14. E.because 6.7. none the answers are up there!
15.E. because 10 over 25 which mean divide by 5 equals 2 over 5
My say is that 8*7=56 so it would there for be the answer
Answer:
The equation is y = -5x + 55
Slope = -5
y-intercept = 55
Step-by-step explanation:
The given table shows the different coordinates of points on a straight line.
The general equation of a line is y = mx + b
where m is the slope and b is the y intercept.
Actually , here only 2 values are needed but there are 4 values given which is just to check whether our line is correct or not.
Substitute values of x and y in the equation.
Put (1,50),
50 = m + b ----------(1)
Put (2,45),
45 = 2m + b -----------(2)
Solve (1) and (2),
Slope , m = -5
y-intercept , b = 55
Hence , the equation is y = -5x + 55.
Answer: 133/2π
Step-by-step explanation:
<u>Area of ends:</u>
Area of Circle = πr²
π3.5²=49/4π
There are two ends so you multiply that by 2 to get 49/2π
<u>Area of Rest:</u>
First, you need to find the circumference using the equation: πd
πx7=7π
Then to find the area you just need to multiply 7π by the height
7π x 6 = 42π
<u>Total surface area</u>
You now just need to add them together
49/2π + 42π = 133/2π
