Step-by-step explanation:

supplementary means that two adjacent angles form a line ( 180 degrees ).

complementary means two adjacent angles form a ( 90 degrees ).

adjacent just means next angle..

corresponding is like it is corresponding with another angle.. it is symmetrical to another angle

a/c = d/a

you would cross multiply to get aa = cd

aa = a^2

so you would have a^2 = cd

Solve this quadratic equation. x^2+2x-22=0

torisob [31]

X=⁻3 and x=1
because
a+b=2 which means a=3 and b=⁻1 which added up equals 2
a×b=⁻22 which means that 11 which is a×⁻2 which is b=⁻22

X + 2y = 5 x - 3y = 7 What is the value of the y-determinant? -2 -1 2

grandymaker [24]

Answer:

y-determinant = 2

Step-by-step explanation:

Given the following system of equation:

x + 2y = 5
x - 3y = 7

Let's represent it using a matrix:

$\left[\begin{array}{ccc}1&2\\1&-3\end{array}\right] = \left[\begin{array}{ccc}5\\7\end{array}\right]$

The y‐numerator determinant is formed by taking the constant terms from the system and placing them in the y‐coefficient positions and retaining the x‐coefficients. Then:

$\left[\begin{array}{ccc}1&5\\1&7\end{array}\right]$

y-determinant = (1)(7) - (5)(1) = 2.

Therefore, the y-determinant = 2
