6 more inches because if you add from 36 to 42 it gives you 6
<span>Factor out 2
x^2 +4x -6 = 0
Take half middle coefficient and square it:
x^2 +4x +4 -6 = 4
(x+2)^2
= 10
x+2
= sqrt(10)
x
= +-sqrt(10) -2</span>
Answer:
.....................
10)=(-3)^2.x^4×2.y^2(5.x^2y^6)-7^2x^5×2y^4×2
=(9×5)x^8+2y^2+6-49x^10y^8
=45x^8+2y^2+6-49x^10y^8
=45x^10y^8-49x^10y^8
=-4x^10y^8
Answer:
y = 60x + 22
262 miles
Step-by-step explanation:
Given that the car enters the turnpike at 22 miles, his initial starting point, or initial value (b) is 22. You also know the rate at which the car travels is 60 miles per hour, which is the slope (m). Using the slope-intercept formula of a linear function: y = mx + b, you can plug in your initial value and rate:
y = 60x + 22, where y = the total miles and x = the number of hours traveled
After 4 hours:
y = 60(4) + 22 = 240 + 22 = 262 miles
