10 - x = d (d= difference of 10 and x)
I think this right, sorry if it's wrong :/
The constant of proportionality is known as the slope of the line.In the graph constant of proportionality is 1/2
<h3>What is constant of proportionality?</h3>
The constant of proportionality is known as the slope of the line.
Constant of proportionality is nothing but slope of a line
The formula for calculating slope is expressed as:
m = y₂-y₁/x₂-x₁
Given the coordinate points (2/3, 3/4 ) and (0,0).
y₂=0, y₁=3/4, x₂=0,x₁ =2/3
substitute the values of y₂=0, y₁=3/4, x₂=0,x₁ =2/3 in slope formula to get constant of proportionality.
The constant of proportionality is expressed as:
m = 3/4 × 2/3
m =6/12
m=1/2
Hence the constant of proportionality is 1/2

#SPJ1
Answer:
The correct answer is -
a. 4.5 inches.
b. side or arm (a)
c. (a) or 4.5, and 18
d. (d) 4.5, and 14.1428
e. 22/7 × r^2 = 15.90
Step-by-step explanation:
Given :
Radius or r = 2 ¼ inches
Solution:
a. the diameter of the circle -
d = 2r
= 2 ¼ *2
= 2.25*2
= 4.5
b. The diameter of the circle is the same length as one side or arm of the square which is
a = d = 4.5
c. The perimeter of the square
P = 4a = 4d = 4*4.5 = 18
d. Perimeter of the circle =
2πr = πd = (22/7)*4.5
= 14.1428
e. the area of the circle =
22/7 × r^2
= 15.90
Answer:
y = 1/3x + 5
Step-by-step explanation:
Since the slope-intercept form is y=mx+b, you need to start by rewriting this in slope-intercept form, which you can write this as 3y = 15 + x. You get this by adding X to both sides.
Then, divide everything by Y, which in this case is 3.
3y Divided by 3 is 1, or Y.
15 Divided by 3 is 5.
x, or 1x, divided by three, is 0.3 forever repeating. However, you rewrite this as a fraction, due to slope-intercept form.
That's how you get the final answer, the final answer being y = 1/3x + 5.
