x+7=0 x-4=0 (x+7)(x-4)=0 how would you compare the three questions? what value(s) of x would make each equation true?

Answers

$x+7=0 \n \boxed{x=-7} \n \n x-4=0 \n \boxed{x=4} \n \n (x+7)(x-4)=0$
$x+7=0$ or $x-4=0$
$x=-7$ or $x=4$

S= {-7 ; 4}

$(x+7)(x-4)=0 \Leftrightarrow x+7=0 \vee x-4=0\n x=-7 \vee x=4$

What is another way to write the ratio 3 to 10

Answers

Under ratio and proportion, there are a couple of ways you can use aside from using words to establish the relationship between 2 numbers.

One would be in a fraction form where "3 to 10" can be written as "3/10", or using a colon between the two numbers, where it would be written as "3:10". It is necessary to understand that these forms all mean the same, even if they look really different.

[6.02] For the following system, if you isolated x in the first equation to use the Substitution Method, what expression would you substitute into the second equation?-x - 2y = -4
3x + y = 12

Answers

To use the substitution method we need to convert one equation in terms of a certain variable and substitute this equation to the other equation. For this case we are asked to substitute the first equation to x in the second equation. Therefore, the equation to substitute is:

-x - 2y = -4
x = 4 - 2y

Answer:B

Step-by-step explanation:

2y-4

Solve the equation for y(x-3)^=4y-12

Answers

remember yuo can do anything to an equaiton as long as you do it to both sides

(x-3)=4y-12
x-3=4y-12
add 12 both sides
x-3+12=4y+12-12
x+9=4y+0
x+9=4y
divid both sides by 4
(x+9)/4=y

First

y(x + -3) = 4y + -12\

Then you would Reorder the terms:
y(-3 + x) = 4y + -12 (-3 * y + x * y) = 4y + -12

And theses (xy + -3y) = 4y + -12(xy + -3y) = 4y + -12

then we would Reorder the terms:xy + -3y = -12 + 4y

then you would Move all terms containing x to the left, all other terms to the right.

so that means we would Add '3y' to each side of the equation.xy + -3y + 3y = -12 + 4y + 3y

then you would want to Combine like terms: -3y + 3y = 0xy + 0 = -12 + 4y + 3y xy = -12 + 4y + 3y
Combine these two 4y + 3y = 7yxy = -12 + 7y
then we would want to Divide each side by 'y'.x = -12y-1 + 7

so after simplifying it, it would be x = 7 + -12y-1
