Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have the equation of a line in the standard form:
Convert to the slope-intercept form:
<em>subtract 12x from both sides</em>
<em>divide both sides by (-4)</em>
Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1 ⋅ − 1 = − 1 2 − 2 c − 9 c 2
// Solve equation [1] for the variable x
[1] x = 2y - 1
// Plug this in for variable x in equation [2]
[2] 2•(2y-1) - 5y = -3
[2] - y = -1
// Solve equation [2] for the variable y
[2] y = 1
// By now we know this much :
x = 2y-1
y = 1
// Use the y value to solve for x
x = 2(1)-1 = 1
4 x = 36
Step-by-step explanation:
Because the groups have an equal number of students, we assume that each of the groups has <em>x </em>number of students.
Therefore since there is <em>x</em> number of students in each of the 4 groups, there is 4 * x number of total students in all groups combined.
Since the question already indicates that there are a total of 36 students in the class, then we can indicate that..
4x = 36
17 because Caronline is twice as old as Sarah which makes Sarah 14 and Jacob is 3 years older then Sarah
