Answer:
49/8 is the value of k
Step-by-step explanation:
We have the system
x = -2y^2 - 3y + 5
x=k
We want to find k such that the system intersects once.
If we substitute the second into the first giving us k=-2y^2-3y+5 we should see we have a quadratic equation in terms of variable y.
This equation has one solution when it's discriminant is 0.
Let's first rewrite the equation in standard form.
Subtracting k on both sides gives
0=-2y^2-3y+5-k
The discriminant can be found by evaluating
b^2-4ac.
Upon comparing 0=-2y^2-3y+5-k to 0=ax^2+bx+c, we see that
a=-2, b=-3, and c=5-k.
So we want to solve the following equation for k:
(-3)^2-4(-2)(5-k)=0
9+8(5-k)=0
Distribute:
9+40-8k=0
49-8k=0
Add 8k on both sides:
49=8k
Divide both sides by 8"
49/8=k
The answer is C. 155
First find the measure of arc YZ.
The arc of WYZ is equal 180 degrees. So first add 25 to 85. Then subtract that to 180.
25+85=110
180-110=70.
Next add 70 to 85 since you want to find the measure of ZX.
70+85=155
So measure of ZX is equal to 155 degrees

Answer:
12x + 96 ≥ 200
Step-by-step explanation:
Each ticket costs 12 each= 12x
He has already sold 96=+96
he needs to make 200
12x+96>= 200
