(5x^4-3x^3+2)-(-3x^4+2x^2-5)

Here's the solution :

8-3-2+7

Step-by-step explanation:

The first thing to do in this problem is distribute the negative in front of (). This makes it .

From here you can remove the parenthesis and combine like terms. 5 combines with 3 to get 8 and 2 and 5 combine to get 7. The -3 and -2 cannot combine with anything since they don't share any like terms.

Using the combinations, bring all of the terms back together and you get 8-3-2+7

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
