Answer:

lg22/lg6

Step-by-step explanation:

6^u = 22

lg(6^u) = lg22

ulg6 = lg22

The vertex form of the equation of a parabola is y=3(x-40)^2-22. What is the standard form of the equation?

Leya [2.2K]

y=3(x-40)^2-22
y = 3(x^2 - 80x + 1600) - 22
y = 3x^2 - 240x + 4800 - 22
y = 3x^2 - 240x + 4778

answer
 standard form of the equation
y = 3x^2 - 240x + 4778

What is the equation of a line that contains the point (4, 0) and is parallel to x + y = 2?

gogolik [260]

Answer:

x + y = 4 or y = -x + 4

Step-by-step explanation:

0 = -1[4] + b

4 = b

y = -x + 4

If you want it in Standard Form:

y = -x + 4

+x +x

_________

x + y = 4 >> Line in Standard Form

* Since the rate of change [slope] is -1 and that parallel lines have SIMILAR SLOPES, -1 remains the same.

Fiona was playing a game in which she rolled two number cubes. Cube #1 had the integers 1, 2, 3, 4, 5 and 6 on its faces. Cube #

Gnom [1K]

When Fiona rolled Cube #2, she got a number -2 as she got 2 while rolling Cube #1 and the sum of the value on the cubes was 0.

As we know Cube #1 has integers 1, 2, 3, 4, 5, 6 on its faces and Cube #2 has -1, -2, -3, -4, -5, -6 on its faces.

It is also given that Fiona got 2 when she rolled cube #1 and the value of the sum on both the cubes is 0.

So it is clear that on Cube #2, the number must be -2 as in that case only, the sum of the values will be 0.

To prove

2 + (-1) = 1

2 + (-2) = 0

2 + (-3) = -1

Hence, the number she got on Cube #2 is -2.
