Y=6x-27
y=4x-17
Subtracting the two equations, we get;
0=2x-10
2x=10
x=5
Replacing for x in equation 2;
y=4(5)-17
y=20-17
y=3

Y=6x-27...........(1)
y=4x-17...........(2)

By comparison
6x-27=4x-17
=> 2x=10 => x=5
Substitute x=5 into (1)
y=6(5)-27=3
Check:
y=4(5)-17=3 as well.

What is the domain of the function y=in(x+2) x<-2 x>-2 x<2 x> x<-2 x>-2 x<2 x>2

aev [14]

For this case we must find the domain of the following function:

$y = ln (x + 2)$

By definition, the domain of a function is given by all the values for which the function is defined.

In this case, the argument of the expression must be greater than 0 to be defined.

$x + 2> 0\\x> -2$

Thus, the domain of the function is given by all the values of x greater than -2.

Answer:

Domain: $x> -2$

➷ 2) The integral of a constant follows this rule:

adx = ax

In this case, it is 1dx = 1x

This can be simplified to just x

Add a constant to this, to get the final answer of:

x + C

3) The integrals power rule is:

$x^adx = \frac{x^a^+^1}{a +1}$

Substitute the values in:

$\frac{x^5^+^1}{5 +1}$

This can be simplified to:

$\frac{x^{6} }{6}$

Add a constant to this to get the final answer of:

$\frac{x^{6} }{6} +C$

➶ Good Luck (:

CAN SOMEONE HELP .. WITH THE RIGHT ASWER PLZZ...

Ksenya-84 [330]

B. Add -12x to both sides. Then divide all terms by -2. The positive 12 on the right side will be a -6 and the -42 will be a positive 21. The inequality sign is always switched whenever the equation is divided by a negative number.

Please the question is on the picture

Artyom0805 [142]

The question in the picture is very different from the question before the picture.

Half of 12 is ____
is a different question than
12 is ____ halves

When you say, "Halves of 12, 10, ..." it looks like you're asking the first version.

One of something is 2 halves. That is, the number of halves is exactly two times the number of "somethings." Hopefully, you can multiply each of these numbers by 2.

12*2 = 24
10*2 = 10
13*2 = 26
15*2 = 30
8*2 = 16
5*2 = 10
