Answer:
(3,2)
Step-by-step explanation:
y = −2x + 8
y = x − 1
Substitute the second equation into the first equation for y
y = -2x+8
x-1 = -2x+8
Add 2x to each side
x-1+2x = -2x+8+2x
3x -1 = 8
Add 1 to each side
3x-1+1 = 8+1
3x =9
Divide by 3
3x/3 = 9/3
x=3
Now find y
y = x-1
y =3-1
y=2
(3,2)
The equation for Pythagorean theorem is
a^2 + b^2 = c^2
c = the hypotenuse of a right angle, the longest sides
a, and b is the shorter sides of the right angle
Since we have the hypotenuse, and one number for the other side, cut the other side (6) in half because of how a area of a triangle is based off the equation, h x b divided by 2 = A
Plug it into the equation above:
3^2 + b^2 = 8^2
9 + b^2 = 64
b^2 = 55
b = √55
D. x = √55 is your answer
Answer:
A = 8, B = 6, C = 4 , D = 7
Top = 29
Side = 20
Step-by-step explanation:
Last row : A + A + A + A = 32 ==> A = 8
First row : D + A + D + D = 3D + 8 = 29
3D = 21 ==> D = 7
Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27
2B = 12 ==> B = 6
Third column : D + A + C + A = 27
7 + 8 + C + 8 = 27 ==> C = 4
