Hey there!!

What is slope-intercept form ?

Ans :- y = mx + b

Where ' m ' is the slope and ' b ' is the y-intercept.

Equation given :- y = kx + 2

Now, we know k is m or the slope and 2 y-intercept.

y-intercept can be given as a coordinate.

Hence, y - intercept 2 can be written as ( 0 , 2 )

Now we have 2 coordinates, ( 0 , 2 ) and ( -7 , 12 )

How do we find slopes ?

Ans :- Slope = [tex]\frac{y2- y1 }{x2-x1}[/tex]

Plugging in the values :

Slope = [tex]\frac{12-2}{-7-0}[/tex]

Slope = [tex]\frac{-10}{7}[/tex]

Hence, the value of 'k' is [tex]\frac{-10}{7}[/tex]

Hope my answer helps!

Answer:

k = -10/7

Step-by-step explanation:

1. Plug in (x,y)

2. You would get -7k+2=12

3. If you solve for k, you would get:

-7k = 10

k= -10/7

Approximately 15 million more cars and trucks were flex-fuel in 2016 compared to 2004.

The number of flex-fuel cars and trucks in 2004 was approximately 5 million. In 2016, this number increased to about 20 million. To find out how many more cars and trucks were flex-fuel in 2016, we need to subtract the number of flex-fuel vehicles in 2004 from the number in 2016.

Number of flex-fuel vehicles in 2016: 20 million

Number of flex-fuel vehicles in 2004: 5 million

More flex-fuel vehicles in 2016 = Number of flex-fuel vehicles in 2016 - Number of flex-fuel vehicles in 2004
= 20 million - 5 million
= 15 million

Answer:

b

Step-by-step explanation:

B: Every plane contains at least three points that do not lie on the same line

To answer this question, we will have to state the 5 axioms of Euclidean geometry and they are;

1. A straight line could be drawn between any two points; This means that as long as there is no obstacle between the two points, then we can say that it is possible to draw a straight line between both points. However, if there is an obstacle between the two points, then it is not possible to draw a straight line.

2. Any straight line that is terminated could still be extended indefinitely; A line segment may be bound by an endpoint, but a straight line is not bounded by any endpoint and as a result, it can be extended indefinitely in both directions.

3. A circle could be drawn with any given center point and any given radius; If for example we use a line segment bounded by two end points. If we use one of these 2 endpoints to be the centre of a circle and make the radius of the circle to be equal to the length of the line segment earlier used as an example, it means if we draw a circle, it will have a diameter that is twice the length of that same line segment.

4. All right angles are definitely equal; A right angle always has a measurement of 90°. This means that regardless of its' orientation, it will still remain 90°.

5. For any given point that is not on a given line, there will be exactly one line passing through the point that would not meet that same given line; This implies that two lines will be parallel to each other if they intersect a third line with the interior angle between them being 180°.

Looking at the given options in the question, the only one that doesn't correspond to any of these 5 axioms I have stated would be option B.

NO, the difference between two positive rational numbers is not always positive.

A rational number is any number that can be expressed as a fraction of two different integers and these integers in their fractional form are not equal to zero.

Now, let assume the two positive numbers are 8 and 12. In rational positive

number, the numbers will be: [tex]\mathbf{\dfrac{8}{1}}[/tex]  and [tex]\mathbf{\dfrac{12}{1}}[/tex]

The difference between these two rational numbers will not be positive because 12 is a larger number than 8.

[tex]\mathbf{=\dfrac{8}{1}-\dfrac{12}{1}}[/tex]

= -4

Therefore, the difference between two positive rational numbers is not always positive.

It would be 13 because if you add 3,6,and 4you get 13. Also you should add those because they are the only numbers not in the mushroom circle of the Venn diagram.

Answer:

13

Step-by-step explanation:

To round the number 0.1875 to the nearest hundredth, you look at the thousandths place. As the digit (5) is 5 or more, we round up, giving us 0.19.

When rounding a decimal number to the nearest hundredth, you need to look at the digit in the thousandth place.

The number 0.1875 has a 5 in the thousandths place.

In rounding, if the digit immediately after the place we're rounding to is 5 or larger, we round up, otherwise we round down. Hence, 0.1875 rounded to the nearest hundredth becomes 0.19.

To clarify, 0.1875 is between 0.18 and 0.19, but is closer to 0.19 because of the 5 in the thousandths place prompting the round up.

Answer:  No, she will not make it tot he best fishing spot on the lake.

Step-by-step explanation:

Since we have given that

Distance between the starting point and the best fishing spot = 27 miles

Speed at which Ameena drives = 35 miles per hour

Time she takes to drive her boat is given  by

[tex]\frac{2}{3}\text{ of an hour}[/tex]

As we know that ,

[tex]Distance=Speed\times time\\\\Distance=35\times \frac{2}{3}\\\\Distance=\frac{70}{3}\\\\Distance=23.33\text{ miles}[/tex]

But we have given that the best fishing spot in the lake is 27  miles away from her starting point ,

[tex]\text{And with this speed in }\frac{2}{3}\text{ of an hour he reached only }23.33 \text{ miles. }[/tex]

So,

No, she will not make it tot he best fishing spot on the lake.

No, she will not

Find how far Ameena's boat will have traveled at two thirds of an hour.

(35 miles per hour) (2/3 of an hour)= 23.33 miles

Ameena's boat will have traveled just over 23 miles. She will not have reached the best fishing spot which will still be approximately another 4 miles away.

To find how far Ameena's boat has traveled you multiplied the speed by the time, but since time is now the unknown variable, divide the distance by the speed

27 miles divided by 35 miles per hour to get 0.77 hours

What is the conversion for hours to minutes?

0.77 = 46.2 minutes

Remark

There are a couple of ways to do this. The easiest is to take the number of degrees between 42 and - 54 and divide by 12.

the number of degrees is abs(42) + abs(-54) = 42 + 54 = 96

Now divide by 12

Hours = 96 / 12 = 8 hours. I think the answer is A.

Answer:

[tex]\frac{9}{16}[/tex] cups of raisins are in each serving

Step-by-step explanation:

Unit rate defined as the rates are expressed as a quantity as 1 such as 2 meter per seconds or 4 miles per hour.

As per the statement:

The bake star bakery uses 2 1/4 cups of raisins to make 4 servings of trail mix.

⇒Cup of raisins = [tex]2\frac{1}{4} = \frac{9}{4}[/tex] and number of serving  = 4

We have to find the cups of raisins are in each serving

Then by definition of unit rate we have;

[tex]\text{unit rate per serving} = \frac{\frac{9}{4} }{4} = \frac{9}{16}[/tex] cups of raisins

therefore, [tex]\frac{9}{16}[/tex] cups of raisins are in each serving

k=-4

7k+2=4K-10

+10   +10

7k+12=4K

-7k      -7k

12=-3k

Divide both sides by -3

K=-4

The solution is k = -4.

To solve the linear equation 7k+2=4k-10, we need to isolate the variable k on one side of the equation. Here are the steps to simplify the equation and find the value of k:

Subtract 4k from both sides to eliminate the variable from the right side of the equation: 7k - 4k + 2 = 4k - 4k - 10, which simplifies to 3k + 2 = -10.

Subtract 2 from both sides to eliminate the constant term from the left side of the equation: 3k + 2 - 2 = -10 - 2, which simplifies to 3k = -12.

Divide both sides by 3 to solve for k: 3k / 3 = -12 / 3, which simplifies to k = -4.

Now we need to check the solution by substituting k = -4 back into the original equation to verify that it holds true:

7(-4) + 2 = 4(-4) - 10

-28 + 2 = -16 - 10

-26 = -26

The left and right sides of the equation are equal, confirming that k = -4 is the correct solution. Thus, the steps are justified and the solution is reasonable

A container has 17 and 1/2 cups of lemonade.

Asher gives each of his classmates 5/6 of a cup.

He gives away all of the lemonade.

Solution:

There are 17.5 cups of lemonade.

Each classmate receives 5/6 of a cup.

So the number of classmates = Number of cups ÷  proportion of a cup each student receives

Number of classmates = 17.5 ÷ 5/6 = 21 classmates

There are 21 classmates.

Answer:

21 classmates.

Step-by-step explanation:

We have been given that a container has 17 1/2 cups of lemonade. Asher gives each of his classmates 5/6 of a cup.

To find the number of classmates that will get lemonade, we will divide total amount of lemonade by amount given to each classmate.

[tex]\text{Classmates that will get lemonade}=17\frac{1}{2}\div\frac{5}{6}[/tex]

Convert mixed fraction into improper fraction:

[tex]17\frac{1}{2}\Rightarrow=\frac{17\times 2+1}{2}=\frac{34+1}{2}=\frac{35}{2}[/tex]

[tex]\text{Classmates that will get lemonade}=\frac{35}{2}\div\frac{5}{6}[/tex]

Convert into multiplication problem by flipping the 2nd fraction:

[tex]\text{Classmates that will get lemonade}=\frac{35}{2}\times\frac{6}{5}[/tex]

[tex]\text{Classmates that will get lemonade}=\frac{7}{1}\times\frac{3}{1}[/tex]

[tex]\text{Classmates that will get lemonade}=7\times3[/tex]

[tex]\text{Classmates that will get lemonade}=21[/tex]

Therefore, Asher gave lemonade to 21 classmates.

There will be 28 unique speed dates in total.

In this speed dating event, there are 8 people who each have the chance to go on a speed date with every other person at the event. Since there are 8 people, there will be 8 - 1 = 7 speed dates for each person.

To find the total number of unique speed dates, we can use the formula n * (n - 1) / 2, where n is the number of people. Plugging in 8 for n, we get (8 * 7) / 2 = 28. So, there will be 28 unique speed dates in total.

A graph is used to show the relationship between related variables.

The complete table is:

[tex]\left[\begin{array}{cc}x&f(x)\\-1&1\\-3&1\\-5&3\\-6&3\end{array}\right][/tex]

A function is said to be even is:

[tex]f(x)=f(-x)[/tex]

This means that:

[tex]f(-1)=f(1)[/tex]

[tex]f(-3)=f(3)[/tex]

[tex]f(-5)=f(5)[/tex]

[tex]f(-6)=f(6)[/tex]

So, from the graph, we have:

[tex]f(1) = 1[/tex]

[tex]f(3) = 1[/tex]

[tex]f(5) = 3[/tex]

[tex]f(6) = 3[/tex]

This implies that:

[tex]f(-1) = 1[/tex]

[tex]f(-3) = 1[/tex]

[tex]f(-5) = 3[/tex]

[tex]f(-6) = 3[/tex]

Use the above values to complete the table. So, we have the complete table to be:
