Order of operations is one way
Answer:
When 
Step-by-step explanation:
When 
is smaller than 
, the resulting value under the square root will become negative. Since it is impossible to take the root of a negative number, the expression is thus undefined, however, it can be represented with the imaginary number 
where = 
.
Hope this helps :)
The gradient is also known as the slope and we can find it using the slope/gradient formula: (y2 - y1) / (x2 - x1)
To find the gradient/slope, we need to first choose two points on the line. You can choose any two points you like, as long as they are on the line you are trying to find the slope of.
Point 1 = (2,2)
Point 2 = (5,8)
Now, we can plug in these points to the formula and solve.
(8 - 2) / (5 - 2)
6 / 3
2
The gradient of the blue line is 2.

X=8
80+57= 137
180-137= 34
5x8-6=34
Let p = pictures only
let f = pictures with frames
p + f = 100
5p + 10f = 875
Solve for one variable in the first equation then plug into the second
p = 100 - f
5(100 - f) + 10f = 875
500 - 5f + 10f = 875
500 + 5f = 875
5f = 375
f = 75
75 pictures with frames were sold
