Answer:
For the first one the slope is 4
For the second one the slope is 0
Step-by-step explanation:
Subtract 4x from both sides of the equation
<em>-</em><em>y</em><em>=</em><em>6-4x</em>
Multiply each step in <em>-</em><em>y</em><em>=</em><em>6-4x</em><em> </em>by <em>-</em><em>1</em>
<em>y</em><em>=-6</em><em>+</em><em>4x</em>
For slope intercept form <em>y</em><em>=</em><em>mx</em><em>+</em><em>b</em><em> </em>or <em>y</em><em>=</em><em>4x</em><em>+</em><em>6</em>
Slope : 4
Y intercept is (0,6)
To find the x intercept substitute in 0 for y and solve for x. To find the y intercept substitute in 0 for x and solve for y
X intercept: (9/5, 0)
Y intercept: (0,-9)
Slope is 0 using the formula y=mx+b
We have the function:
The parent function is the linear parent function p(x)=x.
We can see that f(x) is 7 units above p(x) for any value of p(x), so we can transform p(x) to f(x) by a translation of 7 units in the y-axis.
We can see this in the graph:
Then, the transformation is a vertical shift up 7 units.
Answer:
cost = $10
Step-by-step explanation:
let cost be x
Price = x+ (0.5x)= 1.50x
cost reduced in term of x is 20% of 1.50x
* 1.50x = 0.3x
hence 1.50x - 0.3x = 12
1.2x=12
x= 
= 10
cost = $10
Answer:
0.0482
Step-by-step explanation:
Given the following :
Probability of success : p(success) = 0.25
Number of trials = 800
X = number of successes
Calculate P(X > 220)
The problem above can be solved using the binomial probability formula:
P(X > 220) = P(X = 221) + P(X =222)... + P(X =800)
To save computation time, we coild use the online binomial probability calculator :
P(X > 220) = 0.0482
The binomcdf function of a graphing calcukatur can also be used :
1 - binomcdf(800, 0.25, 220)
1 - (0.95177363855) = 0.04822
