Answer:

x=3/radical2,-3/radical2,3/4

Step-by-step explanation:

By factoring you get

4x(2x^2-9)-3(2x^2-9)=(2x^2-9)(4x-3)=0

x^2=9/2, x=3/4

x=3radical2/2, -3radical2/2 , 3/4

Answer:

A = 110 degrees.

Step-by-step explanation:

< A and < B are same side angles so their values add up to 180 degrees, so:

5x + 20 + 9x - 92 = 180

14x - 72 = 180

14x = 252

x = 18.

So m A = 5(18) + 20

= 110 DEGREES.

A spanish class has a total of 33 students. The number of males is 17 more than the number of females. How many males and how ma

andrezito [222]

Answer:

25 males and 8 females.

Step-by-step explanation:

If x is the number of males and y = number of females we have the system:

x + y = 33

x - y = 17 Adding:

2x = 50

x = 25

so y = 33 - 25 = 8.

Is this equation linear or nonlinear and why? Thanks

mylen [45]

This equation is not liner because the equation is not a straight line. At the point (0, 23) the equation bends.

Start with Chanel’s sequence. How does a 90-degree counterclockwise rotation about the origin change the coordinates of a shape?

zmey [24]

When a shape is rotated, it must be rotated through a point.

90 degrees counterclockwise rotation negates the y-coordinates, and then swap the x and y-coordinates
Chanel is incorrect

The rule of 90 degrees counterclockwise is:

$(x,y) \to (-y,x)$

This means that:

The y-coordinate is negated
Then the y and x coordinates are swapped

However, Charlies transformation is incorrect.

This is so because, the shape was not rotated, but instead it was reflected across the x-axis.
Then, the shape was dilated

Using points L and Q

$L=(1,1)$

When L is reflected across the x-axis.

The rule is:

$(x, y) \to (x, -y)$

So, we have:

$(1, 1) \to (1, -1)$

Next, it is dilated by 2.

The rule of this is:

$(x,y) \to k(x,y)$

So, we have:

$(1,1) \to2 \times (1,-1)$

$(1,1) \to (2,-2)$

From the diagram, the coordinate of Q is:

$Q = (2,-2)$

Same as the calculated point

Hence, Chanel is incorrect
