Answer:
80
Step-by-step explanation:Solution:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The given numbers are 78 & 80
step 2 Find the sum of the given two numbers.
sum = 78 + 80 = 158
step 3 Divide the sum by 2 to get the average.
average = 158/2
= 79
Thus, 79 is an average of positive integers 78 and 80.
y is -2/53
Step-by-step explanation:
- Step 1: Given equation is y = 2/5x-3 and x = -10. Substitute value of x to find the solution.
⇒ y = 2/(5 × -10 - 3) = 2/-53 = -2/53
Answer:
The standard form as
Step-by-step explanation:
Given: A function which is written in vertex form or intercept form.
We have to re-write it in standard form that in terms of
Given ![y = 5(x+3)^2-4](https://tex.z-dn.net/?f=y%20%3D%205%28x%2B3%29%5E2-4)
Squaring using
, we get,
![y=5(x^2+9+6x)-4](https://tex.z-dn.net/?f=y%3D5%28x%5E2%2B9%2B6x%29-4)
Multiply 5 inside , we get,
![y=5x^2+45+30x-4](https://tex.z-dn.net/?f=y%3D5x%5E2%2B45%2B30x-4)
Solving further , we get,
Thus , we have obtained the standard form as
You’d plug in the 0.6 for x. so you’d multiple 0.6 times 2.5 then you’d get 1.5 then you’d add 1.5 plus 5.8 and get 7.3
