Step-by-step explanation:

The given equation is in slope-intercept form:

y = mx + b

where the slope is m = -3 and the y-intercept is b = +2.

So, the graph will have a slope of ...

"rise"/"run" = -3 = -3/1

and will cross the y-axis at y=2.

Graphs A and B cross the y-axis in the right place, but only Graph B has a negative "rise" a x increases.

1. f(x)=x^2−4x, find f(−3)

2. f(x)=x^2−x, find f(−10)

3. f(x)=3x+1, find f(−3)

4. f(x)=4x−2, find f(8)

5. f(x)=x^2+2, find f(0)

Answers

f(x) is a function that takes some number x and outputs another one.

To get the output value, replace every instance of x in f(x) with the given number.

1. If f(x) = x ² - 4x, then

f (-3) = (-3)² - 4(-3) = 9 + 12 = 21

2. f(x) = x ² - x, so

f (-10) = (-10)² - (-10) = 100 + 10 = 110

3. f(x) = 3x + 1, so

f (-3) = 3(-3) + 1 = -9 + 1 = -8

4. f(x) = 4x - 2, so

f (8) = 4(8) - 2 = 32 - 2 = 30

5. f(x) = x ² + 2, so

f (0) = 0² + 2 = 0 + 2 = 2

9 Jean Junction is selling jeans at 25% off the regular price. Jeans regularly sell for $35. What is the cost of the jeans on sale?

Answers

Answer:

$26.25

Step-by-step explanation:

we can convert 25% directly to a decimal:

25% = 0.25

Then we find

25% of 35 = 0.25 x 35 = 8.75

35 - 8.75 = 26.25

So the jeans on sale cost $26.25

the sale price of the jeans will be $26.25

Here is a rectangle ABCD.
20 cm
30 cm
The length of the rectangle is increased by 20%.
The width of the rectangle is increased by 10%.
Find the percentage increase in the area of the rectangle.
12

Answers

Answer:

32%

Step-by-step explanation:

Area of rectangle ABCD = 20 * 30 = 600 Sq cm

After increasing the length and width of the rectangle by 20% and 10% respectively.

New length = 30 + 20% of 30 = 30 + 6 = 36 cm

New width = 20 + 10% of 20 = 20 + 2 = 22 cm

Area of new rectangle = 36*22 = 792 Sq cm

Increase in area = 792 - 600 = 192 Sq cm

Percentage increase in area

= (192/600) *100

= 32%

During the morning commute 60 cars and 12 trucks passed through the intersection. What is the ratio of cars to trucks?

Answers

Answer: 60:12, 60/12, or 60 to 12.

Step-by-step explanation:

To find the ratio, we must find 2 values. The values in this case is 60 and 12. 60 being cars and 12 being trucks.

So to write the ratio, we must put the cars first, then the trucks second.

So 60 first, and 12 second.

And remember, there are 3 ways to write ratios.

So we can write it like 60:12, 60/12, or 60 to 12.

The answers are 60:12, 60/12, or 60 to 12.

To most, he is known simply as Picasso. He was born on October 25th, 1881, and died on April 8, 1973. Pablos father was a drawing teacher, and he encouraged his sons artistic ability. When Pablo was ten years old, the family moved to Barcelona, Spain, where Pablo took an exam to enter a famous and prestigious art school, called La Llonga. The exam was supposed to take one month, but Pablo finished it in one day! He later moved to Paris, where was worked as an artist creating and exhibiting his drawings. During this time, he created his famous Blue Period works. They were called this because of their devotion to the color, and because they were quite somber in nature. In 1907, Picasso painted Les Demoiselles dAvignon, which is known to have been the first painting in the modern art movement. Artists from all over the world travelled to see this painting. Picasso created cubism, with a colleague named George Braque In the 1920s, Picasso continued his work by creating theatre sets. His work during this period was considered neo-classical, modern, surreal, and cubist. In 1937, there was a terrible bombing in a small Spanish town called Guernica. Picasso reacted by creating one of his most famous murals, a masterpiece named after the town of Guernica. Picasso then moved on to print making and lithography. He was never content to use a medium the way it was traditionally used, and came up with many inventive new ways to create art. He worked on etchings, engravings, and worked on many other techniques. Just before his 87th birthday, he completed a series called the 347 Series, in which he created three hundred and forty seven pieces of etching and engraving work between March and October! One of the most interesting things about Picasso is that he was the first artist to be famous during his own lifetime. He was quite a celebrity, and is considered one of the most important artists of the twentieth century.
