Answer:
Step-by-step explanation:
0+5+1+2+4+0+1+3+2+2+0+1+5+3+4+4+2+1+6
which is 46
46/19
because there are 19 numbers

Answer:
(C) -6
Step-by-step explanation:
Given the following data;
Points on the graph (x1, y1) = (1, -9).
Mathematically, the equation of a straight line is given by the formula;
y = mx + c
Where;
m is the slope.
x and y are the points
c is the intercept.
To find the zero of the linear function f, we would use the following formula;
y - y1 = m(x - x1)
Substituting into the formula, we have;
y - (-9) = -3(x - 1)
y + 9 = -3x + 3
y = -3x + 3 - 9
y = -3x -6 = mx + c
Intercept (c) or zero of a function = -6
Using equations to solve the word problem, Katherine's age is 8 years
<h3>Word Problem</h3>
Word problem are often mathematical problem that are represented in words and sometimes can be solved using an equation.
To solve this problem, we have to represent the problem using mathematical equations;
Let;
Katherine's age = x²
Alexandra = 5(x + 1)
Sum of their age = 109
5(x + 1) + x² = 109
5x + 5 + x² = 109
x² + 5x - 104 = 0
Solving for the equation; x = 8
Katherine's age is 8

#SPJ1
Total charge at park, T = 2×charge on adults + 4×charge on children .
T =$(2×16 + 4×10)
T = $72
Now, Melissa's father paid $100 .
Amount her father get back is :
A = $( 100 - 72 )
A = $28
Therefore, her father get $28 back.
Hence, this is the required solution.
Hello there! The answer would be B) translation and dilation.
When shapes are congruent, they are the same shape and size. To be changed where the shapes are no longer congruent , the size or shape has to change. In the options you've provided, B would be the correct option since it is the only one that includes changing size, when mentioning dilation (or making something bigger, hence changing it's size). In the other options, which include reflection and translations and rotations, they just change the placement of the shape, but other than that the shape is the same as the others.
I hope this helps, have a great day!
