A) The solution is the point where the lines intersect: (5, 2.5)
b) The horizontal line has equation
.. y = 2.5
The downward-sloping line can be written in intercept form as
.. x/10 +y/5 = 1
or in standard form as
.. x +2y = 10 . . . . . . . . . (multiply the above equation by 10)
Answer:
H(n) = 234⁽ⁿ⁻¹⁾
Step-by-step explanation:
Hello,
The first thing to do when finding an explicit equation is to determine if the sequence is arithmetic or geometric.
In this question, the sequence is a geometric progression.
h(n) = h⁽ⁿ⁻¹⁾.(-9)
a = -26
r = common difference
a(n) =ar⁽ⁿ⁻¹⁾
h(n) = -26 × (-9)hⁿ⁻¹⁾
h(n) = 234⁽ⁿ⁻¹⁾
4/9 *9/4 =1
Use the reciprocal to find your answer :)

Answer:
1
Step-by-step explanation:
There can be 0, 1 or infinitely many solutions. 0 if they are parallel and are different lines, 1 if the slopes are different, and infinitely many if they are the same line.
2x - 4y = 8
x + y = 7
Change to y = mx + b
y = (1/2)x - 2
y = -x + 7
The slopes are different so there is 1 solution.
Hope this helps Please mark as brainliest and have a blessed day
Put the values of the variables in place of the variables in the expression, then do the arithmetic.
