Equation A find “m” and “b”:
“B” is the y-intercept when x = 0. They give this in the table as “-2” so b = -2
Find slope (m) = (-8)-(-2)/(-2)-0 = 3
Equation A is y = 3x - 2 (y = mx + b)
Equation B find “m” and “b”:
Find m = (-9)-(-5)/(-3)-(-1) = 2
To find be, plug in m, x, and y from ANY coordinates in table b into y = mx + b:
-9 = 2(-3) + b
-9 = -6 + b
b = -3
Equation b is y = 2x -3
Use substitution and substitute all of equation “b” for “y” in equation a:
2x - 3 = 3x - 2
Algebra: x = -1
Plug back into equation a:
y = 3(-1) -2
y = -5
x = -1
(-1, -5) final answer (B)
(20x10)+(15x10)= y
the variable is the answer or represents it
(20x10)+(15x10)
20x10=200
+
15x10=150
=
350
no they do not have enough they need 50 more dollars in order to have enough.
Answer:
To find the radius, just take half of the diameter. The answer is 2.
Step-by-step explanation:
Semicircle Area and Perimeter
Area (A)
6.2832in²
A = πr²/2 = 2 * π [in²] ≈ 6.2832 [in²]
Perimeter (L)
10.2832 in
L = πr + d = 2 * π + 4 [inch] ≈ 10.2832 [inch]
Hope this helped!!!
The given sequence is not arithmetic sequence
<em><u>Solution:</u></em>
Given sequence is:
We have to find if the above sequence is arithmetic sequence or not
An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant
<em><u>Here in the given sequence</u></em>
<em><u>Let us find the difference between terms</u></em>
Thus the difference between terms is not constant
So the given sequence is not arithmetic sequence
The ratio of the smaller to the larger is given as 2:4. Another way to write this is as a fraction:
which of course you can see now will reduce to
. That's your ratio.
