- m - slope
- b - y-intercept
Step-by-step explanation:
<u>Step 1: Define</u>
Function [SIF]: y = 3x + 5
<u>Step 2: Break Function</u>
<em>Identify Parts</em>
Slope <em>m</em> = 3
y-intercept <em>b</em> = 5
Answer: x=3.2 AC= 42.8
Step-by-step explanation:
As point B lies at segment AC AC=AB+BC
Otherwise we can write the equation
5x+9x-2=11x+7.6
14x-2=11x+7.6
14x-2+2=11x+7.6+2
14x=11x+9.6
14x-11x=11x-11x+9.6
3x=9.6
x=9.6:3
x=3.2
AC= 11*x+7.6= 11*3.2+7.6=35.2+7.6=42.8

Answer:
25 chairs
Step-by-step explanation:
If 40 chairs are bought for Rs 10000 then how many chairs must be sold for Rs 10000 so as to gain 60%?
The percent gain = 60%
Number of chairs to be sold = x
Hence:
40 chairs = 10,000
60/100= 40 - x/x × 100
0.6= 40 - x/x
Cross Multiply
0.6x = 40 - x
0.6x + x = 40
1.6x = 40
x = 40/1.6
x = 25 chairs
Answer:
a. 36°
Step-by-step explanation:
The same figure will reappear when rotated 360°/10 = 36° about the center.
___
<em>Comment on the question</em>
The question as worded is nonsense. If the figure is rotated at all, there is not enough information to tell what the angle of rotation might be.
