What is the slope of the line represented by the equation –5x+2y= 10–5x+2y= 10 ?A)–5/2

B)–2/5

C)2/5

D)5/2

Answers

Answer 1

Answer:

The slope of the line represented by the given equation is: A. $(5)/(2)$

Given the following equation:

$-5x+2y=10$ ....equation 1

To find t:

The standard form of an equation of line is given by the following formula;

$y = mx + b$ .....equation 2.

Where:

x and y are the points.

m is the slope.

b is the intercept.

From equation 1:

$-5x+2y=10\n\n2y = 5x + 10\n\ny = (5)/(2)x + 10$

Comparing eqn 1 and eqn 2:

Slope = $(5)/(2)$

Answer 2

Answer: Think you accidentally typed -5x + 2y = 10 twice.

Anyhow, let's rearrange the equation to match the equation for a line which is y = mx + b:

-5x + 2y = 10

2y = 5x + 10

y = 5/2x + 5

Now, the slope in a line is the m value. So 5/2 is the slope.

y = 5/2x + 5

Which expression is equivalent to(2x^5+7x^3)-(5x^2-4x^3)

Answers

Answer:

The equivalent expression is $2x^5+11x^3-5x^2$

Step-by-step explanation:

Given: $(2x^5+7x^3)-(5x^2-4x^3)$

Here we have expression and to simplify it

$\Rightarrow (2x^5+7x^3)-(5x^2-4x^3)$

Distribute minus sign

$\Rightarrow 2x^5+7x^3-5x^2+4x^3$

Combine the like terms (whose variable part same)

$\Rightarrow 2x^5+(7x^3+4x^3)-5x^2$

$\Rightarrow 2x^5+11x^3-5x^2$

Equivalent expression $\Rightarrow 2x^5+11x^3-5x^2$

Hence, The equivalent expression is $2x^5+11x^3-5x^2$

Which number is 164,502,423 decreased by 100,000?

Answers

Hello!

This is very basic math.. So I should be able to help you :)
The correct answer you should have gotten is: $164, 402, 423$

You should have subtracted from the hundred thousands place, which would have brought you down "1" hundred thousand points. . .

Hope it Helped :)

If you'd want the answer you have to do 164,502,423 subtract 100,000 which all you have to do is subtract from the hundred thousands place which is in this case 500,000 so it would be 164,402,423. I hope i gave a good understanding :)
