Answer:

The answer is B

Step-by-step explanation:

Move the constant to the left, 4x^2+2x-2-1=0

Calculate the difference, 4x^2+2x-3=0

then solve using quadratic equation (must too difficult to type out)

The Cheer Squad is raising money to pay for their trip to the State Finals. They already have $1200 and they are selling really

Vlad [161]

Answer:

10c + 1200 ≥ 3000, c≥ 180

Step-by-step explanation:

We know that they need at least $3000; meaning, it may be $3000 or more. This leaves us with eliminating the bottom two choices.

We then look at the first two choices. If we were to subtract from 1200, we would not know the total income amount that has been gained. It would also eventually give us negative numbers. We cannot have a negative amount earned. Instead, we would use the 10c+1200 because this would allow us to visualize that it needs to be greater than or equal to 3000

Point JJJ is located at (-4, 4)(−4,4)left parenthesis, minus, 4, comma, 4, right parenthesis. Select all of the following that a

In-s [12.5K]

Answer:

(-4, 8), (-4, 0), (0, 4) and (-4, 0)

Step-by-step explanation:

Given that point J is located at (-4, 4). The point4 units from point J can either be up, down, left or right. Hence:

The point 4 units up of point J = (-4, 4 + 4) = (-4, 8)

The point 4 units down of point J = (-4, 4 - 4) = (-4, 0)

The point 4 units right of point J = (-4 + 4, 4) = (0, 4)

The point 4 units left of point J = (-4, 4 - 4) = (-4, 0)

Therefore the points that are 4 units from point J are (-4, 8), (-4, 0), (0, 4) and (-4, 0).

That’s the number is written in standard scientific notation?

Nata [24]

Option D: 3.47*10^-7 is the correct answer

Step-by-step explanation:

In order to determine the number written in standard scientific notation, first of all we have to understand how the scientific numbers are written

the scientific numbers are written in the form of:

$a*10^n$

Here

a is a number between 1 and 10 while the value of n can be only integer (positive or negative)

so,

In the given options:

Option A has a number larger than 10 in place of a so it is not in standard notation

Option B has a number less than 1 in place of a so it is also not in standard notation

Option C has a number larger than 10 in place of a so it is not in standard notation

Option D is in standard scientific notation as 1<3.47<10 and the power of 10 is integer

Hence,

Option D: 3.47*10^-7 is the correct answer
