{(0, 4), (2, 6), (4, 16)}
{(0, 4), (2, −6), (4, 20)}

Answers

ANSWER

{(0, −4), (2, 6), (4, 16)}

EXPLANATION

The given function is

[tex]y = 5x - 4[/tex]

when x=0,

y=5(0)-4

y=-4

(0,-4)

When x=2,

y=5(2)-4

y=6

(2,6)

When x=4

y=5(4)-4

y=16

(4,16)

The correct choice is

{(0, −4), (2, 6), (4, 16)}

Answer:

{(0, −4), (2, 6), (4, 16)}

Step-by-step explanation:

Since, in an order pair the first value represents the input value and second value represents the output value,

i.e. (a, b) is an order pair ⇒ a = input, b = output,

Here, the given function,

[tex]y = 5x - 4[/tex]

(i) For the relation {(0, −4), (2, 6), (4, 20)},

At ( 4, 20), y = 5(4) - 4 = 20 - 4 = 16 ( false ),

(ii) For the relation {(0, −4), (2, 6), (4, 16)},

At (0, −4), y = 5(0) - 4 = -4 ( true ),

At (2, 6), y = 5(2) - 4 = 10 - 4 = 6 ( true ),

At ( 4, 16), y = 5(4) - 4 = 20 - 4 = 16 ( true ),

(iii) For the relation {(0, 4), (2, 6), (4, 20)},

At (0, 4), y = 5(0) - 4 = -4 ( false ),

(iv) For the relation {(0, 4), (2, −6), (4, 20)}

At (2, -6), y = 5(2) - 4 = 6 ( false ),

Hence, (ii) represents possible inputs and outputs of the function.

What are the coordinates of the endpoints of the mid segment for ABC that is parallel to Bc?

ANSWER ASAP PLEASE !!

Answers

Answer:

(4,2) and (8,2)

Step-by-step explanation:

The mid segment unites the middle of two sides of a triangle.  In this case, the question wants us to have it parallel to BC, so it has to unite the middle of AB to the middle of AC.

The use of the clear grid in this case makes that we don't have to use any angle calculation.

If you start from point B, you'll need to go 6 units to the right and 8 units up to meet with A. That means the center point is located 3 units right and 4 units high from point B... so, we have point (4,2).

Starting from C, we do a similar calculation.  you need to go 2 units to the left and 8 units up... so the mid-point is 1 unit to the left and 4 units up... so (8,2).

If m(x)=x+5/x-1 and n(x) = x – 3, which function has the same domain as (m.n)(x)

Answers

Final answer:

The function m(x) = x + 5/(x-1) has the same domain as the composition of functions (m.n)(x) because they both have the domain of all real numbers except 1.

Explanation:

The domain of a function is the set of all possible input values (often called 'x-values') which will give valid output values. In other words, it's all the values x can take on. The function m(x) = x +5/(x-1) will be undefined when the denominator equals zero, so x cannot equal 1. Therefore, the domain of m(x) is all real numbers except 1.

On the other hand, the function n(x) = x - 3 doesn't have any restrictions and can take on all real numbers. However, (m.n)(x) refers to a composition of functions, specifically m(n(x)). This will inherit the domain restrictions from m(x). Therefore, the function that has the same domain as (m.n)(x) is m(x) because the composition will allow inputs for all real numbers except 1, as dictated by m(x).

Let f(x)=x^2+5x-8. What is the average rate of change from x = 2 to x = 6? Enter the answer in the box ___

please show the work and answer

Answers

Answer:

13

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

Here [ a, b ] = [2, 6 ]

f(b) = f(6) = 6² + 5(6) - 8 = 36 + 30 - 8 = 58

f(a) = f(2) = 2² + 5(2) - 8 = 4 + 10 - 8 = 6

Hence

average rate of change = [tex]\frac{58-6}{6-2}[/tex] = [tex]\frac{52}{4}[/tex] = 13

Final answer:

The average rate of change of the function f(x) = x^2 + 5x - 8 from x = 2 to x = 6 is calculated to be 13.

Explanation:

The average rate of change of a function f(x) from x = a to x = b is found by the formula Δf / Δx = (f(b) - f(a)) / (b - a). In this case, we have f(x) = x^2 + 5x - 8, and we want to find the average rate of change from x = 2 to x = 6.

Calculate f(2) = 2^2 + 5(2) - 8 = 4 + 10 - 8 = 6.Calculate f(6) = 6^2 + 5(6) - 8 = 36 + 30 - 8 = 58.Apply the average rate of change formula: (f(6) - f(2)) / (6 - 2) = (58 - 6) / (4) = 52 / 4 = 13.

Therefore, the average rate of change of the function from x = 2 to x = 6 is 13.

Solve this system of linear equation. Supérate the x- and y-values with a comma. 2x+4y=-48 4x-9y=57

Answers

Answer:

(x,y) = (-6.12,-11.76)

Step-by-step explanation:

2x+4y=-48 => eq(i)

4x-9y=57  => eq(ii)

We need to solve these equations simultaneously to find the values of x and y.

Multiplying eq(i) with 2 and subtracting both equations

4x + 16y = -96

4x - 9y  = 57

-    +         -

__________

25 y = -153

y = -153/25

y = -6.12

Putting value of y in eq(i)

2x + 4(-6.12) = - 48

2x - 24.48 = -48

2x = -48 + 24.48

2x = -23.52

x= -23.52/2

x= -11.76

So, values of x and y are -6.12 and -11.76

(x,y) = (-6.12,-11.76)

The solution to the system of linear equations is [tex]\(x = -6\) and \(y = -9\).[/tex]

Let's solve the system of linear equations:

[tex]1. \(2x + 4y = -48\)\\2. \(4x - 9y = 57\)[/tex]

We can use the substitution or elimination method. I'll use the elimination method here:

Multiply the first equation by 2 to make the coefficients of [tex]\(x\)[/tex]in both equations the same:

[tex]1. \(4x + 8y = -96\)\\2. \(4x - 9y = 57\)[/tex]

Now, subtract the second equation from the first to eliminate [tex]\(x\):[/tex]

[tex]\((4x + 8y) - (4x - 9y) = -96 - 57\)[/tex]

Simplify:

[tex]\(17y = -153\)[/tex]

Now, solve for \(y\):

[tex]\(y = -\frac{153}{17} = -9\)[/tex]

Now that we have \(y\), substitute it back into one of the original equations. I'll use the first equation:

[tex]\(2x + 4(-9) = -48\)[/tex]

Simplify:

[tex]\(2x - 36 = -48\)[/tex]

Add 36 to both sides:

[tex]\(2x = -12\)[/tex]

Divide by 2:

[tex]\(x = -6\)[/tex]

So, the solution to the system of linear equations is [tex]\(x = -6\) and \(y = -9\).[/tex]

There is sufficient evidence to support the claim. D. There is sufficient evidence to support the claim that more than 25% of the population believes that there is no solid evidence to support global warming.

Answers

Answer:

B. There is sufficient evidence to support the claim that less than 25% of the population believes that there is no solid evidence to support global warming.

Step-by-step explanation:

The following information has been availed;

n = 1501

sample proportion = 20% = 0.2

Level of significance = 0.01 = 1%

We are required to test the claim that less than 25% of the population believes that there is no solid evidence of global warming. In mathematical notation this claim can be written as;

p < 0.25, where p is the population proportion. From this information, we can formulate the following set of hypotheses;

H0: p ≥ 0.25

Ha: p < 0.25 (claim). This will be a left-tailed test.

The test statistic for hypothesis on population proportions is z, defined by the formula;

[tex]z=\frac{sampleproportion-p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]

where p is the population proportion under the null hypothesis, that is p = 0.25.

Using the given information , the test statistic becomes;

[tex]z=\frac{0.2-0.25}{\sqrt{\frac{0.25(1-0.25)}{1501} }}=-4.4736[/tex]

The next step is to compute the p-value in our left-tailed test;

p-value = P(Z < -4.4736) = 0

Our p-value is less than the level of significance and thus we reject the null hypothesis in favor of the alternative hypothesis which is also our claim. The final conclusion is thus;

There is sufficient evidence to support the claim that less than 25% of the population believes that there is no solid evidence to support global warming.

If cos x = sin(20 + x)° and 0° < x < 90°, the value of x is

We want to find the value of x, when

and 0°<x<90°

Recall that the sine and cosine are complementary trigonometric ratios.

Hence cos x = sin (90-x)

There are 19 numbers, that means that the 10th value will be the number in the middle

This means that the median is 23

4. An adult African elephant weighs
approximately 8 tons. Which comparis
is true?
8 tons = 20,000 pounds
6 8 tons < 20,000 pounds
8 tons < 100,000 ounces
08 tons = 24,000 pounds
5. A water bottle contains 2,000 milliliters


so what is the answer A,B,C,D​

Answers

Answer:

8 tons < 20,000

Step-by-step explanation:

1 ton = 2000 pounds

so 8 tons would be 16,000 which makes it less than 20,000

Final answer:

An adult African elephant that weighs approximately 8 tons is not equal to 20,000 pounds; instead, 8 tons equals 16,000 pounds. The provided comparison in the question is incorrect.

Explanation:

To determine if an adult African elephant that weighs approximately 8 tons is equal to 20,000 pounds, we need to convert tons to pounds using the unit equivalence 1 ton = 2,000 pounds. Multiplying 8 tons by the unit equivalence gives us:

8 × 2,000 = 16,000 pounds.

Knowing that the range of weight of a male African elephant is between 12,000 and 16,000 pounds, we can see that 8 tons does not equal 20,000 pounds. Therefore, the comparison 8 tons = 20,000 pounds is incorrect.

A correct comparison would be 8 tons = 16,000 pounds, which is not one of the options provided in the question.

As for the water bottle containing 2,000 milliliters, this is simply stating the volume capacity of the bottle but does not relate to the conversion between tons and pounds.

Solve using substitution or elimination.

y = x + 1
2x - 5y = 4

Answers

Substitute y = x + 1 into 2x - 5y = 4

-3x - 5 = 4

Solve for x in -3x - 5 = 4

x = -3

Substitute x = -3 into y = x + 1

y = -2

Therefore,

x = -3

y = -2

Find the solution set for this inequality: -3x -12> 8x+ 21

Answers

-3x - 12 > 8x + 21

Step 1: Combine like terms

x's go with x's (-3x and 8x). To do this add 3x to both sides

(-3x + 3x)  - 12 > (8x + 3x) + 21

-12 > 11x + 21

Normal numbers go with normal numbers (-12 and 21). To do this subtract 21 to both sides

(-12 - 21) > 11x + (21 - 21)

-33 > 11x

Step 2: Isolate x by dividing 11 to both sides

-33/11 > 11x / 11

-3 > x

Hope this helped!

Answer:

[tex]x\:<\:-3[/tex]

Step-by-step explanation:

The given inequality is:

[tex]-3x-12\:>\:8x+21[/tex]

We group similar terms to obtain:

[tex]-12-21\:>\:8x+3x[/tex]

Combine the similar terms to obtain:

[tex]-33\:>\:11x[/tex]

Divide both sides by 11;

[tex]-3\:>\:x[/tex]

Or

[tex]x\:<\:-3[/tex]
