Answer:

[tex]-1\frac{2}{3}[/tex]

Step-by-step explanation:

2/3 ÷ -2/5.

Flip -2/5 to -5/2 so that it can be multiplied.

2/3 × -5/2 = -10/6.

Reduce.

-10/6 reduced is -5/3.

Extract the whole number from this fraction to make it a mixed number.

-5/3 is equal to -1 2/3

Hope this helps!

We can do the inverse, where division basically becomes multiplication. You just flip the denominator and numerator (lower and upper part of the division sign).

[tex]\frac{2}{3} *-\frac{5}{2}[/tex]
The negative stays even when you inverse it. Make sure on future problems you inverse whats being divided, which in this case was -2/5.

We can now multiply across and get:
[tex]- \frac{10}{6}[/tex] as 2•5=10, 3•-2=-6. Therefore -10/6.

Which can be simplified into [tex]-1 \frac{2}{3}[/tex]. This is because 10 goes into 6 once leaving 4. That makes it -1 4/6, but 4/6 can be reduced by a common factor, 2. So just divide 4 and 6 by 2, which is 2/3. So thats why it is -1 2/3.

Answer:

(4,1), (4,2) pairs can be removed to make relation a function.

Step-by-step explanation:

Function states the relationship of ordered pairs where set A must have unique elements.

Point (2, 4) was reflected over the x axis to give (2, -4). It was then dilated by a scale factor of 2 to get (4, -8). Hence (2, 4) ⇒ (4, -8)

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.

Translation is the movement of a point either up, down, left or right on the coordinate plane.

Point (2, 4) was reflected over the x axis to give (2, -4). It was then dilated by a scale factor of 2 to get (4, -8). Hence (2, 4) ⇒ (4, -8)

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The slope of the lines is -1, and the equation of the parallel line is y-x-6.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The parallel line passes through the points (-4,-2) and (-3,-3). Therefore, the slope of the line is,

Slope = (-2 + 3) / (-4 + 3) = 1/-1 = -1

The equation of the parallel line that is passing through point P is,

y = mx + c

y = -x + c

-3 = -(-3) + c

-3 -3 = c

c = -6

Hence, the slope of the lines is -1, and the equation of the parallel line is y-x-6.

Step-by-step explanation:

When computing a consecutive sum of integers with a difference of 1.

Use gauss's formula of (n/2)(first number + last number).

with n being the # of integers.

Since it is ascending and descending, it can be broken down into 2 sequences:

1 + 2 + 3 + ... + 99 and 1 + 2 + 3 + ... + 100.

Once each is calculated, add them up to find the value.

So:

1 + 2 + 3 + ... + 99 = (99/2)(100) = 4950.

1 + 2 + 3 + ... + 100 = (100/2)(101) = 5050.

Answer:

Magnitude and Direction is 928 and 44

Step-by-step explanation:

For a Vector w = (x)i+(y)j

The Magnitude of w [tex]=\sqrt{x^{2} +y^{2} }[/tex]

and the Direction of w [tex]=tan^{-1}(\frac{y}{x} )[/tex]

So for our Question , w = - 168i - 160j

Then -4w = -4 (- 168i - 160j) = (-4*-168)i +(-4*-160)j = 672i + 640j

Then the Magnitude of -4w = [tex]\sqrt{672^{2} +640^{2} } =928[/tex]

and the Direction of -4w = [tex]tan^{-1}(\frac{640}{672} )=tan^{-1}(\frac{20}{21} )=44[/tex] ( to the nearest whole number)

Answer:

For plan B to save money cell phone user need to send 3000 texts per month as [tex]\frac{x}{y}[/tex] expresses the average texts sent per month by cell phone user and its obtained value is 3000.

Step-by-step explanation:

In the question it is given that a cell phone company offers two plans for minutes.

Plan A: $20 per month and $1 for every one hundred texts.

Plan B: $50 per month with free unlimited texts.

It is required to find that how many texts would be needed to send per month for plan B to save money. be needed to send per month for plan B to save money.

Step 1 of 5

In Plan A $20 per month and $1 for every one hundred texts are costed so the cost of Plan A is given by following equation,

[tex]$A=20 y+\frac{x}{100}$[/tex]

In Plan B $50 per month with free unlimited texts are costed so the cost of Plan B is given by following equation,

[tex]$$B=50 y$$[/tex]

Step 2 of 5

Now comparing the obtained equations [tex]$A=20 y+\frac{x}{100}$[/tex]

and B=50y.

[tex]$20 y+\frac{x}{100}=50 y$$[/tex]

Step 3 of 5

Subtract 20y from both the sides of the obtained equation [tex]$20 y+\frac{x}{100}=50 y$[/tex] and simplify using subtraction properties.

[tex]$$\begin{aligned}&20 y+\frac{x}{100}-20 y=50 y-20 y \\&\frac{x}{100}=30 y\end{aligned}$$[/tex]

Step 4 of 5

Multiply both the sides of the obtained equation [tex]$\frac{x}{100}=30 y$[/tex] by 100 and simplify using multiplication properties.

[tex]$$\begin{aligned}&\frac{x}{100} \cdot 100=30 y .100 \\&x=3000 y\end{aligned}$$[/tex]

Step 5 of 5

Divide both the sides of the obtained equation x=3000y by y and simplify using division properties.

[tex]$$\begin{aligned}&\frac{x}{y}=\frac{3000 y}{y} \\&\frac{x}{y}=3000\end{aligned}$$[/tex]

As [tex]$\frac{x}{y}$[/tex] expresses the average texts sent per month by cell phone user. So, for plan B to save money cell phone user need to send 3000 texts per month.

The distance between two points can be calculated by the formula given below

Distance between two points (x1,y1), (x2,y2)= d= √(x2-x1)²+(y2-y1)²

where (x1,y1) and (y1,y2) are the coordinates of the points.

The distance between the points which is of coordinates (3, -1) and (5, 4)

d= √(5-3)²+(4-(-1))²= √4+25= √29= 5.39 units

The distance between the points which is of coordinates (2, 3) and (4, 5)

d= √(4-2)²+(5-3)²= √4+4= √8= 2.83 units

The distance between the points which is of coordinates (-5, 7) and (8, 5)

d= √(8-(-5))²+(5-7)²= √169+4= √173= 13.15 units

The distance between the points which is of coordinates (-2, 4) and (3, -1)

d= √(3-(-2))²+(-1-4)²= √25+25= √50= 7.07 units

Therefore the distance between (3, -1) and (5, 4) is 5.39 units, the distance between (2, 3) and (4, 5) is 2.83 units, the distance between (-5, 7) and (8, 5) is 13.15 units and the distance between (-2, 4) and (3, -1) is 7.07 units.

Answer:

16.2 kilograms

Step-by-step explanation:

30 300-gram cans = 9000 grams of soup

18 400-gram cans = 7200 grams of vegetables

9000 + 7200 = 16200 grams

1000 grams = 1 kilogram

16200 / 1000 = 16.2 kilograms

The total amount of food students collect in kilograms will be equal to 16.2 kilograms food.

What is algebra ?

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.

The number of cans of soup in one box = 30 cans

And each can has 300 grams of soup.

So , the total amount of soup in one box is :

= 30 × 300

= 9000 grams of soup

Now , in the other box there are 18 cans of vegetables and each can has 400 grams of vegetable.

So , the total amount of vegetable in the other box is :

= 18 × 400

= 7200 grams

Total food students collect is :

= 9000 grams soup + 7200 grams vegetables

= 16200 grams food

We know that :

1000 grams = 1 kilogram

So , converting grams into kilograms we get :

16200 / 1000 = 16.2 kilograms food

Therefore , the total amount of food students collect in kilograms will be equal to 16.2 kilograms food.

Answer:

The second graph

Step-by-step explanation:

Well you're given the equation in slope-intercept form, which looks like: y=mx+b, where m is the slope, and b is the y-intercept. This is because the y-intercept is when x=0, so mx will becomes 0, thus leaving b alone, and making it the y-intercept. m is the slope because as x increases by 1, the y-value goes up by m, so the "rise" is m and the "run" is 1. The definition of the slope is rise/run so the slope would be m/1 or just m.

So let's analyze the equation: y=25x+40. the slope will be 25, and the y-intercept will be 40 (this is important for easily filtering very obviously wrong answer). So the linear equation will intersect the y-axis at (0, 40). Only one of the graphs intersects the y-axis at (0, 40) which is the second graph.
