Step-by-step explanation:
a = 1, b = 9, c = 8
with the quadratic formula;
x = -9 + \|9² - 4(1 × 8) ÷ 2(1) or x = -9 - \|9² - 4(1 × 8) ÷ 2(1)
x = -9 + \| 81 - 32 ÷ 2 or x = -9 - \| 81 - 32 ÷ 2
x = -9 + \| 49 ÷ 2 or x = -9 - \| 49 ÷ 2
x = -9 + 7 ÷ 2 or x = -9 - 7 ÷ 2
x = -2 ÷ 2 or x = -16 ÷ 2
x = -1 or x = -8
Answer:
4+16=0
4=−16=162
2=±4
Case 1 2=+4
=±2√
√=±(12√+12√)
=±2‾√+2‾√
Case 2 2=−4=43
=±23/2=±2()1/2
∵√=±(12√+12√)
=±(2‾√+2‾√)
So in all,
=2‾√+2‾√
=−2‾√+2‾√
=2‾√−2‾√
=−2‾√−2‾√
Let √=+
Squaring both sides, we have
=(+)2
0+1=2−2+2⟹
2−2=0(1)
2=1
=12
Plugging in (1) … ⟹
2−1(2)2=0
4=14
2=12
∴=±12‾√
∴=±12‾√
∴√=+=±(12+12)
This can also be shown as below
√=12+12
Or
√=−12−12 \
Answer:
5 units above the dotted line
Step-by-step explanation:
The reason for this is that there is a distance of 5 units between point B and the line so we know that when it is reflected there will be a distance of 5 as well.
We have 7y = 4x + 14;
Then, y = (4/7)x + 2;
The slope of this line is 4/7;
Because another line is parallel with the first one, the chosen slope is 4/7.
