Does This Graph Show A Function?

Answers

Answer 1

9514 1404 393

Answer:

  A

Step-by-step explanation:

A vertical line intersects the graph in more than one place. As a consequence, we say the graph "fails the vertical line test." When the test fails, the graph is not a graph of a function.

find hcf of 3x²+7x-6 and 2x²+7x+3​

Answers

Given:

The expression are:

[tex]3x^2+7x-6[/tex]

[tex]2x^2+7x+3[/tex]

To find:

The HCF of the given expression.

Solution:

We have,

[tex]3x^2+7x-6[/tex]

[tex]2x^2+7x+3[/tex]

The factor form of given expressions are:

[tex]3x^2+7x-6=3x^2+9x-2x-6[/tex]

[tex]3x^2+7x-6=3x(x+3)-2(x+3)[/tex]

[tex]3x^2+7x-6=(x+3)(3x-2)[/tex]

Similarly,

[tex]2x^2+7x+3=2x^2+6x+x+3[/tex]

[tex]2x^2+7x+3=2x(x+3)+1(x+3)[/tex]

[tex]2x^2+7x+3=(x+3)(2x+1)[/tex]

From the factor forms it is clear that the factor [tex](x+3)[/tex] is common.

Therefore, the HCF of given expressions is [tex](x+3)[/tex].

x2 + 7y if x = -5 and y = -8

Answers

Answer:

x2 + 7y = -64 (if x = -5 and y = -8)

Step-by-step explanation:

x2 + 7y

(-5 × 2) + (7 × -8)

-10 + -54 which is the same as -10 - 54

-64

The value of expression x² + 7y at x = - 5 and y = - 8 is, - 31.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The expression is,

⇒ x² + 7y

And, x = - 5 and y = - 8

Now, Substitute the value of x and y in the expression, we get;

⇒ x² + 7y

⇒ (-5)² + 7×- 8

⇒ 25 - 56

⇒ - 31

Thus, The value of expression is, - 31.

Let X and Y be the following sets: X = {0, 12, 23} Y = {3, 12, 15) Which of the following is the set X/Y?​

Answers

Answer:

set X/Y = {0,23}

Step-by-step explanation:

We are given the sets;

X = {0, 12, 23}

Y = {3, 12, 15}

Now, we want to find the set X/Y.

The set X/Y means the set that has numbers which are only in set X but not in set Y.

The numbers from inspection of both sets are 0 and 23.

Thus;

set X/Y = {0,23}

Answers

Answer:

65 degrees

Step-by-step explanation:

I recently answered a question in detail that was similar to this one. Feel free to look at my answered questions for it.

For this one, the easiest way to think about it is this. The line on which both angle 4 and angle 1 sit is a straight line, that makes them supplementary angles which is just a fancy word that means if you add them together they equal 180.

(angle 4) + (angle 1) = 180

And if (angle 1) = 115, then that means

(angle 4) = 180 - 115

(angle 4) = 65

Nolan has some nickels and some dimes he has no more than 19 coins worth no less than $1.30 combined if Nolan has 5 nickels determine all possible values for the number of dimes that he could have

Answers

Answer:

10.5 ≤ y ≤ 14

Step-by-step explanation:

A nickel is worth 5 pennies. Changing over to dollars, it becomes  

5/100 = $0.05  

A dime is worth dime. Changing over to dollars, it becomes  

10/100 = $0.1  

Allow x to address the number if nickels.  

Allow y to address the quantity of dimes.  

He has close to 19 coins. This implies that  

x + y ≤ 19  

He has no under $1.30 joined. This implies that  

0.05x + 0.1y ≥ 1.3  

On the off chance that Nolan has 5 nickels, subbing x = 5 into x + y ≤ 19, it becomes  

5 + y ≤ 19  

y ≤ 19 - 5  

y ≤ 14  

subbing x = 5 into 0.05x + 0.1y ≥ 1.3, it becomes  

0.05 × 5 + 0.1y ≥ 1.3  

0.25 + 0.1y ≥ 1.3  

0.1y ≥ 1.3 - 0.25  

0.1y ≥ 1.05  

y ≥ 1.05/0.1  

y ≥ 10.5  

Along these lines, all potential qualities for the quantity of dimes that he could have would be  

10.5 ≤ y ≤ 14

Answers

Answer:

x = 25

Step-by-step explanation:

The two angles are supplementary

2x+5+5x = 180

7x+5 = 180 subtract 5 from both sides

7x = 175 divide both sides by 7

x = 25 to find the angle with the star replace x with 25

25*2 + 5 = 55

if the central angle is 3pie/4 and the radius is 13 what's the arc length

Answers

Answer:

The arc length is 9.75 pi units

Step-by-step explanation:

Mathematically, we use the formula below to get the length of an arc

Length of an arc is;

theta/360 * 2 * pi * r

where theta is the central angle

for 3pi/4 ; let us convert to degrees

The degree measure is 180 degrees for pi

so 3pi/4 will be (3 * 180)/4 = 135 degrees

So we have the arc length as follows;

135/360 * 2 * pi * 13 = 9.75 pi unit

- Select the equation that represents the area of the map in terms of x.
A)
A=x2


B)
A=2x+4


C)
A=4x2


D)
A=x(x+4)

Answers

Answer:

D)

A = x(x + 4)

Step-by-step explanation:

Area of a rectangular map = width × length

Length of the rectangular map = (x + 4) miles

Width of the rectangular map = x miles

Area of a rectangular map = width × length

= x(x + 4)

= x² + 4x

D)

A = x(x + 4)

Liam plays guitar in a band called Cool. The
band is paid $421.74 for every performance. If
Cool averages 3.5 shows per month, how much
money will the band earn in 3 months?

Answers

Answer: $4,428.27

Step-by-step explanation:

First you have to find out how many shows are in three months. If there is 3.5 shows in one month, multiply this by three to get the amount in 3 months.

3.5 x 3 = 10.5 shows

Now multiply the amount the band makes in one show by the number of shows.

$421.74 x 10.5 shows = $4,428.27 over the course of three months.

An emergency fund is defined as a savings account that has a balance equal to at least two months' living

To investigate this claim, a financial advisor selects a random sample of 150 American adults and finds that 112 do
not have an emergency fund. The financial advisor would like to know if the data provide convincing evidence that
the true proportion of Americans who do not have an emergency fund is less than 80%. What are the appropriate
hypotheses for this test?

Answers

Answer:

a H I o p=0.80 vs. Ha less than 0.80, where P equals the true proportion of All American adults who do not have an emergency fund

The appropriate hypotheses for this test are:

H0: p ≥ 0.80

Ha: p < 0.80

We have,

The appropriate hypotheses for this test are:

Null Hypothesis (H0):

The true proportion of Americans who do not have an emergency fund is equal to or greater than 80%.

Alternative Hypothesis (Ha):

The true proportion of Americans who do not have an emergency fund is less than 80%.

Symbolically, the hypotheses can be represented as:

H0: p ≥ 0.80

Ha: p < 0.80

Where p is the true proportion of American adults who do not have an emergency fund.

To determine whether the data provide convincing evidence against the null hypothesis,

We can conduct a hypothesis test using a significance level (alpha) of 0.05.

If the p-value is less than alpha, we can reject the null hypothesis and conclude that the true proportion of Americans who do not have an emergency fund is less than 80%.

Thus,

H0: p ≥ 0.80

Ha: p < 0.80 are the appropriate hypotheses for this test.
