How many solutions does this system have?Y = x + 5
Y = -5x – 1
A) One
B) None
C) Infinite
D) Two

Answers

Answer 1

Answer: Well this does take some work on scratch paper but ill let you know that we have to plug these in to make one whole big equation
lets do that!
x + 5 = -5x - 1 now add +1 to both sides of the equation
+ 1 = +1 it cancels out on the right side and we solve on the left
*****************
x + 6 = -5x Now lets subtract that(1x) from both sides
-1x = -1x ( if x stands alone, theres always an imaginary 1 right by it)
************** now -5 - 1 = -6 so its -6x
6 = -6x Now divide both sides by -6 to isolate x to be alone
÷-6 = ÷6 It cancels out on the right side and we solve on the left
************ 6 ÷ -6 = 0 so lets see what we have
0 = x
Since zero is still a number this means there is only 1 solution!
Answer = A.) one
I hope this helps!
and dont forget 2

The ratio of the smaller to the larger is 3:9. That can also be written as a fraction, $(3)/(9)$ , which of course can be reduced to $(1)/(3)$ or 1:3. That's your ratio.

The number of roses (r) in a garden increases when the number of weeds (w) decreases. Write the correct equation for this scenario, and solve for the number of roses when there are 5 weeds.Weeds Roses
10 20
20 10

Answers

Number of roses (r) in a garden increases when the number of weeds (w) decreases, this supports an inverse relationship between the two variables.
The formula is then therefore, r = k/w
Solve for constant first.
r = k/w
20 = k/10
200 = k

r=200/5
r=40 roses
40 roses when there are 5 weeds.

Answer:

The Inverse variation says that:

$y \propto (1)/(x)$ ,

then the equation is of the form:

$y = (k)/(x)$ or $xy = k$

Here, r represents the number of roses and w represents the number of weeds.

As per the statement:

The number of roses (r) in a garden increases when the number of weeds (w) decreases.

by definition of inverse variation:

$rw = k$ ....[1]

From the given table:

take any points

r = 20 and w = 10 then;

Substitute in [1] we have;

$(20)(10)= k$

Simplify:

k = 200

The equation becomes: $rw = 200$

We have to find the number of roses when there are 5 weeds.

⇒w = 5

then;

$r(5) = 200$

Divide both sides by 5 we get;

r = 40

Therefore, the number of roses are 40 when there are 5 weeds.

How do you simplify the square root of 48

Answers

When you simplify the square root of a number, you are looking for factors of the number that are perfect squares that you can remove from under the radical. For example sq root of 8... it's not a perfect square but factors of 8 include 2 x 4... 4 is a perfect square so we can take it out of the radical by taking it's square root. Now you are left with 2* sq root of 2.

For sq root of 48

48 = 12 x 4

12 = 3x4 so we can say 48 = 3x4x4

so... sq root 48 = sq root 3x4x4

we have two 4's under the radical. Sq root x^2 = x so sq root 4^2 is 4

Pull it out from the radical and we are left with 4 * sq root 3
