Graph the equations to solve the system. y = x + 4 y = -x - 6 choose the correct answer a.) solutions: all numbers on the line

1 answer:

8 0

Y = x + 4
y = -x - 6

x + 4 = -x - 6
x + x = -6 - 4
2x = -10
x = -10/2
x = -5

y = x + 4
y = -5 + 4
y = -1

one solution : (-5,-1)

38. What is the solution to 2(x - 6) = 14?

ivanzaharov [21]

Answer:

x=13, 16(x-1)

Step-by-step explanation:

For 38, you have to first divide both sides by 2.

This becomes, x-6=7

Add 6 to both sides

x=13.

For 40. You can can distribute the 8.

This makes it 16x-16.

With this you can than, factor out the 16.

16(x-1).

Which ordered pair makes both inequalities true? y < 3x – 1 y > –x + 4 On a coordinate plane, 2 straight lines are shown.

Katen [24]

Answer:

(4,0)

Step-by-step explanation:

we have

$y< 3x-1$ ----> inequality A

$y \geq -x+4$ ----> inequality B

we know that

If a ordered pair is a solution of the system of inequalities, then the ordered pair must satisfy both inequalities (makes true both inequalities)

Verify each ordered pair

case 1) (4,0)

Inequality A

$0< 3(4)-1$

$0< 11$ ----> is true

Inequality B

$0 \geq -(4)+4$

$0 \geq 0$ ----> is true

the ordered pair makes both inequalities true

case 2) (1,2)

Inequality A

$2< 3(1)-1$

$2< 2$ ----> is not true

the ordered pair not makes both inequalities true

case 3) (0,4)

Inequality A

$4< 3(0)-1$

$4< -1$ ----> is not true

the ordered pair not makes both inequalities true

case 4) (2,1)

Inequality A

$1< 3(2)-1$

$1< 5$ ----> is true

Inequality B

$1 \geq -(2)+4$

$1 \geq 2$ ----> is not true

the ordered pair not makes both inequalities true
