zero product property (Angela)

Hi there !

(Angela)

3x² + 10x = 0

x(3x + 10) = 0

x = 0 => x₁ = 0

3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3  1/3

Good luck !

Answer:

12w + 8d = 100

Step-by-step explanation:

Given:

Price of wall calendars = $12

Price of desk calendars = $8

Total amount pay = $100

Computation:

w = wall calendars

d = desk calendars

So,

Price of wall calendars(w) + Price of desk calendars(d) = Total amount

12w + 8d = 100

=================================================

Work Shown:

x^2 - 5x + 1 = 0

x^2 + 1 - 5x = 0

x^2 + 1 = 5x

(x^2 + 1)/x = 5    .... where x is nonzero

(x^2)/x + (1/x) = 5

x + (1/x) = 5

---------------

An alternative method involves solving the original equation using the quadratic formula. After you get the two roots x = p and x = q, you should be able to find that p + 1/p = 5 and also q + 1/q = 5 as well.

In this case,

p = (5 + sqrt(21))/2

q = (5 - sqrt(21))/2

Answer:

5

Step-by-step explanation:

Since this equation is not factorable, you can either use the quadratic formula, graph and look for its zeros, or other methods to get it's zeros.

But using the quadratic formula which always spits out a x value gives me:

4.791 and 0.209.

Now let's test both of these values since we have two x values.

[tex](4.791+\frac{1}{4.791})[/tex] ≈5 (4.9999)

and

[tex](0.209+\frac{1}{0.209})[/tex] ≈5 (4.9936)

Answer:

Step-by-step explanation:

If P, Q and S are collinear, then the three points lies on the same straight line.

If the Straight <P Q S is divided into 2 angles, <P Q R and <R Q S, by ray Q R, then;

<P Q R + <R Q S = 180

Given

<R Q S =x+1

<P Q R = 3x-5

Substitute the given expression into the formula and calculate x;

3x-5+x+1 = 180

collect like terms

3x+x - 5+1 = 180

4x-4 = 180

4x = 180+4

4x = 184

divide both sides by 4

4x/4 = 184/4

x = 46°

To get m∠PQR, we will substitute x = 46 into the expression for m∠PQR.

m∠PQR = 3x-5

m∠PQR = 3(46) - 5

m∠PQR = 138 - 5

m∠PQR = 133°

Hence the measure of angle m∠PQR is 133°

The measure of angle m∠PQR is 133° and the measure of angle m∠RQS is 47° on straight angle ∠PQS.

Given that, points P, Q and S are collinear, then the three points lies on the same straight line.

The straight ∠PQS is divided into 2 angles as ∠PQR and ∠RQS, by ray QR, then ∠PQR + ∠RQS = 180°

Here, ∠PQR = (3x-5)° and ∠RQS =(x+1)°

So, (3x-5)°+(x+1)°=180°

4x-4=180

4x=184

x=184/4

x=46

Now,

∠PQR = (3x-5)°

= 3×46-5

= 138-5

= 133°

Hence, the measure of angle m∠PQR is 133° and the measure of angle m∠RQS is 47° on straight angle ∠PQS.

Answer: 4.2495 feets

Step-by-step explanation:

Given the following :

Rate of change (speed) when rock hits the lake surface = - 3in/s

Distance or depth after 5 seconds :

Distance = rate of change * time

Distance = (- 3 in/s × 5) = - 15 inches

1 inch = 0.0833 feet

15 inches = (-15 * 0.0833) = - 1.2495 feets

Distance between Lisa's hand and lake surface = 3 feets :

Distance between Lisa's hand and rock after 5 seconds :

(3 feets + 1.2495 feets) = 4.2495 feets

Step-by-step explanation:

Explanation:

Points A, C, U, D, S and E are all in the bottom floor plane. A plane is a flat surface, and saying "points are coplanar" means the points are all on the same plane.

Points like R, T and B are not on the floor plane, so they are not coplanar with the other points mentioned in the previous paragraph.

In other words, point R is not coplanar with points C, D and E since R is not on the floor plane with C,D,E.

Answer:

√(-2)²+12+14=√16+14=4+14=18

Step-by-step explanation:

The value of expression (√a² + 12) + |b| when a = -2, b = 14 is 16.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

Constant: A constant is a fixed numerical value.

Variable: A variable is a symbol that doesn't have a fixed value.

Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.

Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given expression

(√a² + 12) + |b|

a = -2

b = 14

Substituting value of a and b in the expression

(√-2² + 12) + |14|

= (√4 + 12) + 14

= (√16) + 14

= 4 + 14

= 16

Hence, 16 is the value of expression (√a² + 12) + |b| when a = -2, b = 14 .

Answer:

Jenkins: 25 hours Alexanders: 20 hours

Step-by-step explanation:

To solve this problem we need to set up two equations. We know the rates of each sprinkler's output and how much total water was output. We know how many hours the sprinklers were on. We are looking for how long each sprinkler was used.

We can make a represent hours because we know the rate of sprinkler's output is per hour.

25a+40b=1425

a+b=45

Now to solve this system of equations we need to isolate a variable on one equation to plug into the other.

a+b=45

a=45-b

Now we can plug this in for a in the other equation.

25a+40b=1425

25(45-b)+40b=1425

Distribute 25 into the parenthesis.

1125-25b+40b=1425

1125+15b=1425

15b=300

b=20

Now we know that the Alexander family used their sprinklers for 20 hours. We can plug this back into the other equation to find b.

a+b=45

a+20=45

a=25

The Jenkins used the sprinklers for 25 hours, and the Alexanders used them for 20 hours.
