Answer:
The answer is x + 4y = 7
Equation of a line is y = mx + c
Where m is the slope
c is the y intercept
Slope of the line between the points
(-1, 2) and (3, 1) is
Slope = 1-2/ 3+1 = - 1/4
Equation of the line using point
(-1, 2) is
y - 2 = -1/4(x + 1)
4y - 8 = - x - 1
x + 4y = 7
Hope this helps you
Answer: $100
Step-by-step explanation:
<em>LET,</em>
Total Amount needed by MISS KENDRICK = 'X' = $1345
Amount which is already saved by MISS KENDRICK = 'Y' = $145
Number of weeks for the purchase = 'Z' = 12
<em>Now,</em>
AMOUNT needed to be saved each week = 
By Substituting the values in the equation, we get
AMOUNT needed to be saved each week = 
= 
= $100.
Answer:
- <u>They can catch up with the bus at 10:40 am.</u>
Explanation:
1. Set the time when Liana and her mother can leave (8:40 am) as t₀ = 0; thus the time of driving for them will be t.
2. The average speed at whic Liana's mother drive: 60 miles/hour
3. Thus, the distance they will have driven will be:
- distance = average speed × time = 60t
4. The time the bus left was 8:00 am, which is 40 minutes before Liana and her mom can leave.
Thus, the time wil have driven when Liana and her mom have driven t hours minutes will be: t + 40 min / 60 min/ hour = t + 2/3
5. The average speed of teh bus is 45 miles / hour
6. The distance the bus will have driven will be:
- distance = average speed × time = 45(t + 2/3)
7. When Liana and her mother catch up with the bus, the distances driven by both of them are equal:
Thus, Liana and her mom can catch up with the bus after 2 hours, since 8:40 am; this is, 10:40 am.
the zero(s) of function 
is x=2
Step-by-step explanation:
We need to find the zero(s) of function algebraically.
We are given:
To find the zeros we put the function equal to zero.
So, the zero(s) of function is x=2
