HELP IMPORTAINT!! Part A and B quick!!!​

Answer:

b

Step-by-step explanation:

The solution of the equations 3x + 2y = 13 y = x - 1 will be (3, 2). Then the correct option is B.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The equations are given below.

3x + 2y = 13 ...1

y = x - 1 ...2

Then from the equations 1 and 2, we have

3x + 2(x - 1) = 13

        5x - 2 = 13

             5x = 15

               x = 3

Then the value of y will be

y = x - 1

y = 3 - 1

y = 2

Answer:

3/11

Step-by-step explanation:

First, determine how many dogs are at the boarding service:

2+8+22+12 = 44

Then:

# of Dobermans          12

--------------------------  =  ------- = 6/22 or 3/ 11

     total # of dogs         44

The desired ratio is 3/11.

It would B. 9.

Reason to this is because the radius is outlined by line GL. GL is half of the diameter which is GJ.

The answer is B. 9 because GJ is the circumference of the circle and they’re basically asking you to find the radius and the radius is half the circumference and half of 18 is 9 so the answer would be B.

Answer:

The graph is as attached.

Step-by-step explanation:

Simply draw a line of x = 2 on your graph paper.

That line should be a complete line not dotted line.

Since x is greater than 2, shade the left side of the line because we are interested in the right side (where x is greater and equal to 2)

Answer:

Here, the given inequality,

[tex]x\geq 2[/tex]

Related equation is,

x = 2

Which is the equation parallel to y-axis and passes through (2,0),

Also, 0 ≥ 2 ( False )

The shaded region of the inequality will not contain the origin,

Now, '≥' shows the solid line.

Thus, by the above explanation,

We can graph the given inequality ( shown below )

EXPLANATION

The frequency of a wave function refers to the number of times the graph repeats its cycle within the interval [0,2π]

We can observe explicitly from the graph that the frequency is half.

The period of the given function is 4π

[tex] \frac{2\pi}{b} = 4\pi[/tex]

[tex]b = \frac{2\pi}{4\pi} = \frac{1}{2} [/tex]

Hence the frequency is half.

The solution of the inequality {5x < 9521} is given by the inequality → x < 1904.2.

An inequality is used to compare two or more expressions or numbers.

For example -

2x > 4y + 3

x + y > 3

x - y < 6

Given is to find the solution set of the inequality →

5x < 9521

The given inequality is -

5x < 9521

Dividing by {5} on both sides, we get -

(5x/5) < (9521/5)

x < 1904.2

Therefore, the solution of the inequality {5x < 9521} is given by the inequality → x < 1904.2.

Answer:

12/5

Step-by-step explanation:

I doubt that you actually meant If cos0= -5/13 and sin 0<0.  Please use a Greek letter, such as Ф, to represent the angle.

If you'd do this, you'd have:

If cosФ= -5/13 and sin Ф<0

cos Ф and sin Ф are both negative in Quadrant III.

Recall that cos Ф = adj / hyp, and that hyp is always +.  Thus, adj = -5 and hyp = +13.  Using the Pythagorean Theorem to find opp:

opp² + adj² = hyp², or:

opp² = hyp² - adj².  Applying this, we find that opp = -12.

Recall that tan Ф = opp / adj.

Here,

tan Ф = -12 / (-5) = +12/5

Coefficients (in BOLD) : 3x+10

one coefficient

Constants (in BOLD) : 3x+10

Step-by-step explanation:

Terms are the contents in the equation of such. For example, 10+4n. There are two terms. Coefficients are the number next to a variable. For example, 9x. 9 is the coefficient. Constants are numbers without a variable. Numbers like 7, 8, 9, 10-- they don't have variables so they are constants in an equation. Now, knowing this information lets get to work!

Final answer:

The expression 3x+10 consists of two terms: 3x (with the coefficient 3) and 10 (the constant).

Explanation:

In the expression 3x+10, there are two terms: 3x and 10. The term 3x consists of a variable (x) and a coefficient (3), which is the number multiplying the variable.

The term 10 is a constant because it does not contain any variables and its value does not change. The coefficients in this expression are therefore the number 3, and the constant is 10.

The answer to this is:

B. 190

The sum of the first 10 terms of the sequence an=4n-3 is 190.

The question is asking for the sum of the first 10 terms of the sequence defined by an=4n-3. To find the sum, we first list the first 10 terms by substituting values of n from 1 to 10 into the formula. Thus, for n=1, a1=1(4)-3=4-3=1; for n=2, a2=2(4)-3=8-3=5; and so on until n=10, a10=10(4)-3=40-3=37.

The first ten terms of the sequence are: 1, 5, 9, 13, 17, 21, 25, 29, 33, and 37. The sum of these terms can be calculated as 1+5+9+13+17+21+25+29+33+37 = 190.

Answer:

  Initially, the tundra has 180 caribou, and every year , the number of caribou increases by a factor of 1.2 .

Step-by-step explanation:

"Initially" generally means "when t=0." Put 0 where t is in the function and evaluate it:

  f(0) = 1.8(1.2)^0 = 1.8(1) = 1.8 . . . . . hundreds

1.8 hundreds is 1.8×100 = 180.

__

t is in years, so the simplest choice for the second blank in the statement is "year".

__

The exponent of 1.2 is t, which means that 1.2 is a factor of the expression the number of times specified by t.

  for t=0, f(0) = 1.8

  for t=1, f(1) = 1.8(1.2)

  for t=2, f(2) = 1.8(1.2)(1.2)

  for t=3, f(3) = 1.8(1.2)(1.2)(1.2)

Perhaps you can see that every year, the number increases by a factor of 1.2.

In order to find out the total number of crayons, you multiply the number of cases by the number of boxes per case, and then by the number of crayons per box. Assuming the store donated 5 cases, the daycare center received a total of 960 crayons.

To determine how many crayons the daycare center received from the store, we need to multiply the number of cases the store donated by the number of boxes in each case, and then multiply that by the number of crayons in each box. Let's break it down step by step:

Assuming the store donated 5 cases (the number of cases was not specified in the question, so we need to assume a number for this example), here's how you would calculate it:

Therefore, the daycare center received a total of 960 crayons.

x = -5/7

Step-by-step explanation:

8               1

---------- = ----------

x+3           x+1

Using cross products

8 (x+1) = 1 (x+3)

Distribute

8x+8 = x+3

Subtract x from each side

8x-x +8 = x-x+3

7x+8 =3

Subtract 8 from each side

7x +8-8 =3-8

7x = -5

Divide each side by 7

7x/7 = -5/7

Answer:

The chef would need 5 bags

Step-by-step explanation:

Because 3 times 5 equals 15

To determine the number of bags of flour the chef should buy, divide the total weight required (15 lb) by the weight of one bag (3 lb), resulting in the need to purchase 5 bags.

To find out how many bags of flour the chef should buy, we need to divide the total weight of flour needed by the weight of one bag. If a bag weighs 3 lb, and the chef needs 15 lb, we calculate it as follows:

Determine the total weight needed: 15 lb.

Determine the weight of one bag: 3 lb.

Divide the total weight by the weight of one bag: 15 lb \/ 3 lb = 5 bags.

Therefore, the chef should buy 5 bags of flour to have a total of 15 lb.

Step-by-step explanation:

Answer:

81y^4 - 16x^2, difference of squares.

Step-by-step explanation:

So we need to expand the following product:

(9y2-4x)(9y2+4x) = 9y2*9y2 + 4x*9y2 - 4x*9y2 -4x*4x = 81y^4 - 16x^2

And this type of product is the difference of squares.

Answer:

Step-by-step explanation:

The given expression is ( 9y² - 4x) (9y² + 4x)

We will simplify the given expression

(9y² - 4x) (9y² + 4x) = 9y² (9y² + 4x) - 4x (9y² + 4x)  [Distributive property]

= 81y⁴ + 36xy² - 36xy² - 16x²

= (81y⁴ - 16x²)

This simplified form is the difference of squares of terms (9y²) and (4x)

Answer: [tex]10x^2+3xy+6x-y^2+3y[/tex]

Step-by-step explanation:

You need to remember the Product of powers property:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

Then, knowing this property, now you have to apply the Distributive property. So:

[tex](2x+y)(5x-y+3)=\\\\=(2x)(5x)-(2x)(y)+(2x)(3)+(y)(5x)-(y)(y)+(y)(3)\\\\=10x^2-2xy+6x+5xy-y^2+3y[/tex]

Finally, to simplify this expression, you need to add the like terms.

Therefore, you get that the product is:

[tex]=10x^2+3xy+6x-y^2+3y[/tex]

Answer:

10 3 6 -1 3

Step-by-step explanation:

Answer:

p = 8

Step-by-step explanation:

Subtract 18 from behind the equal sign to cancel it out. This leaves you with 2(p+1)- 18= 0.

Next you'll need to pull out the terms to work with the beginning of the problem. 2(p+1)- 18= 0 would turn into 2p - 16  = 2(p - 8).

This would leave you with 2= 0, but that's not true so continue on to the variable.

So p - 8= 0 making the answer p = 8
