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

Answers

Answer 1

Answer:

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

Answer 2

Write the standard form of the line that contains a y-intercept of -3 and passes through the point (3,0). Include yourwork in your final answer. Type your answer in the box provide to submit your solution.

Answers

Answer:

y = -3x + 9 is your answer.

Step-by-step explanation:

So your y-intercept is the slope. Here is the equation we are going to use:

y - y_1 = m(x - x_1)

y_1 = 0

x_1 = 3

m = -3.

y - 0 = -3(x - 3)

y - 0 = -3x + 9

y = -3x + 9 is your answer.

Final answer:

The standard form of the line is y = x - 3.

Explanation:

To find the standard form of a line, we need two pieces of information: the slope of the line and a point on the line. Given that the line has a y-intercept of -3, we know that the y-coordinate is equal to -3 when the x-coordinate is 0. So, we have the point (0, -3). We also know that the line passes through the point (3, 0). Using these two points, we can calculate the slope of the line:

Slope (m) = (change in y) / (change in x) = (0 - (-3)) / (3 - 0) = 3/3 = 1.

Now that we have the slope and a point on the line, we can use the point-slope form of a line to write the equation:

y - y1 = m(x - x1), where (x1, y1) are the coordinates of a given point and m is the slope of the line.

Substituting the values of (x1, y1) = (3, 0) and m = 1 into the equation, we get:

y - 0 = 1(x - 3)

y = x - 3

Therefore, the standard form of the line that contains a y-intercept of -3 and passes through the point (3,0) is y = x - 3.
