Answers

Answer:

(-3/4, -7/2)

Step-by-step explanation:

y= −2x − 5

y= 2x − 2

2y = -7

y = -7/2

y= 2x − 2

-7/2 = 2x - 2

2x = -3/2

x = -3/4

(x,y) = (-3/4, -7/2)

Answer:

-3/4 or -7/2

Scientists are examining two different strains of a particular bacteria. The length of one strain of the bacteria measures 0.000000143 mm, while the length of the second strain measures 0.0000000937 mm. How much larger is the first strain than the second?

Answers

Answer:

1.53 times

Step-by-step explanation:

We would have:

First strain : Second strain

0.000000143 mm : 0.0000000937 mm

How much larger is the first strain than the second?

We divide both by the length of the second strain

0.000000143/0.0000000937 : 0.0000000937 / 0.0000000937

1.52614727855 times

Approximately = 1.53 times

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as
whole numbers or as improper fractions in simplest form.

Answers

Given:

The equation is

[tex]-x+y=8[/tex]

To find:

The x- and y-intercepts.

Solution:

We have,

[tex]-x+y=8[/tex]

Put x=0 in the given equation to find the y-intercept.

[tex]-(0)+y=8[/tex]

[tex]y=8[/tex]

Put y=0 in the given equation to find the x-intercept.

[tex]-x+(0)=8[/tex]

[tex]-x=8[/tex]

[tex]x=-8[/tex]

Therefore, the x-intercept is -8 and the y-intercept is 8.

PLEASEEEE HELP ME IM TAKING A TEST
You are trying to find the area of a deck that is surrounding a rectangular pool. The length of the deck is 2x + 1 and the width is 5x + 2. The pool is a square with sides of 2x. Write the Polynomial that represents the area of ONLY the deck.

Answers

For deck,
Length = 2x + 1
Width = 5x + 2

For pool,
Length = 2x

Area of deck including pool = (2x + 1)(5x + 2) = 10x^2 + 4x + 5x + 2 = 10x^2 + 9x + 2

Area of pool = 2x * 2x = 4x^2

Area of only the deck = 10x^2 + 9x + 2 - 4x^2

= 6x^2 + 9x + 2

A number that can be written

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.

Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):

B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)

Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.

Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.

Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)

Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.

highest common factor is 5

therefore divide both numbers by 5

5/8

Figuring out ratios is pretty simple. Example: If the ratio of soccer balls to baseballs is 3:1 that means there are 3 soccer balls for every 1 baseball. Notice how it says “soccer balls to baseballs” and “3:1” the first type of ball/object is the subject for the 3 and the second ball/object is the number for the 1. So when it asks the ratio of chocolate cookies to the whole box, you need to put the number of chocolate cookies first (25) and the cookies in the whole box (40). So now the ratio is 25:40. Simplify and make it into fraction form and the answer is 5/8.

Answers

Answer: Correct answer is C -I just took the test

we have the function f(x) = 4(1/2)x, and we want to reflex it over the x-axis.

you can see in the graph that the reflex over this axis changes the sign of f(x) in all the points (where f(0) = 4, g(0) = -4, f(1) = 2, g(1) = -2, and so on), then the reflex, g(x) is equal to -f(x)

now we have:

g(x) = -f(x) = - 4(1/2)x

then the right answer is the third option:

g(x) = -4(1/2)x
