Answer:
Non-linear equations:
Step-by-step explanation:
Linear equation: y = mx + b
Therefore, a linear equation has 2 variables that have no exponents.
So the non-linear equations are:
(this is a quadratic equation - polynomial with degree 2)
(this is an exponential equation)
Answer:
Step-by-step explanation:
A scale factor of 1:3 means that one triangle is 3 times bigger than the other, for example. So, if the small triangle has a perimeter of 27, the big triangle has a perimeter 3 times as big.
X = 1st number
x + 1 = 2nd number
x + 2 = 3rd number
x + (x + 1) + (x + 2) = 18...combine like terms
3x + 3 = 18
3x = 18 - 3
3x = 15
x = 5
x + 1 = 5 + 1 = 6
x + 2 = 5 + 2 = 7
7 + 6 + 5 = 18
13 + 5 = 18
18 = 18 (correct)
largest number is 7
Answer:
(3,0)
Step-by-step explanation:
The midpoint formula is as follows:
x1 would be 9, x2 would be -3, y1 would be 2, y2 would be -2. When plugged in, you should get 6/2, and 0/2 for y. When simplified, x would be 3 and y would be 0. This means that the midpoint of the line segment is (3,0)
Answer:
1/10.
Step-by-step explanation:
Prob(Spinning a 1) = 1/5.
Prob(Flipping a Head) = 1/2.
Probability of a 1 then a head = 1/5 * 1/2 = 1/10.
Note: we multiply the probabilities because the 2 events are independent.
