Example:
x^2 + 5x + 6 = 0
(x+3)(x+2) = 0 .... factor
x+3 = 0 or x+2 = 0 ... zero product property used here
x = -3 or x = -2 .... solve each equation for x
------
In general, the zero product property is that if A*B = 0, then either A = 0 or B = 0.

do any of y’all know how to do number 7?
Answer:
f(-3) = 2
f(-1) = 2
f(8) = 1
Step-by-step explanation:
Yep! For any function f(x), you find the y value corresponding the x value. For example, in this question, it asks us to find f(-3). Therefore, you go to the line, x = -3, and see where it intersect the function (the y value). Your answer would be the y value.
The value corresponding to f(-3) seems to be 2.
The value corresponding to f(-1) seems to be -2.
The value corresponding to f(8) seems to be 1.

is 5/x+y=-7 linear or nonlinear
Answer:
Not linear.
Step-by-step explanation:
A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 , the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not a linear equation.
2. 1. POINT A HAS COORDINATES (4,6) AND POINT O IS AT THE ORIGIN. FIND THE DISTANCE FROM O TO A. A 6
Answer:
√52 units
Step-by-step explanation:
Here we want to find the distance between two points;
O(0,0) and A (4,6)
We can use the distance formula to find this;
D = √(x2-x1)^2 + (y2-y1)^2
D = √(4-0)^2 + (6-0)^2
D = √(16 + 36)
D = √52
So the distance between the two points is √52 units

Suppose you had two circular objects. Let the first circular object have a diameter of 26 cm and let second circular object have a diameter that is half as long as the diameter of the first. What would the circumference be for the second item in centimeters?
Answer:
40.82cm
Step-by-step explanation:
half of 26 is 13
the second's circle diameter is 13
the formula for circumference is C = 2πr
where r is the radius and π is 3.14
diameter =2r
13 = 2r
r = 6.5
2 x 6.5 x 3.14 = 40.82
40.82 cm

How can you solve a system of two equations or inequalities in which one is linear and one is quadratic?
Answer:
Solve the inequality as though it were an equation. The real solutions to the equation become boundary points for the solution to the inequality. Make the boundary points solid circles if the original inequality includes equality; otherwise, make the boundary points open circles.

Find the measure of DCH.
===================================================
Work Shown:
Angles DCH and PCF are congruent because they are vertical angles.
angle DCH = angle PCF
5h+94 = 7h+80
94-80 = 7h-5h
14 = 2h
2h = 14
h = 14/2
h = 7
angle DCH = 5h+94
angle DCH = 5*7+94
angle DCH = 35+94
angle DCH = 129 degrees
angle PCF = 7h+80
angle PCF = 7*7+80
angle PCF = 49+80
angle PCF = 129
We get the same result for both angles, which confirms the correct h value.

Find the coeficcient of the x4y3 term in the expansion of (2x+y)7
By the binomial theorem,
[tex]\displaystyle (2x+y)^7 = \sum_{k=0}^7 \binom7k (2x)^{7-k} y^k=\sum_{k=0}^7 \binom7k 2^{7-k} x^{7-k} y^k[/tex]
where
[tex]\dbinom nk=\dfrac{n!}{k!(n-k)!}[/tex]
is the binomial coefficient.
We get the x⁴y³ terms with k = 3, for which the coefficient would be
[tex]\dbinom73 2^{7-3}=\dfrac{7!}{3! 4!} 2^4=\boxed{560}[/tex]
Kelly wants to decrease her daily sugar intake from 40 grams of sugar to 30 grams of sugar. By what percentage does Kelly want to decrease her daily intake of sugar? O 10% O 25% O 75% O 905
Kelly wants to reduce her sugar consumption by 25%.
Kelly wants to go from consuming 40 grams to 30 grams of sugar.
The percentage she wants to decrease by can be found by the formula:
= (Old intake - New Intake) / Old Intake
Solve the formula and the percentage is:
= (40 - 30) / 40
= 0.25
= 25%
In conclusion, Kelly wants to decrease her sugar intake by 25%.

Which two integers is 8 between
1. In winter with heavy snow,
the animals in Yellowstone cannot freely roam to find food,
so hay is dropped for them from helicopters. A helicopter is 180 feet above the ground
drops a bale of hay while the helicopter itself is rising at 32 feet per second. The height (S)
in feet of the bale as a function of time is given by:s(t) = -16t2 + vit + Si
where t is the time since the bale was dropped off the helicopters (in seconds), V is the
initial velocity, and Si is the initial height.
