The standard for of this equation is x – y = 0

Firstly, options A and D are not in standard form, so they are not options.

To decided between B and C, we choose a point on the line and see if it works. For example, we'll use (2, 2).

x – y = 0

2 - 2 = 0

0 = 0

This is true for option C. Therefore, it is correct.

0.175 as a percentage

Paul [167]

Answer: 17.5%

To convert from decimal to percent, just multiply the decimal value by 100. In this example we have: 0.175 × 100 = 17.5% (answer).

➥ The ease way:

1) Move the decimal point two places to the right: 0.175 → 1.75 → 17.5.

2) Add a % sign: 17.5%

Answer: 17.5%

URGENT ANSWER NOW In △ABC, A=59∘, a=20, and c=21. What are the two possible values for angle C to the nearest tenth of a degree?

PilotLPTM [1.2K]

Answer:

The two possible values of C are 64.2° and 115.8°

Step-by-step explanation:

* In ΔABC

- a, b, c are the lengths of its 3 sides, where

# a is opposite to angle A

# b is opposite to angle B

# c is opposite to angle C

- m∠A = 59°

- a = 20

- c = 21

* To find the distance m∠C we can use the sin Rule

- In any triangle the ratio between the length of each side

to the measure of each opposite angle are equal

- c/sinC = a/sinA = b/sinB

* Lets use it to find the m∠C

∵ 21/sinC = 20/sin(59)

∴ sin(C) = 21 × sin(59) ÷ 20 = 0.9000256657

∴ m∠C = sin^-1(0.9000256657) = 64.16144°

∴ m∠C = 64.2°

∵ The value of sin(C) is positive

∴ Angle C may be in the first quadrant (acute angle)

or in the second quadrant (obtuse angle)

∴ The other measure of ∠C = 180 - 64.2 = 115.8

* The two possible values of C are 64.2° and 115.8°

a cell phone company is giving a 20℅ discount on all phone accessories which expression can used to find the sale price of an it

Sholpan [36]

Answer:

The expression that can be used is 0.80x

Step-by-step explanation:

Let

x ----> original price of an item

Remember that

$100\%-20\%=80\%$

That means---> the sale price is 80% of the original price

To find out the sale price, determine the 80% of the original price

$80\%=80/100=0.80$ ----> percentage in decimal form

Multiply the original price by the percentage in decimal form to obtain the sale price

$0.80x$

How can you classify the results of operations on real numbers

Jet001 [13]

There are different levels of classification when it comes to numbers. The general classification is between real numbers and imaginary numbers. Imaginary numbers are those with 'i' in them which is equal to √-1. Next, real numbers can be classified as rational or irrational. Irrational numbers are those that can't be expressed into fractions. Lastly, rational numbers are classified into integers and fractions.
