Answer:
x = 34
Step-by-step explanation:
complementary angle sum to 90°
sum the 2 angles and equate to 90
x + x + 22 = 90
2x + 22 = 90 ( subtract 22 from both sides )
2x = 68 ( divide both sides by 2 )
x = 34
Answer:
b
Step-by-step explanation:
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
the answer is false because it can be in the Y or the X axis
Answer:
(2,-2)
Step-by-step explanation:
the x-intercept is 2
and y-intercept is-2
x-intercept is when you have a number comma 0 e.g 3,0. 2,0
y-intercept is when u have 0 comma a number e.g 0,2 0,-5
