Answer:
x = .4384471872, x = 1, x = 4.561552813
Step-by-step explanation:
(x-1) is a root. When you divide it into x³-6x²+7x -2, you are left with x²-5x+2. Use the quadratic equation on that.
(5+/-)/2
So the roots are (5 - )/2, 1, and (5 + )/2
Answer:
No Petra is wrong
Step-by-step explanation:
The associative property of multiplication goes thus :
(x * y) * z = x * (y * z)
The equation give in the question :
(9.5 x 9) + 1 = 9.5 * 10
The associative property cannot be used to rewrite the equation as claimed above.
Because, the equation includes both multiplication and addition functions. Hence, it has to be solved separately following tbe rule of BODMAS., THE sign preceeding 9 in the equation is multiplication and as such not mathematically correct to add such number to +1
To ascertain :
(9.5 x 9) + 1 = 86.5
9.5 * 10) = 95
Hence,
(9.5 x 9) + 1 ≠ 9.5 * 10
Expanded form means writing out a number in words. So, in expanded form, 4,408,730 will be:
four million, four hundred eight thousand, seven hundred thirty
It helps to figure this out if you say the number out loud, and then simply write down what you said.
Answer:
2
Step-by-step explanation:
Given two points on the line, we can use the slope formula
m = ( y2-y1)/(x2-x1)
= ( 7 - -3)/(3 - -2)
= (7+3)/(3+2)
= 10/5
=2
Answer:
37.5 Miles Per Gallon
Step-by-step explanation:
The Mileage of a car is the total number of miles driven divided by the total number of gallons (liters) of gas used.
For this problem, the units is miles per gallon
Allison can drive 450 miles with 12 gallons of gas. So
Total Miles Driver = 450 miles
Total Gas = 12 gallons
Hence, the mileage would be 450 divided by 12:
Mileage = 450/12 = 37.5 Miles Per Gallon
