Answer:

First of all, we need to define each element.

A point can be defined as a location shown by specific coordinates (x, y).

A ray is a line that begins at a specific point, but is endless in the other extreme.

A right angle is define as an angle that measures 90 degrees.

Having said all that, we attached an image with 4 points, 2 rays and 1 right angle.

olasank [31]

Answer:

it is very easy so focus

Step-by-step explanation:

$\frac{a}{b} = \frac{4}{7}$

b is more than a by 90

$\frac{a}{a + 90} = \frac{4}{7}$

$7a = 4a + 360$

$3a = 360$

$a = 120$

Add the pair of mixed numbers below, make sure ur answer is fully reduced.<br><br> 7 1/5 + 3 2/5

zavuch27 [327]

Answer:

10 3/5

Step-by-step explanation:

Convert mixed fraction to improper fraction.

$7\frac{1}{5}=\frac{(7*5)+1}{5}=\frac{35+1}{5}=\frac{36}{5}\\\\3\frac{2}{5}=\frac{17}{5}\\$

Now add

$7\frac{1}{5}+3\frac{2}{5}=\frac{36}{5}+\frac{17}{5}\\\\=\frac{36+17}{5}\\\\=\frac{53}{5}\\\\= 10\frac{3}{5}$

Which of the following is true regarding the solution to the logarithmic equation below?

lidiya [134]

Answer:

Option C.

Step-by-step explanation:

Note: It is given question and option "=" sing is missing. On some places it should be "=" instead of "=".

Consider the given equation is

$\log_2(x+11)=4$

Using properties of \logarithm we get

$(x+11)=2^4$ $[\because \log_ax=b\Leftightarrow x=a^b]$

$x+11=16$

$x=16-11$

$x=5$

The solution is x=5.

To check the solution, substitute x=5 in the given equation.

$\log_2(5+11)=4$

$\log_2(16)=4$

$\log_22^4=4$

$4=4$

$LHS=RHS$

Therefore, x-5 is a true solution because $\log_2(16)=4$ .

What is the conjugate of x-square root of 2

Nana76 [90]

The conjugate of a binomial, is pretty much just the same thing, but with a different sign in between, so,

pelican + canary conjugate => pelican - canary

a + b conjugate => a - b

-a - b conjugate => -a + b

and so on, therefore

x - √2 conjugate => x + √2
