Answer:
a=0.15 per unit
b=0.13
Step-by-step explanation:
4.19 divided by 28 is 0.15
9.12 divided by 72 is 0.13
Answer:
y = 2 x - 9
Step-by-step explanation:
slope = difference of y / difference of x
m = (-5 - (-1)) / (2 - 4) = -4 / -2 = 2
pass point (4 , -1)
y = mx + b b: y intercept
b = y - mx = -1 - 2 x 4 = -9
equation: y = 2 x - 9
Answer:
The length of hypotenuse is 12.5
Step-by-step explanation:
First 7.5 x 7.5 = 56.25
Then 10 x 10 = 100
Add them together 56.25 + 100 = 156.25
Then square root 156.25 and you get 12.5
Answer:
12.5 in.
Step-by-step explanation:
You could use the pythagorean theorem, or you can use scale factor. The scale factor between side A and A' is 7.5/3=2.5, which is your scale factor. Multiplying 2.5 by your original hypotenuse gives you 12.5
The artist should graph the point (-6.5, 2) by starting at the origin, moving 6.5 units to the left (negative x-axis), and 2 units up (positive y-axis). This process is usually referred to as plotting data pairs.
The artist could graph this point on a coordinate plane, using the numbers as coordinates. The first coordinate (-6.5) refers to the position on the x-axis (horizontal line), and the second coordinate (2) refers to the position on the y-axis (vertical line).
To plot the point, the artist should start at the origin (the point where the x and y axes intersect, usually denoted as (0,0)), move 6.5 units to the left (as -6.5 indicates a movement towards the negative direction of the x-axis) and then move 2 units up (as the y-coordinate is positive).
Graphing points is a key component of various mathematical activities such as constructing line graphs or creating geometric designs. The process of plotting data pairs can be used to represent relationships between different variables.
