Show that (√7+i√3/√7-i√3 + √7-i√3/√7+i√3) is real​

To have infinite solutions both equations need to be equal

Since they subtract 5 from the right side, subtract 5 from the left side.

X is multiplied by 1/2 on the left , so multiply x by 1/2 on the right side.

1/2x -5 = 1/2x-5

Answer: c.2*1

Step-by-step explanation: in the picture

You need to remember two definitions.

First, the dimensions of a matrix are the number of rows by the number of columns. If a matrix has a row and b columns, it's an a*b matrix.

Second, before computing the product of two given matrices, you need to check an important condition.

If a matrix A has i row and j columns. And a matrix B has k row and l columns we can not apply the product AB only if j = k. In other words the numbers of columns of A (j) must be equal to the number of rows of B (k).

If this condition is checked, than the new matrix will be of dimensions : ixl

In our case i = 2, j = 3, k = 3, l = 1

So the dimensions will be 2x1 so the answer is C.

Good luck

Answer:

D

Step-by-step explanation:

Answer:

8. 14x+6+16x+4=130

30x+10=130

30x+10-10=130-10

30x=120

x=4

10. 11x+3-85=5x-10

11x+3-85-5x=5x-10-5x

6x+3-85=-10

6x+3-3-85+85=-10-3+85

6x=72

Answer: 1.78 teaspoons

Step-by-step explanation:

The recipe says: 27 cookies/2 teaspoons Vanilla extract. Let's abbreviation this conversion factor as (27/2)C/V, where C is cookie and V is 1 teaspoon vanilla extract. We have both 13.5C/V and 1V/13.5C as conversion factors. 13.5 cookies is equivalent to 1 teaspoon vanilla, or 1 teaspoon vanilla is equivalent to 13.5 cookies. We can multiply ofr divide either of these factors, since they are both equivalent to 1, and you can mukltiply or divide anything by 1 without changing it's accuracy. The atual numbers will change, but the units will also change, making it a valid result.

We want 24 cookies. Use one of the conversion factors to find the teaspoons vanilla extract required:

1) We can divide by (27C/2V)

24C/((27C/2V) = 1.78 teaspoons

or

2) we can multiply by (1V/13.5C)

24C*(1V/13.5C) = 1.78 teaspoons

Answer:

Hey there, first let's find the slope.

M=y2-y1/x2-x1.

M=7-3/2-1 which is 4/1.

So your slope is 4

So now we have y=4x+b.

Now we need our Y-intercept (B). which is -1

So your answer is Y=4x-1

Answer:

y=2x-6

Step-by-step explanation:

The intercept is -6 so -6 and you take two points on the line e. g. (3,0) and (2,-2) You would do -2-0 to get -2 and 2-3 to get -1. -2 divided by -1 equals 2. The slope is two.

The expression of 5^20 as a power of 25 can be written as 25^10.

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

We need to express 5^20 as a power of 25

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" means this statement might change from text to text slightly.

Thus, 5^20 can be written as ;

(5^2)^10 = 25^10

Therefore, the expression of 5^20 as a power of 25 can be written as 25^10.

Step-by-step explanation:

f ( x ) = 3 x − 7

g ( x ) = 3 x + 9

f(g(2))

First find g(2)

g(2) = 3(2)+9 = 6+9 = 15

Then find f(15)

f(15) = 3*15 -7 = 45 -7 =38
