<h2>Examining the equation</h2>
We have 2 terms:
and 
For the sum of these to equal a negative number, in this case -3, one of these terms would have to be negative.
<h2>So what's the problem?</h2>
The function 
(square root of x) only returns positive values!
(See the attached image for a graph of )
Since neither of the terms can be negative, it can't be equal to -3. In other words, no matter what we put as 
, we can't solve the solution, so we say that the equation <em>does not have any solutions.</em>
Answer:
14 boys paid for the full year fee and 4 boys paid for the partial year fee
Step-by-step explanation:
Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:
24x + 16y = 400
x = y + 10
Solve by substitution by plugging in y + 10 as x:
24x + 16y = 400
24(y + 10) + 16y = 400
Solve for y:
24y + 240 + 16y = 400
40y + 240 = 400
40y = 160
y = 4
Then, plug in 4 as y to find x:
x = y + 10
x = 4 + 10
x = 14
So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.
Answer:
i think its 6.5
Step-by-step explanation:
42/7 = 6
3/6 = 0.5
6+0.5=6.5
Answer:
option C
Step-by-step explanation:
Total number of items = 5
Number of items to choose = 2
Therefore, the number of combinations is
Ok so the lines with two triangles are parralel to eachother. The lines with one are parallel to eachother.
The angle of 109° and angle of z° equal eachother. Z=109°
Since 109°, 33° and y° form a triangle, the sum of the angles will equal 180. Add 109 and 33 to get 142. Subtract 142 from 180 to get y°=38°.
Since z=109, this means that the triangle is congruent with the other. Since the congruent triangles are in a rhombus, then the angles are flipped. Thus, angle x =33°.
z=109°
y=38°
x=33°
