Answer:

x=15, y=21

Step-by-step explanation:

6x-11 is opposite angle theorem.

a triangle is 180 degrees.

triangle 2: (6x-11)+(x+5)+81 = 180

6x-11+x+5+81=180

7x=105

x=15

triangle 1: (6x-11)+(y+14)+(4y-18)=180

substitute x = 15

6(15)-11+y+14+4y-18=180

90-11+y+14+4y-18=180

5y=105

y=21

Find the slope of the line (-3,-3) (1,1)

Volgvan

Answer: The slope is m = 1

Step-by-step explanation:

-To find the slope, you need the slope formula:

$m=\frac{y2-y1}{x2-x1}$ where you have $(x1,y1)$ and $(x2,y2)$ on the equation.

-Next, you put the two points to the equation:

$m=\frac{1+3}{1+3}$

-And then you solve the equation:

$m=\frac{1+3}{1+3}$

$m=\frac{1+3}{1+3} = \frac{4}{4}=1$

$m=1$

Rose and Dennis each open a savings account at the same time. Rose invests $2,600 in an account yielding 4.1% simple interest, a

vodka [1.7K]

The formula is
A=p (1+rt)
A future value
P present value
R interest rate
T time in years

Rose investment
A=2,600×(1+0.041×9)
A=3,559.4

Dennis investment
A=2,200×(1+0.057×9)
A=3,328.6

So Rose investment is greater than Dennis investment by
3,559.4−3,328.6=230.8

Hope it helps!
