Answer:
<h2>y = 4x + 4</h2>
Step-by-step explanation:
The slope-intercept form:
m - slope
b - y-intercept
Parallel lines have the same slope.
We have y = 4x + 2 → m = 4.
The slope of parallel line is m = 4 and the y-intercept b = 4.
Therefore we have the equation of a line:
2n-9-5-8n+4n
= 2n-14-4n
=2n-14
(3, -2)
Step-by-step explanation:
y = -2x + 4
-x + 3y = -9
-x + 3 (-2x + 4) = -9
-x + -6x + 12 = -9
-7x = - 9 – 12
-7x = - 21
X = 3
We substitute x with 3 to evaluate y;
-3 + 3y = -9
3y = -6
y = -2
Elimination Method;
y = -2x + 4
-x + 3y = -9
We arrange the equations for substitution;
2x + y = 4
-x + 3y = -9
We multiply the first equation with 3 so we can substract one variable to zero;
3 (2x + y = 4)
= 6x + 3y = 12
Then we subtract the two;
6x + 3y = 12
-x + 3y = -9
7x = 21
x = 3
We evaluate y by substitution x with 3 in one of the equation;
-x + 3y = -9
-3 + 3y = -9
3y = -6
y = -2
The final answer expressed as a coordinate point is;
(3, -2)
Since the problem says VALUE, it is talking about the amount of money a nickel and dime are worth has to be included in the expression.
5(0.05) + 0.10x
