Answer:

-4x-3y=1

Step-by-step explanation:

when adding the wo equations, u must add like ters. -2x+-2x is -4x. and positive y+ -y= -3y and-5+6=1. so if u put it all together after adding all integers you get -4x-3y=1

Answer: 5y = -11

Step-by-step explanation:

-2x + y = -5

(-2x - 4y = 6) -1

-2x + y = -5

2x + 4y = -6

System by elimination method

0 + 5y = -11

5y = -11

If a rectangle has a base of 6 units, and a height of 8 units, what is its area?
Morgarella [4.7K]

Answer:

a=48 units^2

Step-by-step explanation:

The area of a rectangle can be found using:

a=bh

We know the base is 6, and the height is 8, so we can substitute them in

a=6*8

a=48

Area uses units squared, so,

a=48 units^2

Prime factorization practice all factors 1.- 25 2.- 49 3.- 7 4.- 13 5.- 24 6.- 48 7.- 168
sergiy2304 [10]
I'll do the first 2 and 6, and I challenge you to do the other three on your own!

For 1, from some guess and check we can figure out that 5*5=25. Since 5 is a prime number, that's it!

For 2, we can figure out that 7*7=49 and 7 is a prime number, so we're good there.

From 6, we can do some guess and check to figure out that 2*24=48, 2*12=24, 2*6=12, and 2*3=6, resulting in 2*2*2*2*3=48 since 2 and 3 are prime numbers. We found out, for example, to find 2*12 due to that if 2*24=48, 2*24 is our current factorization. By finding 2*12=24, we can switch it to 2*2*12

The following two sets of parametric functions both represent the same ellipse. Explain the difference between the graphs.
statuscvo [17]
The answer
ellipse main equatin is as follow:

X²/ a²   +  Y²/ b²  =1, where a≠0 and b≠0

for the first equation: <span>x = 3 cos t and y = 8 sin t
</span>we can write <span>x² = 3² cos² t and y² = 8² sin² t
and then  </span>x² /3²= cos² t and y²/8² =  sin² t
therefore,  x² /3²+ y²/8²  =  cos² t + sin² t = 1
equivalent to x² /3²+ y²/8²  = 1

for the second equation, <span>x = 3 cos 4t and y = 8 sin 4t we found
</span>x² /3²+ y²/8²  = cos² 4t + sin² 4t=1
