HELP WITH THIS MATH QUESTION
Bingel [31]

Answer:

3

Step-by-step explanation:

The solution to a system of equations is the intersection point of two or more lines on a graph.

In this case, we see that at (1, 3)

Remember that this question is asking for the y intercept, not the full coordinates or the x intercept.

We know that the full coordinates are (1, 3), or (x, y), and since we need y, we know the y cooridnates are 3, not 1, since this is x.

So the first answer, A, is correct.

Hope this helps!

enyata [817]

Answer:

The amount that this CD will be worth at maturity would be $935.90. The right answer is B.

Step-by-step explanation:

In order to calculate How much will this CD be worth at maturity we would have to use and calculate the formula of future value as follows:

Future Value=Present value×(1+i/n)∧nt

Future Value=$810×(1+2.9%/4)∧(4×5)

Future Value=$935.90

The amount that this CD will be worth at maturity would be $935.90

Simplify the variable expression by evaluating it's numerical part m-13+42-6
goldfiish [28.3K]

ANSWER

m + 23

EXPLANATION

The given expression is

m - 13 + 42 - 6

We regroup the numerical parts to get;

m + 42 - 6 - 13

Now let us simplify the negative numbers.

m + 42 - 19

We now subtract 19 from 42 to get;

m + 23

We can't simplify further

Hence the simplest form is:

m + 23

Sin x= 1.5<br> value of x
alina1380 [7]

Answer:

x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z

or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z

Step-by-step explanation:

Solve for x:

sin(x) = 1.5

1.5 = 3/2:

sin(x) = 3/2

Take the inverse sine of both sides:

Answer:  x = π - sin^(-1)(3/2) + 2 π n_1 for n_1 element Z

or x = 2 π n_2 + sin^(-1)(3/2) for n_2 element Z
