Answer:

D) (14.10)

Step-by-step explanation:

2x -3y= -2

2. (x-y=4)2

(2x -3y= -2) 1

3. 2x-2y=8 (equation 1)

2x-3y =-2 (equation 2)

4.subtract equation 2 from equation 1 to eliminate x

5. y= 10

6. use either of the initial equations to find x eg.

x-y = 4

x- 10= 4

x = 10 + 4

x= 14

therefore x,y = 14,10

Answer:

Step-by-step explanation:

barrier = parameter, so we add all the sides:

8+3+3+5+5 = 24

24*1.75 = $42.

THEN, we need the area to solve for the mulch.

I would split it up into two parts so the rectangle and then the triangle.

First, 8*3 is 24

now we divide this by four because one bag covers four square feet

so, 6 bags (24/4=6) which is $36 (6*$6).

_______________

Now, the triangle, which a = (hb*b)/2

12 divided by four again so 3

3 * 6 = $18.

Now we add ALL costs up to get

42+36+18 = $96 total for the entire project.

Sherrie's method will make more money.

Step-by-step explanation:

They both deposit 300 dollars, since Harrison is compounding at 5% quarterly she will be making $15 every quarter and since there are 4 quarters per yr at the end of the year Harrison will be sitting at $360.

Whereas Sherrie is compounding at 3% per month so she will be making $9 per month and multiply that by 12 she will be sitting at $408 by the end of the year hence Sherrie makes more.

Answer:

12 pints

Step-by-step explanation:

There are 24 students & each one gets 1 cup, so you will need 24 cups total.  There are 2 cups in a pint.  You divided the 24 cups you need by 2 cups in a pint to get the answer of 12 pints.

You can double check:  12 pints converted to cups (2 cups in a pint) is 12 x2 = 24 cups

Answer: True

Step-by-step explanation:

It passes the vertical line test, no two points are on the same x value

Correct option is A .True . The given graph is of a function by vertical line test

The vertical line test is a test that checks whether a  given graph is of a function or not. It states that every vertical line passing through the given graph should intersect the graph at most one point .( which comes from the definition of function that that a function takes every point in the input set to a unique image in the codomain set)

For the given graph whenever we will draw a vertical line passing through any point on the domain then it will cut the graph at one point only this can be seen in the attached figure.

Therefore, its true that the given graph represents a function.

∴Correct option is A. True.

Answer:

[tex]y = -\frac{1}{2} x - 3[/tex]

Step-by-step explanation:

Answer:

f(x) = -1/2x - 3.

Step-by-step explanation:

The slope of the line = ((-7 - -5) / (8 - 4)

= -2/4

= -1/2.

y - y1 = m(x - x1)

m = -1/2, x1 = 8 and y = -7 so:

y - (-7) = -1/2(x - 8)

y + 7 = -1/2x + 4

y = -1/2x - 3.

A percentage is a way to describe a part of a whole.  The most improbable simulation for this coin is heads are 9.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

The most improbable simulation for this coin for heads is the frequency of heads coming up out of 20 which is far from the estimated frequency. Since out of these 20 times 75% of the times the head will come up. Therefore, the number of times the head will come up can be written as,

[tex]75\%\ of\ 20\\\\= \dfrac{75}{100} \times 20\\\\= 15[/tex]

Now it is estimated that at least 15 times out of 20, the head will come up. Thus, the most improbable simulation for this coin is heads are 9.

Step-by-step explanation:

Answer:

Below in bold.

Step-by-step explanation:

The formula for the number of degrees in a convex polygon of side length n is   S = 180(n - 2)

Solving for n:

n - 2 = S/180

and  n = (S/180) + 2.

1.   n = (900/180) + 2 = 5 + 2 = 7 . This is a heptagon.

2.   n = (1800/180) + 2 =  12.  A duodecagon.

3.   n = (2160/180) + 2 =   14 sided polygon.

4.    n =  (2520/180) + 2 = 16 sided polygon.

5.    n = (3420/180) + 2 =  21 sided polygon.

The number of the lions that live in the region investigated by the considered scientist is 80.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For this case, we're specified that:

Let we take:

x = number of lions the scientist located and tagged on thursday.

Then, we get:

x - 10 = number of lions the scientist located (and assumingly found that they're tagged) on friday,

4 = number of lions he found tagged on friday.

That means, x -10 is same number as 4

or, we get:

[tex]x - 10 = 4\\\text{Adding 10 on both the sides}\\\\x = 14[/tex]

That means, on thursday, the scientist located and tagged 14 lions.

Now, suppose that the region had 'y' number of lions,

Then, as per the data in the question,

one-fifth of y =  number of lions located by scientist on thursday

or, we get:
[tex]\dfrac{y}{5} = x\\\\\dfrac{y}{5} = 14\\\\\text{Multiplying 5 on both the sides}\\\\y = 80[/tex]

Thus, the number of lions that live in the region considered is 80

The total number of lines is 70.

We have given that,

A scientist wants to estimate the number of lions living in a region.

On Thursday, he locates and tags some lions.

On Friday he returns and locates 10 less lions than he had on Thursday.

He notices that 4 of the lions are tagged

The scientist works out an estimate for the total number of lions living in the region.

we have to determine the no of lines in the length.

on Thursday no.of lines=x

on friday=(x-10)=4

x-10=4

add like terms

Like terms are terms whose variables and their exponents such as the 2 in x^2 are the same.

x=10+4

x=14

No.of total lions =5th of (no. of tagged on Thursday.)

=5(14)

=70

Therefore the total number of lines is 70.

Using proportions, it is found that he should collect 80 signatures in each week.

A proportion is a fraction of a total amount.

He currently has 520 signatures, and needs 1000, hence he needs to collect more 1000 - 520 = 480 signatures.

He has six weeks to collect the signatures, hence the number he needs to collect each week is given by:
