How many solutions does the system have?

Answer:

f(-2) = 2

Step-by-step explanation:

The question is asking for the y-value of the point located at x = -2 on the graph. The point is at (-2, 2), so f(-2) = 2.

You need to work out the current UK percentage first.

Answer:

The table represents a proportional relationship

Step-by-step explanation:

Given

x ------ y

1 ------- 15

2 --------30

4 ---------60

5 -------- 75

Required

Determine if the table shows a proportional relationship

To check this, we make use of the following formula;

[tex]k = \frac{y}{x}[/tex]

Where k is the proportionality constant

When x = 1, y = 15

[tex]k = \frac{15}{1} = 15[/tex]

When x = 2, y = 30

[tex]k = \frac{30}{2} = 15[/tex]

When x = 4, y = 60

[tex]k = \frac{60}{4} = 15[/tex]

When x = 5, y = 75

[tex]k = \frac{75}{5} = 15[/tex]

Since the value of k for all values of x and y is the same; i.e. 15

Then, the table represents a proportional relationship

Linnea's company's revenue in 2017 is 36/25 of its revenue in 2016. What is Linnea's company's revenue in 2017 as a percent of its revenue in 2016?

Solution

Let

36x= Linnea's company revenue in 2017

25x=Linnea's company revenue in 2016

Percent of Linnea's company's revenue in 2017 as a percent of its revenue in 2016= 36x / 25x × 100

36x / 25x * 100

=1.44 × 100

Answer:

30,370 feet

Step-by-step explanation:

The difference in elevations between two points will be 30370 feet.

It is given that Mt. Everest is 29000 feet above sea level and the shore of dead sea is 1370 feet below the sea level.

We have to find out the difference in elevation between the two points.

What is algebra ?

Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.

As per the question ;

Height of Mt. Everest from sea level = 29000 ft. above

Height of shore of dead sea from sea level = 1370 feet below

As these both are in opposite directions , i.e., one above sea level and other below sea level , we should add both of these to find the difference in elevations between these two points.

i.e.,

The difference in elevations between two points will be ;

= 29000 + 1370

= 30370 feet

Thus , the difference in elevations between two points will be 30370 feet.

Answer:

-0.5 or -1/2

Step-by-step explanation:

The equation for slope is y₂-y₁ / x₂-x₁.

It should work with all of the points given. Any of the 2 points you choose will give you the slope -0.5 or -1/2.

The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

The average slope of a straight line ;

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

So slope  associated with two points (-2,1) , (0,0)

⇒ (0 - 1) / (0 + 2)

⇒ -1/2

Since all three points are in a straight line so slope must be the same.

Hence "The slope the straight line going through (-2,1) , (0,0) and (2,-1) is -1/2".

Answer:

HCF of 96 and 404 by prime factorisation method:-

Since, 96 = 2 × 2 × 2 × 2 × 2 × 3

and, 404 = 2 × 2 × 101

So, HCF of 96 and 404 = Product of common prime factors

                                 = 2 × 2 = 4

LCM = 2 × 2 × 2 × 2 × 2 × 101 × 3

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Given:

3 batches of brownies from 3/2 cups of chocolate left.

Step-by-step explanation:

From the question, we know that:

1/2 cups of chocolate = 1 batch of brownies

3/2 cups of chocolate = x

Cross Multiply

1/2 × x = 3/2

x = 3/2/1/2

x = 3/2 × 2/1

x = 3 batches.

That means she can make 3 more

3+1=4

Therefore, the batches of brownies can Luisa make is 4 batches.

Greetings from Brasil...

See the attached chart. The midpoint, M, has 8 units down on the Y axis. So the other half will also have 8 units after that point M. This is also true for the X axis.

Just make the difference between points T and M. For M and S they are the same quantities.

(0; 3) and (1; -5)

X: 1 - 0 = 1   (one unit until mid point)

Y: - 5 - 3 = - 8  (8 units until mid point)

To S:

S(W; Z)       M = center point coordinate value

W = M +  1 ⇒ W = 1 + 1 = 2

Z = M - 8 ⇒ Z = - 5 - 8 = - 13

Answer:

16.12 units

Step-by-step explanation:

distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

d = √[(8 - 10)² + (7 + 9)²]

d = √[(-2)² + (16)²]

d = √[4 + 256]

d = √260

d = 16.12

Answer:
