Answer:
Step-by-step explanation:
The point-slope form of a line is given by:
Where
(x_1,y_1) is the coordinate pair (any of the points given)
m is the slope. The ratio of change in y coordinates by x coordinates
Let's calculate the slope:
Now, it is given "y - 4", so y_1 is 4, so they are using the coordinate pair (7,4). So we can say x_1 = 7
Now we have all the values, lets write the equation:
This is the point-slope form.
Answer:
$20.00
Step-by-step explanation:
t represents the total amount
0.25t = 5.00
Can you solve for t and answer?
Or logically
Peter's $5.00 is 1/4 (25%) of the total.
Therefore 4/4 is $20.00
Answer:
Step-by-step explanation:
zeroes are when you plug in that x value and get y=0
therefore if you set x = that number and solve for 0 you get a "function"
multiplying these together will yield the complete 3rd degree polynomial
x = 1
x-1=0
x=7
x-7=0
x=-4
x+4=0
If needed you could expand but I'm too lazy
Actual = 6 feet.
Measure = 5.49 feet
Error = 6 - 5.49 = 0.51
% Error = (Error / Actual) * 100%
= 0.51/6 * 100% = 8.5%
30% of 200=60 200+60= 260
Ty has £260
£260 x 2= £520
200+260+520= £980
Answer £980
I hope this is right :D
