Answer:
Step-by-step explanation:
The equation of a line in slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the x-intercept = 4 → (4, 0), and y-intercept = 5 → b = 5.
Therefore we have the equation:
Put the coordinates of x-intercept to the equation:
<em>subtract 4m from both sides</em>
<em>divide both sides by (-4)</em>
Finally we have the equation of a line if slope-intercept form:
The standard form:
Convert:
<em>multiply both sides by 4</em>
<em>add 5x to both sides</em>
0.7(3s+4)-1.1s=7.9 equals s=5.1
Answer:
Variable: t
Constant: 18
Step-by-step explanation:
A constant is the number that is known, the variable is unknown. A variable is usually denoted with a letter and a constant with digits. I hope this helps :0)
Sn = a1 * (1 - r^n)
----------
1 - r
n = 5 so answer =
1 * (1 - (1/2)^5
--------------- = 31/16
1 - 1/2
