What is -2(x + 7) in math

1 answer:

5 0

Apply the distributive property, which says that a(b+c)= ab+ac.

-2(x+7)= -2(x)+ -2(7)

-2(x)= -2x
-2(7)=-14

Put it together.

Final answer: -2x-14

Which polynomial correctly combines the like terms and expresses the given polynomial in standard form?

Lera25 [3.4K]

Answer:

The first option

Step-by-step explaination:

$9 {xy}^{3} - 4 {y}^{4} - 10 {x}^{2} {y}^{2} + {x}^{3} y + {3x}^{4} + {2x}^{2} {y}^{2} - 9 {y}^{4}$

$(- 4 {y}^{4} - 9 {y}^{4} ) + ( - 10 {x}^{2} {y}^{2} + {2x}^{2} {y}^{2}) + 9 {xy}^{3}+ {x}^{3} y + {3x}^{4}$

$- 13 {y}^{4} - 8 {x}^{2} {y}^{2} + 9 {xy}^{3} + x {}^{3} y + 3x {}^{4}$

$- 13 {y}^{4} + {3x}^{4} - 8 {x}^{2} {y}^{2} + {x}^{3} y + {9xy}^{3}$

Graph a triangle on the coordinate plane. Choose 1 transformation (reflection, rotation,

BlackZzzverrR [31]

Answer:

The answer in the procedure

Step-by-step explanation:

we have the right triangle ABC

The pre-image coordinates are

$A(0,0),B(0,3),C(4,0)$

The transformation to use is the translation

The rule of the translation is

$(x,y)-----> (x+10,y)$

That means----> The translation is 10 units to the right

The image coordinates are

Applying the rule of the translation

$A'(0+10,0)=A'(10,0)$

$B'(0+10,3)=B'(10,3)$

$C'(4+10,0)=C'(14,0)$

using a graphing tool

Given: 3x < -6. Choose the solution set. a. {x | x < -2} b. {x | x > -2} c. {x | x < 2} d. {x | x > 2}

schepotkina [342]

The answer is a.{x | x < -2}. The rule of the calculation of inequation is if the equation divided by the same positive number, the direction of the sign of inequality will not change.
