Answer:

The sum is a binomial with a degree of 6

Step-by-step explanation:

we have

(3x^{2}y^{2}-2xy^{5})+(-3x^{2}y^{2}+3x^{4}y)

Group terms that contain the same variable

(3x^{2}y^{2}-3x^{2}y^{2})-2xy^{5}+3x^{4}y

0-2xy^{5}+3x^{4}y

-2xy^{5}+3x^{4}y

The sum is a binomial ( two terms) with a degree of 6

-2xy^{5} has a degree of 6 (x has an exponent of 1, y has 5, and 1+5=6)

Jaina and Tomas compare their compound interest accounts to see how much they will have in the accounts after three years. They

stellarik [79]

Formula for compound interest is

Interest = Amount - Principal

Interest = $P(1+r)^{t}$ - P

Where r = rate in percent

t = time in years

For Jaina,

P = $300

r= 7%

t = 3 yrs

So, Interest = $300(1+0.07)^{3}$ - 300

For Tomas

P = $400

r= 4%

t = 3 yrs

So, Interest = $400(1+0.04)^{3}$ - 400

So pair of equations for Jaina and Tomas are

Interest = $300(1+0.07)^{3}$ - 300

Interest = $400(1+0.04)^{3}$ - 400

Find the slope please

zavuch27 [327]

Hi student, let me help you out! :)

. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

We are asked to find the slope of this graph; we are provided with two points:

$\star~\mathrm{(6,0)}$

$\star~\mathrm{(0,-5)}$

$\triangle~\fbox{\bf{KEY:}}$

What we need in order to find the slope are two points and the slope formula.

Here's the formula:

$\star~\boxed{\mathrm{\cfrac{y2-y1}{x2-x1}}}$

Where

y2 and y1 are y-coordinates

x2 and x1 are x-coordinates

Substitute the values:

$\star~\mathrm{\cfrac{-5-0}{0-6}}}$

Simplify!

$\star~\mathrm{\cfrac{-5}{-6}}}$

Simplify more!

$\star~\mathrm{\cfrac{5}{6}}$

Hope it helps you out! :D

1 and 2 are supplements, 3 and 4 supplements and 1 =4. prove 2=3<br>

Ne4ueva [31]

Step-by-step explanation:

Supplementary angles are angles that have the sum of their angles to be 180°. Hence if <1 and <2 are supplements, then <1+<2 = 180°.... 1

Similarly if <3 and <4 are supplements, then <3+<4 = 180° ....... 2

Equating the left hand side of both equations since they are both equal to 180°, we will have;

<1+<2 = <3+<4 ....... 3

From the question we are told that <1 = <4, substituting this condition into equation 3;

From 3; <1+<2 = <3+<4

<4+<2 = <3+<4 (since <1 = <4)

subtract <4 from both sides

<4+<2 -<4= <3+<4 -<4

<2 = <3 (Proved!)
