Point C is the Image of C (-4,-2) under a Reflection across the x-axis.

Svetradugi [14.3K]

Step-by-step explanation:

$\text {Reflection Rule for across the X-axis: } (x,y) \rightarrow (x,-y)$

Using the point C (-4,-2) and the refection rule:

$(-4,-2) \rightarrow(-4, 2)$

$\text {C' should be (-4,2)}$

Arrange the following polynomial into descending order for x, then interpret the degree of the 3rd term. 2xy4 + 2x2y − 3y2 + 10x

malfutka [58]

To arrange the given polynomial in descending order of x, we only look at the exponent of x in each term and then write it in decreasing order of the value. We do as follows:

2xy^4 + 2x^2y − 3y^2 + 10x^3<span>
10x^3 + 2x^2 + 2xy^4 - 3y^2

The degree of the third term would be 5. The degree of a term is the sum of the exponents of the variables involved in the term.

Please solve and graph each inequality x-7<-12

Keith_Richards [23]

For this case we must resolve the following inequality:

$x-7$

Adding 7 to both sides of the inequality:

$x$

Different signs are subtracted and the major sign is placed.

$x$

Thus, the solution is given by all the values of "x" less than -5.

The solution set is: (-∞, - 5)

Answer:

$x$

Write the equation of a line that has a slope of -4 and goes through (-2,7).

Anni [7]

Answer:

$y = -4x - 1$

Step-by-step explanation:

Equation of a line is given as:

y = mx + b

Where

m is the slope

and

b is the y-intercept (y-axis cutting point)

Since we know slope is -4, we can write:

y= mx + b

y = -4x+ b

Given the point (-2,7) , we can say:

x = -2

and

y = 7

Plugging these 2 values, we can solve for b:

y = -4x + b

7 = -4(-2) + b

7 = 8 + b

b = 7 - 8

b = -1

Now, we have the equation:

$y = -4x - 1$
