An item that costs $205000, when discounted 15 percent, will cost $174250. The easiest way of calculating discount is, in this case, to multiply the normal price $205000 by 15 then divide it by one hundred. So, the discount is equal to $30750. To calculate the sales price, simply deduct the discount of $30750 from the original price $205000 then get $174250 as the sales price. which mean is C
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
Answer:
I am so sorry
Step-by-step explanation:
I dont really know what it is but I think it is 21.98 you do 7 times 3.14
I'll go by boxes (top statement box is #1, top reason box is #2, etc.)
If you don't have enough boxes, you can omit (remove) the first 2 I wrote, which is the given
1. 8y = 9x - 14; y = 5
2. Given
3. 8(5) = 9x - 14
4. Substitution
5. 40 = 9x - 14
6. Simplification (or multiplication)
7. 54 = 9x
8. Additive property of equality
9. 6 = x
10. Division property of equality
11. x = 6
12. Symmetrical property of equality
Hope this helps (:
