x=6
3) x^2-8x+13=0 —> x= (8±√64-4(1)(13))/2(1)
x=4±√3
5) x^2-6x+9-k=0 —> x=(6±√36-4(1)(9-k))/2(1) —> (6±√4k)/2 —> (6±2√k)/2
x=3±√k
7) y=x^2-4x+11 —> y-11=x^2-4x —> take the half of the coefficient of the single x term and square it and add it on both sides —> y-11+4=x^2-4x+4 —> y-7=(x-2)^2 —> y=(x-2)^2+7
Minimum: (2,7)
Maximum: n/a
X intercepts: none (never crosses the x-intercept)
9) y=x^2+2x-8 —> y+8+1=x^2+2x+1 —> y=(x+1)^2-9
Minimum: (-1,-9)

Answer:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex], [tex]x=\frac{-17-\sqrt{97}}{6}[/tex]
Step-by-step explanation:
Use the quadratic formula to solve for all real solutions.
Quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
Plug in and solve:
[tex]x=\frac{-17\pm\sqrt{17^2-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-4(3)(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-12(16)}}{2(3)}\\\\x=\frac{-17\pm\sqrt{289-192}}{2(3)}\\\\x=\frac{-17\pm\sqrt{97}}{6}\\[/tex]
Since that's the farthest we can simplify to, your answers would be the positive and negative versions of the expression:
[tex]x=\frac{-17+\sqrt{97}}{6}[/tex]
and
[tex]x=\frac{-17-\sqrt{97}}{6}[/tex]

The temperature was recorded at the same time each day,
a)
Which temperature was the warmest?
b)
Which temperature was the coldest?
c)
How much colder was it on Thursday than on Saturday?
d)
On Sunday the temperature was 5°C lower than on Saturday.
What was the temperature on Sunday?
Answers
Answer:
a) The warmest temperature will be the one where the value of the temperature is the largest, in the table we can see that the largest temperature is 3°C on Saturday.
Then the largest temperature was on Saturday, and it was 3°C
b) Which temperature was the coldest?
Now we need to look at the smallest temperature (or the largest negative temperature). In the table we can see that the smallest temperature is -6°C on Friday.
Then the smallest temperature is -6°C.
c) On Thursday the temperature was -1°C
On Saturday the temperature was 3°C
The difference between the temperatures is:
-1°C - (3°C) = -4°C
This means that Thursday was -4°C colder than on Saturday.
d) On Sunday, the temperature was 5°C lower than on Saturday.
On Saturday the temperature was 3°C, then the temperature on Sunday is:
T = 3°C - 5°C = -2°C
The temperature on Sunday is -3°C.

Answers
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
Solution:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.

Simplify (use only positive exponents) : (3y^10)(2y^2)/8y^5
please explain how you did it so that I can understand what I'm doing <3
Answers
So;
(3y^10)(2y^2) is equal to (3)(2)(y^10+2).
6y^12/8y^5
When dividing exponents, you do the opposite and subtract the exponents. And you divide the whole number by half.
6y^12/8y^5 = 3y^7/4

Step-by-step explanation:
Density is the amount of mass in a certain volume. Density is recorded in units of grams per milliliter
(g/mL). What is the density of an object is its mass 100g and its volume is 50mL?
a 0.5 g/mL
b 2 g/mL
c 50 g/mL
d 5,000 g/mL
Answers
Answer:
Density = mass/volume
Density = 100g/50mL
Density = 2g/mL, so b is correct
Let me know if this helps!
Answer:
b. 2 g/ml
Step-by-step explanation:
As we know density is defined as mass per unit volume so here
Density is recorded in units of grams per milliliter
So Now
Mass (m) = 100 g
Volume (V) = 50 ml
Density (d)
= m/v
= 100 / 50
= 2 g /ml
