Which point is an x-intercept of the quadratic function f(x) = (x – 4)(x + 2)?

2 answers:

7 1

We can find the x-intercept of the quadratic function when : f ( x ) = 0
( x - 4 ) ( x + 2 ) = 0
Therefore:
x - 4 = 0 or x + 2 = 0
Solutions: x 1 = 4, x 2 = - 2
Answer: D ) ( 4 , - 2 )

The radius of the large sphere is double the radius of the small sphere.

Vlad [161]

Answer:

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Remember that all the spheres are similar

Let

z ----> the scale factor

V_1 ---> the volume of the large sphere

V_2 ---> the volume of the small sphere

$z^3=\frac{V_1}{V_2}$

<em>Find the scale factor</em>

we know that

The radius of the large sphere is double the radius of the small sphere

The scale factor is 2

$z=2$

substitute the value oz z

$z^3=\frac{V_1}{V_2}$

$2^3=\frac{V_1}{V_2}$

$8=\frac{V_1}{V_2}$

$V_1=8V_2$

The volume of the large sphere is 8 times the volume of the small sphere

Answer:

(4z-5a)(2xy)

Step-by-step explanation:

8xyz-10axy

Check for similar terms/like terms

x and y are the same.

The hcf or highest common factor is 2.

The z and a are not common in both terms.

Factor.

Which of the following theorems verifies that WVU = RST?

Paladinen [302]

Answer: C. LA

Explanation:

Angle W = Angle R (given)
VU = ST (given)
Angle U = Angle T = 90 (right angle of the right triangle)

Then we can say that triangle VWU = SRT (ASA)

morpeh [17]

Answer:

5x + 6 = 3x + 7

-5x -5x

6 = -2x + 7

-7 -7

-1 = -2x

divide both sides by -2
