Answer:
um
Step-by-step explanation:
3x - y = 9
y = -2x + 11
3x - (-2x + 11) = 9
3x + 2x - 11 = 9
3x + 2x = 9 + 11
5x = 20
x = 20/5
x = 4
y = -2x + 11
y = -2(4) + 11
y = -8 + 11
y = 3
solution (where the lines intersect) is (4,3)
Answer:
122 Minutes
Step-by-step explanation:
Start with $16.42
subtract $3 for the monthly fee, 16.42-3= $13.42
he pays $0.11 per minute so that's 13.42 x (1min/0.11) = 122minutes
Answer and Step-by-step explanation:
<em>Rearrange the equation so "y" is on the left and everything else on the right.</em>
<em>Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)</em>
<em>Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).</em>
<em>Solve systems of equations by graphing. A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. </em>
Have a Awesome day!
Answer:
40
Step-by-step explanation:
55% of n is equal to 22.
First, let's make an equation:
(55/100)*n = 22
(11/20)*n = 22 (reduced the fraction)
n = 22/(11/20) (divide both sides by 11/20)
n = 40
Hope this helps!
