Answer:
1 11/21
Step-by-step explanation:
6/7 + 2/3 = 32/21
32/21 simplified is 1 11/21
Answer:
y = 2x-3
Step-by-step explanation:
The y intercept is -3. The slope is change in y/change in x. 2/1 = 2
You have to combine like terms (terms that have the same variable(x,y....) and power/exponent)²³
(4x³ - 4 + 7x) - (2x³ - x - 8) Distribute -1 into (2x³ - x - 8)
(4x³ - 4 + 7x) + (-)2x³ - (-)x - (-)8 (two negative signs cancel each other out and become positive)
(4x³ - 4 + 7x) - 2x³ + x + 8 Now combine like terms
4x³ - 2x³ + 7x + x - 4 + 8 (I rearranged for the like terms to be next to each other)
2x³ + 8x + 4 It is equivalent to B
Combine like terms
(I rearranged for the like terms to be next to each other)
It is equivalent to D
(x² - 2x)(2x + 3) Distribute x² into (2x + 3) and distribute -2x into (2x + 3)
(x²)2x + (x²)3 + (-2x)2x + (-2x)3
When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together
2x³ + 3x² - 4x² - 6x Combine like terms
2x³ - x² - 6x It is equivalent to A
[Info]
When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (You can combine the exponents only if they have the same variable)
For example:

(You can't combine them because they have different exponents of y and x)

To solve the inequality:

Add 1 to the sides of the inequality:

Then

Dividing all the inequality by 5, we have:

Graphically:
Or, in the interval notation(-1, 1/5).
Hello,
<span>The diagonals of a rhombus are perpendicular:
3x+x+40=90
==> 4x=50
==> x=12.5°
