To solve this problem you must apply the proccedure shown below:
1. You have the following quadratic equation, which is given in the problem above:
<span>2y^2+6y-8=0
2. So, to solve it, you can use the quadratic formula, which is:
y=(-b</span><span>±</span>√(b²-4ac))/2a
<span>
a=2
b=6
c=-8
3. When you susbtitute these values into the formula, you obtain:
y1=-4
y2=1</span>
Answer:
The answer is 3.
Step-by-step explanation:
-2x + 7 = X-2
-2(3) + 7 = (3)-2
-6 +7 = 1
1 = 1
C is not correct
You can call it line m
You can call it PR or QR
Answer:
x < -6
Step-by-step explanation:
Whenever the value of x will be less than -6 the answer is going to be negative.
