Answer:
She bought 24 Tangram puzzles
Step-by-step explanation:
Let the number of Tangram puzzles be t and the number of IQ puzzles be i
The sum of all the puzzles is 40;
i + t = 40 ••••••(i)
Cost of all Tangram puzzles at a cost of $4 per one will be;
4 * t = $4t
cost of all Iq puzzles at a cost of $2 per one is
2 * i = $2i
Sum
paid for all is $128
so;
4t + 2i = 128 •••••••(ii)
From equation i;
i = 40-t
Substitute into ii
4t + 2(40-t) = 128
4t + 80 - 2t = 128
2t = 128-80
2t = 48
t = 48/2
t = 24
<h3>Answer:</h3>
- Vertical scaling by a factor of 1/2
- Vertical translation 5 units downward
<h3>Explanation: </h3>
Multiplying a function value by a constant effectively applies a vertical scale factor to that function. The scale factor is the constant. Here, the parent function x² is multiplied by 1/2 (to give 1/2x²). The vertical scale factor is 1/2.
Adding a constant to a function value causes a vertical translation of that function. Every output value is moved upward (translated) by the amount that is added. Here, that added amount is -5, so the vertical movement is downward 5 units.
For f(x) = x², vertical scaling by a factor of 1/2 makes it 1/2x². Translating that downward 5 units makes it ...
... y = 1/2x² - 5 . . . . . . . . . x² scaled and translated
