Answer & Step-by-step explanation:
Let's have
C = Creepers
B = Balloons
1) 6C + 20B = 11.9
2) 2C + 15B = 6.05
Eliminate
16C + 20B = 11.9 x3
-2C + 15B = 6.05 x4
18C + 60B = 35.7
-8C + 60B = 24.2
10C/10 = 11.5/10
C = 1.15
Answer:
The answer is: The slope is undefined, the points given do not represent a function because x - x1 is 2 - 2, which is zero and division by zero is undefined.
Step-by-step explanation:
Given points: (2, -1) and (2, 5).
Find the slope m:
m = y - y1/m(x - x1)
m = -1 - 5/m(2 - 2)
m = -6 / m(0)
m - 6 / 0, division by zero is undefined so the slope is undefined.
Note that the points to not pass the vertical test in that a vertical line will pass through both points thus showing that these points are not part of a function.
Hope this helps! Have an Awesome Day!! :-)
43/2 because you need to multiply
Answer:
a : b = 19 : 7
Step-by-step explanation:
Given
4a - 5b : 5a + 4b = 1 : 3
Expressing in fractional form, that is
= ( cross- multiply )
3(4a - 5b) = 5a + 4b ← distribute left side
12a - 15b = 5a + 4b ( subtract 5a from both sides )
7a - 15b = 4b ( add 15b to both sides )
7a = 19b ( divide both sides by 7 )
a = b ( divide both sides by b )
=
That is a : b = 19 : 7
