Answer:
y = -3x + 20
Step-by-step explanation:
All you need to do is plug the (x,y) coordinates of (5,5) into the slope intercept formula to find the value of b to make the equations. Also, M is the value of the slope which is given to you as the value of -3.
1. The first 5 in the coordinate is the value Y and the second 5 in the coordinate is the value of Y. Substitute these numbers into the formula and solve.
(multiply -3 * 5)
(add 15 to both sides)
(this is the value of b)
2. Now just combine everything to form the equation
Answer:
15
Step-by-step explanation:
5a - 10b = 45
5a - (10×3) = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15
To find the average, add them all up. 13 + 7 + 12 + 9 + 8 + 8 + 16 = 73
Then divide by how many numbers there are, 73 divided by 7 = 10.4285714286
10.4285714286 rounded to the nearest tenth = 10.4
Hope this helps :D
Answer:
h = 20 cm
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) *h
where b1 and b2 are the two bases
We are given a =400 and b1 =27 and b2 =13
400 = 1/2 (27+13) *h
400 = 1/2 (40) *h
400 = 20h
Divide each side by 20
400/20 = 20h/20
20 =h
1. 28/15 as a decimal is <span>1.86666666666667
2.
</span><span>the number is divisible by 3. </span>
<span>Additionally, we know 120,000 is divisible by 3, 18,000 is divisible by 3, 420 is divisible by 3, and 15 is divisible by 3.
I hope this helps! I didn't do the last one my friend did but he thinks it's right. Please correct me if wrong.</span>
