Illusion [34]3 years ago

A negative divided by a negative is always a positive. 4 can go into 18 only 4 times to get 16 with a remainder of 2. 2 is half of four, therefore -4 can go into -18 4.5 times. 
The answer is 4 1/2 or 4.5.
I hope this helps ^-^

Can anyone help me with inverse function please? ​
12345 [234]

{h}^{ - 1} oh(x) = x \\  {h}^{ - 1} (4x + m) = x \\ 2k(4x + m) +  \frac{5}{8}  = x \\ 8kx + 2km +  \frac{5}{8}  = x

k and m must satisfy 8k = 1 mean k = ⅛

and 2km+⅝=0 mean m = -5/2

Can someone please explain?
geniusboy [140]

This is an isosceles triangle. The angles at the base are congruent (they have the same measures).

Look at the picture.

We know: The sum of the measures of angles in a triangle is equal 180°.

Therefore we have the equation:

2x-10+2x-10+3x+25=180       <em>combine like terms</em>

(2x+2x+3x)+(-10-10+25)=180

7x+5=180           <em>subtract 5 from both sides</em>

7x=175              <em>divide both sides by 7</em>

x=25

m\angle A=2x-10\to m\angle A=2(25)-10=50-10=40\\\\m\angle C=m\angle A=40\\\\m\angle B=3x+25\to m\angle B=3(25)+25=75+25=100^o

<h3>Answer: D. m∠C = 40</h3>
