Answer: 32 cookies

Step-by-step explanation: Divide 24 by 3 to find 25% of the cookies you made. 24 divided by 3 is 8. Multiply 8 by 4, since 25% of your cookies times 4 would give you 100% of your cookies. 8 x 4 = 32 cookies.

Which equations are equivalent to log 4x=3
Lady bird [3.3K]
I'm not sure that this is what you wanted, but the solution is x = 2500
log(4x) = 3 \\ rule > \: log_{a}(b) = x < = > \: b = {a}^{x} \\ 4x = {10}^{3} \\ 4x = 10 \: 000 \\ x = \frac{10 \: 000}{4} \\ x = 2500
Note: when we have no number as the logarithmic base, it is 10 by default.

Use the quadratic expression 15x2+14x−16 to answer the questions.
marusya05 [52]

Answer:

A: second one or middle choice

B: (5x + 8)(3x - 2)

Step-by-step explanation:

First question (A)

It is a trinomial. You can't use the difference of squares on it. The difference of squares have two terms as an answer.

It is not a perfect square. 15 is not a perfect square and c would have to be positive not minus to even think about using a perfect square.

So the A answer is the second one. You need two different binomials to factor this.

Second Question

You could try all the possible pairings and solve them by brute force.

The are five choices the go with the first one (3x + 4). Eventually you would get the answer, you would have to try 5 + 4 + 3 + 2 + 1 = 15 attempts.

There must be a shorter way.

14 means that the expressions are fairly far apart. This was just luck on my part. There is no logic. 8 and 2 for 16 are fairly far apart.

(5x + 8)(3x - 2)

The middle term is 8*3x - 2*5x = 14x and that looks like the answer.

Write an algebraic equation to match each graph. (These graphs are not drawn to scale!) please help! i will make brainliest answ
ddd [48]

Answer:

the expression of this function is:

f(x)=|x-1|-1

Step-by-step explanation:

This graph corresponds to an absolute value function, which as you can see has the minimum (vertex) at the point (1, -1) on the plane, and also that goes through the origin of coordinates (0, 0)

therefore, notice that from the point (0, 0) to (1, -1) there is a slope of "-1" which is going to characterize the steepness of the x- variable that resides inside the absolute value function. since the vertex has also moved from the characteristic (0, 0) in the function:

f(x)=|x|

then we have to include a horizontal shift to the right in one unit (by subtracting 1 units from x), and a vertical shift  downwards one unit (by subtracting 1 from the full absolute value expression) in order to shift the vertex to the position (1, -1):

f(x)=|x-1|-1
