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)

H(1) = -26<br>h(n) = h(n − 1).(-9)<br>Find an explicit formula for h(n).​
a_sh-v [17]

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⁾

How many solutions does this system have?
8_murik_8 [283]

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

I need help answering
jekas [21]

Put the values of the variables in place of the variables in the expression, then do the arithmetic.

8p+3q-18\\\\=8\left(\dfrac{1}{2}\right)+3(7)-18=\dfrac{8}{2}+21-18\\\\=4+21-18\\\\=25-18\\\\=\bf{7}
