Which numbers are 9 units from −5 on this number line?
ExtremeBDS [4]

Using the number line, the numbers that are 9 units from -5 are: -14 and 4.

<h3>How to Locate a Number on a Number line?</h3>

To find two numbers that cover the same units from a given point on a number line, we can simply do the following:

  • Count the number of units given backwards/to the left from the point stated to get the first number.
  • Count the number of units given forwards/to the right from the point stated to get the second number.

Thus, we are asked to find the numbers that would be 9 units from -5, using the number line.

Count 9 units backwards/to the left from -5 to get the first number, which is: -14

Count 9 units forwards/to the right from the -5 to get the second number, which is: 4.

Therefore, the numbers that are 9 units from -5 on the number line, are: -14 and 4.

If x / 2y = 0.4 , A / 5B = 0.25 Then A + y / 5 =….... ​
shusha [124]

Answer:

\frac{x}{2y}  =  \frac{4}{10}  \\ 8y = 10x \\ y =  \frac{10x}{8} -  -  -  -  - 1  \\  \\  \frac{a}{5b}  =  \frac{25}{100}  \\  \frac{a}{5b}  =  \frac{1}{4}  \\ 4a = 5b \\ a =  \frac{5b}{4}  -  -  - 2 \\  \\ so \:  \:  \frac{a + y}{5}  \\  = (a + y) \times  \frac{1}{5}  \\  = ( \frac{5b}{4}  +  \frac{5x}{4} ) \times  \frac{1}{5}  \\  =  \frac{5b + 5x}{4}  \times  \frac{1}{5}  \\  =  \frac{5(b + x)}{4}  \times  \frac{1}{5}  \\  =  \frac{b + x}{4}  \\  \\ so \:  \:  \:  \frac{a + y}{5}  =  \frac{b + x}{4}

3.) Simplify the expression.
Bogdan [553]

Answer:

Option C) -cosu is correct

Therefore the simplified expression is cos(u+\pi)=-cosu

Step-by-step explanation:

Given expression is cos(u+\pi)

To find the value of the given expression :

By using the formula cos(A+B)=cosAcosB-sinAsinB

Substitute A=u and B=\pi in the above formula we get

cos(u+\pi)=cosucos\pi-sinusin\pi

=cosu(-1)-sinu(0)  ( here cos\pi=-1 and sin\pi=0 )

=-cosu-0

=-cosu

cos(u+\pi)=-cosu

Therefore option C) -cosu is correct

Therefore the simplified expression is cos(u+\pi)=-cosu
