Function a is linear, the equation is y = 5/3x or y=5/3x+0
First multiply it to get how much the discount is
so 94*.15= 14.25 then subtract
94-14.25= 79.75
so Rob spent $79.75 after using his coupon
P.S- That's probably a gold racket! LOL
4/3
1.3 repeating
1 1/3
These are all correct. To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one. Or just use a calculator lol.
Answer:
(√6)/2 square units
Step-by-step explanation:
The area of a triangle is half the magnitude of the cross product of the vectors representing adjacent sides.
QR = (4-3, -1-(-4), -4-(-5)) = (1, 3, 1)
QS = (3 -3, -5-(-4), -6-(-5)) = (0, -1, -1)
The cross product is the determinant ...
The magnitude of this is ...
|QR × QS| = √((-2)² +1² +(-1)²) = √6
The area of the triangle is half this value:
Area = (1/2)√6 . . . . square units
$135 per month
by dividing the pay off balance by the 15 months it was required
