Answer:
The system determinant is 18.
Step-by-step explanation:
Given Equation are:
4x - 2y = 5 (1)
3x + 3y = 7 (2)
The determinant of the two equations, ax - by = X and cx - dy = Y can be written as:
(iii)
<u>In this case,</u>
<u />
a = 4
b = -2
c = 3
d = 3
By putting these value in the equation iii, we get:
=> (4)(3) - (-2)(3)
=> 12 - (-6)
=> 12 + 6
=> 18
Therefore, the system determinant is 18.
<span>A linear pair is a pair of adjacent angles formed when two lines intersect.
Linear pair angles add up to 180 degrees because they lie on a straight line.
Let x = smaller angle
Let 5x - 18 = bigger angle
x + 5x -18 = 180
6x = 198
x = 198/6
x = 33
The smaller angle is 33 degrees and the bigger is 147 degrees</span>
Answer:
false
Step-by-step explanation:
5+2=15÷(3+2)
5+2=15÷5
7=15÷5
7=3
false because they are different
The phrases that can be represented as the algebraic expression, 3n - 3 are: <em>Option 3 and Option 5.</em>
Let's translate each of the given phrases to algebraic expressions in order to determine which of them can be represented as 3n - 3.
<em>Option 1:</em>
3 fewer than n is represented as, n - 3
<em>Option 2:</em>
difference between n and 3 is represented as, n - 3.
<em>Option 3:</em>
3 times n is 3n
3 fewer than 3n is represented as 3n - 3.
<em>Option 4:</em>
product of 3 and n is represented as 3n.
<em>Option 5:</em>
3 less than 3n is represented as 3n - 3.
Therefore, the phrases that can be represented as the algebraic expression, 3n - 3 are: <em>Option 3 and Option 5.</em>
