F(x) = 5x
for f(7) you replace x with 7 so it will be : f(7) = 5(7) = 35
What the sum and then i can tell you
Answer:
Step-by-step explanation:
Number of red balls = 4
Number of green balls = 6
Total number of balls = 6+4 =10
Probability of drawing a green marble is given as
⇒
⇒
The ball is replaced after drawing.
Probability of drawing a green ball a second time will be:
⇒
⇒
Thus, probability of drawing 2 green balls with replacement can be given as:
⇒ (Probability of drawing a green marble) (Probability of drawing a green ball a second time)
⇒
⇒
Simplifying fraction by dividing numerator and denominator by their GCF.

Answer:
Step-by-step explanation:
Here we are given a equation which is ,
We need to find out the equation of the line which is parallel to the given line and passes through the given point .
- And as we know that the slope of two parallel lines are equal .
On comparing the given equation with slope intercept form (y = mx + c )of the line , we have ,
Therefore the slope of the parallel line will be ,
Now we can use the <u>point </u><u>slope </u><u>form </u>of the line which is ,
Substitute ,
This is the required answer .
