Answer:

A. x+1= 4x+5

Step-by-step explanation:

To solve the set of equation we can use substitution method.

Here the given set of equations are

Equation A : $y=x+1$

Equation B : $y=4x+5$

Now in substitution method we substitute y in terms of x from

first equation in to 2nd equation.

In other words we can also say that we equate both equations

so we have

$y=x+1 = 4x+5$

or we can also say that

$x+1= 4x+5$

hence the correct option is option A

Answer:

Step-by-step explanation:

y= x+1 at the same time y=4x+5

x+1= 4x+5, so answer is A

My sister needs help !!!!!!!

A coin has one of two outcomes: heads or tails.
Each has an equal probability of occurring, meaning that they each have a 50% chance to occur. (They need to add up to 100% because they include all the outcomes, divide that into two equal parts and...)

This is what we call theoretical probability. It's a guess as to how probability should work. Like in the experiment, it's not always going to be 50-50.

What actually happens is called experimental probability. This may vary slightly from theoretical probability because you can't predict probability with complete certainty, you can only say what is most likely to happen.

We want to find the probability of getting heads in our experiment so we can compare it to the theoretical outcome. To do this, we need to compare the number of heads to the total number of outcomes.

We have 63 heads, and a total of 150 coin flips.
That makes the probability of getting a heads 63/150.
The hard part is getting this ratio into a percent.

You can try simply dividing, but you should be able to notice something here.
SInce the top and the bottom of our fraction are both divisible by 3, we can simiplify.
63 ÷ 3 = 21
150 ÷ 3 = 50
So we could say that 63/150 = 21/50.

A percent is basically a fraction out of 100.
Just like you can divide the parts of a ratio by the same number and it will stay the same, you can also multiply. To get the fraction out of 100, let's multiply by 2.
(since 50 × 2 = 100)

21 × 2 = 42
50 × 2 = 100
21/50 = 42/100 = 42%

Comparing our experimental probability to the theoretical one...it is 8% lower.

3x+5y=-3 x-5y=-5 show your work

frez [133]

We are given the equations 3x+5y=-3 and x-5y=-5.

Both equations have a 5y term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.

3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8

The y terms cancel out since one is positive and one is negative. Now we can solve for x.

4x = -8

$\frac{4x}{(4)} = \frac{-8}{(4)}$

x = -2

Now plug -2 in for x in one of the original equations to find y.

(-2) - 5y = -5

-5y = -3

y = 3/5

Our answer as an ordered pair is (2, 3/5)
