Image is missing, so i have attached it.

Answer:

Rate of change = 2

Step-by-step explanation:

From the image attached, we are given a parabola which opens upwards with many points marked on the curve.

We are asked to find the rate of change for the interval between 3 and 6 on the x axis.

Now, rate of change of any function f(x) from a to b is given by the formula ;

Rate of change = [f(b) - f(a)]/(b - a)

For this question, a = 3 and b = 6

f(3) is simply the y-value when x is 3. On the graph, f(3) = -2

Similarly,f(6) = 4

Thus;

Rate of change = [4 - (-2)]/(6 - 3)

Rate of change = 6/3

Rate of change = 2

Hi!

This is definitely a trapezoid, as it has two equal sides and two inequal sides. It's not a parallelogram, because two sides eventually intersect. It is a quadrilateral, because it has four sides.

None of the others apply here.

Thomas has been offered two jobs. The first job pays $880.00 per week. The second job pays $790.00 per week plus 12% commission
LUCKY_DIMON [66]

Answer:

he has to make a sale of $750

Step-by-step explanation:

first job pays $880 per week

second job pays $790 per week

amount first job is paying more=$(880-790)

=$90

therefore,12% should $90 if he wants to make an equal amount as the first job is paying therefore,sale he has to do

12% of x=$90

12/100*x=$90

x=90*100/12

x=9000/12

x=$750

thus he has to make a sale of $750 to earn a 12% comission of $90

PLEASE HELP!! What is the value of x?
Black_prince [1.1K]
To find x, first we'll split the triangle in two right triangles.

The first triangle will be the one with sides (8,x+4,y) and the second triangle will be the one with sides (12,2x+1,y).

As you can see, these two triangles share the side 'y'.

To solve we'll do the following; first solve for 'y' by applying the Pythagorean theorem in the second triangle, and finally solve for 'x' applying Pythagorean theorem in the first triangle.

From the second triangle (12,2x+1,y) we solve for 'y' by writing:
y^{2}=12^{2}- (2x+1)^{2}=144-4 x^{2} -4x-1=

Now that we know 'y^2' we apply Pythagorean Theorem in the first triangle (8,x+4,y)
8^{2}= (x+4)^{2}+ y^{2}= (x^{2}+8x+16)+(143-4 x^{2} -4x)
64=159-3 x^{2} +4x

Now you solve the quadratic equation, you'll get a positive and negative value; as this are lengths, you take the positive and get:

x= \frac{19}{3}

(-6,-2) (-2,6) (6,2) (-2,-6)
LuckyWell [14K]

Answer:

(-6,-2)

Step-by-step explanation:

the solution is -6,-2 because y comes before x, and the line crosses in the negative axis.

I think that was what you were asking. I hope.
