The graph of the equation y=2x+b passes through the point (b, -3). Find b. PLZ SHOW WORK!

1 answer:

3 0

Substitute in the points. It doesn't matter if they ar pe variables or not, since the variable b is used already in the equation, making it possible to find.

Substitute in the y value for the y in the equation and do the same for the x.

-3=2b+b
-3=3b
-1=b

b is -1.

Hope this helps!

How can i find percent %

stepan [7]

Answer: You can simply divide the number that you want to turn into a percentage by the whole. So, using this example, you would divide 2 by 5. This equation would give you 0.4. You would then multiply 0.4 by 100 to get 40, or 40%.

The binomial (a 5) is a factor of a2 7a 10. what is the other factor? (a 2) (a 5) (a−2) (a−5)

d1i1m1o1n [39]

An expression has numbers, variables, and mathematical operations. The other factor of the given binomial is a²+7a+10 except (a+5) is (a+2).

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

To find the other factor of the binomial a²+7a+10, we can write it as,

$a^2+7a+10\\\\=a^2+5a+2a+10\\\\=a(a+5)+2(a+5)\\\\=(a+5)(a+2)$
