Given the function f(x) = 2x − 5 and g(x), which function has a greater slope?


x g(x)
2 0

6 10

1. f(x) has a greater slope.
2. g(x) has a greater slope.
3. The slopes of f(x) and g(x) are the same.
4. The slope of g(x) is undefined.

Answers

It’s 2 sorry if I’m wrong

Answer:  The correct option is

(B)  g(x) has a greater slope.

Step-by-step explanation:  We are given the following two functions :

[tex]f(x)=2x-5~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

and

x                    2                      4                    6

g(x)                0                      5                     10

Comparing equation (i) of f(x) with the slope-intercept form y = mx+c, we get

[tex]\textup{slope, m}=2.[/tex]

Now, we know that if a linear function contains two points (a, b) and (c, d), then its slope is given by

[tex]m=\dfrac{d-b}{c-a}.[/tex]

Since (2, 0) and (4, 5) are two points on g(x), so its slope will be

[tex]m=\dfrac{5-0}{4-2}=\dfrac{5}{2}=2.5.[/tex]

Therefore, slope of f(x) = 2 and slope of g(x) = 2.5.

Thus, slope of g(x) is greater.

Option (B) is CORRECT.

Final answer:

The sequence is not arithmetic; the terms are increasing by multiplying the previous term by 3.

Explanation:

This sequence does not follow an arithmetic pattern. In an arithmetic sequence, each term is found by adding a constant difference to the previous term. However, in this sequence, the terms are increasing by multiplying the previous term by 3. For example:

Term 1: 4

Term 2: 4 x 3 = 12

Term 3: 12 x 3 = 36

Term 4: 36 x 3 = 108

Since the terms are not increasing by a constant difference, this sequence is not arithmetic.

In the standard (4) coordinate plane, the coordinates of the midpoint of AB are (6,8) and the coordinates of A are
(3,2). What are the coordinates of B ?

A. (0,-4)
B.(3,6)
C.(9/2,5)
D. (9,14)
E.(-3,-6)

Answers

Final answer:

To find the coordinates of point B, use the midpoint formula and solve the equations.

Explanation:

To find the coordinates of point B, we can use the formula for finding the midpoint of a line segment. The midpoint of AB is given as (6,8), and the coordinates of A are (3,2). Let's call the coordinates of B as (x,y).

According to the midpoint formula, the x-coordinate of the midpoint is the average of the x-coordinates of A and B, and the y-coordinate of the midpoint is the average of the y-coordinates of A and B.

So, we can set up the following equations:

(3+x)/2 = 6 and (2+y)/2 = 8

Solving these equations, we find that x = 9 and y = 14.

Therefore, the coordinates of point B are (9,14).

10 yellow eggs out of 12 colored eggs ratios

Answers

10:12 is the ratio of 10 yellow eggs out of 12 colored eggs

Final answer:

The question asks for the ratio of yellow eggs to colored eggs, which is 10 yellow eggs to 12 colored eggs. Simplifying the ratio, we get 5:6. This concept of ratios is also seen in Mendel's genetic experiments with plants, where traits are passed in specific ratios like 3:1.

Explanation:

In mathematical terms, a student's question regarding the ratio of yellow eggs to the total number of colored eggs can be answered using simple division to derive a fraction or ratio. Given that there are 10 yellow eggs out of 12 colored eggs, the ratio can be expressed as 10:12.

However, ratios should be simplified to their smallest form to be more understandable; therefore, this ratio simplifies to 5:6 since both numbers can be divided by 2.

When looking at historical experiments, such as the ones conducted by Mendel, we find that phenotypic ratios play a significant role in understanding genetics. Mendel observed that traits could manifest in a specific ratio, like a 3:1 ratio for dominant to recessive traits. The ratios observed in the experiments provided can serve as examples to understand how ratios represent the occurrence of certain outcomes over others.

In this case, the ratio of yellow to green seeds in Mendel's experiment can serve as an analogy to understand the ratio of yellow eggs: both ratios quantitatively describe the presence of a certain characteristic compared to another.

Danielle needs to walk 3 miles. If she wants to reach her destination in 45
minutes (3/4hour), how fast does she need to walk?

Answers

Answer: She needs to walk 5 miles an hour

There's two numbers 2.5 miles and 0.5 hours, you divide that, and you get the number 5, so that means, 5 miles an hour

She needs to walk at a speed of 4 miles/hour to reach the destination in 45 minutes.

What is Speed?

Speed is the ratio of the total distance covered by an object and the required time to cover that by that object. It is also called Velocity.

[tex]Velocity=\frac{Distance}{Time}[/tex]

Velocity is the measurement which shows an object is how fast.

In this given problem,

The total distance Danielle needs to cover by walking is 3 miles.

She needs to reach the destination in 45 minutes

We know that,

60 minutes = 1 hour

1 minute = [tex]\frac{1}{60}[/tex] hour

45 minutes [tex]=\frac{45}{60}=\frac{3}{4}[/tex] hours

So she has to have the velocity/speed of [tex]=\frac{3}{\frac{3}{4}}=3\times\frac{4}{3}=4[/tex] miles/hour

Hence she needs to walk 4 miles/hour.

Find the vertex of this parabola:
y = -5x2 - 10x - 15
Enter the correct answer.

Answers

Answer:

Vertex of parabola (-1, -10)

Step-by-step explanation:

For a given quadratic y = ax² + bx + c, the vertex (h, k) is found by computing h = –b/2a, and then evaluating y at h to find k. If you've already learned the Quadratic Formula, you may find it easy to memorize the formula for k, since it is related to both the formula for h and the discriminant in the Quadratic Formula: k = (4ac – b2) / 4a.

2

Answers

Answer:

1

Step-by-step explanation:

The last part of the line starts from (1,3) and goes to (4,0)

We have two points, so we figure out the equation of this line with the formula:

y = mx + b, where m is the slope and b is the y intercept

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{0-3}{4-1}=\frac{-3}{3}=-1[/tex]

So we can now write  y = -x + b

Plugging in a point (1,3), we get:

3 = -1 + b

b = 3+1 = 4

The equation is y = -x + 4

To find h(3), we substitute 3 into x and find the value of y:

y = -x + 4

y = -3 + 4

y = 1

Thus, h(3) = 1

b.
It turns out that they raised more than $500. Knowing this, what is the least
amount of money they could have raised?​

Answers

Answer:

A. $301

B. $721

Step-by-step explanation:

Let $x be the amount of money they raised.

Rowena tried to put the $1 bills into two equal piles and found one left over at the end, then

[tex]x=2q_1+1[/tex]

Polly tried to put the $1 bills into three equal piles and found one left over at the end, then

[tex]x=3q_2+1[/tex]

Frustrated, they tried 4, 5, and 6 equal piles and each time had $1 left over, then

[tex]x=4q_3+1\\ \\x=5q_4+1\\ \\x=6q_5+1[/tex]

Finally Rowena put all the bills evenly into 7 equal piles, and none were left over, then

[tex]x=7q_6[/tex]

This means [tex]x-1[/tex] is divisible by 2, 3, 4, 5 and 6 without remainder, so

[tex]x-1=2\cdot 3\cdot 2\cdot 5n=60n[/tex]

Hence,

[tex]x=60n+1, \ n\in N[/tex]

The smallest amount of money they could have raised is $301, because

[tex]x=60\cdot 5+1=301[/tex] is divisible by 7.

Now, the number [tex]x=60n+1[/tex] should be divisible by 7 and must be greater than 500.

So,

[tex]60n+1>500\\ \\60n>499\\ \\n>8[/tex]

When n = 9,

[tex]x=60\cdot 9+1=541[/tex] is not divisible by 7.

When n = 10,

[tex]x=60\cdot 10+1=601[/tex] is not divisible by 7.

When n = 11,

[tex]x=60\cdot 11+1=661[/tex] is not divisible by 7.

When n = 12,

[tex]x=60\cdot 12+1=721[/tex] is divisible by 7.

B. The least amount of money they could have raised is $721

Which shape has larger area: a rectangle that is 7 inches by 3/4 inch, or a square with a side length of 2 1/2 inches. Tell your reasoning.

Answers

Area= length multiplied by width

Area of rectangle:
Area=7 x .75
Area= 5.25

Area of square:
Area= 2.5 x 2.5
Area=6.25

The square has a larger area because when you multiply the length and width of both shapes the square has a larger sum

The square with a side length of  [tex]2\frac{1}{2}[/tex] inches has a larger area of 6.25 square inches, compared to the area of the rectangle which is 5.25 square inches.

To determine which shape has a larger area, let's calculate the area of both the rectangle and the square. The rectangle measures 7 inches by 3/4 inch, so its area is calculated by multiplying these dimensions:

Area of the rectangle = length ×width = 7 inches × [tex]\frac{3}{4}[/tex] inch = [tex]\frac{21}{4}[/tex] square inches or 5.25 square inches.

The square has a side length of [tex]2\frac{1}{2}[/tex] inches, which is equivalent to 2.5 inches. Hence, the area of the square is:

Area of the square = side ×side = 2.5 inches × 2.5 inches = 6.25 square inches.

Comparing the two, we can see that the square with a side length of [tex]2\frac{1}{2}[/tex] inches has a larger area of 6.25 square inches compared to the rectangle's area of 5.25 square inches.
