the 8 interior angles

        EACH interior angle is then   1080 / 8 = 135 °

  you can see from the picture that each of the two outside angles of the green triangle are 1/2 of this = 67.5° each

   so the triangle measurements are

              67.5 - 67.5 - 45     ( they have to sum to 180 for triangle)

Karla can buy guppies for $0.90 each at the corner pet store. If she has $13.50, how many guppies can she buy? 
pshichka [43]

All we have to do here is divide $13.50 by $0.90 to figure out how many guppies she can buy

$13.50 ÷ $0.90 = 15

Therefore, Karla can buy <u>15 guppies</u> with $13.50

Hope this helps you

Brainliest would be appreciated
