Answers

Answer:

I think it is B sorry if it is wrong;-; have a good day

I believe B and D because a minus multiplied by a positive gives you a negative answer. Therefore, your answer would equal to -36.

Answer:

b = 3

Step-by-step explanation:

Use the table to find the slope and y-intercept

Find the slope:

m = (6 - 4)/(3 - 1) = 2/2 = 1

Find b using the pair (1, 4):

Step-by-step explanation:

i hope that this is what you are looking for^_^

This is just a fancy way your teacher saying that when you have an equation y=[tex]4^{x}[/tex]+1, what is y when x=-1,0,3.

We just need to solve by substituting the x in respectively.

x=-1, y=[tex]\frac{5}{4}[/tex]

x=0, y=1

x=3, y=65

Which method would be best (quickest) for solving the system below:
3x - 4y = -2
y = 2x + 1

Answers

To solve with Elimination:

Write the equations under one another, like this:

2x - y = -1
+ 3x + 4y = 26

Ideally, we would like for one of the variables to be eliminated when we add vertically (straight down). But if we add them as they are this does not happen. We must manipulate one of the equations so that it will happen. Again, you can try to eliminate either x or y. I always look for a term that has a coefficient of 1 (or negative 1). So, let's use that y from the first equation again.

If the coefficient of the y in the other equation is POSITIVE 4, then I need the coefficient from the first equation to be its opposite, NEGATIVE 4. To do this, simply multiply the first equation by 4, this will create MAGIC!

4( 2x - y = -1)
+ 3x + 4y = 26

Be certain to Distribute across the entire first equation, so multiply all three terms by 4.

8x - 4y = -4
+ 3x + 4y = 26

Now add straight down (vertically). The y term will be eliminated.

11x = 22

Divide both sides of the equation by 11.

x = 2

Almost there! Now, substitute the 2 in for x in either of the original equations. Either one will work. I'm gonna use the second equation.

3x + 4y = 26

3(2) + 4y = 26

6 + 4y = 26

Subtract 6 from both sides of the equation.

4y = 20

Divide both sides of the equation by 4.

y = 5

That's it! There it is again. Put it all together. If x = 2 and y = 5, then the solution is the ordered pair, (2,5).

Peter works two part time jobs. He is paid $6 er hour at job a and $9 per hour at job b. Last wee eter worked a total of 24 hours at both jobs and madr $189. Hobmny hours dud peter work at job a?

Answers

Answer: Peter worked 9 hours at job a

Step-by-step explanation:

Step 1

Let the number of hours worked in  job a = x

and number of hours worked in job b = y such that the total hours worked would be expressed as

x=y= 24 ---eqn 1

also since $6 and $9 dollar are paid per hour for the job  and the total amount made is $189, it should be expressed as

6x + 9y =$189--- equation 2

Step 2

Now we have gotten two expressions to solve for number of hours, we can now solve

x+y= 24 ---eqn 1

6x + 9y =$189--- eqn 2

Using elimination method, we multiply equation 1 by 6 and subtract from equation 2

6x + 9y =189

-6x+6y=144

3y=45

y= 45/3 =15

To find x

x+y = 24

x+15=24

x= 24-15

x= 9

fff

Therefore Peter worked 9 hours at job a  and 15 hours at job b

How long will it take for a certain population of fish to triple if the relative growth rate is 45% per year?

Answers

Answer:

n = 3 Year (Approx)

Step-by-step explanation:

Given:

Growth rate (r) = 45% = 0.45

Find:

Number of year for 3 times of population (n)

Computation:

Assume;

Current population = P

So,

New population = 3P

A = p(1+r)ⁿ

3P = P(1+0.45)ⁿ

3 = (1.45)ⁿ

n = 2.96 year

n = 3 Year (Approx)

What is the value of expression below -8.125 + 7 3/8

Answers

Answer:-6/8, -3/4, -0.75

Step-by-step explanation:

Background info:

0.125=1/8

An you can also use the commutative property to "flip" the equation

Let's rewrite -8.125 as 8 1/8 because we know 1/8=0.125

And let's write it as a improper fraction - 65/8 and let's write 7 3/8 too as 59/8

Now we have to use the distributive property and subtract 65/8 from 59/8 (59/8 - 65/8) and you will get -6/8 or simplified -3/4 or in decimal -0.75
