Showing in Linear Functions

Linear FunctionsSince your function does not move left or right, the domain will remain the same as the reflection across the xaxis will still remain all real numbers except zero. A vertical compression and...

Linear FunctionsThe set of equations 9x  4y = 109 and 7x+89=y has to be solved for x and y. Substitute y = 7x+89 in 9x  4y = 109 => 9x  4(7x+89) = 109 => 9x  28x  356 = 109 => 19x = 247 => x...

Linear FunctionsKim can cycle 30 km/h faster than she can run. If the speed at which she can run is X, the speed at which she can cycle is X + 30. She spends 48 minutes running and 48/3 = 16 minutes cycling. The...

Linear FunctionsSo you have `1/2=x^2+3x+4 implies x^2+3x+7/2=0` Now you use formula for solution of quadratic equation `x_(1,2)=(b pm sqrt(b^24ac))/(2a)` where `a,` `b` and `c` are coefficients of general...

Linear FunctionsThis function indicates a linear model as if the camera's retail is $100, applying the coupon would give the camera a price of $50. If the camera price retailed at $150, the price of the camera...
