Answer:
A
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
obtain (5 + x)(5 - x) = 7 in this form by expanding the factors
25 - x ² = 7 ( subtract 7 from both sides )
18 - x² = 0 ( multiply through by - 1 )
x² - 18 = 0 ← in standard form
with a = 1, b= 0 and c = - 18 → A
Answer:
70/100 (58)
0.70 (58)
Step-by-step explanation:
I believe the answer is B.
Because the patient loses 2% every month. There’s 12 months in a year. 2 x 12 is 24. In a year he loses 24 percent, 100%- 24% = 76%. Which the answer the rest to be 76%
Answer:
There are 5 steps. The solution is (5/4,5)
Step-by-step explanation:
1. In the y+5x=x+10 equation, subtract 5x from both sides to get y=-4x+10.
2. Set y=-4x+10 and y=4x equal to each other to get -4x+10=4x
3. Add 4x to both sides, which leaves you with 10=8x
4.Divide both sides by 8 to get x=10/8 or 5/4 when you simplify
5. Plug 5/4 into the y=4x equation and multiply 5/4 by 4/1, which leaves you with 20/4, or 5.
So the solution to this problem is (5/4,5). If you graph these two equations, you will get the same solution.
