Step-by-step explanation:

Answer:

(1,1)

Step-by-step explanation:

3x + 2y = 5

4x − 9y = −5

Multiply the first equation by 4 and the second equation by -3 so we can eliminate x

4(3x + 2y) = 5 *4

Distribute

12x +8y = 20

-3(4x − 9y) = −5*-3

-12x +27y = 15

Add the two new equations together

12x +8y = 20

-12x +27y = 15

------------------------

35y = 35

Divide by 35

35y/35 = 35/35

y=1

Now we can find x

3x+2y =5

3x+2(1) =5

3x +2 =5

Subtract 2 from each side

3x+2-2=5-2

3x=3

Divide by 3

3x/3 = 3/3

x=1

Answer:

d

Step-by-step explanation:

To determine if (1, 2) is a solution to the system

Substitute x = 1, y = 2 into the inequalities and check their validity.

y > 2x → 2 > 2 ← incorrect statement

x + y < 3

1 + 2 < 3 → 3 < 3 ← incorrect statement

(1, 2) is not a solution to either inequality → d

1) What are the zeros of the function?

smaller r: -11, larger r: -14

2) What is the vertex of the parabola

Vertex: (-12.5, 3)

1. Zeros:

The zeros of the function occur when G(r) = 0. So we need to solve the equation:

-(r + 11)(r + 14) = 0

Since the product of two factors is zero when one or both factors are zero, we can set each factor equal to zero and solve for r:

r + 11 = 0 --> r = -11 (smaller r)

r + 14 = 0 --> r = -14 (larger r)

2. Vertex:

The function is given in factored form, which makes finding the vertex a bit easier. The vertex of a parabola in factored form is exactly between the two zeros.

Therefore, the x-coordinate of the vertex is:

(smaller r + larger r) / 2 = (-11 - 14) / 2 = -12.5

To find the y-coordinate (i.e., the function's value at the vertex), we can plug the x-coordinate of the vertex back into the function (G(r)). However, since the function is multiplied by -1, it might be easier to use one of the original zeros (say, r = -11).

G(-11) = -(-11 + 11)(-11 + 14) = 3 (notice how the negative sign cancels out)

Step-by-step explanation:

Download song .50

Download album = 4

Let s = number of songs

a = number of albums

She can spend 15 dollars

.5s +4a =15

If she downloads 6 songs, let s=6

.5(6) +4a = 15

3+4a = 15

Subtract 3 from each side

3-3+4a = 15-3

4a = 12

Divide by 4

4a/4 =12/4

a=3

She can buy 3 albums

If she downloads 1 album, let a=1

.5(s) +4(1) = 15

.5s +4=15

Subtract 4 from each side

.5s +4-4=15-4

.5s = 11

Divide by .5

.5s/.5 = 11/.5

s = 22

She can download 22 songs

If she downloads 30 songs, let s=30

.5(30) +4a = 15

15+4a= 15

Subtract 15 from each side

15-15 +4a = 15-15

4a=0

a=0

Answer:

The correct answer is option B.

Step-by-step explanation:

The given rational expression is:

[tex]\frac{x^2-4}{x^2+5x+6}[/tex]

Factor the numerator and the denominator:

[tex]\frac{x^2-2^2}{x^2+2x+3x+6}[/tex]

Factor the numerator using difference of two squares and the denominator using factorization by grouping.

[tex]\frac{(x-2)}{x(x+2)+3(x+2)}[/tex]

[tex]\frac{(x-2)(x+2)}{(x+2)(x+3)}[/tex]

This function is defined if and only if the denominator is not zero.

That is: (x+3)(x+2)≠0.

x≠-2,x≠-3

We simplify now to obtain:

[tex]\frac{x-2}{x+3}[/tex]

The correct choice is the second option.

Option B is correct.

Answer:

The probability your mean age will be at least 28 is 83%

Step-by-step explanation:

Let X denote the ages of all new employees hired during the last 10 years , then X is normally distributed with;

a mean of 31

a standard deviation of 10.

The sample size obtained is 10 employees. This implies that the sampling distribution of the sample mean will be normal with;

a mean of 31

a standard deviation of [tex]\sqrt{10}[/tex]

The sample mean is a statistic and thus has its own distribution. Its mean is equal to the population mean, 31 and its standard deviation is equal to [tex]\frac{sigma}{\sqrt{n} }[/tex]

where sigma is the population standard deviation, 10 and n the sample size which in this case is 10. [tex]\frac{10}{\sqrt{10} }=\sqrt{10}[/tex]

We are required to find the probability that this sample mean age will be at least 28;

P(sample mean ≥ 28)

Since we know the distribution of the sample mean we simply standardize it to obtain the z-score associated with it;

P(sample mean ≥ 28)

= [tex]P(Z\geq \frac{28-31}{\sqrt{10} } )=P(Z\geq -0.9487)[/tex]

=0.8286

As a percentage this is equivalent to, 83%

C) Given the radius or the diameter, you can calculate the area of the base of a cylinder - Yes as the area is [tex]\pi r^{2}[/tex] where 'r' is the radius.

D) The height of a cylinder is the distance between the 2 parallel bases. Yes this is right.

Congruent is the same size and same shape. When a ray bisects an angle, the two newly created angles will be congruent, since the ray went right in the middle of the first angle (so in this case, ABC and DBC will be congruent)

Answer: C) ∠ABC & ∠DBC

Step-by-step explanation:

When a ray bisect an angle , then it divided the original angle into two congruent angles.

We are given that Ray BC bisects angle ABD.

Then, Ray BC divides ∠ABD into two congruent angles.

From the picture, The angle formed by it : ∠ABC & ∠DBC

So  ∠ABC & ∠DBC must be congruent.

Hence, the pair of angles must be congruent : ∠ABC & ∠DBC

The coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

Suppose we've two endpoints of a line segment as A(p,q), and B(m,n), then let the midpoint be M(x,y) on that line segment. Then, its coordinates are x =(p+m)/2 and y = (q+n)/2.

Given the endpoints of the line segment are A(-3,4) and B(-6,-1), then the coordinates of the midpoint will be,

x = (2+10)/2 = 12/2 = 6

y = (3+3)/2 = 6/2 = 3

Hence, the coordinates of the midpoint of the line segment that has endpoints (2,3) and (10,3) are (6,3).

Answer:

perimeter = 10x + 2

area = 6x^2 + 2x

perimeter = 52

area = 160

Step-by-step explanation:

perimeter = 2 * length + 2 * width

perimeter = 2(3x + 1) + 2(2x)

perimeter = 6x + 2 + 4x

perimeter = 10x + 2

area = length * width

area = (3x + 1)(2x)

area = (2x)(3x + 1)

area = 6x^2 + 2x

For x = 5:

perimeter = 10x + 2 = 10(5) + 2 = 50 + 2 = 52

area = 6x^2 + 2x = 6(5^2) + 2(5) = 6(25) + 10 = 150 + 10 = 160

2 > -3     (2 is greater than -3, this is true)

-7 < -5    (-7 is less than -5, this is true because -7 is more negative than -5)

-9 < 1       (-9 is less than 1, this is true)

0 < -4      (0 is less than -4, this is false because 0 is greater than -4)

Among the comparisons given, "0 < -4" is incorrect.

The student is asking which comparison is not correct. After evaluating each comparison, it becomes clear that 0 < -4 is not correct because 0 is not less than -4; in fact, 0 is greater. Other comparisons such as 2 > -3, -7 < -5, and -9 < 1 are all correct, as in each case, the number on the left side of the inequality is indeed larger (or smaller, for negative numbers) than the number on the right side as the symbol indicates.

To understand why 0 < -4 is incorrect, consider the number line where any number to the right is greater than the number to the left. Zero (0) lies to the right of any negative number, including -4, which means it is greater, not less.

Answer:

x² + 2x + [3\x - 1]

Step-by-step explanation:

Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

1| 1 1 -2 3

↓ 1 2 0

------------------

1 2 0 3 → x² + 2x + [3\x - 1]

You start by placing the c in the top left corner, then list all the coefficients of your dividend [x² + 5x - 36]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder, which in this case is a 3, so what you is set the divisor underneath the remainder of 3. Finally, your quotient is one degree less than your dividend, so that 1 in your quotient can be an x², 2 becomes 2x, and the remainder of 3 is set over the divisor, giving you the other factor of x² + 2x + [3\x - 1].
