Answer:
y=2x-1
Step-by-step explanation:
y=mx+b
insert Point (0,-1)
-1 = m * 0 + b
-1 = b
slope:
m = delta y / delta x
m = 2 / 1
m = 2
Answer: 6
Step-by-step explanation:
2*3*6=12
12/2=6
formula= b*h/2
Answer: y=85
Step-by-step explanation: Substitute all x's in the equation with 8. y=2.5(8)+65. And solve y=85
Answer:
Least possible value of b is 9.
Step-by-step explanation:
It is given that
and b is an odd integer.
We need to find the least possible value of b.
We have,

Isolate variable terms.


Divide both sides by 3.

Since b>8 and b an odd integer, therefore the possible values of b are 9, 11, 13, 15, ... .
Hence, the least possible value of b is 9.
Step-by-step explanation:
∫₀² x f(x²) dx
If u = x², then du = 2x dx, and ½ du = x dx.
When x = 0, u = 0. When x = 2, u = 4.
∫₀⁴ ½ f(u) du
½ (16)
