Answer:2
Step-by-step explanation:
Answer:
This equation is in standard form: ax 1+bx+c=0. Substitute 9 for a, 16 for b, and −112 for c in the quadratic formula 2a−b±b2−4ac.x= 2×9−16± 16^2−4×9(−112)Square 16.x=2×9−16±256−4×9(−112) Multiply −4 times 9.x=2×9−16± 256−36(−112) Multiply −36 times −112.x=2×9−16±256+4032 Add 256 to 4032.x=2×9−16±4288 Take the square root of 4288.x=2×9−16±8+67 Multiply 2 times 9x=18−16±8=67

Use slope formula
(y1-y2)/(x1-x2)
(16 - -19)/(0 - 4) = 35/-4
Answer: 2=x
Step-by-step explanation:
4x-1 + 2x-1 = 5x
First combine like terms together
4x-1 + 2x-1 is 4x+2x-1-1
4x+2x-1-1 =6x-2
4x-1 + 2x-1=6x-2
6x-2=5x
The oppisite of 6x is -6x so -6x on both sides of equation to keep it balanced
6x-6x-2=5x-6x
0-2=-1x
-2=-1x
Divide both sides of the equation by -1 since -1 is being multiplied by x and the oppisite of multiply is divide
-2/-1=-1x=-1
2=x
You must “reverse” the inequality sign to make the statement true: When you multiply by a negative number, “reverse” the inequality sign. Whenever you multiply or divide both sides of an inequality by a negative number, the inequality sign must be reversed in order to keep a true statement.
