Equations by substitution<br> y=3x-7; 2x+4y=14

Bad White [126]

Let's plug in y=3x-7 into 2x+4y=14
2x+4 (3x-7)=14
Distribute
2x+12x-28=14
Add
14x-28=14
Add 28 to both sides
14x=42
Divide
X=3
Y=3 (3)-7
Y=9-7
Y=2
(3,2) A the solution is (3,2)

Left side angle = 180-150-12 = 18 degrees

10 / sin 12 = c / sin 18

c = 10 * sin 18 / sin 12

c = 14.9 cm to nearest tenth

Which ordered pair is the best estimate for the solution of the system of equations?

Brums [2.3K]

For this case we have the following system of equations:

$y = - \frac {3} {4} x-2\\y = x + 6$

Equaling the equations we have:

$- \frac {3} {4} x-2 = x + 6\\-2-6 = (1+ \frac {3} {4}) x\\-8 = \frac {7} {4} x\\-32 = 7x\\x = \frac {-32} {7}\\x = -4.57$

The variable y:

$y = -4.57 + 6 = 1.43$

Thus, we can round the solution as:

$(x, y): (- 4.5; 1.5)$

It is verified with the graph
