What is the degree of the monomial?<br> a. 6x2<br> b. −x3y3<br> c. 7x

sergiy2304 [10]

Answer:

a. 2

b. 6

c. 1

Step-by-step explanation:

The degree is the highest exponent on the variable in an expression

a. 2

b. 6

Both x and y have exponents of 3. To determine the degree, add the exponents together. 3+3=6

c. 1

When no exponent is present on the variable, it is always 1.

Which inequality is represented by the graph?

Taya2010 [7]

Answer:

Option B

Step-by-step explanation:

Notice that the region of the inequality is bounded by a line.

The first thing to do is find the equation of this line.

Note that the line intersects the x-axis at $x = 3.5$ and intercepts the y-axis at $y = -2.5$

We know that the equation of a line has the following form:

$y = mx + b$

Where m is the slope of the line and b is the intercept with the y axis.

So we already know that:

$b = -2.5 = -\frac{5}{2}$

Then we know that when $x = 3.5$ then $y = 0$

Thus:

$0 = 3.5m -2.5$

Ahroa we clear m.

$m = \frac{2.5}{3.5}\\\\m = \frac{5}{7}$

Then, the equation of the line is:

$y = \frac{5}{7}x -\frac{5}{2}$

We can also multiply by -2 both sides of the equation and we have:

$-2y = -\frac{10}{7}x +5$

Then:

$\frac{10}{7}x -2y =5$

The option that contains this equation is option B.

To verify it, enter a point within the shaded region, such as the point (0,0), in the selected inequality. If the inequality is satisfied then option B is correct

$\frac{10}{7}x -2y\leq5\\\\\frac{10}{7}(0) -2(0)\leq5\\\\0\leq5$

The inequality is satisfied because 0 is less than 5. Then the correct option is B

The line y = 5x/3 + b goes through the point (7, –1). What is the value of b?

mars1129 [50]

Answer:

$y=\frac{5}{3} x-\frac{38}{3}$

the value of b is -38/3

Step-by-step explanation:

$y=\frac{5}{3} x+b$ goes through the point (7,-1)

we need to find out b for the given equation using (7,-1)

Plug in 7 for x and -1 for y

$y=\frac{5}{3} x+b$

$-1=\frac{5}{3} (7)+b$

$-1=\frac{35}{3}+b$

subtract 35/3 from both sides

$-1 -\frac{35}{3} =b$

$\frac{-38}{3} =b$

Replace it in the original equation

$y=\frac{5}{3} x-\frac{38}{3}$

The volume of a cube is given by v=x^3 where x is the length of an edge find the rate at which the volume is changing with respe

IceJOKER [234]

The volume (when x = 10) would be 1,000 cubic units (10^3).
